Sasuke (TV Series)

''Sasuke'' (, pronounced sahskay) is a Japanese sports entertainment reality television show, airing since 1997, in which 100 competitors attempt to complete a four-stage obstacle course. Falling at any point during the course or running out of time on stages with set time limits, leads to elimination. Finishing the course by reaching the end and hitting the buzzer will grant you qualification to the next stage. Sasuke also has many international versions of itself, mainly called "Ninja Warrior", with 20 local shows.

Recorded at Midoriyama studios in Yokohama, it airs on Tokyo Broadcasting System (TBS), typically between Japanese television drama seasons. The show's name ''Sasuke'' is named after Sarutobi Sasuke, a fictitious ninja character in Japanese traditional storytelling. Each episode airs an entire tournament as a single special, ranging from 70 minutes in early season up to 6 hours. There have been 42 specials produced, with approximately two per year between 1999 and 2011, and one per year otherwise. The show is produced by TBS and began as a segment within the series , another sports entertainment competition, which aired on G4 in the United States under the name ''Unbeatable Banzuke''. Competitions generally start in the daytime and continue until completed regardless of weather or darkness. After Monster9's bankruptcy in November 2011, Tokyo Broadcasting System handed production over to the studio FOLCOM, who relaunched the show under the title ''Sasuke Rising.'' For the 35th tournament TBS renamed the show once again, to ''Sasuke Ninja Warrior'', aligning with the worldwide ''Ninja Warrior'' brand. The show's logo would be changed for the 36th edition, with the new logo's year being updated for subsequent editions.

History

1991–1995: origins and ''The King of Sports''

In 1991, TBS Sports employee Ushio Higuchi began developing ideas for a new sports competition. Having worked up the ladder at TBS enough to produce live sports coverage, Higuchi believed he had the pull to begin creating original series. Following his experiences producing live events such as the 1988 Summer Olympics and 1990 FIFA World Cup, Higuchi had admired seeing athletes perform record setting feats in individual sports, and decided to move forward with creating a sporting discipline that aimed to crown the best all-around athlete. His original concept was to create a variant of the multi-disciplinary sports such as the Modern pentathlon and Decathlon that would test speed, agility, strength and balance. Higuchi submitted a concept pitch to TBS for a series called ''The King of Sports'', but TBS denied the proposal stating that Higuchi would need to form agreements with athletics associations to recruit athletes. Higuchi had attempted to reach out to as many organizations as he could, including the Japanese Olympic Committee and International Olympic Committee, however all denied partnership due to the lack of portfolio on Higuchi's part, a perceived risk of injury to athletes, and a lack of benefit for the organizations themselves.

In July 1992, Ushio Higuchi was producing coverage for the 1992 Summer Olympics, in charge of key elements such as camera angles and narration. During this time, he became closely acquainted with legendary sports commentator Ichiro Furutachi. Higuchi discussed his idea with Furutachi, who agreed to collaborate and provide services as lead narrator for ''The King of Sports''. The coverage of the 1992 Olympics was a resounding success, and so with an increased portfolio and assistance from Furutachi, Higuchi resubmitted his proposal. TBS showed an increased interest in the format, but were still hesitant until athletes could be recruited. TBS suggested using less popular athletes, however Higuchi denied this request stating it would dilute his aspirations for the series.

Throughout 1993, Higuchi worked on recruiting athletes for ''The King of Sports'', and was able to secure contracts with individual teams, creating a roster of 28 athletes from Baseball, Wrestling, Boxing, Golf and Motorsports. With the backing of athletes, ''The King of Sports'' was approved, and debuted on December 29, 1993 under the new title '' Pro Sportsman No. 1''. The tournament was filmed in leftover venues from the 1964 Summer Olympics and featured a low budget. The initial tournament featured a pentathlon of five skills; Sprinting, Push-ups, Vaulting, Tug of war and Obstacle Racing. The initial obstacle course, titled "Survival Race", featured Hurdles, Balance beam, Climbing and Rope climbing, all to be complete under a time limit.

Reception to the pilot of ''Sportsman No. 1'' was mediocre, however TBS made enough revenue and saw the potential in the series. A second tournament was greenlit with a higher budget, to air as a special on New Year's Day 1995. In Japan, New Year's is spent with the family, and TBS felt that a sporting event was a safe and accessible option to capitalize on this market. ''Pro Sportsman 1995'' filmed in a larger venue, with a visual overall, styling everything in Greco-Roman decor to imitate the classical Olympics. New disciplines such as Beach Flags and Sled pulling were added to increase the number of events to seven. In addition, Higuchi secured more revered athletes to appear in side events called "Dream Showdowns", special exhibition events intended to attracted more viewers that would be aired alongside the main event. This second tournament of ''Sportsman No. 1'' was a resounding hit, dominating TV ratings for New Years Day.

With a successful series in his portfolio, Higuchi pitched the subtitle "Clash of Olympians" for the third tournament. To his surprise, the promotional manager for the Japanese Olympic Committee had watched the New Year's Day special of ''Sportsman No. 1'' and loved it, and helped Higuchi secure an official partnership. The JOC and Higuchi produced two crossover specials, with the first fast-tracked to air March 1995, starring athletes from the Summer Olympics and with new disciplines of Sit-ups and Pull-ups. The second collaboration in October 1995 tournament featuring athletes from the Winter Olympics and featured Imaginary chair as a new event.

1995–1997: concept revision and ''Kinniku Banzuke''

Through 1995, TBS received a high volume of inquiries from amateur athletes and members of the public expressing interest in competing on future installments of ''Sportsman No. 1''. TBS and Higuchi made the decision to keep only professional athletes in Sportsman No. 1, instead launching a sister program named '' Kinniku Banzuke'' which would allow members of the public to compete via public auditions.

A pilot season of ''Kinniku Banzuke'' began airing at 1:15am on July 8, 1995 as a series of eleven 30 minute pilot episodes. TBS believed that it would be an ideal late night program, as it would be a niche program targeting adult men already interested in athletics. These episodes saw Sit-ups, Push-ups, and Vaulting return from Sportsman. Qualification rounds were toured to Tohoku, Kansai, Okinawa, Hokuriku, Hokkaido and Kyushu, were the top athletes would then be invited to a final competition in Yokohama at the end of the season.

The series became an unprecedented hit, with record high viewership despite the late broadcast time. This was attributed to several factors; family and friends of competitors tuned in to cheer them on, women tuned in due to the Odagiri effect, and large numbers of youth found the show fun and aspired to compete. TBS immediately pivoted their approach and moved the series to a prime time window on Sundays beginning in October 1995. In addition, they greatly expanded the number of events returning from Sportsman, and created additional competition divisions for women and youth. They also invested in new events, most notably a backflip racing event named ''Bakuten'' that attracted success from professional gymnasts such as Yukio Iketani.

In the Spring of 1996, Higuchi decided to branch the series out to include two new categories of events. The first were variations of target practice under different sports disciplines such as Baseball and Soccer, which allowed an influx of professional athletes to compete due to the lowered risk. The second category were skill-based obstacles courses that featured 9 obstacles. Higuchi's initial concept for this was a course inspired by ''Bakuten'' that featured athletes navigating different areas such as stairs, parallel bars and ramps while in a handstand. Originally developed under the name "Handstand Jungle", the event debuted in May 1996 as ''Hand Walk''. ''Hand Walk'' was extremely popular, and so Higuchi expanded this obstacle course idea into several other disciplines; ''Super Rider'' for bike trials, ''Like a Pierrot'' for Unicycle, ''Kangaroo'' for pogo stick and ''Bamboo Derby'' for stilt walking. As expected, these events were similar popular, and so Higuchi began to expand into original course ideas, such as ''Sponge Bridge'', a precision balance course, and ''Spider Walk'', an event based on the Ninja skill of moving while perched between two walls, as was historically done to move stealthily between two buildings in an alley.

The original courses Higuchi had designed such as ''Hand Walk'' were beginning to be defeated after several filming sessions, and so he decided to employ recursive self-improvement in courses, where events would return with an increasing number in their title, featuring renewed and more difficult obstacles to keep competitors indefinitely returning to events. Due to the continued success of ''Kinniku Banzuke'' and increased funding from revenue, TBS requested that Higuchi prepare a special broadcast for March 1997 that would have an extended runtime of several hours and feature bigger special guests and larger events. Higuchi designed a grander sequel to ''Hand Walk'' called ''Hand Walk Tower'', which featured three stages of increasing difficulty. Competitors would have to complete each stage in order, and if anyone were to complete them all, they would be awarded the title of Kanzenseiha, or Total Victory. This special was extremely successful, in part due to the outstanding performance of Naoki Akiya, who achieved Total Victory on ''Hand Walk Tower''.

1997: ''Sasuke''

Almost immediately after the broadcast of ''Hand Walk Tower'', Ushio Higuchi approached Masato Inui, who had worked as assistant producer on ''Hand Walk Tower'' among other events, to immediately begin production on a new event for broadcast in a second special, to air September 1997. Higuchi's idea was to create a multi-staged course that used the all around athletic skills of competitors similar to ''Sportsman No. 1'', while being directly inspired by the different skills performed by ninjas, such as ''Spider Walk''. Like ''Hand Walk Tower'', this new project was to be a larger multi-stage course following the same format. He gave this idea to Inui to expand and create the course, while also being directed to save cost by reusing elements from previous events wherever possible.

Inui fleshed out plans for a four stage course. The course would run linearly, so that they could be filmed in a way that would mimic popular video games such as Super Mario Bros. in a similar way to TBS's previous event ''Adventure Zone'', which aired as a segment on '' Takeshi's Castle''. Stylistically, Inui took inspiration from the film Castle in the Sky, which itself was based on historic events Wales. The 1st Stage would feature urban navigation and balance skills ninjas would need to hop over barrels, climb walls, and run across rooftops, and took stylistic inspiration from running along a castle wall. The 2nd Stage was a speed based on the escape skills a ninja would require to evade capture, such as avoiding enemy weapons, crawling under raised temples, and passing heavy barricades. Thematically, the 2nd Stage was based on industrial factories. The 3rd Stage featured the precision skills a ninja would use, namely running across fenceposts, crossing hanging beams, and crossing bamboo trusses and flag poles. The Final Stage featured a tower climb similar to what a ninja would use to climb into the upper chambers of an enemy palace they are infiltrating.

Due to the cramped spaces sed to film ''Hand Walk Tower'', Inui had originally intended to film this new program on a large scale outdoor course. Unfortunately, due to the short turnaround time on production, the desired location at Midoriyama studios was unavailable, and so they had to rent Tokyo Bay NK Hall instead.

Higuchi suggested the format for the show use an idea he had called "Survival Attack", which was loosely inspired by the format of TBS's previous series '' Takeshi's Castle''. 100 individuals, the equivalent of a military troupe, would try and conqueror the course as soldiers. Attempts are ordered based on their reputation, metaphorically representing military ranks. Highly respected competitors such as Olympians and prestigious celebrities would run later, with women, and commoners running earlier. Unlike ''Takeshi's Castle'', only those who succeeded in each stage would be permitted to advance and attempt the next.

The event debuted under the title on September 27, 1997 to widespread acclaim.

1998–2002: serialization

Despite Higuchi and Inui intending ''Sasuke'' to be a one time special event, TBS was flooded with thousands calls and letters asking how they can apply for the series. The decision was made to produce a second tournament of ''Sasuke'' under a higher budget and air it during the fifth ''Kinniku Banzuke'' special in September 1998. ''Sasuke 2'' filmed outdoors at Midoriyama Studios as we originally desired, and featured an entirely new aesthetic on the course. Due to the high number of clears in the first tournament, the time limit on the 1st Stage was dropped, and the 3rd Stage was fully revamped to feature the now iconic final dismount from a bar. Competitors who were successful in the first tournament or became popular due to their charismatic appearance would receive higher numbers. ''Sasuke 2'' received a staggering 20% increase in viewership from the already high number of viewers it already had, and was able to outcompete traditional sports like baseball, leading to TBS approving an ongoing serialization of tournaments airing every Spring and Fall.

Additionally, due to extremely high demand from youth, TBS launched the new series ''Sasuke Junior ~Kosasuke~'' alongside ''Sasuke 2'', which featured 100 children between the ages of 8 and 12 competing on a scaled down course. Unlike ''Sasuke'', the first three stages were completed back-to-back, with the time continuing to run between then. The 3rd Stage was replaced with a precision trapeze swing, and the Final Stage featured a pole climb instead of a rope. ''Sasuke Junior'' aired as 6–10 minute segments at the beginning of Kinniku Banzuke episodes, leading each tournament to be broadcast over 5–8 episodes.

''Sasuke 3'' broadcast in Spring 1999 and featured the debut of the iconic Rolling Log, as well as changing the end of the 1st Stage to a shorter rope climb, which would eventually lead to the short climb at the end of the 1st Stage to become a common course element for the series.

Summer 1999 saw the release of ''Dream Team'' in Korea, a series that directly plagiarized the contents of ''Sportsman No. 1'' and ''Sasuke'' produced by Korean Broadcasting System, a network who had previously engaged in a legal dispute with TBS over the plagiarism of '' Takeshi's Castle''. While unofficial, this marked the first time that the series had created any presence outside of Japan.

Fall 1999 saw the broadcast of the ''Sasuke 4'', which debuted the obstacle Cliffhanger, which has since become a staple in all ''Sasuke'' and ''Ninja Warrior'' series worldwide. This tournament also saw Kazuhiko Akiyama become the first ever person to defeat the entire ''Sasuke'' course, and iconic moment in the series' history.

In the Spring of 2000, ''Sasuke 5'' was broadcast. This tournament embraced the recursive improvement idea from ''Kinniku Banzuke'', and featured redesigned stages. The 1st Stage saw the debut of the Warped Wall, possibly the most iconic obstacle in the series' history. Additionally, the final stage was revamped to be taller, and featured a Spider Climb prior to the rope.

In December 2001, Higuchi debuted a new special called ''Kunoichi''. The concept was generally the same as ''Sasuke'', but with the course rebalanced to the strengths of women, and themed based on the folklore of Kunoichi. Prior to this point, only a single women had ever cleared the 1st Stage on ''Sasuke'', and so the goal was to have women see the same level of success. Despite this, ''Kunoichi''s debut tournament saw only two individuals clear the 1st Stage, only to fail at the start of the 2nd Stage. As of 2025, this is still the second worst outcome of any tournament worldwide. Even with poor results, ''Kunoichi'' was a rating success, and TBS began producing new tournaments annually.

In September 2001, ''Sasuke'' reached all time peak viewership during its eighth season, with 26% of all households in Japan watching. The tournament saw actor and martial artist Kane Kosugi, most known at the time for his work on Ninja Sentai Kakuranger, advance to the final stage.

2002–2005: independence and restructuring

During a filming session of ''Kinniku Banzuke'' in May 2002, a competitor suffered a paralyzing fall on a new strength-based spinoff course called ''Power Island''. Filming was immediately suspended, and an investigation revealed two additional minor injuries. As a result, a formal safety audit was initiated by the Japanese government into potential unacceptable safety risks on the sets of ''Kinniku Banzuke''. The outcome of the investigation indicated that the majority of course events in ''Kinniku Banzuke'' would need to be reworked to be compliant with safety regulations. TBS planned to address these concerns and relaunch ''Kinniku Banzuke'' under the new title ''Taiiku World'' in the future. Since pre-production on the tenth Sasuke tournament was already underway at the time of the accident, the decision was made to launch Sasuke as an independent program in order to maintain the original broadcast window of September 2002. Despite this change, viewership did not decline for Sasuke, and so the decision was made to continue producing ''Sasuke'' biannually. Kane Kosugi, who had previously hosted several aftershows and spinoffs of ''Kinniku Banzuke'' left the franchise to focus on his acting career and to reduce the amount of training he had to do to switch between.

In July 2003, TBS went through restructuring of its internal studios. The decision was made to no longer have TBS Sports produce ''Sasuke'' or ''Taiiku World'', and instead it would be handled by new acquisition Dreamax Teleivision, a studio that had previously only created historical dramas. Due to this, Ushio Higuchi and Masato Inui were all relocated to Dreamax to assist with production. As a result of the lack of live athletics experience among Dreamax, production was halted on Taiiku World and outtakes from past events were used to fill episodes until it would end in September. ''Kunoichi'' was spun off into its own standalone program similar to ''Sasuke'' beginning with the third tournament in September 2003. Ichiro Furutachi would leave the production at this time after 11 years working alongside Higuchi, with Jay Kabira and Yuko Mizuno replacing him.

In October 2003, Dreamax launched ''Golden Muscle'', an attempt to reboot ''Kinniku Banzuke'' in Furutachi's absence. Its debut season would heavily feature ''Sasuke'' content in the form of qualification rounds for ''Sasuke 13''. ''Golden Muscle'' would prove to be a failure, due to lower budget, the lack of experience in Dreamax, and struggling to attract the same athletes as past series.

In Summer of 2004, Masato Inui left Dreamax following production disputes and frustrations with the series, forming his own production studio FOLCOM alongside several other producers from ''Kinniku Banzuke''. Production stalls led to ''Sasuke 14'' being delayed until January 2005. Following this tournament, Ushio Higuchi would too decide to leave Dreamax and begin his own production company, Monster9.

2005–2011: Monster9, American qualifiers and cancellation

Shortly after founding Monster9, Higuchi announced his newest Survival Attack spinoff, '' Viking'', which was to film immediately and air on competing network FujiTV. Viking featured the same general format as ''Sasuke'', but brought in aspects of other ''Kinniku Banzuke'' events such as ''Ottoto 9'', ''Amazing Road'', ''Body Clock'' and ''Brain Panic''. Within days of announcing ''Viking'', TBS filed for ownership of the ''Sasuke'' brand, and further press releases regarding ''Viking'' were modified to remove reference to Survival Attack or ''Sasuke'' by name. This led to confusion regarding the series, giving many of the same competitors appeared on ''Viking'', and at the time believed they were directly related.

Following the release of ''Viking'', TBS and Higuchi were able to come to an agreement where Higuchi would continue to produce ''Sasuke'', ''Kunoichi'' and ''Sportsman No. 1'' as a contractor for TBS. Production on ''Sasuke'' resumed, with the 15th tournament broadcasting in July 2005, and resumed its Spring and Fall schedule in 2006. In ''Sasuke 17'', fisherman Makoto Nagano became only the second person to complete the ''Sasuke'' course, prompting a widespread reimaging of ''Sasuke''. At the same time, Higuchi had be fired from FujiTV for mismanagement of ''Viking'' at the end of 2006. As a result, ''Sasuke 18'' boasted the most extensive renewal that has ever occurred in a Ninja Warrior series, utilizing the fabricated course components from both ''Sasuke'' and ''Viking'' to replace or modify nearly every single obstacle on the entire course. This tournament introduced the Salmon Ladder, which would become a staple for Ninja Warrior series worldwide.

Overseas, NBCUniversal's niche gaming network G4 licensed '' Kinniku Banzuke'', ''Sasuke'' and '' Kunoichi'' from TBS, where they created their own subtitled edits of the series under the titles ''Ninja Warrior'', ''Unbeatable Banzuke'' and ''Women of Ninja Warrior''. The show proved to be quite popular with the small network, and so G4 pursued a closer partnership with Higuchi and TBS. In Summer 2007, G4 launched '' American Ninja Challenge'', a reality show where contestants could audition and take part in a series of challenges to win a spot in ''Sasuke 19''. Two competitors went to Japan, however ''Sasuke 19'' proved to be the most lethal in the show's history, with only two 1st Stage clears, who both went on to fail at the Salmon Ladder. ''American Ninja Challenge'' returned for a second season in 2008, where Levi Meeuwenburg shocked Japanese audiences after being the only competitor to clear the 2nd Stage, earning him the title of Last Man Standing. The co-operation between ''American Ninja Challenge'' and ''Sasuke'' continued for two additional seasons, before interest in America grew high enough that NBC decided to ramp up production. 2009 saw the debut season of '' American Ninja Warrior'', where hundreds of competitors competed shorter preliminary stages to win one of ten spots in ''Sasuke 23''. The show saw continued interest, with the 2nd and 3rd seasons sending competitors to ''Sasuke 26'' and ''Sasuke 27''. In Japan, breakout star Yuji Urushihara became the third to achieve Total Victory, and then the first to achieve Total Victory twice only three seasons later.

In November 2011, Ushio Higuchi's Monster9 filed for bankruptcy as a result of financial mismanagement, legal disputes and settlements with stage acrobat group Muscle Musical and plummeting viewership. As a result, ''Sasuke'', ''Kunoichi'' and ''Sportsman No. 1'' all went into hiatus during legal proceedings, and were subsequently cancelled by TBS. As a result of this cancellation, NBC made the decision that for the first time ever, they would host their own full scale tournament in Las Vegas, and as a result ''American Ninja Warrior''s fourth season saw 100 competitors complete a course in the US, with Japan cut out of the format. Due to the higher production costs, NBC decided to move the program from G4 to attract higher viewership. This new format was a massive success, however G4 would shut down within 6 months of this change, resulting in an end to Japanese ''Sasuke'' broadcasts in the United States.

2012–2015: reboot, international expansion and spinoffs

Following the end of the Monster9 legal proceedings in July 2012, TBS made the decision to reboot ''Sasuke'' and ''Sportsman No. 1''. ''Sasuke'' would be renamed ''Sasuke Rising'' and would be produced by FOLCOM, with former assistant producer and series creator Masato Inui returning to helm the show alongside Dreamax Television. ''Sportsman No. 1'' would be handled by other TBS departments are renamed to ''Sports Danshi Grand Prix'', due to a ownership dispute over the trademark with Ushio Higuchi.

Behind the scenes, the success of ''American Ninja Warrior'' led TBS to believe they could market the series to a much wider audience, and the idea of the ASEAN Open Cup was conceived. ''Sasuke'' would expand into ASEAN countries which would feature shorter courses and special events, which would then act as qualifiers for ''Sasuke''. The project was piloted with the launch of ''Sasuke Singapore'' and ''Sasuke Malaysia'' in 2012, sporting half length 1st Stage courses followed by the Final Stage tower. In Japan, rules were adjusted to allow competitors on ''Sasuke'' to qualify for the ASEAN Open. ''Sasuke 29'' featured the first major rule changes in series history, with the 3rd Stage's maximum rest time being removed. ''Sasuke 30'' restored this, instead added an additional knockout stage between the 2nd and 3rd Stage which would appear if there were more than ten 2nd Stage clears, however this went unused. After two seasons of each, the first ASEAN Open Cup was held in Malaysia featuring teams from ASEAN regions, Japan and the United States. Following this event, interest died off, and the ASEAN Open Cup was discontinued as a failure.

In 2015, Yusuke Morimoto became the fourth person to achieve Total Victory, shortly followed by Geoff Britten and Isaac Caldiero, who became the first two competitors outside of Japan to achieve total victory in ''American Ninja Warrior''s seventh season. Following ''Sasuke 31'', FOLCOM took over full control of the production of ''Sasuke''. Globally, despite the previous failure to expand into ASEAN countries, 2015 saw massive expansion through Europe and Asia, with localized versions being produced in China, Denmark, Indonesia, Sweden, Turkey, the United Kingdom and Vietnam. This trend continued with France, Germany and Italy in 2016; Austria, Australia, Egypt, Hungary, Netherlands, Russia and Spain in 2017; and Israel, Romania and Switzerland in 2018. 2017 additionally saw a full reboot of Kunoichi, featuring redisgned courses more akin to Sasuke.

In the United States, NBC decided to expand the portfolio of the series by creating several spinoffs. The international crossover series '' American Ninja Warrior: USA vs. The World'' featured top competitors from each international version competing in a head to head competition. '' Team Ninja Warrior'' saw teams of three racing against other members for the fastest times. '' American Ninja Warrior Junior'' featured kids racing each other for the fastest times. These formats proved popular and saw their own international adaptations in China, Denmark, France, Germany, Israel and Vietnam.

In Japan, Ushio Higuchi had created a new company called GoldEggs following the dissolution of Monster9, and in 2017 attempted to launch his own unlicensed successor to ''Viking'' called ''KuroOvi: The Ultimate Hero''. He would once again use ''Sasuke'' and ''Kinniku Banzuke'' content in an attempt to promote his series, as well as featuring many competitors from ''Sasuke'', ''Viking'', and ''Kunoichi''. The series would also feature simultaneously released English dubs. The series was a financial failure, with the English broadcast being cancelled after only one month due to an average viewership of under 150 views per episode.

2019 saw new versions licensed in Mongolia and Poland, which to date are the most recently produced new adaptations of ''Ninja Warrior''.

2019–present: format variations, COVID-19 and IOC certification

By 2019, more than 60% of the international adaptations that had been produced had already ended, with the high costs of production compared to viewership being a primary factor. The situation worsened significantly followed the outbreak of the COVID-19 pandemic, when production was suspended globally on large scale TV series. ''American Ninja Warrior''s 12th season featured modified rules and courses to distance competitors, while the remaining global seasons were postponed until late 2020 or into 2021. The change in market and year away from broadcasting significantly impacted viewership, with returning series seeing greatly reduced ratings across the board, leading to many series being cancelled after 2022. Additionally, Israel and Russia's productions ceased due to the 2022 Ukraine invasion and 2022 Gaza–Israel clashes. By mid 2023, Japan, the United States, France, Germany and Poland were the only countries with series in active production.

In order to regain interest in the series, many adaptations began introducing changes to the format. American Ninja Warrior introduced twists such as the Safety Pass, Speed Pass, Power Tower and side by side racing – all changes that would be seen extensively abroad in the 2020s. ''Sasuke'' would remain the only series that remained true to the roots of the series.

Following the failure of ''KuroOvi'', GoldEggs sought to create a chain of ninja gyms across Japan titled Ninja Park, which would additionally host in-person competitions under the banner ''Ninjathlon''. As part of this process, GoldEggs would file trademark ownership claims over several iconic ''Sasuke'' obstacles in both Japan and the United States. While unsuccessful in the US, Higuchi and GoldEggs were able to successfully claim six obstacles in Japan. As a result, beginning in ''Sasuke 40'', several obstacles were renamed to avoid legal injunctions, most notably with the Spider Walk being renamed to Spider Run, and Cliffhanger Dimension being renamed to Cliff Dimension.

Following the conclusion of the 2020 Summer Olympics in 2021, the Union Internationale de Pentathlon Moderne (UIPM) voted to remove Equestrian from the Modern Pentathlon following concerns of Animal rights. Due to extremely low viewership, the UIPM aimed to bring in a new discipline that would make the event more appealing to viewers. Following several rounds of testing and votes, the UIPM voted to add obstacle racing to the modern pentathlon beginning with the 2028 Summer Olympics. The course would be standardized and obstacles would be licensed directly from ''Sasuke'' and TBS, finally fulfilling Ushio Higuchi's initial dream of creating a new sport after 35 years. Conversely, ''Sasuke 39'' debuted a new final stage featuring a Speed climbing zone, with a layout variant of the normal standard.

Due to Japan's success in winning 3 Gold, 1 Silver and 1 Bronze in Skateboarding during its debut at the 2020 Summer Olympics, TBS launched ''Kasso'' four months prior to the 2024 Summer Olympics to build up hype for the event. ''Kasso'' is an official spinoff that fuses ''Sasuke''s format with skateboarding in the style of ''Skeboarder'' from '' Kinniku Banzuke''. While the show was a failure in Japan and was cancelled shortly after broadcast, the first tournament netted an unexpected 6 million views internationally within one year, prompting the immediate revival and international licensing of the series by TBS.

Following this announcement, TBS would invest heavily into the ''Sasuke'' brand. In 2024, TBS broadcast the first ever ''Sasuke World Cup'' shortly after the 2024 Summer Olympics, featuring a total of 35 top ninja competitors from Australia, France, Germany, Japan and the United States. TBS continued their lineup by rebooting ''Kunoichi'' and ''Sasuke Junior'' in January 2025, and debuting a new spinoff format called ''Hanzo'' in March 2025 that brought in elements of Swimming, Shooting, Fencing and Running to align the format more closely with the Modern Pentathlon. ''American Ninja Warrior'' and ''Ninja Warrior Poland'' would both alter the formats of their 2025 seasons to feature side-by-side racing brackets similar to the IOC standard instead of the original Survival Attack format.

Abroad, renewed interest in the series began with discussions occurring to expand the franchise into Latin America, Cambodia and Thailand, although as of 2025, filming has not begun on these new series.

Format

An initial group of competitors are recruited to compete, originally consisting of competitor who excelled on Kinniku Banzuke such as Katsumi Yamada, Tomohiro Tatsukawa and Akira Omori, and in later seasons by reinviting competitors who have done well on Sasuke, and occasionally its international adaptations.

The remaining spots are filled by applications who could submit videos, originally via VHS, and later through DVD and the internet. Shortlisted applicants are interviewed with a group selected based on a combination of physical skills, personality and passion. In some seasons, the remainder is then filled by having hopefuls compete in preliminary trial rounds. These can vary from ''Sasuke'' courses, to Boot camp style tasks, to a marathon, or a combination of the above.

Course structure

''Sasuke'' consists of four stages of increasing difficulty; competitors must complete each stage to advance to the next. Each competition is taped one to nine weeks prior to broadcast, where it is edited down to show only a handful of runs that are deemed either interesting, or featured a notable competitor. In ''Sasuke 36'' and ''Sasuke 37'', only the 1st through 3rd stages were recorded in advance, with the Final Stage broadcasting live from Yokohama Red Brick Warehouse.

The object is to hit the buzzer at the end of each course before the allotted time expires. If a competitor goes out of bounds, runs out of time or comes into contact with the water in any of the pits below the course, they are disqualified from the competition.

First stage

The First Stage primarily tests one's general athletic abilities, with a focus on balance, agility, and speed. One average, approximately 81% of competitors are eliminated on the 1st Stage. However, in the 4th competition, a record 37 of the original 100 competitors made it past the First Stage. After each full course completion, the First Stage was thoroughly redesigned to be much more difficult and prevent large numbers of people from moving on. In the 19th competition, only two competitors cleared the First Stage (neither of the two being ''Sasuke'' All-Stars), a record in ''Sasuke'' history.

While obstacles change from season to season, the course always general features the following structure, both on Sasuke and abroad:

* An opening segment featuring a "step" obstacle such as the Quadruple Steps, a "sliding" obstacle such as the Log Grip and a balance obstacle.
* Since ''Sasuke 5'', the Warped Wall or a variation of it
* From ''Sasuke 1'' through ''Sasuke 34'', a final climb, although it could be argued that the Warped Wall since ''Sasuke 35'' meets these criteria.

Second stage

Those with enough skill to complete Stage One then take on an even more grueling set of obstacles in Stage Two. The obstacles determine the time limit, and it is usually between 50 and 100 seconds.

Unlike the First Stage, which has always required the competitors to hit a buzzer at the end of the course to stop the clock and pass the course, the Second Stage did not have a buzzer at its end until the 8th competition. Before then, the competitors simply walked through an open gate to stop the clock. From the 8th competition onward, the buzzer opens the gate. If the competitor breaks the gate open without hitting the button, they are disqualified. In addition, the course judges can hold the gates closed if a competitor committed a foul earlier in the Second Stage that would result in their disqualification, such as using the Chain Reaction gloves on the Spider Walk as Katsumi Yamada had done in the 12th competition.

On average, 19% of competitors attempt the Second Stage on each competition, with an average of 41% of attempts clearing. In the 19th competition, neither of the two qualified competitors cleared the 2nd Stage, marking the earliest end of a ''Sasuke'' competition.

While obstacles change from season to season, the course always general features the following structure, both on Sasuke and abroad:

* Since ''Sasuke 7'', the first obstacle has been a "sliding" obstacle, such as Chain Reaction.
* In ''Sasuke 14'' through ''Sasuke 30'', an upper body balance obstacle such as Metal Spin or Unstable Bridge has been present mid-stage.
* Since ''Sasuke 18'', the Salmon Ladder has been present as the 2nd obstacle, place before either the balance obstacle, or Spider Walk.
* The 2nd Stage has ended with Wall Lift, or a variation of it, in every tournament besides ''Sasuke 18''.

Third stage

The Third Stage has no overall time limit unlike the other stages, however there is a resting time limit that species the maximum amount of time a competitor may wait between obstacles. This varies between 30 and 120 seconds depending on the season, with the only exception being ''Sasuke 29'', which was truly untimed. In each rest area, competitors can apply "sticky spray" to improve their grip. While the first two stages focus on speed and agility, this course almost exclusively tests one's upper body strength and stamina.

An average of 8% of competitors will attempt, with approximately 17% of attempts succeeding. The record for most Third Stage clears in a tournament is five, achieved in the 3rd and 24th tournaments.

While obstacles change from season to season, the course always general features the following structure, both on ''Sasuke'' and abroad:

* An opening obstacle with a very low fail rate that exists only to burn stamina, such as Propeller Bars, Rumbling Dice and Drum Hopper.
* Since ''Sasuke 9'', An obstacle that features grip based transfers between stationary objects, such as Lamp Grasper, Devil Steps, Floating Boards and Sidewinder.
* Since ''Sasuke 4'', Cliffhanger, or one of its variants (like the crazy clifthanger).
* Since ''Sasuke 18'', a harder grip area, such as Spider Flip, Hang Climb, or Vertical Limit.
* A final dismount from a ring or bar, such as Pipe Slider or Flying Bar.

Final stage

Unlike other stages, the Final Stage is only adjusted following a win or near-miss event. To date, the Final Stage has known seven forms. Each of these share a single, common goal: reach and hit the button at the top of a tower before time expires. Reaching the top is referred to as ''kanzenseiha'' (), translated roughly as "complete domination", literally as "complete victory", and rendered on ''Ninja Warrior'' as "total victory". The Final Stage's time limit is between 30 and 45 seconds.

Version 1 (1997–1999)

The original Final Stage was a 15 meter (49 foot) Rope Climb with a 30 second time limit. This version was completed by Kazuhiko Akiyama after eleven previous failed attempts by other competitors.

Version 2 (2000–2006)

The total height was increased to 22.5 meters (74 feet), with the bottom 12.5 meters (41 feet) being Spider Climb, and the upper 10 meters (33 feet) being a Rope Climb. This version was defeated by Makoto Nagano on his fourth attempt, with six other failed attempts by others.

Version 3 (2007–2010)

In this version, the Spider Climb section was replaced with a ladder, and a time limit of 45 seconds. The original variant sported a 12.5 meter (41 foot) metal ladder, which was later increased to 13 meters (43 feet), however neither of these variants were attempted. The third revision replaced the metal ladder with a 13 meter (43 foot) rope ladder. This third version was attempted only once by Yuuji Urushihara, who was milliseconds away from completing it on its first attempt. As a result, a fourth revision was debuted in ''Sasuke 23'' which featured the same layout, but a lower time limit of 40 seconds. This version would be defeated by Yuuji Urushihara on his second attempt, with six others failing to complete it, including previous winner Makoto Nagano.

Version 4 (2010–2011)

The original fourth version of the Final Stage returned to being only a rope climb, however this time being 23 meters (75 feet) with a time limit of 40 seconds. That version went unchallenged, with a second revision appearing in ''Sasuke 27'' which had a reduced height of 20 meters (66 feet). This version was defeated by Yuuji Urushihara, with only one other failed attempt.

Version 5 (2012–2015)

The debut of the fifth version of the Final Stage originally saw the 23 meter (75 foot) rope return, however this was changed in ''Sasuke 29'' to feature a taller implementation of Version 2, with 12 meters (39 feet) of both Sider Climb and Rope Climb in 30 seconds. This version was defeated by Yusuke Morimoto after two other failed.

Version 6 (2016–2020)

This new version of the Final Stage featured 8 meters (26 feet) of Spider Climb, followed by the debut of a 7 meter (23 foot) Salmon Ladder, and ending with a 10 meter (33 foot) Rope Climb in 45 seconds. The Salmon Ladder originally contained 19 jumps, however this was reduced to 15 after one tournament to increase the difficulty with larger gaps. This version was defeated by Yusuke Morimoto on his third attempt, with Tatsuya Tada and René Casselly also failing.

Version 7 (2021–)

The current version of the Final Stage replaced the Spider Climb with a custom 8.5 meter (28 foot) variant of the IFSC standard Speed Climbing wall, 57% the height of the normal speed climbing standard. To date, this final has been attempted four times in competition, and twice in the ''Sasuke World Cup'', however it has gone undefeated.

Notable competitors

Sasuke All-Stars

The Sasuke All-Stars were a group of six favored competitors, established by the TBS network, originally thought to be the most likely to clear all four stages. Consisting of Shingo Yamamoto, Katsumi Yamada, Kazuhiko Akiyama, Toshihiro Takeda, Makoto Nagano and Bunpei Shiratori, they comprised a large portion of the competitors' success in the first decade of ''Sasuke''. The first two champions, Akiyama and Nagano, are also included, as is the only competitor to compete in every tournament, Yamamoto.

The All-Stars were officially 'retired' in the 28th tournament, but this decision was reversed. Shingo Yamamoto continued to compete in Sasuke 29 and onwards. Takeda retired in ''Sasuke'' 38, Shiratori retired in ''Sasuke'' 30 but returned in the 42nd tournament, Nagano retired in ''Sasuke'' 32, but has since made appearances in the 38th, 40th, 41st and 42nd tournaments. Akiyama retired in ''Sasuke'' 28, but returned in the 40th tournament, and Yamada has competed in all tournaments since ''Sasuke'' 33.

Sasuke New Stars

The Sasuke New Stars (''Shin Sedai'') are younger competitors who made a name for themselves during the Shin-Sasuke era. "Shin Sedai" or New Stars became famous since ''Sasuke'' 17, after Shunsuke Nagasaki made it to the Final Stage. There was a brief hiatus before the term was re-popularized in ''Sasuke'' 22 when Yuuji and Kanno made it to the Third Stage. Membership in the Shin Sedai has been more fluid than the All-Stars, with Shunsuke Nagasaki, Yuuji Urushihara, Hitoshi Kanno, Koji Hashimoto, Jun Sato, Ryo Matachi, Kazuma Asa, Yusuke Morimoto, Tomohiro Kawaguchi, Shinya Kishimoto, Masashi Hioki and Yusuke Suzuki all having been considered members at certain points.

Morimoto Stars

The Morimoto Stars (''Morimoto Sedai'') is an informal term for the group of competitors who emerged post-Yusuke Morimoto's first ''kanzenseiha'' and are now some of the most consistently strong competitors. The members are usually considered to be Yusuke Morimoto, Tatsuya Tada, Keitaro Yamamoto, Jun Sato and Naoyuki Araki.

Winners around the world

Below is a complete list of competitors to achieve Total Victory. Winners are assumed to be of the nationality of their respective show unless otherwise marked. When a season has multiple winners, order is determined by the order shown during broadcast. All results are taken from their respective television broadcasts. Total Victory is achieved only when a competitor completes all stages of the original tournament format of a Ninja Warrior course. Any series with a guaranteed winner is not considered eligible for this title.

Total victories during regular seasons

As of 2025, there have been a total of 34 Total Victories achieved by 29 individuals.

Of wins to date, the United States has had 7, Japan and France have each had 6, Israel has had 4, Vietnam and Australia have had 3, and Germany has had 2.

To date, David Campbell and Joel Mattli are the only two competitors to achieve Total Victory outside their home country.

Other notable results

Women's finals buzzers

Throughout Ninja Warrior history, it is relatively uncommon for women to hit buzzers due to the relative advantage men have in mixed-gender sports. There have been over 100 buzzers by women during qualifiers and 40 during semifinals, buzzers on the finals course are still quite rare. Buzzers marked as EX indicate a buzzer on a finals course that occurred during a special outside of a main season, which had removed or modified the time limits.

There have been a total of 43 finals buzzers by 17 women. Of these, Jessie Graff and Olivia Vivian have each hit 8, Steffanie Edelmann and Jesse Labreck have hit 5, Addy Herman has hit 3, and Isabella Folsom has hit 2.

This run would have cleared in the corresponding regular season this special aired in
