Tachi

A is a type of sabre-like traditionally made Japanese sword (''nihonto'') worn by the samurai class of feudal Japan. ''Tachi'' and '' uchigatana'' ("''katana''") generally differ in length, degree of curvature, and how they were worn when sheathed, the latter depending on the location of the , or signature, on the tang. The ''tachi'' style of swords preceded the development of the ''katana'', which was not mentioned by name until near the end of the twelfth century. ''Tachi'' were the mainstream Japanese swords of the Kotō period between 900 and 1596. Even after the Muromachi period (1336–1573), when ''katana'' became the mainstream, ''tachi'' were often worn by high-ranking samurai.

History

The production of swords in Japan is divided into specific time periods:

* (ancient swords, until around 900)
* (old swords, around 900–1596)
* (new swords, 1596–1780)
* (new new swords, 1781–1876)
* (modern or contemporary swords, 1876–present)

The predecessor of the Japanese sword has been called .Kazuhiko Inada (2020), ''Encyclopedia of the Japanese Swords''. p. 33. In the middle of the Heian period (794–1185), samurai improved on the to develop (early Japanese sword). To be more precise, it is thought that the improved the and developed with a hole in the hilt and without decorations on the tip of the hilt, and the samurai developed based on these swords. , which was developed in the first half of the 10th century, has a three-dimensional cross-sectional shape of an elongated pentagonal or hexagonal blade called and a gently curved single-edged blade, typical features of Japanese swords. There is no wooden hilt attached to , and the tang (), integrated with the blade, is directly gripped and used. The term is derived from the fact the central part of tang is hollowed in the shape of ancient Japanese tweezers ().Kazuhiko Inada (2020), ''Encyclopedia of the Japanese Swords''. pp. 32–33.

In the developed after , a structure in which the hilt is fixed to the tang () with a pin called was adopted. As a result, a sword with three basic external elements of Japanese swords, the cross-sectional shape of , a gently curved single-edged blade, and the structure of , was completed.. September 2020. pp.36–37. Its shape may reflect the changing form of warfare in Japan. Cavalry were now the dominant fighting unit, and the older straight were unsuitable for fighting from horseback. The curved sword is a far more efficient weapon wielded by a warrior on horseback; the curve of the blade adds considerably to the downward force of a cutting action. According to historian Karl Friday, before the 13th century, there are no written references or drawings showing swords of any kind were used from horseback. However, According to Yoshikazu Kondo, bow and arrows were certainly the main weapons used in cavalry battles, but from around the Genpei War in the 12th century, the use of on horseback increased. Early models had uneven curves with the deepest part of the curve at the hilt. As eras changed, the center of the curve tended to move up the blade.. September 2020. pp. 6, 36–37.

By the 11th century during the Heian period, were exported to neighboring countries in Asia. For example, in the poem "The Song of Japanese Swords" Ouyang Xiu, a statesman of the Song dynasty in China, described Japanese swords as follows: "It is a treasured sword with a scabbard made of fragrant wood covered with fish skin, decorated with brass and copper, and capable of exorcising evil spirits. It is imported at a great cost."Takeo Tanaka (2012). . p. 104. Kodansha.

From the Heian period (794–1185), ordinary samurai wore swords of the style called (, ), which meant black lacquer . The hilt of a is wrapped in leather or ray skin, and it is wrapped with black thread or leather cord, and the scabbard is coated with black lacquer. On the other hand, court nobles wore decorated with precisely carved metal and jewels for ceremonial purposes. High-ranking court nobles wore swords of the style called or (), which meant decorative , and lower-ranking court nobles wore simplified swords of the style called , which meant thin . The and worn by nobles were initially straight like a , but since the Kamakura period they have had a gentle curve under the influence of . Since worn by court nobles were for ceremonial use, they generally had an iron plate instead of a blade.Kazuhiko Inada (2020). ''Encyclopedia of the Japanese Swords''. pp.36–44. . September 2020. pp. 37–41.

In the Kamakura period (1185–1333), high-ranking samurai wore (, ), which meant a sword with chains in the arsenal. The scabbard of the was covered with a gilt copper plate and hung by chains at the waist. At the end of the Kamakura period, simplified came to be made as an offering to the of Shinto shrines and fell out of use as weapons. On the other hand, in the Kamakura period, there was a type of called () with a scabbard covered with metal, which was used as a weapon until the Muromachi period. The meaning was a sword wrapped around a leech, and its feature was that a thin metal plate was spirally wrapped around the scabbard, so it was both sturdy and decorative, and chains were not used to hang the scabbard around the waist.

The Mongol invasions of Japan in the 13th century during the Kamakura period facilitated a change in the designs of Japanese swords. The swordsmiths of the Sōshū school represented by Masamune studied ruined – broken or bent in battle – to develop new production methods, and create innovative swords. They forged the blade using a combination of soft and hard steel to optimize the temperature and timing of the heating and cooling of the blade, resulting in a lighter and very robust blade. They also made the curve of the blade gentle, lengthened the tip linearly, widened the width from the cutting edge to the opposite side of the blade, and thinned the cross section to improve the penetration and cutting ability of the blade.

Historically in Japan, the ideal blade of a Japanese sword is considered to be the in the Kamakura period, and the swordsmiths from the Edo period to the present day after the period focused on reproducing the blade of a Japanese sword in the Kamakura period. There are more than 100 Japanese swords designated as National Treasures in Japan, of which the of the Kamakura period account for 80% and the account for 70%.. ''Touken World''.. Sankei Shimbun.

The was stronger than the because its hilt was wrapped in leather or ray skin, lacquer was painted on top of it, leather straps and cords were wrapped around it, and the scabbard and sometimes the (hand guard) were also wrapped in leather.

By the 15th century, Japanese swords, including , had already gained international fame by being exported to China and Korea.Takeo Tanaka (1982) . p. 348. Shibunkaku. For example, Koreans learned how to make Japanese swords by sending swordsmiths to Japan and inviting Japanese swordsmiths to Korea. According to the record of June 1, 1430, in the ''Veritable Records of the Joseon Dynasty'', a Korean swordsmith who went to Japan and mastered the method of making Japanese swords presented a Japanese sword to the King of Korea and was rewarded for the excellent work which was no different from the swords made by the Japanese.

Traditionally, (bows) were the main weapon of war in Japan, and and were for close combat. The Ōnin War in the late 15th century in the Muromachi period expanded into a large-scale domestic war, in which employed farmers called were mobilized in large numbers. They fought on foot using shorter than . In the Sengoku period (period of warring states) in the late Muromachi period, the war became bigger; fought in a close formation using (spears) lent to them. Furthermore, in the late 16th century, (matchlock arquebuses) were introduced from Portugal, and Japanese swordsmiths mass-produced improved products, with fighting with leased guns. On the battlefield in Japan, guns and spears became main weapons in addition to bows. Due to the changes in fighting styles in these wars, the and became obsolete among samurai, and the , which was easy to carry, became the mainstream. The dazzling-looking gradually became a symbol of the authority of high-ranking samurai.. September 2020. p. 40.

From the 15th century, low-quality swords were mass-produced under the influence of the large-scale war. These swords, along with spears, were lent to recruited farmers called , while swords were exported. Such mass-produced swords are called , and swordsmiths of the Bisen school and Mino school produced them by division of labor.. September 2020. pp. 70–71. The export of Japanese sword reached its height during the Muromachi period—at least 200,000 swords were shipped to Ming dynasty China in official trade in an attempt to soak up the production of Japanese weapons and make it harder for pirates in the area to arm. In the Ming dynasty of China, Japanese swords and their tactics were studied to repel pirates, and and were developed based on Japanese swords.

From this period, the tang () of many old were cut and shortened into . This modification is called . For example, many of the Masamune forged during the Kamakura period were converted into , so his only existing works are and .. Nagoya Japanese Sword Museum Touken World.

In later Japanese feudal history, during the Sengoku and Edo periods, certain high-ranking warriors of the ruling class wore their sword -style (edge-downward), rather than with the scabbard thrust through the belt with the edge upward. This style of swords is called , "half ". In , styles were often mixed, for example, fastening to the was style, but metalworking of the scabbard was style.

With the rise of statism in Shōwa Japan, the Imperial Japanese Army and the Imperial Japanese Navy implemented swords called , worn style (cutting-edge down).

In the Shintō period from around 1596 in the Azuchi–Momoyama period, the traditional techniques of the Kotō period were lost, and no smith was able to reproduce the of the Kamakura period. However, in 2014, Kunihira Kawachi succeeded in reproducing a from the Kamakura period. He received the Masamune Prize, the highest honor as a swordsmith. On the he forged, (a pattern of hazy white shadows between and ), characteristic of the Bizen school in the Kamakura period.
