and reorganized the party. The Labour-Farmer Party was reconstituted, with opposition from the Comintern-affiliated communists, into the Proletarian Masses Party with Mosaburō Suzuki as Secretary General. Masanosuke Watanabe, the chair of the party, committed suicide on 6 October 1928, after being arrested. An attempt to reform Hyōgikai resulted in more arrests, so a new organization, the National Council of Japanese Labor Unions (Zenkyō), was formed as an underground group with 5,500 members on 25 December. Police found a chart of the JCP's district organization in Tokyo after arresting a prominent member on 18 March 1929. Shoichi Ichikawa was arrested on 28 April, Mitamura Shiro and Nabeyama Sadachika on 28 April, and Manabu Sano avoided arrest until his apprehension in Shanghai on 16 June 1929. Kenzo Yamamoto, who was sick in Moscow, was one of the few leaders not imprisoned. 81 high-ranking members of Zenkyō were arrested in April. The party was reconstituted by Seigen Tanaka, Zenshirō Zennō, and Sano Hiroshi in July. Many members wanted to dissolve the party as the Peace Preservation Law was amended to inflict the death penalty. A police raid led by a former wrestler arrested most of Seigen Tanaka's subordinates on 14 July 1930, and he was arrested later that same day. Kenzō Yamamoto was executed by the Soviets in 1939, after Sanzō Nosaka accused him of spying; Yamamoto's death was reported as 1942, and the truth about his death was not revealed until 1992.

A new document supported by the Comintern, the 1932 Draft Thesis, was written by Nosaka and served as the JCP's main document until 1946. This document stated that a bourgeois revolution to eliminate feudalism and the emperor must occur before the proletariat revolution. Kazama and other leaders were arrested in fall 1932. The party was reformed by Masami Yamamoto, who was also sent from Moscow, in January 1933, but he was arrested on 3 May.

, the JCP, unlike the French, and Italian communists, emerged into the postwar period without an organizational base established through wartime resistance movements. As a result, the postwar JCP relied heavily on support of Korean activists in Japan. Of the roughly one thousand supporters who gathered in Western Tokyo to greet party members who had emerged from prison on 10 October 1945, half or more were Korean. Initially the JCP advocated for a united front with the Japan Socialist Party though this did not occur due to profound positional disagreements between the two parties. Nosaka returned to Japan after fourteen years in exile on 10 January 1946. Under the guidance of Nosaka, the party pursued a policy of portraying itself as "lovable". Nosaka's strategy involved avoiding open calls for violent revolution and taking advantage of the seemingly pro-labor stance of the Allied occupation to organize the urban working classes and win power at the ballot box and through propaganda. In particular, the party was successful in winning acceptance of the notion that communists had been the only ones to resist Japanese wartime militarism. This propaganda effort won the party thousands of new members and an even larger number of sympathizers, especially among artists and intellectuals. Party membership, which never exceeded 1,000 in the pre-war period, rose from 1,180 in December 1945, to 7,500 by February 1946, 70,000 by December 1947, and over 100,000 by April 1950.

, a union affiliated with the JCP, had around 1.5 million members as overall Japanese union membership rose to 6 million in the post-war period. The JCP benefited from Japan's Korean population that was more favorable to communism due to discrimination and high unemployment rates. The JCP made dramatic gains in the 1949 general election, tripling its popular vote support and increasing its seat total from 4 to 35.

This devastating "Cominform Criticism" led rival JCP factions to compete for the Cominform's approval, and ultimately led to the militant which declared that "it would be a serious mistake to think that Japan's liberation can be achieved through peaceful, democratic means" and called for an immediate violent revolution. This thesis was a combination of late Stalinist and Maoist thought. The result was a campaign of violence in which JCP activists threw Molotov cocktails at police boxes and cadres were sent up into the mountains with instructions to organize ostensibly oppressed farmers into " mountain guerrilla squads". The backlash to the JCP's new militant line was swift and severe. Militants were rounded up, tried, and sentenced to lengthy prison terms, and in the 1952 general election, Japanese voters vented their ire at the JCP by stripping the party of every single one of its 35 Diet seats, a blow from which it would take two decades to recover. Stunned, the JCP gradually began to pull back from its militant line, a process facilitated by the death of Stalin in 1953. At the 6th Party Congress in 1955, the JCP renounced the militant line completely, returning to its old "peaceful line" of gradually pursuing socialist revolution through peaceful, democratic means. and were informally controlling the JCP in the early 1950s. Tokuda's death in 1953 created a power vacuum in the party. Shida won and Itō was expelled from the party, having been accused of being a spy. Shida's influence waned in the late 1950s as Miyamoto, who became General Secretary in 1958, gained power. Members of Shida's faction later broke away to from a new JCP in September 1965. This group performed poorly in elections despite support from the Soviet Union. In 1959, the party held 11 seats in the prefectural assemblies, 349 seats in the city assemblies, and 565 in the town and village assemblies.


Anpo protests

In 1960, the JCP played a central role in organizing the massive Anpo protests against the U.S.–Japan Security Treaty, which were the largest protests in Japanese history. The JCP took a different line than the

cabinet. The Anpo protests were a turning point in the JCP's ongoing attempts to revive its political fortunes after the disastrous turn toward violent revolution in the early 1950s. Although the Maoists had been purged from the party following the earlier disaster, the JCP was still riven by the age-old rivalry between the Rōnō Ha (Worker-Farmer Faction) and the Kōza Ha (Lecture Faction), which dated back to the prewar era. Among other disagreements, the two factions disagreed over which stage of Marxist development Japan was currently in; the Rōnō Ha believed that Japan had already achieved full capitalism, which meant that an immediate socialist revolution was possible, whereas the Kōza Ha argued that Japan's transition to capitalism was not yet complete and that therefore what was needed was a "two-stage" revolutionfirst a "democratic revolution" that would overthrow American imperialism and establish true democracy, and then a "socialist revolution" that would establish communism.

, favored the Kōza Ha interpretation, as late as the 7th Party Congress in 1958 the "anti-mainstream" Rōnō Ha faction, led by Shōjirō Kasuga, still controlled around 40% of the delegates. The Anpo protests greatly strengthened the hand of the Kōza Ha faction. During the protest, the JCP, still scarred by the backlash to its violent line in the 1950s, consistently advocated peaceful, orderly, and restrained protests. This stance was highly unpopular with the radical student activists of the

student movement. However, the movement proved unpopular with the broader public, and the JCP was able to use its image as a "peaceful" and "positive" force during the protests as a recruitment tool. Membership in the party soared during the course of the protests, doubling from 40,000 to 80,000, and most of the new recruits wound up supporting the Kōza Ha line.


Zenith

Over the remainder of the 1960s, the Kōza Ha was able to purge many members from the Rōnō Ha faction, and others, dissatisfied with JCP policies, quit the party of their own accord. Miyamoto was able to cement his control over the party and reigned as party chairman all the way until 1982. Meanwhile, the party's membership continued to grow rapidly, and the party began to make steady gains at the ballot box, winning more and more seats in the

estimated party membership to be approximately 120,000 (0.2% of the working-age population), Miyamoto reported a membership above 100,000 in 1964, and the party had acquired around 300,000 members by 1970. The JCP's vote totals in the prefectural assemblies doubled between the 1959 and 1963 elections and their seats rose from 12 to 22 despite running 200 fewer candidates. The JCP's vote totals and seats in city council elections rose from 509,069 to 880,991 votes and 218 to 369 seats. Their vote totals in the town council elections doubled and their seats rose from 168 to 314. The JCP's revenue of $9 million in 1969, was larger than all of the other parties except for the LDP. In the 1972 general election, the JCP won an astonishing 38 seats in the Diet, surpassing its 1949 high of 35 and signaling the party's full recovery from the disastrous militant line of the early 1950s. Party membership continued to grow in the 1970s, albeit at a slower rate than in the 1960s, reaching approximately 500,000 members by 1980. By the 1970s the JCP was the largest non-ruling communist party in the world

Central organization

According to the party constitution, the highest body of the JCP is the Party Congress, organized by the Central Committee every 2–3 years, though it may be postponed in special circumstances. Between the congresses, the highest body is the Central Committee, elected by the Party Congress. The Central Committee meets two times every year and can also hold a plenum at the request of one-third of its membership. The Central Committee is made out of regular and alternate members; the latter can participate in Central Committee meetings but cannot vote. The Central Committee also elects the executive committee of the Central Committee, and its chairpersons and vice-chairpersons, the head of the Secretariat.

Press

''Shimbun Akahata'' (Japanese: ''Red Flag Newspaper'') is the daily organ of the JCP in the form of a national newspaper. '' Musansha Shinbun'' (Japanese: ''Proletarian News'') was another publication of the party which was circulated between 1925 and 1929. Several other newspapers preceded and merged into ''Red Flag'', including ''Daini Musansha Shinbun'' (Japanese: ''The Second Proletarian News''), which was merged into ''Red Flag'' in 1932. ''Daini Musansha Shinbun'' was itself the immediate successor to the original ''The Proletarian News'', which was banned by the government in September 1929. ''Daini Musansha Shinbun'' began publication immediately after the ban. In the past, the party published numerous other newspapers as well, including another national paper called ''Nihon Seiji Shinbun'' (Japanese: ''Japan Political News'') and a theoretical journal called ''Zenshin'' (Japanese: ''Forward''). The party also published several regional newspapers such as ''Class War'' in and around

in single-member districts), while the remaining 180 (initially 200) seats are elected by a proportional representation system (votes are cast for party lists in regional multi-member districts, called "blocks" in the House of Representatives). The votes and vote percentages in the table below are the JCP candidates' vote totals for the whole election from before 1993 and just the votes for the party in the election to the 180 proportional seats after 1996. The JCP polled 11.3% of the vote in 2000, 8.2% in 2003, 7.3% in 2005, 7.0% in 2009, and 6.2% in 2012. These results seemed to indicate a trend of declining support, but the party won 21 seats in 2014, up from eight in the previous general election, as the JCP received 7,040,130 votes (13.3%) in the constituency section and 6,062,962 (11.37%) in the party lists.

House of Councillors

Elections to the House of Councillors are staggered. Every three years, half of the House is up for election to six-year terms. In addition, a parallel election system is used: the majority of members of the House of Councillors (currently 146 of 242, or 73 in one regular election to one half of the House) are elected in 45 (formerly 46→47) prefectural districts, votes are cast for individual candidates by SNTV, but with both multi- and single-member districts used and in the latter SNTV becomes identical to FPTP (winner-takes-all). The remaining, currently 96 members (48 per regular election) are elected in one nationwide district. Until 1980, votes there were cast for individuals too by SNTV. Since 1983, votes are cast for party lists and the seats are allocated proportionally (d'Hondt) in the nationwide district. Unlike in general elections to the lower house, a candidate may not be nominated in both segments of one regular election to the upper house. The seats totals show below are the JCP's overall post-election seat totals, not just their seats elected in that particular year. The votes shown are the votes in the election for the 48 (formerly 50) seats in the nationwide SNTV/PR segment.
