The Japanese Communist Party (日本共産党, Nihon Kyōsan-tō, abbr. JCP) is a communist party in Japan. Founded in 1922, it is the oldest political party in the country. It has 250,000 members as of January 2024, making it one of the largest non-governing communist parties in the world. The party is chaired by Tomoko Tamura, who replaced longtime leader Kazuo Shii in January 2024.
The JCP was repressed by the Japanese government in the three decades immediately following its founding. The Allied occupation of Japan legalized the JCP after World War II, but the party's unexpected success in the 1949 general election led to the "Red Purge", in which the Japanese government removed tens of thousands of actual and suspected communists from their jobs. The Soviet Union encouraged the JCP to respond with a violent revolution; the consequent internal debate fractured the party into several factions. The dominant faction, backed by the Soviets, waged an unsuccessful guerrilla campaign in Japan's rural areas, which undercut the party's public support.
In 1958, Kenji Miyamoto became the JCP's leader and moderated the party's policies, abandoning the previous line of violent revolution. Miyamoto also began distancing the JCP from the Eastern Bloc in the 1960s. The party maintained a neutral stance during the Sino-Soviet split, declared its support for multi-party democracy in opposition to the one-party politics of China and the Soviet Union, and purged pro-Soviet or Chinese members. His efforts to regain electoral support were particularly successful in urban areas such as Osaka, Kyoto, and Tokyo, and the JCP worked with the Japan Socialist Party (JSP) in the 1970s to elect a number of progressive mayors and governors. By 1979, the JCP held about 10% of the seats in the National Diet. The party saw a brief electoral resurgence after the collapse of the JSP in 1996; however, the party has generally been in decline since in terms of electoral results and party membership.
The party at present advocates the establishment of a democratic society based on pacificism. It believes that this objective can be achieved by working within an electoral framework while carrying out an extra-parliamentary struggle against "imperialism and its subordinate ally, monopoly capital". As such, the JCP does not advocate violent revolution but rather a "democratic revolution" to achieve "democratic change in politics and the economy". It accepts the current constitutional position of the emperor but opposes the involvement of the Imperial House in politics. A staunchly anti-militarist party, the JCP firmly supports Article 9 of the Japanese Constitution and seeks to dissolve the Japan Self-Defense Forces. It opposes Japan's military alliance with the United States as an unequal relationship and infringement of Japan's national sovereignty.




History






= Foundation

=
Sanzō Nosaka became a communist in the late 1910s and was a founding member of the Communist Party of Great Britain. Sen Katayama left Japan for the United States in 1914, after serving a prison sentence for supporting a strike. He became a communist during his time in the country and was a founding member of the Communist Party USA. Katayama founded the Association of Japanese Socialists in America and served as chair of the Far Eastern People's Congress.
In 1921, Katayama was informed by the Communist International (Comintern) that the First Congress of the Toiler of the Far East would be held on 21 January 1922 in Irkutsk. Three men from his organization (Watanabe Haruo, Taguchi Unzo, and Maniwa Suekichi) served as delegates. The Japanese Communist Party was founded in Tokyo on 15 July 1922, at a meeting where Kyuichi Tokuda discussed sessions held between the Japanese delegation and Comintern officials. Two delegates were sent to the 4th World Congress of the Communist International and a general meeting of the party was held in Ichikawa, Chiba, on 4 February 1923.
The party's early leadership was drawn from the anarcho-syndicalist and Christian socialist movements that developed around the turn of the century. From the former came Yamakawa Hitoshi, Sakai Toshihiko, and Kanson Arahata, who had all been supporters of Kōtoku Shūsui, an anarchist executed in 1911. Katayama, another early party leader, had been a Christian socialist for much of his political life. The three former anarchists were reluctant to found the JCP, with Yamakawa shortly after arguing that Japan was not ready for a communist party and calling for work to be done solely within labor unions. Katayama's theoretical understanding of Marxism also remained low. In the aftermath of the 1923 Great Kanto Earthquake, there was a campaign of rumors instigated by Japanese state authorities that incited widespread massacres of suspected enemies of the state by military, police, and vigilante forces. Military and police officials assassinated key leftist leaders under the cover of martial law, including Ōsugi Sakae.




= Outlawed and persecuted

=

In May 1923, a roster of the JCP's membership was found by police at Manabu Sano's quarters at Waseda University. A series of protests were occurring at the university about military training. On 5 June, almost every member of the party, except those in rural areas or outside the country, were arrested. A group of Japanese communists, including Arahata, assembled in Vladivostok in August, and decided to create a proletarian party. Those members arrested in 1923, and released in 1924 believed that the conditions for a communist party were not present and decided to dissolve the party at the Morigasaki Conference in March. However, Grigori Voitinsky rejected this and ordered them to reestablish the party. In August, a committee with Tokuda as chair was formed to reestablish the party. Masanosuke Watanabe and Sano held positions in this committee and Arahata was an organizer in the Kansai region. The JCP was formally reestablished on 4 December 1926. Fukumoto Kazuo, a rising figure in Japanese communism, was a member and his ideology, Fukumotoism, was a main part of the platform.
The JCP was outlawed in 1925 with the passage of the Peace Preservation Law, the JCP was subjected to repression and persecution by the Special Higher Police (Tokkō), nicknamed the "Thought Police". JCP members and sympathizers were imprisoned and pressured to "convert" (tenkō suru) to anti-communist nationalism. Many of those who refused to convert remained imprisoned for the duration of the Pacific War. The Japanese Communist Party member Hotsumi Ozaki, who was part of the Richard Sorge spy ring for the Kremlin, was the only Japanese person hanged for treason under the Peace Preservation Law. Police also widely used methods of torture against arrested communists. One of the JCP members killed by police torture in this period was the writer Kobayashi Takiji.
Hyōgikai was formed on 25 May 1925, and this union served as a vehicle for the communist party. Other proletariat parties (Japan Farmers Party, Japan Labour-Farmer Party, Social Democratic Party, and Labour-Farmer Party) were formed during this period. These parties won seven seats in the 1928 election, but a crackdown on 15 March resulted in 1,200 people, including Communist leaders, being arrested and the Japanese government dissolved Hyōgikai and Labour-Farmer Party. Sano, Watanabe, Shoichi Ichikawa, Kenzō Yamamoto, and Hideo Namba avoided arrest as they were serving as representatives to the 6th World Congress of the Communist International 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. An attempt to reform Hyōgikai resulted in 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 1928.
Police found a chart of the JCP's district organization in Tokyo after arresting a prominent member on 18 March 1929. This resulted in mass arrests that left Yamamoto, who was sick in Moscow, as one of the few leaders not in prison. 81 high-ranking members of Zenkyō were arrested in April. The party was reconstituted by Seigen Tanaka, Zenshirō Zennō, and Hiroshi Sano in July. Many members wanted to dissolve the party as the Peace Preservation Law was amended to inflict the death penalty. Jōkichi Kazama was sent from Moscow to rebuild the party in December 1930. He and Noboru Matsumura wrote the 1931 Draft Thesis, but the Comintern was displeased with it. 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.
In 1932, Japanese authorities raided a meeting of members of the Japanese Communist Party in Atami. According to a March 1933 article on the raid, the accused were not the "rag-tag-and-bobtail" of the people. Only a very small minority of the accused were laborers. Almost all the accused were of the "better classes". Among the accused were two judges, two professors of universities, lawyers, teachers, and students. Professor S.H Roberts of the University of Sydney reported in a 1934 newspaper that "all Japan was stirred when it was realized that only a minority of prisoners were laborers." In addition, the arrested were also accused of being connected to the Omori Bank Robbery.
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 in May. Manabu Sano, Kazama, Tanaka, and other imprisoned Communist leaders denounced communism starting in May. The leadership of the party's central committee passed from Eitaro Noro to Kenji Miyamoto to Hakamada Satomi as a result of each person's arrests. The party lost its organization after Satomi's arrested in 1935.
The JCP campaigned against the invasion of China and the imperial regime's expansionist policy in Asia. Following the outbreak of the 1931 Japanese invasion of Manchuria, the Japanese Communist Party had infiltrated the military, including in Tokyo, and Osaka. They would distribute leaflets, and newspapers opposing the war.




= Postwar reemergence

=
On 4 October 1945, all political prisoners, including communists that had been imprisoned for decades, were ordered to be released by the Allied military occupation of Japan. The first issue of Shimbun Akahata after the end of the war thanked the Allied occupation for the "democratic revolution" that was occurring and called for the recreation of a communist political party. A national conference was held on 8 November 1945, and the 4th Party Congress was held from 1 to 2 December.
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. Sanbetsu, 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.




= Red Purge and turn to violence

=
Beginning in the fall of 1949, in reaction to the JCP's electoral success and as part of the "Reverse Course" in Allied occupation policy amid rising Cold War tensions, the Allied occupation authorities and the Japanese government carried out a sweeping Red Purge, firing tens of thousands of communists and suspected communists from government posts, teaching positions at schools, and private corporations. The purge was further intensified in response to the outbreak of the Korean War.

Douglas MacArthur considered banning the JCP on 3 May 1950. Twenty-four members of the party's central committee were removed from office on 6 June and its newspaper, Shimbun Akahata, was suspended on 27 June. A total of 11,000 workers and 1,200 government workers were fired from 1949 to 1950. Union divisions and attacks on communist influence in labor led to Sanbetsu's membership falling to 400,000 by 1949.
Against this backdrop in January 1950, the Soviet-led Cominform, at the behest of Soviet premier Joseph Stalin, issued a blistering criticism of the JCP's peaceful line as "opportunism" and "glorifying American imperialism". It also demanded that the JCP carry out an immediate violent revolution along Maoist lines. This devastating "Cominform Criticism" led rival JCP factions to compete for the Cominform's approval, and ultimately led to the militant "1951 Platform" (51年綱領) 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.
Shigeo Shida and Ritsu Itō 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.




= 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 Japan Socialist Party, Sohyo labor federation, and other groups who argued that the main target of the protest movement was Japanese monopoly capitalism. Instead, the JCP argued that the main enemy was American imperialism, and along with affiliated groups, focused its protests around the U.S. Embassy in Tokyo. Accordingly, JCP-linked groups were the driving force behind the "Hagerty Incident" in which the car carrying U.S. President Eisenhower's press secretary James Hagerty was mobbed outside of Tokyo's Haneda Airport on 10 June 1960, provoking a major international incident and helping to precipitate the downfall of the Nobusuke Kishi 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" revolution—first a "democratic revolution" that would overthrow American imperialism and establish true democracy, and then a "socialist revolution" that would establish communism. Although the "mainstream" of the JCP, led by Kenji Miyamoto, 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 Zengakuren student federation, who broke decisively with the JCP as a result and began to build a New Left 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 National Diet. By the mid-1960s, the United States Department of State 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.
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.




= 1980s to 21st century

=

After the dissolution of the Soviet Union, the JCP released a press statement titled "We welcome the end of a party which embodied the historical evil of great power chauvinism and hegemonism". The party also criticized the Eastern Bloc countries which abandoned socialism, describing their decisions as a "reversal of history". Consequently, the party did not suffer an internal crisis as a result of the Soviet Union's collapse in 1991, nor did it consider disbanding or changing its name. However, owing to a significant loss in electoral support, the party revised its policies in the 1990s and became a more traditional democratic socialist party.
Lam Peng Er argued in the Pacific Affairs in 1996 that "the JCP's viability is crucial to the health of Japanese democracy" because "[i]t is the only established party in parliament that has not been coopted by the conservative parties. It performs the watchdog role against the ruling parties without fear or favor. More importantly, the JCP often offers the only opposition candidate in prefectural governorship, city mayoral and other local elections. Despite the ostensible differences between the non-communist parties at the national level, they often support a joint candidate for governor or mayor so that all parties are assured of being part of the ruling coalition. If the JCP did not offer a candidate, there would be a walkover and Japanese voters would be offered a fait accompli without an electoral avenue of protest. Promoting women candidates in elections to win women's votes is another characteristic of the party. More women are elected under the communist label than other political parties in Japan."
In 2008, foreign media recorded an increase in support for the party due to the effect of the global financial crisis on Japanese workers. However, the party failed to increase its number of seats in the 2009 general election. Subsequently, the projected decline of the party was halted, with the JCP becoming the third-largest party in the Tokyo Metropolitan Assembly and making gains in the House of Councillors, going from six to 11 seats. The party surged in the 2014 elections, receiving 7,040,130 votes (13.3%) in the constituency section and 6,062,962 (11.37%) in the party lists.
During the nomination period of the July 2016 House of Councillors election, the party signed an agreement with the Democratic, Social Democratic and People's Life parties to field a jointly endorsed candidate in each of the 32 districts in which only one seat was contested, uniting in an attempt to take control of the House from the LDP–Komeito coalition. JCP leaders expressed willingness to enter into a coalition with the Democratic Party, a notion which was rejected by then-Democratic Party President Katsuya Okada as being "impossible" in the near future due to what he viewed as some of the "extreme leftist policies" promoted by the JCP. The party had three Councillors up for re-election and fielded a total of 56 candidates in the election, down from 63 candidates in the 2013 election, but still the second-highest number after the LDP. However, only 14 of those candidates contested single- and multi-member districts, while 42 contested the 48-seat national proportional representation block.
Councillor Tomoko Tamura was appointed as the party's first chairwoman on 18 January 2024, replacing Kazuo Shii who had occupied the role for over 23 years.




Ideology and policies


The JCP is one of the largest non-governing communist parties in the world; it is, however, politically moderate and advocates a peaceful transition to communism. Marxism–Leninism, which former party chairman Tetsuzo Fuwa had worked for years to make acceptable to the electorate, was abandoned in favor of scientific socialism in 1976. According to the Encyclopædia Britannica, the JCP became a more traditional democratic socialist party after modifying its policies in the 1990s. This analysis is supported by the Japanese political scientist Kōji Nakakita, who is often cited as a specialist on the JCP. The JCP follows a Marxist ideology, stating that the theory of Marx and Engels is the foundation of their program. The party sits on the left to far-left of the left–right political spectrum.




= Economic policy

=
The JCP strives to change the nation's economic policy of what it views as serving the interests of large corporations and banks to one of "defending the interests of the people". It advocates establishing "democratic rules" that will check the activities of large corporations and "protect the lives and basic rights of the people".
Regarding the international economy, the JCP has advocated establishing a new international democratic economic order on the basis of respect for each country's economic sovereignty. The party strongly opposed Japan's consideration of the failed Trans-Pacific Partnership. The JCP views the United States, transnational corporations, and international financial capital as the main pushers of globalization, which it asserts is negatively affecting the global economy by further widening the North–South economic divide and creating irrevocable environmental problems. The JCP advocates the "democratic regulation of activities by transnational corporations and international financial capital on an international scale".
In September 2015, after the passage of the 2015 Japanese military legislation, the JCP called for cooperation from other opposition parties to form an interim government to abolish the bills. It was the first time the party had called for such cooperation with other parties.




= Social policy

=
The JCP is generally regarded as the most progressive party in Japanese politics. The JCP has traditionally been opposed to the existence of the Imperial House since its inception. However, the party changed its stance in 2004 by acknowledging the Emperor as Japan's head of state. The JCP has stated that it supports the establishment of a democratic republic, but also that "[the monarchy's] continuation or discontinuation should be decided by the will of the majority of the people in future, when the time is ripe to do so". In 2000, the party opposed legislation which reintroduced two symbolic practices to secondary school graduation ceremonies in Japan, namely the raising of the national flag and the singing of the national anthem, both of which the party views as relics of Japan's militarist past.



LGBT rights and feminism

The JCP has been one of the political parties to vocally back LGBTQ+ rights in the country; communist lawmakers have been working to win the passage of same-sex marriage and anti-discrimination laws in parliament. The JCP jointly supports the passing of an LGBT equality law with the Constitutional Democratic Party of Japan (CDP), the Social Democratic Party (SDP), and Reiwa Shinsengumi.
The JCP has maintained a friendly relationship with the Japanese feminist camp since its inception, and is still the most active in women's rights issues among Japan's major political parties. The JCP was the first party to call for universal suffrage for women. The party supports eliminating the wage gap between men and women and has called for the participation of more women in Japanese politics and political life.




= Foreign policy

=
One of the JCP's main objectives is terminating the Japan–United States military alliance and the dismantling of all American military bases in Japan, with a goal to make Japan a non-aligned and neutral country, in accordance with its principles of self-determination and national sovereignty. There are about 130 American military bases and related facilities in Japan, with Okinawa Prefecture alone hosting more than half of United States Forces Japan personnel. The JCP adheres to the idea that Japan, as an Asian country, must not allow its relationship with the United States and the G8 to define its foreign relations and should put its East Asian neighbors at the center of its diplomatic efforts. It supports establishing an "independent foreign policy in the interests of the Japanese people" and rejects "uncritically following any foreign power".
The JCP advocates that Japan issue further apologies for its actions during World War II and has condemned prime ministerial visits to Yasukuni Shrine. In the 1930s, while the JCP was still illegal, it was the only political party to vocally oppose Japan's war with China. The JCP supports Japanese territorial claims over the Kuril and Senkaku Islands and Liancourt Rocks. Furthermore, the JCP has condemned North Korea's nuclear-weapons testing, calling for effective sanctions, but opposing the prospect of a military response.
The JCP's leading politicians are known to be the most active opponents of anti-Korean racism and xenophobia in Japan. Contemporary JCP politicians criticize mainstream Japanese politicians for instigating contempt towards Korea, and oppose historical revisionism in regard to Korean history and Japanese war crimes. The JCP was one of the few Japanese parties which supported the Korean independence movement. In the latter half of the 1940s, a training school for Korean revolutionaries was operated jointly by the JCP and several Korean organizations, including the Communist Party of Korea. In South Korea, the JCP is known as the only "pro-South Korea" political party in Japan. Although it is illegal to form a communist party in South Korea, Mindan maintains friendly relations with the JCP. In 2003, due to the consideration of the then liberal South Korean president Roh Moo-hyun, formal exchanges between the JCP and the South Korean government began.



Pacifism

The JCP has traditionally championed pacifism. With regards to the Japan Self-Defense Forces (Japan's armed forces), the JCP's current policy is that it is not principally opposed to its existence (in 2000 the party stated that it would agree to its use should Japan ever be attacked), but that it will seek to abolish it in the long term, international situation permitting. The JCP opposes the possession of nuclear weapons by any country, military blocs, and attempts to revise Article 9 of the Japanese Constitution, which says that "never again ... [will Japan] be visited with the horrors of war through the action of government". Regarding the resolution of disputes, it argues that priority must be given to peaceful means through negotiations, not to military solutions. The JCP says that Japan must adhere to the United Nations Charter.



China and Soviet Union

The JCP took a neutral stance during the Sino-Soviet split and Miyamoto believed that it was unnecessary for the JCP to take a side. A pro-Chinese faction under the leadership of Hakamada Satomi and pro-Soviet faction under the leadership of Yoshio Shiga and Shigeo Kamiyama existed within the JCP. However, both groups were in the minority compared to the neutral faction.
Another pro-Soviet faction of the party was under the leadership of Shōjirō Kasuga. Kasuga's faction formed the Preparatory Commission for a Socialist Reform Movement on 9 October 1961. This group broke away on 3 May 1962, and formed the Unified Socialist League with 600 members. Relations between the Soviet Union and JCP soured as the Soviets attempted to court the JSP. Shiga and Ichizo Suzuki were expelled from the party for voting in favor of the Partial Nuclear Test Ban Treaty in 1963. Shiga and Suzuki were praised in Soviet publications, including Pravda. The publication of Shimbun Akahata faced restrictions in the Soviet Union while Shiga's Voice of Japan did not.
The JCP supported China during the Sino-Indian War. Miyamoto announced the JCP's opposition to the 1968 Soviet invasion of Czechoslovakia. At the same time, the party had distanced itself from Mao and Maoism, which allowed it to avoid being associated with China's Great Leap Forward and Cultural Revolution once they started coming more fully to light in the 1970s. In July 1969, the JCP declared that if it ever came to power, it would permit the free functioning of opposition parties, in an effort to distinguish itself from the one-party states in the Soviet Union and China. A purge of pro-Chinese elements in the JCP, including Tokuda's son Nishizawa Ryūji from the Central Committee, was conducted in 1966. In 1976, mentions of "Marxism–Leninism" in the party program were changed to "scientific socialism".
In 2020, the JCP revised its platform for the first time since 2004. The new platform criticized the Chinese Communist Party, denouncing China's "great-power chauvinism and hegemonism" as "an adverse current to world peace and progress". The JCP also removed a line from its platform which described China as a country "that is beginning a new quest for socialism". JCP members have stated that this was due to human rights conditions in China. The Ministry of Foreign Affairs of China denounced the accusations of the JCP as "groundless and biased".




Organization


The party officially upholds democratic centralism. The party constitutions states decisions "shall be based on democratic discussion and finally decided by majority vote" and that "there shall be no factions or splinter groups". Along with Komeito, the JCP is unique amongst major Japanese political parties for the continuity of its leaders, with Shii having served as JCP chairman from 2000 to 2024.




= 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. The current chairman of the executive committee of the Central Committee of the JCP is Tomoko Tamura. The Central Committee also appoints the Disciplinary Commission and the Audit Commission, and may elect a Central Committee chairperson; the current Central Committee chair is Kazuo Shii.
The executive committee manages party affairs between Central Committee meetings. It appoints the members of the Secretariat, which manages the day-to-day affairs of the party center, and the Central Organ Paper Editors Commission. It also elects the Standing Committee of the executive committee.




= 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 Kyoto, Osaka and Kobe, Shinetsu Red Flag in Nagano and Hokkaido News in Hokkaido. They also published numerous (the exact number is unknown) factory newspapers.
Some regional newspapers, such as Shin Kanagawa (Japanese: New Kanagawa) in Kanagawa, are still published.




= Affiliated organizations

=
The youth wing of JCP is the Democratic Youth League of Japan. In the 1920s and 1930s, the organization published several newspapers of its own, including Rēnin Seinen (English: Lenin Youth) and Proletarian Youth.
The party also has affiliate medical and consumer co-ops. The Japanese Consumers' Co-Operative Union (JCCU), the umbrella body of the co-operative movement in Japan, has a sizable number of communists in its ranks, although the exact numbers are difficult to verify. Another example of the JCP's prevalence in the co-operative movement is the Co-op Kanagawa in the Kanagawa Prefecture, which has 800,000 members and has historical ties to the JCP. It still advertises and occasionally is published in JCP newspapers such as Red Flag and New Kanagawa. The prevalence of house unions in Japan as opposed to enterprise unions has prompted much of the exceptional development of other organizations by the JCP, as well as causing the JCP to seek other external organizational support, including from kōenkai.

The Choir of JCP-fans (JCPファン雑唱団, JCP-fan zassyōdan) is a musical group which supports the JCP. Its repertory and artistic activity are strongly linked to The Singing Voice of Japan (日本のうたごえ, Nihon no utagoe) / うたごえ運動 Utagoe-undō), a musical movement of Japanese working class that dates back to 1948, when the Choir of the Communist Youth League of Japan (日本青年共産同盟中央合唱団, Nihon-seinen-kyōsan-dōmei Chuō-gassyōdan) was established. The group was founded in Kyoto in 2011 and is directed by Tadao Yamamoto, a composer, accordionist, choir director, and ordinary member of the National Council of The Singing Voice of Japan. In various cultural events organized by the party, the Choir of JCP-fans appears as an element among the joined choirs of the volunteer singers of The Singing Voice of Japan. As of 2016, the choir is the only organization of Japanese musicians specializing in political support and in the cultural activity of the party.
Notable concerts and performances by the choir include:

11 February 2011, Kyoto Kaikan Hall: Concert sponsored by the Kyoto Committee of the Japanese Communist Party (JCP).
1 August 2013, Nishijin Bunka Center (Kyoto): Cultural Live Revolutionary Pub, in collaboration with Tokiko Nishiyama (西山登紀子), former JCP member of the House of Councilors.
23 September 2014, Takaragaike Park (Kyoto): Festival Kyoto ed. 2014, organized by the Kyoto Committee of the JCP.
1 February 2015, Kyoiku Bunka Center (Kyoto): Festival sponsored by the Kyoto Committee of the JCP.
29 April 2016, Takaragaike Park (Kyoto): Festival Kyoto ed. 2016, organized by the Kyoto Committee of the JCP: performance with Seifuku Kōjō Iinkai (制服向上委員会) and Akira Koike (小池晃), JCP member of the House of Councilors and Secretary-General of the party.




Membership


44.09% of the JCP's membership in 1966 was between the ages of 30–39, 27.50% were below 29, 15.21% were 40–49, 8.81% were above 50, and 3.74% were of an unknown age. The most common form of employment was in factory work, civil service, education, and agrarian work. During the 1980s, party membership began to decline, falling to 500,000 by 1990 and 370,000 by 1997.
Following its advancement in the 2013 Tokyo prefectural election, the party enjoyed an increase in membership growth, with over 1,000 people joining in each of the final three months of 2013. Approximately 20% of new members during this period were aged 20 to 40, showing a higher ratio of young people joining the party than in the past. The JCP had approximately 320,000 members in January 2014.
More recently, however, membership numbers have declined, with membership around 300,000 in 2017, 270,000 in 2020, and 250,000 in 2024.

Electoral performance






= House of Representatives

=
Prior to 1996, the entire House of Representatives was elected by majoritarian or "semi-proportional" voting systems with votes cast for individuals (1946: limited voting in multi-member districts, 1947 to 1993 SNTV in multi-member districts). Since 1996, the House of Representatives is elected in a parallel election system—essentially two separate elections only in the lower house complicated by the fact that a candidate may stand in both segments and the sekihairitsu system which ties proportional list ranking to FPTP results: only the majority of members the House of Representatives, 295 (initially 300) seats, are elected in a majoritarian system with voting for candidates (first-past-the-post 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. This continued a new wave of support that was also evident in the 2013 Tokyo prefectural election in which the party doubled its representation. Fighting on a platform directly opposed to neoliberalism, the Trans-Pacific Partnership, attempts to rewrite the constitution, United States Forces Japan, and nuclear power, the JCP tapped into a minority current that seeks an alternative to Japan's rightward direction. Following the 2016 Japanese House of Councillors election, the party held 13 seats in the House of Councillors. After the 2017 Japanese general election, the party held 12 seats in the House of Representatives, and since the 2021 Japanese general election, it holds 10 seats.




= 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.
