He was taken into custody in his capacity as Soka Gakkai's Youth Division Chief of Staff for overseeing activities that constituted violations of election law.

In the 1960s it was widely criticized for violating the separation of church and state, and in February 1970 all three major Japanese newspapers printed editorials demanding that the party reorganize.

The Japan Echo alleged in 1999 that Soka Gakkai distributed fliers to local branches describing how to abuse the jūminhyō residence registration system in order to generate a large number of votes for Komeito candidates in specific districts.

[34][35] In July 2015, Komeito backed Prime Minister Shinzō Abe's push to revise the Constitution in order to "give Japan's military limited powers to fight in foreign conflicts for the first time since World War II".

[attribution needed] This legislation, supported by the United States, would allow the "Self-Defense Forces to cooperate more closely with the U.S. by providing logistical support and, in certain circumstances, armed backup in international conflicts" and "complements guidelines in a bilateral agreement governing how Japanese and United States forces work together, which was signed by the two nations" earlier in 2015.

[40] On 24 April 2019, joint task force efforts with its coalition partner[41][42][43] resulted in the passing of a bill mandating reparations and having the coalition government issue a formal apology to sterilization victims of the defunct Eugenic Protection Act, thus to advance human rights awareness in the wake of lawsuits[44][45] related to the history of eugenics in Japan.

[50] Komeito regards the Soka Gakkai as a "major electoral constituency",[51] having formally separated from the religious group and revised both its platform and regulations in 1970 to reflect a "secular orientation".

[51][58] Numerous Japanese religious groups have established political parties in Japan, but statistics scholar Petter Lindgren states that "None have, however, been more successful than Soka Gakkai.

[60] In accordance with its public affairs transparency platform, it was reported that since September 2016, the Komeito conducted independent analyses for possible environmental contamination of the proposed Toyosu market site.

[61] The Komeito officially raised its environmental concerns later regarding Toyosu market during the 5 October 2016 Tokyo Metropolitan Assembly Session.

[60] Later softening its views, Komeito later backed LDP proposals such as a 2004 vote to dispatch the JSDF to support allied operations in Afghanistan and Iraq, and prime minister's Shinzo Abe's revision of the security laws to expand military powers in July 2015,[36] although it did manage to moderate the policy on the latter.

"[60] Komeito's then leader Yoshikatsu Takeiri's held negotiations Chinese Premier Zhou Enlai in the 1970s played a critical role in the eventual normalization of relations between the People's Republic of China and Japan in 1972.

[60] The party reportedly advocates for improved ties with China and South Korea in light of Japan's historical war crimes in both territories.

In 2013, the party's chief representative Natsuo Yamaguchi praised Prime Minister Shinzo Abe's decision not to visit Yasukuni Shrine, where Japanese war criminals are enshrined.
