Since then, the Study Group has been holding meetings and events on a regular basis, covering such issues as comfort women, territorial disputes, Imperial Family, national defense, Constitution, etc.

The Study Group has co-sponsored nationalist events with Himawari Japan and Global Alliance for Historical Truth, including Himawari Japan lectures (2016) and Himawari Japan lectures (2017).

The group organizes frequent demonstrations against the Korean Embassy and Mindan over history, territorial disputes, and other issues.

Ninohashi Club submitted a two-page position paper to the United Nations Committee for the Elimination of All Forms of Discrimination Against Women in 2016 which disputed the historical orthodoxy on comfort women–see Alliance for Truth About Comfort Women Geneva Delegation (2016).

It was formed as the Party for Future Generations in 2014 by former Tokyo governor Shintaro Ishihara and others as they split from the Japan Restoration Party. The party changed its name to the Party or Japanese Kokoro in 2015.

In December 2013, members of Restoration Party visited California to urge local Japanese Americans to oppose the Comfort Women memorial in Glendale. The delegation consisted of Mio Sugita, Hiromu Nakamaru, and Yuzuru Nishida. Japanese American representatives rejected their historical revisionism.

The party was founded with 22 incumbents in the Parliament, but was decimated over the next two elections to only two members.

Study Group for Japan’s Rebirth

Study Group for Japan’s Rebirth (日本再生研究会) is a monthly study group on modern Japanese history founded in 2006 by comfort women denier Koichi Mera. The meetings were held in Japanese mainly for “shin issei” (new first generation) Japanese immigrants according to Mera. As of 2014, annual membership is $60.

Unlike Mera’s other group, Global Alliance for Historical Truth, the Study Group has largely remained unnoticed from the non-Japanese speaking public because it had not exerted itself into public controversies outside the Japanese speaking communities. However, in 2016 the Study Group collaborated with two similarly minded groups from Japan to submit a joint proposal that seeks to deny the historical orthodoxy on comfort women to UNESCO’s Memory of the World Register.



Toronto Seiron

Toronto Seiron (トロント正論の会) is a group made up of Japanese nationalists and comfort women deniers in Toronto, Canada. Leaders include Sharon Isac and Toshie Marinov, both Japanese women married to Canadian citizens.

In August 2016, Toronto Seiron hosted Shiro Takahashi and Shinichi Tokunaga, who also spoke at Himawari Japan Lectures (2016) in New York City, to present about the comfort women issue and “preserving Japanese spirit” while living outside of Japan.

Earlier in the same month, members of Toronto Seiron also infiltrated a memorial tribute to the victims of Hiroshima atomic bomb attack with offensive signs calling for Japan’s re-armament and denying Nanking atrocities.


Zaitokukai (在特会) or Zainichi Tokken o Yurusanai Shimin no Kai (在日特権を許さない市民の会) is a far-right extremist group known for violent rhetorics and actions against ethnic Korean communities and other minorities in Japan. Ever since its founding in 2006, Zaitokukai is also known for racist and misogynist attacks on former comfort women. The most notorious incident occurred in 2010 in which members of Zaitokukai and allied groups showed up in front of a Korean elementary school in Kyoto, banging on its gate and screaming racist epithets.

The group was founded by Makoto Sakurai, the president of the organization until 2015, who later ran for the governor of Tokyo in 2016. Another prominent leader of Zaitokukai was Yumiko Yamamoto, who served as the vice president and the secretary general until 2011 when she decided to focus her energy on Nadeshiko Action, a “women’s” organization focusing on comfort women denial.

After Sakurai founded Japan First Party in late 2016, some chapters of Zaitokukai transformed themselves into chapters of the party.
