The Zen Nippon Aikokusha Dantai Kaigi, known in English as the All-Japan Council of Patriotic Organizations, and known in short as Zen Ai Kaigi, was a Japanese ultranationalist federation which was founded in 1960 by far-right leader Yoshio Kodama. In the aftermath of the Anpo Protests, Zen Ai Kaigi became the leading Japan-wide federation of rightist groups, with a total membership of over 150,000 people from 440 groups. The group was led by Kodama and fellow ultranationalist leaders Tatsuo Amano, Kozaburo Tachibana, Tadashi Onuma, Ryoichi Sasakawa, and Giichi Miura. While Zen Ai Kaigi adhered to general rightist principles, it did not have a clear program. Early in its existence, Zen Ai Kaigi received a request from a steel fabricating firm in Chiba Prefecture to help the company with its labor problems by breaking up a strike, and it hospitalized 680 strikers in the ensuing brawl. So prevalent were yakuza among Zen Ai Kaigi's membership that some observers called it Yakuza Kaigi. The organization's second chairman and longtime boss, Keizo Takei, was a former yakuza who had worked as a spy and saboteur during the 1930s before becoming a Buddhist priest. Factions within the huge coalition were common, and, in April 1961, yakuza groups from the Matsuba-kai, Nippon Kokusui-kai, and Nippon Yoshihito-to subgroups split from the Zen Ai Kaigi to form the Nippon Jiyu Shugi Renmei, and, that same year, a more activist group loyal to Kodama formed within the Zen Ai Kaigi, the Seishi-kai. During the late 1960s, amid infighting within Zen Ai Kaigi, Kodama led the Seishi-kai in splitting with Zen Ai Kaigi.
