The Kenkokukai (建国会/建國會, National Foundation Society) was a Japanese secret society founded by Bin Akao in April 1926. It was an ultra-anti-communist organisation, strongly influenced by the National Socialism of Motoyuki Takabatake.

The predecessor of this association was the steering committee for the National Foundation Festival (建国祭), which was organized in opposition to May Day. It proclaimed its object to be "the creation of a genuine people's state based on unanimity between the people and the emperor".^[1] At its height, the organization reached a nationwide membership of around 120,000.

Goals

Its statist program included the demand for "the state control of the life of the people in order that among Japanese people there should not be a single unfortunate nor unfully-franchised individual".^[1] The organisation embraced Pan-Asianism declaring "The Japanese people standing at the head of the colored people, will bring the world a new civilization."^{[This quote needs a citation]} It was at one time in favor of universal suffrage.^[1]

The Kenkokukai worked in close concert with the police to break the miners strike in Tochigi, and other strikes by factory workers in Kanegafuchi, tramway workers in Tokyo, and tenant farmers in Gifu Prefecture. Uesugi soon withdrew in 1927, and Takabatake supporters left following his death in 1928. This left the organization with only around 10,000 members. Tōyama Mitsuru (頭山満) of the Black Dragon Society (黒龍会) was appointed honorary chairperson, and Nagata, a former Police Chief, vice-chair. Others of this new influx included Ikihara, Kida, and Sugimoto. Akao was director of the league, which organized gangs of strike breakers and in 1928 bombed the Soviet embassy.^[2] Their paper Nipponshugi was virulently anti-communist with slogans such as "Death to Communism, to Russian Bolshevism, and to the Left parties and workers' unions".
