The Kokuchūkai (国柱会?, "Pillar of the Nation Society") is a lay-oriented Nichiren Buddhist organisation. It was founded by Tanaka Chigaku in 1880 as Rengekai (蓮華会?, "Lotus Blossom Society") and renamed Risshō Ankokukai (立正安国会?) in 1884 before adopting its current name in 1914.
Originally based in Yokohama, the group shifted its head office to Tokyo, Kyoto-Osaka, Kamakura and Miho, Shizuoka Prefecture before finally moving back to Tokyo. The group is currently based in Ichinoe, Edogawa-ku.
Among the group's principal teachings are to return to the teachings of the founder of Nichiren Buddhism, the 13th-century monk Nichiren and unite the various sects of Nichiren Buddhism. The group's teachings are characterized by a strong form of Nichirenism.
At its height in 1924, the group's membership was estimated at over 7000. The literary figures Takayama Chogyū and Kenji Miyazawa were members of the Kokuchūkai for a time. The group's official website continues to claim them, but they ultimately rejected Tanaka's nationalistic views.
