Nichiren Shōshū
These and other conflicts resulted in a complete and formal disassociation of the two sides after Nichiren Shōshū excommunicated the leaders of the Sōka Gakkai and stripped it of its status as a lay organization of Nichiren Shōshū in 1991. Ultimately, Daisaku Ikeda was excommunicated from the role of "Sokoto" or lay leader by High Priest Nikken, while the formal decree of excommunication invalidated the tax exempt status of Soka Gakkai under Japanese law due to its lack of temple affiliation.
