日蓮正宗
During the 1970s, the Sōka Gakkai undertook a number of activities and propagated several notions that many in the Nichiren Shōshū priesthood and laity saw as deviations from traditional Nichiren Shōshū doctrine. Ultimately, the sentiment within the priesthood and traditional lay organizations grew so strong that a split became imminent, and, at a special leaders meeting held at Nichiren Shōshū Head Temple Taiseki-ji on 7 November 1978, termed the "Tozan of Apology", the senior leadership of Sōka Gakkai apologized to the priesthood and promised to correct the incompatibilities and never deviate from Nichiren Shōshū doctrine again. This apology was later printed in both the "Seikyo Shimbun" SGI magazine (November edition) as well as the manuscript of the "Dai-Nichiren" December 1978 publication.
