Rensokai

This is a group of Nichiren sects that works to propagate one another. The sects all have different doctrines but never refute each others errant doctrines

The Nichiren Shu, the Kempon Hokke, Honmon Butsuryu Shu, Hokke Shu Honmonryu, Hokke Shu Shinmonryu, Kokuchukai, Nipponzon Myohoji; Nichiren Honshu; Honmon Hokke Shu; Hokke Shu Jimonryu

Many Nichiren sects are also in the International Buddhist Union (they who displays the multicolored flags).

No remonstrations, no debates, only kumbaya

Needless to say, we will never be in the Rensokai nor the International Buddhist Union.
