Nichijin
Nichijin is considered a founder of the Hokkeshū Jinmon Ryū subsect of Nichiren Buddhism, although it was announced by Nichiin. He studied under Nichiryū at Honjo-ji beginning at the age of 8, then left to study under Nichijō at 17.
While studying on Mount Chōkai he met a Tendai scholar, who he debated with. That scholar converted to Nichiren Buddhism in 1379 and changed his name to Nichijū. He also converted a Shingon priest who changed his name to Nichiin. He disappeared in 1419; it is believed he died on pilgrimage.
