Nichiu; 日有; (1402–1482); The ninth chief priest of Taiseki-ji, the head temple of the Nikko school (also known as the Fuji school), or what today is called Nichiren Shoshu, in Japan. A land dispute between two factions of priests had lasted for seventy years at the temple after the death of Nichimoku, the third chief priest. Nichiu contributed to the restoration of Taiseki-ji, repairing its buildings and educating the priests. He went to Echigo, on the Sea of Japan, and to Kyoto to propagate the teachings. In 1432 he submitted a letter of remonstration to the emperor. He instructed the priests from various areas on the formalities of the school, and his disciple NanjoNichiju compiled those instructions as Reverend Nichiu's Teachings on the Formalities.
