Kuon-ji (久遠寺) is a major Buddhist temple in Yamanashi Prefecture, Japan. Founded by Nichiren in 1281 it is today the head temple of Nichiren Shū. While the Ikegami Honmon-ji in Tokyo is also the Nichiren sect's administrative centre, Kuon-ji today plays an important role as a seminary. Locally it is referred to as the Minobu-san Temple, after the mountain upon which it is built.
