Daizen-ji Temple

is a Buddhist temple belonging to the Shingon school of Japanese Buddhism, located in the city of Kōshū, Yamanashi, Japan. Its main image is a hibutsu statue of Yakushi Nyōrai, shown to the public every five years,

==History== The temple claims to have been founded in the Nara period by the monk Gyōki; however, the style of the main image is from the early Heian period, and written records only exist to verify the reconstruction of the main hall in 971 AD. The temple was the clan temple of the Saigusa clan, an ancient Gōzoku clan who controlled the eastern Kōfu basin. The temple was patronized by the Takeda clan in the Sengoku period, and in 1582, Takeda Katsuyori, fleeing defeat at the Battle of Tenmokuzan at Shinpu Castle at the hands of the armies of Oda Nobunaga and Tokugawa Ieyasu, spent one night at this temple. The nun Rikei subsequently wrote a history of the downfall of the Takeda clan, the "Rikei-ni no Ki", at this temple.
