Kochoji Temple located in Okanomiya, Numazu City, Shizuoka Pref. is one of the four major head temples of the Hokke sect of Buddhism. The principal object of worship is the Hokke Mandala written by Nichiren Shonin himself. The time of its foundation is not known. It is said to have been a Tendai sect temple before 1276, when the resident priest Kuzon became a disciple of Nichiren and was given a new name, Nisshun. He changed the name of the temple to Tokuei-san Kochiji Temple. Thereafter, the founder of the temple is to be Nichiren and the second generation resident priests to be both Nisshun and Nippo.
The main hall was built in 1311, and through several construction works it became a large temple. However, all the buildings except the main hall and San-mon Gate were burnt down in two fires. The main hall was restored to the present form in recent years. The temple is visited by a lot of cherry blossom viewers in spring.
