Tojuin Temple in Samani Town in southern Hokkaido is a temple of the Tendai sect, enshrining the statues of Amida Nyorai Triad as its principal object of worship. It is selected as one of the eight scenic spots in Samani Town. It was the head temple of the three historic temples founded in 1806 by the 11th Shogun Tokugawa Ienari as the official temples to hold a memorial service for warriors sent to Ezo (present-day Hokkaido).

The Goma Hall (the training ashram) was also constructed in 1811, but it was damaged by bear attacks and a flood of the river and relocated to another place. In 1965, when the new temple building was constructed, the Goma Hall was also restored to the original form. The temple possesses precious old documents concerning Buddhism, governments’ policies on Ezo and the history of the Ainu people including the diaries written by the 11 generations of the resident priest of Tojuin Temple, which are altogether designated as an Important Cultural Property by the national government.
