Yasuda Yoshisada, who coalesced with Minamoto Yoshitsune in the Genpei War and demonstrated the capabilities of a general, was defeated by Minamoto Yoritomo in 1194. Thereafter, Yoshisada’s third son Yasuda Yoshiyasu committed suicide and was buried in Jokokusan Anyo-ji Temple that was built in 1197. Roughly 400 years later in 1590, Anyo-ji Temple was relocated to its present location by Kato Mitsuyasu, a military commander under Toyotomi Hideyoshi, and it was renamed as Dounji. The main deity of Doun-ji Temple is a wooden seated image of Amidanyorai 25.6cm tall, dating from the Edo Period (1603-1868). It is designated a Tangible Cultural Property of Yamanashi City.
On the grounds of the temple stand a memorial monument for Kato Mitsuyasu, in addition to a Yatsubusa-no-ume plum tree that is a designated Natural Monument of the prefecture, and a weeping cherry tree that is more than 150 years old. Also in the precincts are a large image of Buddha entering nirvana, a Kannon image, an image of Sanzohoshi, more than two hundred Mizuko Jizo deities and various other stone Buddhist images.
