Kai Zenkoji Temple
A renowned temple founded in Eiroku 1 (1558) by Takeda Shingen, a Sengoku-era warlord of Kai (present-day Yamanashi Prefecture). Fearing that Zenkoji Temple in Nagano might be destroyed by fire during the Battles of Kawanakajima, Takeda Shingen moved the principal image of Amida Nyorai and other Buddhist treasures to Kofu, which marked the beginning of the temple. Even after the fall of the Takeda clan, the temple continued to receive generous protection from Tokugawa Ieyasu and others.
The Buddha statues and decorations inside are incredibly detailed. You can really feel how deep the Buddhist culture is.
