Kai-Zenkoji Temple

Kai-Zenkoji (甲斐善光寺, Kaizenkōji) is a large temple in Kofu, built in the 16th century by warlord Takeda Shingen. Fearing destruction during local battles, Shingen moved treasures from the famous Zenkoji temple in Nagano to this new location. The temple is often referred to as Kai-Zenkoji, named after the old region of Kai, to distinguish it from the Zenkoji temple in Nagano.

A standout feature of the temple is its impressive Sanmon Gate and the main hall, which is the largest wooden building in eastern Japan. Inside, visitors can experience a unique underground passage in complete darkness, in search of the "key to paradise." This key, said to offer salvation to those who touch it, adds a spiritual touch to the visit. Additionally, the main hall offers a special acoustic spot where visitors can clap and hear the sound resonate through the wooden ceiling.
