Koin-ji Temple is a Soto sect temple that houses the graves of Yanagisawa Gondayu Yasunori and his wife. Gondayu Yasunori was a castle keeper and chief retainer of Yanagisawa Yoshiyasu, lord of the Kofu Domain. The graves are located behind the main hall.
A spot on the grounds of the temple called Budogasaki offers a panoramic view of Kofu, and was also called “Shingen’s lookout” or “military garden.”
This temple is also where Prince Ryojun Shinno, a member of the Imperial family during the early Edo Period (1603-1868), spent 13 years after being demoted. The Koro Myojin Shrine he built in the temple precincts remain to this day.
The approach to the temple is lined with hydrangeas that add beautiful color to the temple grounds when they bloom in June.
