There are many temples and shrines in Yamanashi perhaps partly because it was governed by a powerful feudal lord Shingen Takeda. The architecture of those old monuments is worth visiting but apart from the architecture, there are beautiful Japanese gardens.

Japanese Garden in Erin-ji Temple
Erin-ji Temple in Koshu City, Yamanashi was a home temple for Takeda clan. It was opened in 1330 long before Takeda clan became powerful. Japanese garden of this temple was created by a monk Muso. He is famous for his another Japanese Garden in Moss Temple or Saiho-ji Temple in Kyoto.
Beside this garden by Muso, the temple has another garden. Unfortunately I could not check whether it was also designed by Muso or someone else. This garden depicts a pond and streams by gravels which is one of the typical styles of Japanese gardens.
