I read that Enzan is sometimes called 'Kamakura in Koshu', because it has several important and beautiful temples. Kogakuji is one of these temples. It is one of the head temples for the Rinzai sect of Zen Buddhism, and has eight sub-temples within the precincts. The setting at the foot of a green mountain was particularly beautiful, and the pond with its unusual covered bridge was also lovely. I hope I can return here in spring or autumn... or maybe both!
After you visit Kogakuji I recommend you also see nearby Erinji and Hokoji.
