Butsugaiken Tea Room. Butsugaiken Chashitsu, a charming wooden tea room, features a single story and a traditional Kyogawarabuki roof. Inside, you"ll find two rooms adorned with three tatami mats each, along with a mizuya and kitchen area. This lovely tea room was moved to its present site in 1901 (Meiji 34). It belongs to the Omotesenke Fuhakuryu style, reminiscent of the Keshoan tea room at Gokokuji in Tokyo. Visitors can enjoy stunning views that beautifully complement the surrounding Japanese garden throughout the year.
