GanbanyokuAbout
A forest resort on Lake Kawaguchiko, open to overnight guests only. Every suite comes with a private open-air onsen bath set in lava rock from Mt. Fuji, and most rooms have views of the mountain or the lake through the trees. The shared communal bath is gender-separated: men get a dry sauna and cold bath, women a mist sauna. The spring is the resort's own source, Nishikawa Onsen Reiho-no-yu (西川温泉 麗峰の湯). The top-tier suites also include an in-room ganbanyoku (岩盤浴, heated stone bed).
