Steam SaunaAbout
Ryuguden Honkan is a day-use bathhouse on the shore of Lake Ashi in Hakone, drawing on Takogawa (蛸川), the newest of Hakone's seventeen hot springs. Both the men's and women's sides have an indoor bath and a rotenburo open-air bath facing Fuji and the lake. The men's side adds a Finnish-style sauna, a lukewarm bath and a cold bath; the women's side has a steam sauna instead. The water is clear and a little smooth on the skin. The building has its own history. It started out as the Hamanako Hotel (浜名湖ホテル), founded in 1938, a high-end ryokan that once hosted members of the imperial family and foreign dignitaries, and was later moved to this site. It now operates purely as a day bath. Lunch is served at the dining hall Fuji, there is a gift shop by the front desk, and three separate rest areas: the shared lounge Juraku (聚楽), the women-only room Yugiri (夕霧), and a quiet relaxation room.
