This hot spring theme park consists of two areas: The "Yunessan" area where visitors can have fun in swimsuits, and the "Morinoyu" area where they can relax and enjoy hot spring baths in the nude. The park also features an authentic coffee bath, an open-air bath with a spectacular view, a flowing pool, and the only water slide in Hakone.

The "Morinoyu" area boasts a landscaped open-air bath with a view of the Hakone mountain peaks. Private baths have been added and are getting ever popular. There is an additional rest area and a relaxation room where you can receive esthetic treatments and massages. Come enjoy this all-weather facility at any time of year!
