Hakone Kowaki-en Yunessun

Hakone Kowaki-en Yunessun


This recreational facility consists of 2 areas: the “Yunessun” play area for playing in the water in bathing suits and the “Forest spa” relaxing hot spring bathing area. “Yunessun” contains some unique baths, such as the “authentic coffee bath” and the “open-air wine bath,” as well as “Rodeo Mountain,” Hakone’s only water slider. There’s also “Doctor Fish’s footbath,” which provides a unique sensation, and the “floating bath.” All of these are to be enjoyed in bathing suits. “Forest spa” boasts a magnificent view of Hakone’s volcanic peaks from the open-air bath. The cypress bath and the ceramic bath made with Shigaraki pottery provide a Japanese traditional atmosphere. The facilities also include a lounge where visitors can lie down and take a rest, and a relaxation room offering spa treatments and massages. It is an all-weather recreational facility, for enjoyment and relaxation rain or shine!
