Hakone Kowakien Yunessun
箱根小涌園ユネッサン
A leading hot-spring leisure facility in Hakone, made up of two areas: "Yunessun," a swimsuit-required hot-spring theme park, and "Mori no Yu," its counterpart for bathing in the traditional nude style. Yunessun, popular with families, features unique themed baths such as wine, coffee, and green tea baths, along with Hakone's only water slide and lazy river. Mori no Yu, by contrast, offers a quiet soak in outdoor baths surrounded by trees. Being able to experience these two contrasting hot-spring styles in one location is the facility's greatest appeal.
