A swimsuit-on onsen theme park. Wine, coffee, green tea and sake baths sit side by side under one roof, each with its own colour and smell. There are also flowing pools and slides, so it feels more like an indoor water park than a quiet soak. The separate Mori no Yu, where you bathe nude, is next door and covered by a combined passport ticket.
