Onjuku Water Park

This water park is the closest to the ocean, where you can enjoy the sea breeze while in the pool. In addition to a 127m long lazy river, this pool also features a multi-purpose pool, a thrilling 74m long river slide, and a children's pool, so even small children can enjoy themselves. Although compact, it has a wide range of activities, making it popular with families, children's groups, and other small groups. (The slide cannot be used by people under 120cm tall.)
