In the Tama area of Tokyo, the bustling water park of Tokyo Summer Land makes a splash – literally. This water park is fun for all ages and just the place to beat the summer heat. 
Featuring several pools for all sizes, incredible and unique water flumes, warm water spas, exciting theme park rides, and a Ferris wheel! Take a dip in the massive 650-meter long lazy river, or interact with the 40-meter waterfall. There is also a large indoor pool kept at 30 degrees Celsius that is satisfactory for all times of the year. 
Please note that Tokyo Summer Land does not allow visitors with tattoos.
