Tokyo Summerland is a sprawling water park in the Tama area of Tokyo. It's fun for kids of all ages and a great place to cool down during the Tokyo summer heat.
The park has several large pools, waterslides, pools for small children, warm water spas, rides for kids, and a Ferris wheel. The main outdoor pool is massive and features a 650-meter long lazy river. The park's outdoor waterslide has a 40-meter free fall. The large indoor pool has a tropical theme and is kept at 30 degrees celsius, so visitors can enjoy it all year round.
