History and Highlights

Tokyo Summerland is a leisure facility surrounded by the rich nature of Akiruno City, including mountains and rivers. In addition to pools, there is an amusement park along with rides for children, making it enjoyable for families.

Its origins date back to Tokyo Circuit Co., Ltd., established in March 1966. In July 1967, it opened Summerland, an indoor leisure facility full of tropical ambiance. In September 1970, the current operating company, Tokyo Summerland Co., Ltd., was established. Covering an area of approximately 1.3 million square meters, it is a comprehensive leisure complex centered around indoor and outdoor pools and an amusement park.

In recent years, it has adopted the new concept of an "Adventure Resort of Water and Greenery." The exterior of the large dome was renovated in dark gray and white to harmonize with the surrounding nature and landscape. The rows of pillars are inspired by trees. The first-floor entrance hall features the theme of "water and greenery," and Tama timber grown in the Tama area is used for part of the building materials.
