Tokyo Summerland

Tokyo Summerland is a theme park and water park in Akiruno, Japan, located west of the capital and built with both indoor and outdoor sections. The site holds multiple swimming pools of varying depth, water slides at different heights, a wave pool, and classic rides such as roller coasters and carousels.

The complex opened its doors in July 1967 and targeted families from the greater Tokyo area seeking recreation in the mountains. During the 1970s, the site was expanded to welcome more visitors and add new attractions.

The name joins the capital with the promise of endless summer, a concept fulfilled by indoor pools and heated zones that stay open all year. Families and groups from the wider region treat the complex as a retreat where they can step away from city routines and spend time together near water.

The indoor sections stay accessible in any weather, while the outdoor areas see heavier use from spring through autumn. Visitors should wear comfortable shoes, as attractions spread across a wide site and some paths climb uphill.

On clear days, the mountains to the west stand visible from several viewpoints inside the complex, creating a rare pairing of rides and natural scenery. Some of the tallest slides offer brief glimpses of the surrounding valley before water speeds up the descent.
