Indoor and outdoor pools galore at this epic leisure destination.
This large-scale leisure hub sits in Akiruno City, drawing crowds for its massive outdoor lazy river pool—one of the largest in Japan—and an indoor pool just waiting for you to dive in no matter what the season or weather. Pop over easily from Tokyo Station in just over an hour by train thanks to easy access that keeps this hot spot on the list.
The outdoor pool area, Adventure Lagoon, is open from July to the end of September. Its 650-meter lazy river is the highlight, surrounded by your choice of water slides and attractions for children. One fan favorite is the thrilling DEKASLA, a massage course made to glide through via inflatable boat. A new pool, Monster Stream, opened in June 2024, offering an adventurous, fast-flowing river-like experience using special floats that’s already generating buzz.
The indoor pool, Adventure Dome, features not only a massive pool but also water slides, jacuzzis, and a heated spa, providing a wide range of facilities for both children and adults to enjoy.
Admission includes a 1-Day Pass, which covers both entry to the pool areas and unlimited rides at the amusement park, offering a wide range of attractions from adrenaline-pumping to relaxing, ensuring a full day of fun for everyone.
