A major spot with excellent access from the city center
Located next to Seibu Amusement Park in Saitama Prefecture, Water Jump S-AIR is about 60 minutes from Shinjuku on the Seibu Line from Tokyo. It's also a great water jump facility, easily accessible, just a 5-minute walk from Seibuen Station
There are nine kickers and a huge pool. The largest jump is 15m, the medium jumps are 8-10m, and the small jumps are 2-6m. First-timers can start on the beginners' practice platform (1m) and practice sliding on the artificial turf and getting a feel for being in the water
In addition to jumping, there are other activities such as a jib park, trampoline, and water japon. In the summer, it is bustling with freeskiers and families, and is the largest off-season training facility in the Kanto region. On weekends and holidays from the end of June to the end of September, and during August, there are also night skiing days until 10pm. Business people and students will also be pleased with the services they offer
Water Japon: A new and exciting activity from Japan
Water Japon is an activity that combines the exhilaration of a slide with the thrill of a jump, and anyone can try it using only their body, without having to wear skis or a snowboard. The exit is designed to face upwards, so you can enjoy the sensation of sliding and floating in the air at the same time, and experience an overwhelming sense of freedom
The jib area has been renovated and reopened!
The jib area has been renovated this season, and now features a wide box, flat-down box, 6m PVC rails, and two 5m rails. The safe design makes it easy to maintain balance, so it can be enjoyed by beginners and advanced riders alike. A new jib park and a dedicated lane for freestyle tricks are also under construction, expanding the ways to enjoy the area!
