At the summer pool of Kawagoe’s Aquatic Park you can get ‘slammed’ by 2m-high waves, which is considerably more pleasant than it sounds, and dive from the platform of a giant ship protruding from the middle of the pool. Your friends can view your plunge into the pool from the boat’s large underwater windows, so make sure to pull out some cool moves. Also, don’t miss the colourful curvy slides, perfect for racing against your friends (diving pool and slides usable from primary school students and older).
Note that tattoos, including fake ones, are prohibited at Kawagoe Aquatic Park's summer pool. Open July 13 to September 1 (closed July 16-19).
