Although Japan doesn't get nearly as hot as parts of the United States during the summer months, there's still nothing quite as refreshing as hanging out at a water park or public pool. There are a number of great water-based attractions to visit on your summer vacation to Japan.

Most of Japan's outdoor swimming pools and water parks open in late June and close in early September, and although they can get quite crowded during school summer holidays from late July through August, you should be able to find at least one place to swim or cool off with a relatively small crowd. The parks are elaborate with specialty pools for children and adults. Many are part of larger amusement complexes. 

As with all tourist attractions, check the associated websites for these popular pools and attractions for more information about hours of operation, special holiday closures, and pricing. Most pools have rules posted including banning tattoos, which is not unusual in bathhouses and public pools in Japan.
