Best Water Parks to Visit in Japan

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. They can get quite crowded during school summer holidays from late July through August; however, you should be able to find at least one place to swim or cool off with a relatively small crowd. The parks are elaborate, featuring specialty pools for both children and adults. Many are part of larger amusement complexes.

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