Although Japan doesn't get nearly as hot as the southern United States during the summer months, there's still nothing quite like hanging out at a water park or public pool to beat the summer heat. Fortunately, 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 escape the heat with a relatively small crowd.

As with all tourist attractions, be sure to check the associated websites for more information about hours of operation, special holiday closures, and pricing rates before you make your trip in order to avoid any unexpected surprises. As of early 2018, the following eight pools, waterparks, and other water attractions are the most popular you can choose from for your visit to...MORE Japan.
