And the bigger the attractions, the better, if their gigantic pools, monstrous waterslides and never-ending 'lazy rivers' (a kind of moving pool where you can float along on boats and other inflatables) are anything to go by. In true Japanese style, there's no shortage of novelty attractions to also get amongst—pools filled with coffee and wine, for example (we're not even joking). So what are you waiting for? Take the plunge and read on for Japan's eight best water parks. Tip: Remember to check each park's stance on tattoos before visiting—some have banned them altogether, while others simply require you to cover them up. ## Sunshine Pool, Fukuoka ![Sunshine Pool Fukuoka](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/307173/Sunshine-Pool-Fukuoka.jpg) Image: An aerial view of the sprawling Uminonakamichi Seaside Park / Supplied An epic family day out awaits at [this super-sized offering](https://uminonakamichi-sunshinepool.com/) by the sea (you'll find it inside Uminonakamichi Seaside Park). Clocking in at 300m long, the lazy river here is hard to beat, while the waterslides-—including one you can ride on a tandem raft, and another for the littlies—are as fun as they come. If you prefer relaxation to rides, check out the resort-style Forest Lake Pool, which is as tranquil as it sounds and one of six pools at the park. There's also a sweet jungle-themed play area for the kids. ## Yomiurland's Pool WAI, Tokyo ![Yomiurlands Pool WAI Tokyo](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/307177/Yomiurlands-Pool-WAI-Tokyo.jpg) Image: A view of Yomiurland's Pool WAI in Tokyo / Supplied This one claims to be the [greatest water park in Tokyo](https://www.yomiuriland.com/), and we might be inclined to agree. It's giving tropical island vibes with bright blue, palm-edged pools, and not by coincidence—in Fijian, the term 'wai' actually means water. This beachy paradise is home to five pools and eight waterslides, including the famous Giant Sky River, where you'll swish down an almost 400m course in a family-sized raft, while taking in epic views of the Tokyo skyline. Find it inside the popular Yomiuriland theme park. ## Tokyo Summerland, Kanto ![Tokyo Summerland](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/418790/Tokyo-Summerland.jpg) Image: There's no shortage of water-based attractions at Tokyo Summerland / Go Tokyo [Tokyo Summerland](https://www.summerland.co.jp/) is home to one of the most inclusive, family-friendly water parks in Japan, offering everything from relaxing indoor pools to hella scary waterslides (the Dekasla, for example, which sends you and a raft of four others plummeting down a dark tunnel, before spitting you out into a ginormous, black-and-white vortex). It also boasts the longest lazy river in Japan or as we like to call it, The Perfect Way To Regulate Your Nervous System After Surviving Aforementioned Slide. ## Nagashima Spa Land, Mie ![Nagashima Spa Land](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/Nagashima-Spa-Land.jpg) Image: The largest funnel slide in the world, The Abyss / Planet Attractions If you're all about the waterslides when visiting amusement parks (some might call that 'tunnel vision'), you'll love [Nagashima Spa Land](https://www.nagashima-onsen.co.jp/spaland/index.html). It has more of these bad boys than you can count, including the largest funnel slide in the world—the Mega Abyss. Slides aside, you'll also be treated to a wave pool, a lazy river, and a pool that mimics whitewater rapids. Oh, and a fun show where cannons spray water in time to music. ## Spa Resort Hawaiians, Fukushima ![Spa Resort Hawaiians](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/418798/Spa-Resort-Hawaiians.jpg) Image: Float alongside real fish on the Fish-Go-Round / Hawaiians The water park at [Spa Resort Hawaiians](https://www.hawaiians.co.jp/) combines an all-weather dome with water from the local hot springs, making it the perfect place to take a dip, year-round. Take said dip in the Fish-Go-Round, a lazy river-type attraction that runs alongside aquariums filled with more than 1300 tropical fish including small sharks; or throw caution to the non-existent wind (remember, we're inside here) with a ride on Japan's longest and tallest body slide, the Big Aloha. ## Yunessun, Kanagawa ![Yunessun](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/Yunessun.jpg) Image: Swim in a pool filled with coffee at Yunessun / Windowseat [Yunessun](https://www.yunessun.com/) has some of the most niche attractions of any water park in Japan, including a pool filled with drip-brewed coffee, and another into which staff pour bottles of wine (we're dead serious). Novelties aside, these pools are said to have various health benefits, particularly as they also contain natural spring water. If soaking in caffeine and booze ain't your thing, there are a bunch of other themed pools to explore; along with the famous Rodeo Mountain waterslide, which emulates the feeling of riding whitewater rapids. ## Himeji Central Park, Hyogo ![Himeji Central Park Poolside Kan Hyogo](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/307198/Himeji-Central-Park-Poolside-Kan-Hyogo.jpg) Image: Hyogo's safari-themed water park / Supplied This safari-themed amusement park (which, fun fact, also has a sister park in Kenya) features a [popular water park](https://www.central-park.co.jp/en/aquarea/) with dreamy, landscaped surrounds. Dive into a pool made to look like a beach, float along a lazy river, and soak up incredible views of the rest of the park from a unique tiered pool. Waterslides and an epic pirate-themed kids zone round out the attractions. ## Rusutsu Resort, Hokkaido ![Rusutsu Resort](https://d1g90p0r985xbs.cloudfront.net/general/_1280xAUTO_fit_center-center_82_none/Rusutsu-Resort.jpg) Image: Kick back and relax on the lazy river at Rusutsu Resort / Rusutsu [Rusutsu Resort's water park](https://rusutsu.com/en/events/outdoor-super-jumbo-pool/) offers some of the best water attractions in Japan, spearheaded by a 10,000m² outdoor pool (and a heated one at that). They're also fans of waterslides and the lazy river here, and offer a range of other pools both inside and out, for all swimming levels (props to the large, knee-deep number for kids learning to swim). Summer in Japan offers a diverse range of activities, including water parks that are perfect for cooling off in the summer heat. Whether you're looking for some refreshing water activities or escaping from the major cities, there's a perfect escape waiting for you.
