6 Cheapo Pools in Tokyo

What better way to cool off than a trip to one of Tokyo’s water parks? Going to the pool with friends is a great way to beat the heat during the summer, but one look at the 4,500 yen price tag of Tokyo Summerland is enough to send you scampering back to the (cheap) safety of your own home and running a cold bath.

While the biggest water parks in Tokyo are often accompanied by an even bigger entry fee, there are plenty of smaller water park gems hiding in the region. Rather than just giving you the ‘cheapest of the cheap’ (which, really, is a paddling pool on a rooftop), we want to give you what we think are some of the best value water parks in Tokyo.

If you’re willing to sacrifice the glamour of a new water park in favor of a more affordable option, check out these top cheapo picks:

1. Rainbow Pool and Water Playland

The Rainbow Pool and Water Playland is a family favorite in Tachikawa’s Showa Kinen Park. The biggest in the metropolitan area, it is 1.4 times the size of Tokyo Dome (so plenty of room for splashing). The Rainbow Pool is more for adults and groups of friends, with nine pools spread over 6.3 hectares. They have wave pools, plenty of decent slides and relaxing river pools to float around to your heart’s content on a  sunny day.  It is also perfectly acceptable to lounge around in other parts of the Showa Kinen Park still in your swimsuit, so if you’re looking for a place to tan and swim (which isn’t as mainstream in Japan as in Western countries), Rainbow Pool is the place for you. The smaller Water Playland is mostly for kids and has a nice, safe toddlers pool. Hot showers, hair dryers and changing rooms are all available as well as baby changing areas.

You can (and should) bring your own towels, tarps, flotation devices, and water toys, but some things, like rings, are available to rent.

Price

The pricing system varies. Regular tickets for adults are 2,500 yen for adults, 1,400 yen for elementary and middle school students, and 500 yen for small children. You can buy discount tickets at a Lawsons or Family Mart, and should be able to get a discount if you pay for your ticket inside the water park with a SUICA or PASMO. If you are willing to enter the park after 2 pm (sunset apparently), you can get 50% off your ticket. You also get price reductions if you go as a group. You can rent boats (500 yen an hour) and small private areas with deck chairs for the day too. Pay first to get into the park and show your ticket stub at the Rainbow Pool.

• Address: 3173, Midori-cho, Tachikawa, Tokyo, 190-0014
• Closest sation: JR Tachikawa Station (15 min walk) or Nishi Tachikawa Station (5-minute walk)

2. Meguro Citizens Center Gymnasium and Pool

The Meguro Citizens Centre Gymnasium outdoor pool is perfect for the cheapo that wants to get the Japanese pool experience without shelling out serious yen. There are basketball, volleyball, and badminton courts, a weight training room, and a heated indoor pool that you must pay extra to use. The Meguro Citizens Center Pool is a quaint and fun pool for someone who is interested in swimming for a couple hours, but does not want to commit to a full day trip to a water park in Tokyo. It doesn’t have any water slides or extra gimmicks, so if you’re looking for a more interesting pool experience, bring your own (small) inflatable toys or flotation devices.

• Price: Regular tickets for adults are 200 yen for 2 hours. Tickets for students and the elderly are 100 yen for 2 hours. After 2 hours, you will be charged 150 yen per 90 minutes.
• Hours: 10 am to 8 pm. Open from July 1st to early September (exact dates vary by year)
• Address: 2-4-36 Meguro, Meguro, Tokyo  153-0063
• Closest station: Meguro Station on the JR lines.
• Phone: 03-3711-1139

3. Wadabori Outdoor Pool

This pool has been gaining fame lately because of its gorgeous scenery and friendly atmosphere. It is by far the most relaxing pool you can find in Tokyo, partly because it is well outside the main hustle and bustle of the city.

Its main charm point is the fact that the pool sits next to a picturesque woodland temple and the ever-charming Zenpukiji River. However, in the end, it is simply a pool, so if you bring your own (small) flotation devices and cover up any visible piercings and tattoos, you will have a wonderful time.

• Price: Regular tickets for adults are 500 yen for 2 hours; children’s tickets are 250 yen for 2 hours; free for children under 3. Every extra hour afterward is 250 yen for adults.
• Hours: 9 am to 6pm (Pool is open from July 1st to September 10th)
• Address: 2-2-10 Omiya, Suginami-Ku, 168-0061
• Closest station: Nishi-Eifuku Station on the Keio Inokashira Line
• Phone: 03-3313-4455

4. Oiso Long Beach in Kanagawa

Like the name suggests, Oiso Long Beach Water Park is not just a regular water park; it is an interesting fusion of beach and water park. Perfect for young families and older guests, this water park has a wave pool, a lazy river, plenty of places to lounge, a number of different pools and hot tubs, and an Olympic-sized diving board. The only downside to this cheapo favorite is the fact it is in Kanagawa, a fair distance from Tokyo. However, unlike some of the other famous water parks in Tokyo proper, Oiso Long Beach is less crowded and more relaxed. Also, because the beach sits south of Kamakura, the waters are clear and noticeably devoid of seaweed and debris.

A word of warning, though: if you have a tattoo, make sure to cover it up as Oiso Long Beach is known for cracking down on patrons with visible tattoos.

• Price: The pricing system varies. Regular tickets for adults are 4,200 yen, but if you are willing to enter the park after 2:00pm, you can get a discounted ticket for 2,500 yen. See the Oiso Long Beach website (in Japanese) for more information on prices. If you follow this link and have Line, you can get vouchers to use too.
• Hours: 10 am to 5 pm (Park is open from early July to mid-September)
• Address: 546 Kokufuhongo, Oiso-machi, Naka-gun, Kanagawa, 259-0111
• Closest station: Oiso Station on the Tokaido Line. Take the shuttle bus from Oiso Station to Oiso Long Beach. An adult bus ticket is 200 yen and a child’s ticket is 100 yen.
• Phone: 0463-61-1111

5. Kawagoe Aquatic Park

Under 40 minutes from Ikebukuro, Kawagoe Aquatic Park is an easy trip for those cheapos who live close to Saitama. It’s one of the more reasonably priced water parks in Kanto—with slides of varying levels of scary and a couple of large family pools. There is also a shallow wave pool where it is quite nice to chill. The place can get crowded and there isn’t much shade, so come prepared to deal with the heat. Flotation devices are welcome. Cheap food is available.

• Price: Regular tickets for adults are 720 yen
• Hours: 9 am to 5 pm (Open mid-July to early September; hours are typically extended to 6pm between the 21st of July and the 16th of August)
• Address: 880 Oaza-ikenobe, Kawagoe-shi, Saitama
• Closest station: Nishi-Kawagoe on the JR Kawagoe Line
• Phone: 049-241-2241

6. Aquafield Pool, Minato

If you want a pool with a view, then look no further. With views of Tokyo Tower and the lush Shiba Koen park with Zojoji Temple, this is a great place to relax and pretend you’re living the life of luxury. The 50 meter pool has some sections cordoned off for serious swimmers but the rest is open for play. However, with recliners but only some parasols and no natural shade, beware of the sun. Technically, sun block is banned here, but we unofficially definitely recommend you put some on, maybe just rinse off before you get in the pool. There is also a futsal area but this requires registration to reserve and use. Check the website here for more details and a small map.

• Price: 600 yen for adults and 100 yen for children (extended use is 300 yen/hour for adults and 50 yen for children)
• Opening Times: 9 am to 8 pm (5 pm in September) and open from July 1st to September 15th.
• Address: 2-7-2 Shibakoen, Minato-ku 105-0011
• Closest station: Shiba Koen Station on the Mita Line (1 min) or Daimon station on the Oedo and Asakusa Line (5 mins)
• Phone: 0357330575
