Best Water Theme Parks Around Tokyo:

Don’t sweat it: 4 cool oases to beat the Summer Heat !

1) Summer Land
Not all cool spots, obviously, are indoors, so if it’s a water park you seek, Summerland and its almost reasonable ¥3,500 day-long entrance fee are the best choices by far.

The park’s 300-meter lazy river is the centerpiece, but there are also some exciting water slides and vertical freefalls where you can race your partner down on a float or inner tube.Adventure Lagoon is the outdoor water park area, but there’s also a well-frequented indoor wave pool that’s open year-round, but which can become incredibly crowded in a “Yamanote line Friday night commute” sort of way.

Open: July 1 – September 30, 2011 (The outdoor pool) *The indoor pool called Adventure Dome is open throughout the year.
Location: Akiruno-city, Tokyo

2) Toshima-en Water Park
Toshima-en is also a popular theme park in Tokyo. There are six different pools and many thrilling water slides in the water park including the Hydro-Polis – Body Ride Mountain A-Tower, which is basically just a fancy long name for their huge long windy waterside.

Open: July 1 – September 30, 2011
Location: Toshimaen Amusement Park 3-25-1 Kouyama Nerima-ku, Tokyo
Access: Seibu Ikebukuro Line / Seibu Shunjuku Line / Toei Subway Oedo Line Toshima-en Station

3) Yomiuri-Land
Yomiuri Land is a popular amusement park located in the suburban area in Tokyo. There are five swimming pools including a Diving pool with 3 diving boards, wave pool with 60 cm waves as well as three water slides including the Giant Sky River Slide, the Slalom Slide and a Straight Slide.

Open: July 8 to Sep. 11, 2011

4) Tobu Super Pool
The Super Pool features a huge wave pool, many different slides and many pools for the kids. One lap of the 300m “lazy river” is enough to cool you down. In addition, there are 11 “water cannon Cannon” located in the wave pool and also the music launch water.

Location: Tozu Dobutsu Koen (Tobu Zoo) Miyashiro-machi Minami-saitama-gun,

Bonus: Keep in mind that, like most public recreation facilities in Tokyo, anyone with tattoos will not be admitted (including fake tattoos). So depending on the size of your tattoos you may be able to get by, using  a rash guard or waterproof bandages.
