Waku Waku Hills

Waku Waku Hills is an amazing indoor play-space for kids up to 13 years of age.  Located in Agano City, it's part of a new collection of buildings that includes a kindergarten and an elder care facility.

Waku Waku Hills opens for 90 minutes at a time, during which kids can play in the giant ball pit, run and jump on a massive inflatable trampoline, climb on the climbing wall, and enjoy a number of other areas.  After the 90 minutes, the building is closed while they set up for the next group of kids.  On weekdays there are 3 sessions a day, 10:00 to 11:30, 1:00 to 2:30, and 3:00 to 4:30, and on weekends there are 4 sessions, 9:00 to 10:30, 11:00 to 12:30, 1:00 to 2:30, and 3:00 to 4:30.

The first time you visit, it costs 200 yen per child for the membership fee, and 300 yen to play for 90 minutes.  After that it is always 300 yen, and adults are free.  There is a small area for babies to play in, and adults are welcome to join their children in the ball pit and on the climbing wall and trampoline.

When we visited, my son loved using the foam blocks to build his own "Super Mario" level on the trampoline, and my wife and I had a great time jumping in the ball pit.  This is one playground where I can say that adults will have as much fun as their kids!
