During your busy trip in Japan, you might want to take some time to relax and recharge. In this Onsen (hot spring) theme park you’ll find many different baths, 2 sauna’s, a beautiful garden with a huge foot bath filled with various stones to massage your feet (some really hurt though^^;;).
You can wear a Yukata (for free!) and enjoy the Edo style indoor hall with all kind of restaurants, a small game center, souvenir shops etc! There’s also a relax space where you can sleep or just watch television. Massages are available as well, though they’re not free.
This Onsen theme park is open 7 days a week.
Easy to reach if you’re already in Odaiba, by using their free shuttle bus service.
