Spend a few hours here after the innovation museum and it was a top experience.
May cost a little to get in but i think it's worth it. You have to wear a kimono of which you get to choose your colour you get changed then you have the choice of a fot spa or full body spa.
the full body pools i think require you to stay seperate by gender and you go in buck naked... i was with my wife so we just stuck to the foot spa pools. They are very beautiful though and you can just wander through the rocky pool and or stop for a sit down... soooo relaxing on the feet. Make for some great photos too. There are other activities at an additional charge such as sand spa rock sauna and fish eating your feet. We went for the fish eating one which was another pretty unique experience. You could easily spend several hours here winding down after a few busy days on the Tokyo mainland.
