The experience proposed is definitely unique. My wife and I spent 4 hours in there and we left the building satisfied by it. Please beware, you'll need to buy tickets in advance as it is usually sold out. It is also not cheap, 3200 Yen (but again, worth it). If you are not adventurous, you will miss some of the experience, as some of the rooms need a bit of searching. It's a bit like a maze and it's up to you to go find the rooms. There are activities for kids as well and a few rest rooms in the exhibition. For the ladies, please note some part of the building have mirror floors. Don't go in there with a short skirt if you can.
