Sometimes you come upon a building which, from the outside, looks nice and modern but isn't particularly standing out of its surroundings. Only after you've come inside you realize what an architectural masterpiece it is. One of such gems is the Tokyo International Forum building, of which I can't get enough of. I've already been there three times, and I hope I'll visit it again.
Entry is free, it's open till 11 p.m. or so, and when you come in the evening you can have the place almost to yourself. Just perfect.
