See the whole city of Tokyo for FREE!

The Tokyo Metropolitan Government Building is the tallest building in Tokyo. It also has a FREE observation deck (two, actually) where you can get a beautiful view of all of Tokyo. It is located in Shinjuku - West Exit. Follow the signs to the building and once you're in there, you'll go to one of the elevators where there is security (they check your bags for safety reasons) and head up to the top floor. You can take photos of the view but you cannot bring tripods.
