Tokyo Metropolitan Government Building
In the area of Shinjuku, one of Tokyo's busiest areas, the city's government building is located here and, very high up, there are two towers, one northern and one southern, which offer for free, one of the best views of the city. You'll see if you prefer to go during the day or night. The truth is it is worth going to visit especially because you don't have to pay. You can't help but go see this enormous city from the heavens.
