Tokyo Metropolitan Government Building
Designed by the famous Japanese architect Kenzo Tange, the Tokyo Metropolitan Government Building stands at the center of the business district Nishi-Shinjuku. If it primarily contains metropolitan government’s offices, it however offers two observatories at the top of its two towers where you can admire the capital. The observatories are free of charge for everybody. The southern tower’s one includes a cafeteria and the northern tower’s one offers a gift shop.
