Having heard a lot about the free observation deck at the Tokyo Metropolitan Government building not far from Shinjuku station, I decided to go and take a look for myself. Located on the 45th floor, the observation deck offers a spectacular all-around view of Tokyo on a clear day, with the chance to see Mt. Fuji in the distance. The gift shop offers a nice range of souvenirs to bring back, albeit a little on the pricey end. There's also a small cafe and vending machines for visitors to grab a drink while waiting for the sunset, which is when it starts to get a little crowded. All in all, the Tokyo Metropolitan Government Building is a great and free alternative to Tokyo Tower or Tokyo Skytree for taking in the view of Tokyo.
