From the two observatories in the Tokyo Metro Government building near Shinjuku Station you can see an amazing 360 degree view of Tokyo and it is FREE! Look at a map when you get off the train at Shinjuku to locate the TMG building – it is about four long blocks away. Once you are near the building, signs will direct you toward the elevators and there is staff at the bottom and top to assist. Depending on when you go there may be a line. My husband and I went after sunset to the North Observatory. There are windows all the way around, a little store, and a bar at the top.
After walking around to enjoy the view from each window we had a beer at the bar. The bar faces windows that overlook both Tokyo Tower and Skytree. Very romantic! On a clear day you can even see all the way to Mt. Fuji. The walk to and from the TMG building from Shinjuku Station is also fun at night. North Observatory hours: 9:30pm -10:30pm. South Observatory hours: 9:30-5:30pm. Every Monday one or the other observatory is closed. They are both closed from Dec 29th through Jan 3rd. There is a cafe in the South Observatory and a Cafe plus bar in the North Observatory. – Sarah Straus, December 2013.
