A short trip to Tokyo, spring 2013.
A large pedestrian overpass that encircles the entire intersection down below, at Tachikawa Station (north).
Some of the biggest intersections in Tokyo have these long, round-ish pedestrian overpasses and I do enjoy walking on them because they often offer a nice view of the intersection below but are also convenient for getting to the other side without waiting.

Tama area is the name of the western part of Tokyo Metropolis. It consists of 26 cities, 3 towns and a village. A lot of people (about 4 milion) live in a eastern half part of the area. However, there are many mountains in the western part of Tama area, and there are very little flat land. Many hiking spots are in the western area, so you can enjoy walking on the trail, camping, and so on. If you see the beautiful mountain scene, you may not believe this is also in Tokyo.
