This is Nihonbashi, the name of bridge. "Nihon" means Japan and "Bashi" means bridge so the name means "Japan bridge" in English.
Nihonbashi used to be the center of Tokyo during Edo period and is the beginning of the road to Kyoto, Tokaido, and because of such milestone, Mitsukoshi and Takashimaya, the most established department stores in Japan, are near the bridge.
Now this stone-made bridge is covered with the expressways, encompassing the entire Tokyo like the web. Every time I pass througth the bridge, I feel the bridge seem to need the sunlight.
