Overview: Tokyo's Chuo District, facing the ocean. Roughly 4 kilometers from the harbor, spanning a tributary river flowing into Tokyo Bay, is the bridge of Nihonbashi. In the center of the bridge is the road origin marker. All the roads connecting Tokyo to cities across Japan begin here. The area around the bridge has long flourished as a center of Japanese commerce. Wonderful old culture and traditions remain in this town. This is a story of Tokyo's Nihonbashi area.
