Tsukiji wholesale market, which trades in seafood and produce, covers about 22.5 hectares/56 acres with the fish market taking up the majority of the area. Built on reclaimed land in Tokyo Bay, much of the architecture dates back to its opening in 1935. The large, curved structure, which typifies the market, houses the intermediate seafood wholesalers. The auction areas are just outside that on the waterfront. Ongoing renovations have made the buildings a warren of passages and alcoves. Click on the image for a larger view.
