The fin of a tuna is seen on display in the outer part of the Tsukiji fish market, the Jogai Shijo, in Tokyo January 4, 2015. The famous Tsukiji wholesale fish and seafood market, is scheduled to leave its fabled 80-year-old halls to move into bigger, more modern facilities next year ahead of the 2020 Tokyo Olympics. The outer part of the market, the Jogai Shijo, that caters to the public will stay in its old place, but critics wonder about its chances for survival without the world's biggest fish trading place at its doorsteps.
