Trails to Tsukiji SALMONbr Salmon is Japan's most-consumed fish. During the season in autumn, one day of salmon trade at Tsukiji can exceed 1 million dollars! In Japan, salmon is commonly eaten salted and served on rice. We visit Hokkaido, where 80 of Japan's wild salmon is caught, to learn more about the fish, go out to sea with a professional fisherman, and visit a factory where Japan's top-quality salmon roe is prepared.
