On Jan. 5, 2001, a 202-kg Pacific bluefin tuna sold at Tokyo's Tsukiji fish market auction for $173,000 ($860 per kilogram), making it the most expensive single fish transaction ever recorded.
That Pacific bluefin tuna, known as hon maguro (true tuna) or kuro maguro (black tuna) in Japanese, was caught in the Tsugaru Strait, a narrow and dangerous passage that separates Japan's main island of Honshu from its northern neighboring island of Hokkaido, and links the Pacific Ocean with the Japan Sea. It was landed at Oma Port on the Shimokita Peninsula, at the northern tip of Honshu. Oma is famous throughout Japan as the port of landing for the highest quality hon maguro, which is dealt almost exclusively to high-end sushi restaurants where gourmands can pay up to and over $100 for a serving of otoro, the fatty belly meat from a giant Pacific bluefin tuna — which are also known as "black diamonds" in this nation.
Because of its association with the best quality and most expensive tuna, Oma, despite being extremely remote and practically inaccessible, has become a favorite location for the Japanese film and television industries. Cooking shows and documentaries featuring Oma and hon maguro, especially in winter, are extremely popular.
