Japan, as an island nation, is surrounded by sea: to her east, the vast Pacific Ocean, the west, the Japan Sea and to the north, the Sea of Okhotsk. Correspondingly, Japan is blessed with a great variety of fish and marine life, large quantities of which end up on the nation’s dinner tables. Japan is also fortunate in that her islands span several climate zones. The southern Ryūkyū Islands, including Okinawa, are tropical, and are home to many varieties of reef-dwelling fish and invertebrates; the northern island of Hokkaidō, on the other hand, has a temperate climate similar to a northern European country and is famous for trout, salmon and cod fishing.
