Otaru Masazushi Ginza serves Hokkaido-style sushi that originated in Otaru, and it is on the 10th floor of the Pola Building in Ginza 1-chome. The chefs at the counter prepare Hokkaido ingredients such as sea urchin, herring, and scallops one piece at a time with an explanation, and the restaurant also offers the Otaru set and a 10-piece lunch course. There are counter seats and semi-private rooms, and if you state ingredients you cannot eat when reserving, the composition is changed; lunch takes about an hour. Each piece of sushi is small, so it falls short for diners who care about portion size.
