Daichi Kaisenmaru is a seafood restaurant in Sapporo's Nijo Market that serves kaisendon topped with sea urchin, salmon roe, and tuna. The menu lets you choose the seafood you want, such as otoro, sea urchin, scallops, and raw shrimp. Arriving a little after 7 a.m. means eating without waiting, and with only three tables the room stays quiet. The seating is cramped, so a comfortable meal is difficult.
