Sushi Kotoku is a fully reservation-only sushi restaurant in Fukuoka that serves aged fish and original nigiri. It uses ingredients brought in from across the country for kaiware and vegetable nigiri, and carries a wide range of sake. Seating is centered on a counter of about seven seats, so reservations are required, and the chef shows photos of the fish while explaining each name and cut. Prices are high and portions tend to be small.
