Sushi Ishiyama is a sushi restaurant in Ginza that serves omakase. It works with hikarimono such as kohada and mackerel, along with kanpyomaki, gyoku, and oily fish, balancing shari and neta. A chef explains the neta and cuts in Korean, so diners who do not speak Japanese can follow the course, and reservations are available. Wasabi is served in small amounts so the taste of the fish comes through first.
