Sushi Himitsu is a sushi restaurant in Akasaka that serves an omakase course. The course includes high-grade fish and sushi of hairtail, squid, and horse mackerel, and the shari is made with large grains of rice and carries a barley-like aroma. The chef and staff explain the course and menu in English, so diners can eat without knowing Japanese. The dining space is quiet and has few tables.
