Sanma is a seasonal delicacy commonly known as "Pacific saury" or "mackerel pike." It is a fish that is highly sought after during the autumn months. With its distinct silver-blue body and elongated shape, Sanma is often grilled or broiled to perfection, resulting in a flavorful and tender dish. Its arrival signifies the transition into the fall season, and its taste evokes the crispness of autumn leaves and the richness of the ocean.
