Sanma Pacific Saury Autumn Shio Yaki Festival

Pacific saury fishing in Sanriku Coast (Iwate) and Hokkaido — seasonal fish following cold Oyashio Current; autumn tradition documented Meiji period

Sanma (Pacific saury, Cololabis saira) is Japan's most culturally beloved autumn fish — caught in massive quantities in the seas off Sanriku Coast (Iwate) and Hokkaido during the September-October southward migration, and eaten primarily as salt-grilled shioyaki that represents one of the most quintessentially Japanese sensory experiences of autumn. The fish's exceptional fat content during autumn migration (30%+ body fat) produces dramatic flame and smoke when grilled over charcoal — the visible sizzling and char marks of well-grilled sanma are a visual and aromatic festival of the season. Sanma are traditionally grilled whole (with innards intact, or gutted depending on preference), salted heavily, and served with grated daikon, a squeeze of sudachi citrus, and soy sauce — the bitter liver offering a savory depth enjoyed by connoisseurs who eat it as a delicacy while many diners remove it. The Tokyo Meguro-ku ward holds an annual sanma matsuri (sanma festival) in September where free sanma are grilled over charcoal on the street — one of the most iconic urban food festivals in Japan. Climate change has dramatically reduced sanma catch volumes in recent decades, making the fish more expensive and seasonally precious than in living memory.

Intensely rich, oily, and deeply savory with characteristic bitter liver contrast; sudachi citrus cuts the fat with floral sharpness; charcoal smoke integrates into the fat during grilling; one of Japanese cuisine's most complete seasonal flavor experiences
