Japanese Ika Sōmen Squid Noodles and Raw Squid Craft

Japan — Hokkaido (Hakodate) and Sea of Japan coast; associated with surume ika harvest season (July–October); part of ikizukuri live seafood tradition

Ika sōmen (いかそうめん) — squid cut into noodle-like strips — is a knife technique and preparation unique to Japanese raw seafood culture, particularly associated with Hokkaido (Hakodate) and the Sea of Japan coast. The fresh squid (typically surume ika — Japanese common squid, Todarodes pacificus) is cleaned, the transparent body tube is opened flat, and the inner membrane is peeled away to reveal the pure white mantle. The mantle is then cut into very thin strips (1–2mm wide, matching the diameter of sōmen noodles) using a long, sharp yanagiba or sashimi knife. The cuts are made with the grain of the squid's muscle fibres — along the length of the mantle — for a tender, supple result. Cross-grain cuts produce rubbery, chewy strips. The resulting strips are served cold over ice or on a chilled plate, with the squid's own viscera (specifically the ink sac and liver, prepared as a sauce) or with shredded shiso and grated ginger and soy sauce. The preparation requires live or extremely fresh squid — Hokkaido's ikizukuri (live seafood) culture makes ika sōmen one of the most vivid expressions of Japan's freshness obsession.

Sweet, clean, oceanic, slightly mineral; raw squid has a delicate textural snap when correctly cut with the grain; the liver sauce adds intense umami depth and funkiness against the clean squid body
