What it's made of
Formally called the surf clam, it lives buried in sand in cold seas. Pale orange raw, only its foot turns a bright crimson once cooked. Its crisp bite and briny sweetness carry it beyond sushi into rice dishes and soups alike, and raw sashimi keeps that pale pre-cooked hue, letting the two colors sit side by side on the plate.
How it's made
It burrows just beneath the sandy seabed and is said to be caught by towing a toothed dredge called a getanet. After landing, the foot is typically split open, the innards removed, and the meat briefly blanched before use. Preferring cold water, it is said to firm up best, and come into season, through winter, while summer's warmer water is said to leave it thinner.
Why it took this shape
A stretch of coast like Tomakomai's, where cold currents run close to shore, is said to offer the cold sandy ground this clam favors. The clam is said to run so deep in local life there that the city named it its official fish.
Before you go
- How to shop at a supermarketHow to choose prepared foods, sashimi, and packaged sushi, when discount stickers tend to appear, region-only specialties, buying by weight, the checkout and bagging flow, and sampling etiquette at a local supermarket.
- Roadside stations, direct-sale stands, and marketsHow to enjoy buying food near where it's produced, visiting and shopping at morning markets and fish markets, what to expect at farm stands, and finding local food at roadside stations (michi-no-eki).

Dishes in the same style
- AkagaiA bivalve whose blood contains hemoglobin, tinting its flesh red. A traditional Edo-style sushi item, with a crisp bite and an iron-tinged flavor; even its frilled mantle edge is eaten, often vinegared.
- AsariA small bivalve familiar from beach clam-digging outings. Once purged of sand, it releases a strong broth in sake-steaming or miso soup, its flesh springy, best filled out just before spring spawning.
