What it's made of
This clam usually reaches market under its trade name, aoyagi. Its orange foot is shucked and used raw for sushi nigiri or gunkan rolls, tender with a mild sweetness. Its small adductor muscles, called kobashira, are kept separate for their grainy bite and prized for fritters or mixed rice — a clam that shows two different faces depending on which part is used. Cooking tends to shrink the foot, so it is usually kept raw.
How it's made
It burrows just under the sand of shallow beaches and is dug up by rake or dredge net. Once landed, the foot and innards are separated from the shell, and the foot is shucked and rinsed in saltwater. It is said to spoil quickly, so handling it fast before freshness slips is key to keeping its tender texture. The kobashira are sorted out and shipped apart from the foot, each headed for a different use, prized in particular as tempura filling.
Why it took this shape
A long, shallow, sandy shoreline like Kujukuri Beach is said to offer wide stretches of the soft sand this clam favors. Its habit of clustering just under the surface near the waterline is thought to be why rake-based, beach-digging-style fishing took hold as the local method. The quality of the sand itself is said to make a real difference to how efficient that fishing is, and a storm can shift where the clams cluster overnight.

- 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.

- MirugaiFormally called mirukui, this large clam is eaten for its thick siphon, which extends far beyond the shell, prized raw for a crisp bite and mild sweetness; briefly scalding the surface is said to add a toasty note.
