What is it?
Uni no kaiyaki heaps raw sea-urchin roe into a large surf-clam shell and steam-roasts it in Iwaki, Fukushima. It does not cook uni in its own spiny shell; the surf-clam shell is both vessel and visual signature.
Heat firms the top while the interior may remain softer, concentrating the uni's sweetness and savoriness. It is historically tied to the early-summer and summer catch, though frozen products may circulate outside the season.
History and local context
Official Iwaki tourism describes it as an Iwaki specialty made by piling raw uni into a surf-clam shell and steam-roasting it. Some accounts mention charcoal, but producers differ in exact heating and one method should not be declared universal.
Packing uni in a shell helped consolidate and preserve a fragile catch. It differs from mixed shellfish grilling, uni miso and salted bottled uni.
How to enjoy it
Heat exactly as the product instructs, stabilize the shell on a plate and take small spoonfuls combining the firmer top and soft center with rice or sake.
Never place a souvenir or unapproved shell over direct flame. Check for sharp chips and follow chilled or frozen storage directions.
Availability varies by maker, season, and destination.
