Aka-Rishiri Bafun Uni Female Summer 400g

What is Aka-Rishiri SanToku Bafun Uni 400g?
Aka-Rishiri (赤利尻) is the Bafun uni (馬糞 / バフンウニ) harvested off Rishiri Island by Ichikawa Suisan — "Aka" referring to the deeper orange-yellow color of the Bafun variety. SanToku (三特) is Ichikawa's top sorting line. This 400g tray is the female lot, packed at the largest single portion offered. Each tray is hand-selected and taste-tested before shipping.

Bafun uni is smaller per piece than Murasaki and carries a deeper color and a more concentrated flavor — sweeter at the front, with the umami sitting longer on the palate. Rishiri uni feed exclusively on the kelp beds that grow around the island — the same Rishiri kombu that goes into top dashi. The summer harvest window (June through September) is when this diet shows up most directly in the flavor: the sweetness (甘味 / amami) reaches its peak and the umami runs deep. Inside Japan, summer Rishiri Bafun is the season the trade waits for, and the 400g SanToku tray is the size reserved for omakase counters and gatherings where the uni is the main course.

How to enjoy

The 400g format: Sized for a counter service, an omakase course, or a table of guests. Plan to use across the same meal — once opened, the tray is best consumed within a single sitting or split same-day.

As nigiri or sashimi: Served as-is, chilled. The Bafun's concentrated sweetness and deep umami carry the bite — no seasoning beyond a touch of fresh wasabi if anything.

Over rice (uni-don): A bed of warm rice, the uni placed generously on top (the 400g size supports a real uni-don, not a garnish), a few drops of soy and shiso or nori. Eat within minutes — the warmth opens the sweetness.

With pasta or risotto: Folded in at the end of cooking, off the heat. The 400g size covers four to six plates comfortably.

Pairing notes — Junmai daiginjo or junmai sake, dry champagne, chilled white burgundy. The Bafun's deeper sweetness and intensity sit especially well against cool junmai daiginjo or a blanc de blancs. For a 400g service, a chilled bottle across the table works best.
