About Iki Murasaki Uni

Iki Island, Nagasaki Prefecture, has long been nationally renowned for its high-quality seafood catches. Among these, uni (sea urchin) boasts an overwhelming brand power as a specialty of Iki.

The taste of sea urchin is said to be greatly influenced by the environment in which it grows and the seaweed it feeds on. The Genkai Sea around Iki Island is where the Kuroshio and Oyashio currents meet, creating an environment where high-quality seaweed thrives. In particular, the Iki kelp that sea urchins feed on is incredibly vigorous and rich in nutrients, growing as much as 90cm in a month during its growth period, thanks to the rough waves of the Genkai Sea and the abundant sunlight. Because Iki sea urchins feed on this seaweed, they are characterized by a deep umami and richness, with a lingering aftertaste of that richness in the mouth.

Furthermore, Murasaki Uni, which lives in shallow waters, is still primarily harvested using the traditional method of free-diving by Ama divers. The harvested uni is carefully removed from the shells by hand, one by one, by the Ama divers.

The ability to eat freshly caught uni with only a small amount of salt is another attraction that can only be experienced in this region.

Murasaki Uni Zukushi Kaiseki Plan (Full-Course Purple Sea Urchin Plan)

This is a 90-day limited-time plan that allows you to fully enjoy a luxurious kaiseki course featuring Murasaki Uni.

Among the dishes, the signature dish “Kairi-yaki” – black abalone topped with a generous amount of Murasaki Uni and grilled over a shichirin (small charcoal grill) – is so popular that repeat customers come back every year just for this dish. The moment you put it in your mouth, the tender texture of the abalone and the rich, elegant sweetness of the Murasaki Uni harmonize, creating a blissful experience.

Enjoy a moment of savoring the rich blessings of Iki, with only a small amount of salt used as seasoning to bring out the full flavor of the Murasaki Uni.
