Kita Murasaki Uni is known as Japan's top quality Uni, with its being extremely plumb and large in size (around the size of your thumb) so it is much larger than any of its other Japanese counterparts and it is a lot creamier and sweeter with a light of texture that virtually melts in your mouth.
Rishiri Island, a small island off Japan's northernmost point, is well-known "Uni Heaven" with its Rishiri Uni often referred to as "Jewel of the Ocean". During peak season, almost 90% of Gokujo Uni (grade AAA) originate from this area and is one of the most sought-after items by Michelin Star restaurants worldwide.
