New Release

Rishiri Product Details

Around June to September, we use Rishiri brand sea urchin called AKARISHIRI and SHIRORISHIRI for the general sales products, that can be found throughout Toyosu fish market and all over Japan. These are used by high-end Japanese/ Sushi restaurants and Michelin-starred restaurants all over the world such as NYC, Canada, Hong Kong, and Taiwan etc…

This is the nature of Ezoba-style Uni from Hokkaido, often known as the Red Uni or the Hokkaido Rishirito Uni, often known as the White Uni. They are raised eating the highest-grade seaweed available in Japan, often given the aromatics of kelp to the Uni.

The area is known for raising the highest-grade seaweed through the minerality of the water that is washed down from the mountains of Rishirizan. Eating such high-quality kelp has raised some of the highest quality Uni in all of Hokkaido. The representative director himself will go out and see each individual Sea Urchin caught to the choose the highest quality catch.  

※We apologize for any delays or lack of stock that could potentially be caused by the circumstances that may arise from the conditions of weather and the ocean. We appreciate your patronage.
