List of sea urchin producers in Japan

In Japan, six types of sea urchins are caught: “Bafun uni”, “Ezobafun uni“, “Murasaki uni”, “Kitamurasaki uni”, “Aka uni”, and “Shirahige uni. At sushi restaurants, “Bafun uni” and “Ezobafun uni” are sometimes called “Aka uni (red sea urchin),” while “Murasaki uni” and “Kitamurasaki uni” are called “Shiro uni (white sea urchin). Generally, red sea urchins are considered more expensive than white sea urchins because red sea urchins are sweeter and last longer, but recently, due to the effects of sea desertification, the place of origin has become more important than the type of sea urchin.

The “Kitamurasaki uni” is distributed north of the Tohoku region and the “Murasaki uni” south of the Tohoku region, the “Ezobafun uni” north of the Tohoku region and the “Bafun uni” south of Matsushima Bay, respectively.

The “Kitamurasaki sea urchin” is distributed north of the Tohoku region and the “Murasaki sea urchin” south of the Tohoku region, the “Ezo-bafun uni” north of the Tohoku region and the “Bafun uni” south of Matsushima Bay, respectively.

“Ezobafun uni” and “Kitamurasaki uni” are caught on Rishiri Island and Rebun Island, “Bafun uni” and “Murasaki uni” on Shakotan Peninsula, “Bafun uni” on the four northern islands (Kunashiri Island, Etorofu Island, Shikotan Island and Chimai Islands) and Sakhalin Island, “Kitamurasaki uni” on Sanriku, Hakodate, Matsumae, Esashi and Okushiri Island, and others. Aka uni is caught in Yura, Karatsu, Hagi, Iki, and Amakusa. In Kagoshima and Okinawa, the word “sea urchin” refers to the “Shirahige uni”.

The price of that sea urchin has not stopped soaring. It is said that the price of sea urchin has doubled over the past few years. Combined with the weak yen, we hear that the Toyosu market is losing out to foreign sushi restaurants and other buyers. Increasing conflicts and rising sea temperatures are probably part of the reason for this. And foreigners visiting Japan are beginning to understand the deliciousness of sea urchin, so the number of foreigners who do not eat sea urchin is decreasing. The situation is such that the price of sea urchin is rising more and more.

We have made a list of sea urchin producers as far as we know. We honestly do not know how we should utilize this information, but we hope it will be useful.

Basically, even if you contact us, we are not sure if you can deal with us directly. As far as we know, for example, you would have to buy from an Intermediate wholesaler at the Toyosu market. And the ones with images are the Ita-uni (basic means of distribution are two types: on a plate and in salt water) that you often see at sushi restaurants.

Why is it that sea urchin sushi can taste bitter?

What does sea urchin sushi taste like?! 

Some people say that “Sea urchin in a wooden box (called ‘hako-uni’ or ‘ori-uni’ or ‘boxed sea urchin’) has a bitter medicine taste”. When a sea urchin loses its freshness, it starts to disintegrate so an additive called alum is used to maintain its shape. If you’ve ever tried a sea urchin that tasted bitter*, this may be the reason.


What is saltwater sea urchin?

Sea urchin soaked in brine without using alum (called ‘ensui-uni’ or ‘saltwater sea urchin’) is also commonly found. There is also a new technology that doesn’t use alum. In this method nitrogen water (water from which oxygen has been removed and then nitrogen dissolved) is used when sealing. The effect of replacing oxygen with nitrogen is inhibited oxidation, maintaining the freshness of the sea urchin.

*An “off flavor” that takes away from the primary good tastes.
