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.


We hope this information will be helpful.

Notes for visitors to the observation area at the Tsukiji wholesale fish market? (2017-2018)

We really don’t understand but there is a regulation, that taking photos is prohibited at a seafood wholesale market. And its visiting hours have recently changed from 10am11am) started from 15 June, 2018.

Even though cameras are forbidden as a rule, if you ask intermediate wholesalers for permission, they will gladly let you take pictures. It doesn’t seem quite right to me to have such a rule, as if it were an art museum.

We would like to thank all the intermediate wholesalers who willingly accepted me for shootings at their shops. We are praying you will carry on more thriving business.

We hope this information will be helpful.
