Uni will come fresh and should be kept in the refrigerator. You can store these trays for up to three days for sashimi use or one week for cooking preparations. We do not recommend storing in the freezer as thawing causes the pieces to liquify, but it is still usable-- so long as it's used within one month of freezing. FYI-- we love using our forgotten thawed uni for a creamy pasta sauce!


Place superfrozen product in cold water for 15 to 30 minutes, until thawed. Remove the portion from the plastic, pat dry and wrap with our white butcher paper provided. Cut and enjoy within 24 hours.

Riviera Seafood Club's Wild-Caught Uni, also known as Sea Urchin, is sustainably and responsibly wild-caught in Mexico, USA, Canada, or Japan. Uni presents a deep, rich ocean flavor and is very high in umami flavor as well; it is complemented by a delicate, creamy, and buttery texture. Our Sea Urchin is of the highest quality sashimi grade delivering an unrivaled flavor profile with a softly-sweet brine on the finish.

All orders of Wild-Caught Uni (Sea Urchin) are individually packaged and shipped using express overnight delivery. Each 100 gram tray packs 10-15 roe are hand caught by divers off the Pacific coastal waters from Canada, California and Mexico and delivered to your table in two days (one day for processing, one day for delivery). Uni is an extremely delicate seafood. In order to guarantee our freshness, each shipment is packaged securely to maintain proper temperatures. If you are intending to consume the seafood raw, do not freeze as this will ruin the integrity of the uni.We guarantee that our wild-caught uni (sea urchin) is the best quality that you can find, perfect for sushi, sashimi.

Time your defrost process to a couple of hours before your meal for the optimal outcome.

Yes and no. Yes, you can refreeze it for a future cooking preparation. No, if you plan on using it for raw preparation.

Yes! We suggest that most super-frozen products may be stored in a conventional freezer for up to 2 months upon usage.

The United States is late to the game... Many countries, including Japan, depend on this technology to assure minimal loss in quality and maximum gain in shelf life.

Always a reliable source to buy sashimi grade Uni & other cuts.
Bought the 100oz last week, it was so good, I just bought 2 more packs for this week.

Tasted fishy and made me sick.

The package arrived in good condition and nothing seemed off. I’ve had sea urchin and sashimi many times. Did not expect this to make me ill but I was sick for two days and I don’t think I could stomach sort of sashimi or sushi for quite some time. Sad because I really enjoy Japanese food.

Sickness is never acceptable at RSC! Shipment delayed by FedEx, causing spoilage. We have pursued claims with shipping courier and remedies with customer privately.

Deceitful shipping fees

I bought two items totaling $60 plus. I didn’t get to see the shipping fees until after I placed the order. Over $ 65 in shipping? That is EXTREMELY OUTRAGEOUS!! I told you initially that I will not be doing business with you again. I am also going to share my experience with your company with everyone that I know! And social media is very powerful!!!

Thank you so much for reaching out and providing us with this feedback!

As a small company, unfortunately we do not have the most competitive rates with shipping couriers such as FedEx and UPS, like bigger companies normally would. We know this is a factor for all of our customers, so we are constantly evaluating and renegotiating our rates with them as we grow our shipment quantities. In the meantime, we do offer free shipping order minimums if you ever want to share an order with friends/family. We can also separate and split the orders within the shipment if you let us know after placing your order. We do also frequently offer promotional discounts to our customers-- which you can stay in the loop on via email newsletter or on our Instagram and Facebook pages (@rivieraseafoodclub).

Please let us know if there is anything else we can help you with in the meantime!

Nice job…the uni is awesome! The packaging was a leaker tho.

Donald Shaul
Delicious and creamy uni

This hard to buy delicacy was packaged in individual trays and was the perfect accompaniment to our Mothers Day Sashimi meal

Uni for an Uni freak

I admit it. From the first moment I tasted sea urchin, in Hawaii, I was hooked. But only on absolutely fresh uni. When it’s fresh, it has no hint of bitterness and no trace of dry, crusty, chocolates color on its edges. It’s just briny, sweet, and soft like a great raw oyster. I’ve tasted Japanese uni and Santa Barbara uni at the same time. I think I prefer Santa Barbara because it seemed sweeter and fresher. But, if I were in Japan or Australia, I think I would prefer the local uni for the same reasons. Riviera’s uni meets all my criteria for uni. It is expensive, to be sure, so I must eat it less often than I would prefer. But, I will order it, again and again.

It’s expensive; I bought local whole sale sea food in San Jose 200gram cost $65 same quality.

Thank you for your feedback! It has been noted and will be shared with our quality and products team.
