Ingredients & Allergen Labeling
The food labeling lists the ingredients as “snow crab (Russia, Canada, USA), antioxidants (sulfites, sodium erythorbate).” It also carries the note: “The factory that makes this product also makes products that use wheat and shrimp.”
This product is crab itself, so people with a crustacean allergy cannot eat it. “Crab,” “shrimp,” and “wheat” are all specified ingredients that must be labeled under Japan’s Food Labeling Act, and the same factory also handles shrimp and wheat. If you have a shrimp or wheat allergy, please also check the food labeling on the product page before purchasing.

Five Points People Often Find Confusing When Choosing
| Item to Check | For This Product | Basis |
|---|---|---|
| 1. Amount / Servings | 5L is approx. 1kg, 30 pieces total. No serving size is stated. Some reviewers say it was plenty for 3 people or enough to satisfy 5 adults | Product page / Rakuten Minna no Review |
| 2. Storage & Shelf Life | Keep frozen (−18°C or below). Items ship with a best-before date at least 60 days away, counting the shipping date | Food labeling on the product page |
| 3. Ingredients & Allergen Labeling | Snow crab, antioxidants. The same factory also makes products with wheat and shrimp | Food labeling on the product page |
| 4. Suitable as a Gift? | Comes in a simple gift box. Noshi available (Rakuten listing); inscription types not confirmed | Product name, description and gift section on the product page (checked on 11 September 2026) |
| 5. What Reviews Say | 4.49/5 (3,384 reviews). Many mention the size and how satisfying it is to eat. Some posts say the size was smaller than expected or that thawing took a long time | Rakuten Minna no Review (accessed September 11, 2026) |
Suitable as a Gift?
The product name says it comes “in a simple gift box.” The gift section of the Rakuten product page shows that noshi is available (checked on 11 September 2026). It does not confirm which inscriptions can be chosen, or whether message cards are available. If you need a specific inscription, please ask the shop before ordering.
Another thing to keep in mind is the effort of thawing. The shop recommends half-thawing under running water, and some reviews say this took a long time. Before sending it as a gift, it helps to check whether the recipient plans to eat it right away.

Points Some Reviewers Note
Some reviewers say that even after choosing 7L, it did not feel as large as they expected. Others say thawing under running water took a long time, so they changed methods partway through. There are 181 ratings of 1–2 stars in total.
