Five Points People Often Find Confusing When Choosing
| Item to Check | For This Product | Basis |
|---|---|---|
| 1. Amount / Servings | “1.0kg以上×1肩” (1.0 kg or more, 1 cluster) is one cluster of legs. No serving size is stated. Some reviewers say a family of 4 each had one leg and were full, or that it was too much for 3 people | Product page / Rakuten Minna no Review |
| 2. Storage & Shelf Life | About 1 month at −18°C or below. Eat the same day once thawed | Product information on the product page |
| 3. Ingredients & Allergen Labeling | The ingredients list shows king crab and salt | Product information on the product page |
| 4. Suitable as a Gift? | Comes in a gift box. Noshi (gift wrapping label) is available, including with a personal or company name, as is a message noshi | Product description on the product page |
| 5. What Reviews Say | 4.41/5 (6,432 reviews). Many mention the size of the legs and how packed the meat is. Some posts say it tasted salty in some years or that thawing was tricky | Rakuten Minna no Review (accessed September 11, 2026) |
Suitable as a Gift?
It arrives in a gift box. The shop says noshi can carry a personal or company name, and a “message noshi” (15 characters × 3 lines) is also available. The page also says there is no extra shipping charge for year-end and New Year delivery (separate shipping fee for Okinawa Prefecture only; as of September 11, 2026). Reviews include posts from people who sent it to their parents’ home as oseibo (year-end gift), and from people who give it to their employees every year.
According to the product description, noshi can be chosen with inscriptions for oseibo (year-end gifts), general celebrations, uchiiwai (thank-you gifts) or ochugen (summer gifts), or left plain (checked on 11 September 2026).
Because the amount is large, it helps to check in advance that the recipient’s freezer can fit the long gift box that holds one cluster. The product page also notes that legs that have come apart may be included to make up the weight.

Points Some Reviewers Note
Some posts say it tasted saltier than in previous years. Others say thawing in the refrigerator did not finish in time, so they used a microwave, and the melting ice caused trouble. Other posts say the saltiness was just right, so impressions vary. There are 342 ratings of 1–2 stars in total.
