Pre-cut snow crab saves you the work of shelling, but that also makes it harder to tell how many people the box will feed once it arrives, and whether you are meant to eat it raw as sashimi or cook it. This article organises what the Rakuten Ichiba product page and Rakuten customer reviews publish about Snow Crab Sashimi, Pre-Cut, 600g (750g total weight) from Minato Dining Shioso (港ダイニングしおそう), under five headings: amount, shelf life, ingredient labeling, whether it works as a gift, and what reviewers say. Since you choose from four types – 生食 (raw, to eat as sashimi) and ボイル (boiled), each also available as a ギフト仕様 (gift-packaging version) – it also sets out what to weigh when deciding between them.
This article covers all four types you can choose in the order form (生食 raw / ボイル boiled / 生食、ギフト仕様 raw with gift packaging / ボイル、ギフト仕様 boiled with gift packaging). There is only one weight option: 600g.

Ingredients and Allergen Labeling
The ingredients given on the product page are snow crab (from Russia, Alaska and Canada) and antioxidant (sulfites). The ingredient list states that sulfites are used as an antioxidant. If you avoid sulfites, check with the shop before buying.
Allergen labeling itself, on the other hand, was not found on the product page within what we could check. This item is not confirmed.
Note that this product is crab itself. Crab is one of the ingredients that must be declared under Japan’s Food Labeling Act. People with a shellfish allergy cannot eat it. If you want to check the additives used in processing, or the allergens listed with them, ask the shop before buying or check the food information label on the product when it arrives.

Suitable as a Gift?
Five things could be confirmed on the Rakuten Ichiba product page (all as displayed on 12 September 2026).
- noshi (gift wrapping label) is shown as available, in the gift section of the product page
- The product description states that it arrives in a dedicated gift box
- You can choose a ギフト仕様 (gift-packaging) type in the order form; one is offered for 生食 and one for ボイル
- Social gift sending (ソーシャルギフト) is supported, so you can send it without knowing the recipient’s address

What we could not confirm on the product page is which inscriptions the noshi can carry (oseibo year-end gift, ochugen mid-year gift, uchi-iwai return gift and so on) and whether a message card can be added. If you are considering it as a gift, checking these points with the shop before buying makes a mix-up less likely.
- Whether a noshi with the inscription you want can be attached
- Whether a message card can be added
- Whether you can specify a date and time the recipient can take delivery, since it ships frozen
- Whether the recipient has room in the freezer for 750g total weight

What Reviewers Praise
Posts that mention eating it raw as sashimi, and the taste when they did, stand out. Some describe sweetness in the meat, and some say they used it for kani-shabu (crab shabu-shabu) and hot pot through to zosui (rice cooked in the remaining broth) at the end. Many also value how easy it is to handle when the crab is already cut and no knife is needed.

Others say the flat parts (shoulder meat) are hard to pick the meat out of, or that they noticed a fishy smell. There are also 190 reviews at one or two stars, so impressions vary.
