Kobe CRAB Raw Snow Crab Half Portions
“Half Portions” is a spec whose amount, and how it differs from “Full Portions,” can be hard to tell from the product name alone. This article organizes the information published on the product page for Kobe CRAB’s raw snow crab half portions, along with what is stated in Rakuten customer reviews, covering storage, ingredient labeling, suitability as a gift, and review trends. Where the product page did not let us confirm a detail — such as specific gift support — we have labeled that point “Not confirmed.”
*The Amazon link goes to the same store’s item in different specifications (Amazon: 500g; 1kg, 1.5kg and 2.1kg are separate listings, while Rakuten Ichiba lets you choose 400g, 500g, 700g or shoulder-meat-free 700g). The amount and contents in this article are based on the Rakuten Ichiba item. Please check the details on the Amazon product page before purchasing.

Ingredients & Allergen Labeling
The product page’s description lists the ingredients as “snow crab (Russia, Canada, or the United States), antioxidants (vitamin C, sodium sulfite)”Source: product page description (viewed September 13, 2026). We could not find the food information label itself (covering the specified allergens) within the description text we reviewed this time, so this point is Not confirmed.
This product is crab itself. Crab is one of the specified allergens that must be labeled under Japan’s Food Labeling Act, so anyone with a shellfish allergy cannot eat it. Please check the product page’s labeling, or the food information label on the item when it arrives, before you buy.

What Is “Half Portions”?
“Half Portions” is a product/spec name given to this item by the seller (Kobe CRAB). The product page description we reviewed this time does not give specific details about how it differs from “Full Portions” — such as how much shell is included, the amount of edible meat, or which cooking methods it suits — so this point is Not confirmed. We have avoided guessing the amount or composition from the word “Half.” If you are considering this purchase, please check the spec and amount described directly on the product page’s purchase screen.
Suitable as a Gift?
The gift section of the product page shows that noshi (a Japanese gift label) is supported. It does not, however, give specific details about the types of inscription available, whether a gift box or simple gift box is offered, or whether a message card is supported, so those three points are Not confirmed. The product name and description also include gift-related words such as chugen (mid-year gift), gift, for giving and present, but those words alone do not tell us how the inscription or packaging is handled.
If you are considering this as a gift, checking the following two points before you buy can help avoid a mismatch with what you expect.
- Which inscription types are available (mid-year gift, celebration and so on), whether a name can be added, and whether a gift box or wrapping is offered
- Since this ships by frozen delivery (Yamato Transport), whether the recipient can specify a delivery date and time
