Kamasho’s crab-shabu portions — sold on Rakuten Market as “Kamasho Tanoshii Shoku no Mise, Main Store” (釜庄 楽しい食の店【本館】) — come in several different sizes and packaging within the same shop, which can make it hard to know which one to choose. The product covered in this article lets you choose the thickness from 特大6Lサイズ(Extra-Large 6L) and 超特大7Lサイズ(Super Extra-Large 7L) — the product page’s options also include 大型5.5Lサイズ(Large 5.5L) — and it comes as a regular, tray-packed item. The same shop also sells a 5L-size version in a simple gift box, as well as a discounted (“wakeari” – imperfect/irregular, sold at a discount) item, but these are different products; here we’ve organized the amount, storage method, ingredient labeling, gift suitability, and reviews for this product specifically.
You choose the size grade on the product page. This article covers 特大6Lサイズ(Extra-Large 6L) and 超特大7Lサイズ(Super Extra-Large 7L) (the options also include 大型5.5Lサイズ(Large 5.5L)).

Basic Information
| State | This is crab that was frozen raw (uncooked) — not heat-cooked “boiled” crab. The shop’s description labels it “raw snow crab leg portions” (生ズワイ棒ポーション), and regarding how to eat it, advises that it must be cooked before eating.Source: the product page’s product description. (This note appears in a shared description section placed after the entry for 「ちょい訳あり7Lサイズ」— a separate size option meaning “slightly wakeari,” sold at a discount — and is not explicitly stated to apply to the main size grades [6L, 7L, 5.5L]. Based on the page’s layout it appears to be a shared note, but the exact scope is not confirmed.) |
|---|---|
| Product Name | Kamasho Raw Snow Crab Leg Portions, Extra-Large 6L / Super Extra-Large 7L“Extra-Large” and “Super Extra-Large” are size-grade names given by the shop, and do not indicate any ranking or superiority in quality. |
| Amount | Total weight of 500g per packSource: the product page’s food labeling section (viewed September 14, 2026) |
| Piece Count (by size) | Per 500g: 6L size — 13 pieces / 7L size — 8–10 pieces / 5.5L size — 15 piecesSource: same as above. The larger the size-grade number, the fewer pieces fit into the same 500g — but this is only a calculated estimate based on piece count, not a measured record of thickness per piece (the actual measured thickness of the legs is not confirmed). |
| Available Grades | 「特大6Lサイズ」, 「超特大7Lサイズ」, and 「大型5.5Lサイズ」— 5.5L is available only as a product-page option and is not included in the product name. The same product page also offers a 「ちょい訳あり7Lサイズ」with separate ingredients, amount, and best-before date listed. This article covers the regular 6L, 7L, and 5.5L grades; the 「ちょい訳あり7Lサイズ」option is outside its scope.Source: the product page’s food labeling section (viewed September 14, 2026). “Extra-Large,” “Super Extra-Large,” and “Large” are all size-grade names given by the shop, and do not indicate any ranking or superiority in quality. |
| Storage Method | The shop advises keeping it frozen (stored at −18°C or below).Source: the product page’s product description (as with the “State” row above, this note also appears immediately after the 「ちょい訳あり7Lサイズ」entry, and is not explicitly stated to apply to the main size grades) |
| Best-Before Date | 6L, 7L, 5.5L sizes: shipped with at least 45 days remaining (including the ship date). 「ちょい訳あり7Lサイズ」: shipped with at least 60 days remaining (including the ship date) — the number of days differs by size grade.Source: the product page’s food labeling section |
| Ingredients | Snow crab (Russia, Canada, USA, Japan [Sea of Okhotsk]), antioxidants (sulfites, sodium erythorbate)Source: same as above |
| Processing Location | Japan (Ehime Prefecture), Vietnam, ChinaSource: same as above |
| Gift Support | We confirmed a “noshi supported” label (*noshi* — a gift-wrapping label customarily added to Japanese gifts). The types of inscription, whether the noshi can be name-printed, and whether message cards are supported are not confirmed.Source: the “Gift” section of the Rakuten Market product page (viewed September 14, 2026) |
| Packaging | [Carefully Selected, Tray-Packed] = it comes packed in a tray.Source: the product page’s product name “Carefully Selected” (“厳選品”) is a name the shop gives itself; the criteria for the selection are not confirmed, so this does not indicate any superiority in quality. The same shop has a separate product page for a version packed in a simple gift box, but because the product code is different, whether the contents are the same as this product is not confirmed. |
| Seller | Kamasho Co., Ltd. (2-10 Fukumatsu, Onahama, Iwaki City, Fukushima Prefecture, Japan) / Rakuten Market shop: “Kamasho Tanoshii Shoku no Mise, Main Store” (釜庄 楽しい食の店【本館】) |

Ingredients & Allergen Labeling
The food label lists the ingredients as “Snow crab (Russia, Canada, USA, Japan [Sea of Okhotsk]), antioxidants (sulfites, sodium erythorbate).” We could not find a field specifically labeled “Allergens” corresponding to the designated allergens on the product page, so this point is not confirmed.
Crab is one of the allergens for which labeling is required under Japan’s Food Labeling Act. Because this product is snow crab itself, anyone with a crustacean/shellfish allergy cannot eat it. If you want to check the additives used in processing, such as the antioxidants, please contact the seller before purchase, or check the food information label on the product when it arrives.

5 Things to Check Before You Choose
| Item to Check | For This Product | Basis |
|---|---|---|
| 1. Amount & piece count | Total weight of 500g per pack. As a guide: 13 pieces for 6L, 8–10 for 7L (15 for 5.5L) | The product page’s food labeling section. There is no statement of how many servings this provides |
| 2. Storage & shelf life | Keep frozen at −18°C or below. Best-before date: 45+ days for 6L/7L/5.5L, 60+ days for 「ちょい訳あり7Lサイズ」(see the note on where the storage-method source appears, in Basic Information) | The product page’s product description and food labeling section |
| 3. Ingredients & allergen labeling | Snow crab and antioxidants (sulfites, sodium erythorbate). No field specifically labeled “Allergens” could be confirmed | The product page’s food labeling section |
| 4. Suitable as a gift? | “Noshi supported” label present. The type of inscription and message-card support are not confirmed | The product page’s “Gift” section |
| 5. Review trends | The Rakuten Market rating is 4.41 out of 5 (1,306 reviews). We read only the 11 reviews shown; the name of the sort order used and similar details are not confirmed | Rakuten customer reviews (“Minna no Review”) (viewed September 14, 2026) |
Suitable as a Gift?
The “Gift” section of the Rakuten Market product page shows a “noshi supported” label. However, we could not confirm on the page the types of inscription available (such as year-end gift or return-gift wording), whether the noshi can be name-printed, or whether message cards are supported. If you’re considering this as a gift, contacting the seller before ordering can help avoid misunderstandings.
The product description lists various gift-giving occasions, such as year-end gifts (*oseibo*), mid-year gifts (*ochugen*), Respect-for-the-Aged Day, birthday presents, and return gifts (*uchi-iwai*). However, this includes a list of keywords intended to make the listing easier to find in searches, so we’ve treated it separately from the actual “noshi supported” label.
- Whether noshi wrapping is supported (a “noshi supported” label is present, but the types of inscription are not listed on the product page)
- Packaging is [Carefully Selected, Tray-Packed] = a tray, not a gift box
- Since it arrives by frozen delivery, whether the recipient can specify a delivery date/time
Published Reviews
We organized this based on reviews shown on the product page. In addition to the 8 reviews shown in the default sort order, we switched to “sort by newest” and read 3 more, for 11 in total (the name of the default sort order itself could not be confirmed from the product page’s display, so this is not confirmed). Looking only at the 8 reviews in the default order, the posting dates span a wide range, from December 2009 to December 2025; switching to “sort by newest,” the most recent post we found was dated January 31, 2026. This trend does not necessarily represent the current state of the product. The rating figures are as of the time we viewed them and will change afterward.

Points of Concern
All 11 reviews we read this time were rated 4 or 5 stars, and we found no clear complaints. There are 64 reviews rated 1–2 stars in total (4.9% of all reviews), but none of these were included in what we read this time, so their content is not confirmed.
