This article covers a thank-you gift offered through furusato nozei (hometown tax donation program) by Kesennuma City, Miyagi Prefecture. Kesennuma City is the municipality that accepts the donation and the place name listed on the product page as the place of processing; it is not where the raw ingredient comes from (the country of origin of the raw ingredient is listed as Russia). Boiled king crab legs come with many size and shipping-time options, and the donation amount changes with the size, so they can be hard to choose between. For the boiled king crab legs (本タラバガニ脚 ボイル済) offered by 株式会社カネダイ (Kanedai Co., Ltd.), this article organizes the product page and Rakuten customer reviews (“Minna no Review”) into five points: contents, shelf life, ingredient labeling, suitability as a gift, and reviews.

The number of servings is not confirmed. For size 6L, because individual crabs vary a lot in size, the legs are weighed and packed by weight, so the box may hold fewer legs than one “cluster” (kata, the unit for king crab legs: the whole group of legs attached to one shoulder of the crab), or may include broken pieces added to adjust the weight, according to the product pageSource: product description on the product page
What changes depending on your selectionSize (5L, 6L, 7L) and shipping time. The product page describes the contents as one cluster of king crab leg meat (about one cluster for 6L) from a crab that, as a whole crab, would be equivalent to 3kg for 5L, 4kg for 6L, and 4.5kg for 7L.

Ingredients and Allergen Labeling

According to the product page, the ingredients are “ボイルたらばがに(ロシア産)/調味料(アミノ酸)” (boiled king crab (from Russia) / seasoning (amino acids)), and the allergen labeling (specified ingredient) is “かに” (crab). No inconsistency in the labeling was found within the product page.

Crab is one of the specified ingredients that must be declared under Japan’s Food Labeling Act. Because this thank-you gift is crab itself, people with a shellfish allergy cannot eat it. If you are concerned about other allergies or want to check additives used in processing, ask the providing business before you apply for the donation, or check the food information label on the product when it arrives.

Suitable as a Gift?

The product page does not show any guidance on support for noshi inscriptions, gift wrapping, message cards, or name printing. The product name and keyword fields list gift-related words, but these are search keywords placed in a row, not text explaining that noshi or wrapping are supported. If you are considering it as a gift, checking the following before you apply for the donation helps avoid mix-ups.

  • Whether noshi and wrapping are supported (not stated on the product page)
  • The page says a delivery date cannot be specified (the shipping time is chosen by month)
  • If there are days you will be away, the page says to write this in the remarks field when applying, or to contact the inquiry desk within 3 days after applying
  • If delivery fails because of the recipient’s circumstances, such as a long absence, the page says redelivery and cancellation are not possible
  • Whether you have enough freezer space for a frozen item with a gross weight of 1kg–1.5kg
