Ingredients and Allergen Labeling
The product page lists the ingredients as “king crab, salt,” but within what we could check, we did not find a dedicated allergen labeling section for specified allergens. This item is not confirmed.
Crab is one of the ingredients that must be declared under Japan’s Food Labeling Act. If you have a shellfish (crustacean) allergy, you cannot eat this product. If you want to check the additives used in processing, please contact the shop before purchasing or check the label on the product when it arrives.

The “Gift” section of the product page shows that noshi (gift wrapping label) is available, with name printing, message cards, and free messages also supported. The product description also describes the item as suitable for gifts. However, the product page does not state the type of noshi inscription (such as oseibo (year-end gift) or uchi-iwai (a return gift for a family celebration)) or the type of packaging, such as a gift box or simple gift box; this is not confirmed.
