The allergen labeling is inconsistent within the product page. The ingredients field says “(contains soybeans, wheat, egg, dairy and pork as part of the ingredients)”, while the allergy information field in the same product description lists only pork. This article follows the ingredients field, which lists more items (Source: product description on the Rakuten Ichiba product page, viewed November 3, 2026). If you have an allergy, ask the seller before buying, or be sure to check the label on the product when it arrives (Reference: Consumer Affairs Agency, Japan, “About Allergen Labeling”, accessed November 3, 2026).
