The product name of 良肉問屋’s “霜降り特上ローススライス” (Tokujō Marbled Loin Slices) says “A5限定” (A5 only), but one of the explanatory images on the product page also shows “A4・A5ランク” (A4/A5 rank), so the grade labeling is not consistent. In this article, we organized the publicly available product information and review-site descriptions, including this difference in labeling, into five points: amount, storage method, ingredient labeling, suitability as a gift, and reviews.
What We Confirmed
- Amount and a guide to servings
- Storage method and shelf life

Ingredients and Allergen Labeling
As far as we checked, we could not find any allergen labeling on the Rakuten Ichiba product page (specifications field, product description, and explanatory images). The specifications field gives the ingredient as “黒毛和牛肉” (Kuroge Wagyu beef). The allergen labeling item is not confirmed.
If you have a food allergy, please contact the seller before purchasing, and be sure to check the labeling on the product when it arrives.

Suitable as a Gift?
The gift field (noshi, packaging, message card) on the Rakuten product page shows noshi supported, with packaging and message cards not set. An image in the product description says noshi can be prepared and asks you to write it in the remarks field when ordering. The keyword field of the product description includes the term “風呂敷” (furoshiki, a wrapping cloth) (Source: Rakuten Ichiba product page, viewed October 8, 2026).
- Types of noshi inscription: we could not confirm them (the product page has no list).
- Gift box, simple gift box, message card, and name printing: we could not confirm them on the product page.
- Delivery: the term for the temperature zone (frozen delivery) is in the keyword field, but we could not find, as the seller’s guidance, the delivery date or whether a delivery date and time can be specified on the product page (not confirmed).
- Reviews: about 25 of the first 58 reviews in the standard order said they used it as a gift. Some also said it arrived wrapped in a furoshiki or that a delivery date and time could be specified. On the other hand, 2 of the 17 one-star reviews said the noshi inscription or the addressee differed from the order. We read the first 58 in the standard order and all 17 one-star reviews, and this may not reflect the product’s current condition (Source: Rakuten customer reviews, viewed October 8, 2026).
If you plan to give it with noshi or a furoshiki, confirming in advance what you wrote in the remarks field when ordering can help avoid mix-ups. Because the storage method is frozen, it can also help to check in advance whether the recipient has freezer space and a day they can receive it.
