For the product named "【神戸牛】 霜降り ローススライス 500g …" (opening part of the name; Kobe Gyu marbled loin slices, 500g) from Ryoniku Toiya (良肉問屋), the grade shown in the product name does not match the grade shown in the product specifications section, and the cut is also described differently in different places.

Ingredients and Allergen Labeling
Within what we could check, no allergen labeling appears on the Rakuten Ichiba product page (product specifications section, product description, and explanatory images). The product specifications section lists the ingredient as "黒毛和牛肉（神戸牛）" (Kuroge Wagyu beef (Kobe Gyu)). Allergen labeling is Not confirmed.
Note that "beef" is included among the items for which labeling is recommended under Japan's Food Labeling Act (an item treated in the same way as the specified allergens, though not itself mandatory). If you have a food allergy and plan to eat this, ask the shop before buying or check the label on the product when it arrives.

Five Things to Check Before Buying
| What to Check | For This Product | Basis |
|---|---|---|
| 1. Amount / servings | 500g. No statement of how many servings it makes appears on the product page (there is no size selection; sold as a single item) | Rakuten Ichiba product page (product specifications section, viewed October 6, 2026) |
| 2. Storage method and shelf life | Store frozen (−18°C or below); best-before is 1 month frozen. Thawing method is not confirmed (not stated on the page) | Rakuten Ichiba product page (product specifications section, viewed October 6, 2026) |
| 3. Ingredients and allergen labeling | The ingredient is Kuroge Wagyu beef (Kobe Gyu). Allergen labeling is Not confirmed (not stated on the page) | Checked the Rakuten Ichiba product page (product specifications section, product description, and explanatory images) |
| 4. Suitable as a gift? | The gift field on the Rakuten product page (noshi (gift wrapping label), wrapping, message card) has no options set. On the other hand, an explanatory image says noshi is available, and the product name mentions furoshiki (wrapping cloth). The type of inscription is not confirmed | Rakuten Ichiba product page (gift field, explanatory images, and product name, viewed October 6, 2026) |
| 5. Review trends | Rated 4.64/5 (269 reviews). We read the first 54 reviews in the standard sort order (Rakuten's default) and all 1-, 2-, and 3-star reviews (21 in total), posted from October 2022 to February 2024; the latest post is from February 2024 (0 posts within the last two years). These trends may not reflect the product's current condition. Many reviewers mention satisfaction with the taste or as a gift, while some mention toughness, slice thickness, or a gap from what they expected of the grade | Rakuten customer reviews (viewed October 6, 2026) |
Suitable as a Gift?
The information on the product page is not consistent from place to place. The gift field on the Rakuten product page (noshi, wrapping, message card) has no options set. On the other hand, an image in the product description says noshi is available and asks buyers to write their request in the remarks field when ordering. The product name mentions furoshiki (Source: Rakuten Ichiba product page, viewed October 6, 2026). We have recorded the discrepancy as it is.
- Types of noshi inscription: could not be confirmed (no list on the product page).
- Gift box, simple gift box, message card, and name printing: could not be confirmed on the product page.
- Shipping: we found no guidance on the product page about the temperature or delivery date (not confirmed).
- Reviews: several posts say it was used as a gift and the recipient was pleased. Some posts also say it arrived wrapped in a furoshiki, or that the shop accommodated a change of delivery date (Source: Rakuten customer reviews; posted 2022–2024).
If you plan to send it with noshi or furoshiki, checking what is shown when you order makes mix-ups less likely. Because the storage method is frozen, it is also reassuring to check in advance whether the recipient has freezer space and which day they can receive it.

We organized the Rakuten Ichiba product reviews by theme. The ratings are as of the viewing date and change afterward.

Gap from expectations of Kobe Gyu or the grade; variation between packs
12 of the 75 reviews we read said, in effect, that it was different from what they expected of Kobe Gyu or the grade (such as A5), or that quality varied from pack to pack (3 of the 54 in the standard sort order, 4 of the 7 two-star reviews, and 5 of the 12 three-star reviews). These range from 4-star to 2-star posts dated October 2022 to May 2023.
How to check: the grade and Kobe Beef statements are summarized in the "Grading / Certification Statements" row of this article's "Basic Information" section.
Condition on arrival
Both of the 2 one-star reviews mentioned discoloration of the meat on arrival, or many scraps and a small amount. They were posted in May and July 2023. One of the two cites delivery during a heat wave after the date was moved, and the other gives the reviewer's guess that the frozen meat may have thawed; the cause cannot be confirmed.
