The terms “Sendai Gyu” (仙台牛) and “A5 grade” (a rank in Japan’s beef grading system) in this article are part of the product name, and the product page states that the country of origin of the beef is Miyagi Prefecture, Japan (the place of processing is not confirmed). “Premium” in the product name is the shop’s own name for this product and does not indicate any superiority in quality. Pre-sliced roast beef takes little effort between delivery and serving, but the product name alone does not tell you how many people 400g serves, how to thaw it, or whether a noshi (gift wrapping label) can be attached. In this article, we organized what the public product page and reviews say about the Sendai Gyu roast beef 400g sold by 肉のいとう (manufacturer: WIDEFOOD株式会社) of Sendai, Miyagi Prefecture, under five points: amount, storage, ingredient labeling, suitability as a gift, and reviews.

The amount and contents in this article are based on the Rakuten Ichiba item. Please check the details on the Amazon product page before purchasing.

Basic Information
This table transcribes what is stated on the product page. However, the “not confirmed” labels and any notes we add are our own.
| Product Name | 肉のいとう 仙台牛 A5ランク プレミアムローストビーフ 400g (Sendai Gyu A5-grade Premium roast beef, 400g) |
|---|---|
| Name | 仙台牛ローストビーフ (Sendai Gyu roast beef; a “specified heat-treated meat product,” a category under Japanese food labeling)Source: Rakuten Ichiba product page (viewed September 26, 2026) |
| Amount | 400g. The product page gives about 2–4 servings as a guideline (it does not explain how the number of servings breaks down). It says each slice is 20–30g, for 16–24 slices, and that the number of slices varies with the size of the meat. One roast beef sauce (tare; small, 20g) is includedSource: Rakuten Ichiba product page and the shop’s promotional images (viewed September 26, 2026) |
| Cut / Part | Momo (round)Source: Rakuten Ichiba product page |
| Storage Method | Frozen (−18°C or below)Source: Rakuten Ichiba product page description |
| Best-Before Date | 21 days from the date of manufacture, kept frozenSource: Rakuten Ichiba and Yahoo! Shopping product page descriptions |
| Country of Origin | Beef: Miyagi Prefecture, JapanSource: Rakuten Ichiba product page description |
| Place of Processing | Not confirmed |
| Condition / How to Eat (Whether Cooking Is Needed) | It is a specified heat-treated meat product and arrives sliced. The meat is already seasoned, and the page says it can be eaten as is after thawing. We did not find any instruction to cook it before eatingSource: Rakuten Ichiba product page description and the shop’s promotional images |
| Thawing | The page describes thawing it slowly in the refrigerator. However, the thawing time and whether thawing at room temperature is acceptable are not consistent within the product page. A note in the product description says to thaw it by leaving it in the refrigerator for about 5–6 hours, or at room temperature for about 1–2 hours. The shop’s promotional images say that thawing at room temperature or in a microwave causes drip (juices leaking out) and can lead to discoloration and other problems, and recommend thawing it in the refrigerator over about half a day to overnight. What both descriptions have in common is thawing in the refrigerator; please check the thawing method on the purchase page before buying. The page also says the meat looks slightly dark while frozen and returns to its color once thawed. How long it keeps after thawing is not confirmedSource: Rakuten Ichiba product page description and the shop’s promotional images (viewed September 26, 2026) |

Suitable as a Gift?
The gift options we could confirm on the product page are as follows (viewed September 26, 2026).
- Noshi: Available. If no preference is given, a bow-knot (chōmusubi) noshi is used; the page asks you to write in the remarks field when ordering if you want a tied-knot (musubikiri), Buddhist-style, or other type. There is no list of inscription (on noshi) types on the product page, so please check on the purchase page
- Gift wrapping: The shop’s description notes that some products cannot be given noshi or gift wrapping, and we could not confirm whether gift wrapping is available for this product
- Message cards and gift boxes: Could not be confirmed on the product page
It arrives by frozen delivery, and the best-before date is 21 days from the date of manufacture, kept frozen. Checking in advance when the recipient can receive it and whether they have room in their freezer helps avoid mix-ups.
