“大和榛原牛” (Yamato Haibara Gyu) in the product name is a brand name given by the seller, and this article does not treat it as indicating the place of origin or processing (the seller’s explanatory images state that, at its founding, livestock facilities were built in Haibara, Nara Prefecture, and that the livestock facilities were later relocated to western Kyushu; the prefecture of origin and the place of processing are not confirmed). This article covers the sukiyaki-use 800g (400g × 2) pack of sliced Shintama (round) beef sold by うし源本店 on Rakuten Ichiba. There is no capacity selection field; it comes in a single 800g size, and the page states that it is delivered by frozen delivery. Because it is hard to tell “how many servings it is” and “by when it should be eaten,” we organized the Rakuten product page, the seller’s explanatory images, and the review descriptions into five points: quantity, shelf life, ingredient labeling, suitability as a gift, and reviews.
What We Confirmed
- Quantity and a guideline for servings
- Storage method and shelf life
- Ingredients and allergen labeling
- Whether it works as a gift
- Trends in public reviews

Suitable as a Gift?
We could not find any description of noshi, packaging, or message card support on the product page. The type of noshi wording is also not confirmed. If you are considering it as a gift, checking the following with the shop before purchasing can help avoid misunderstandings (Source: Rakuten Ichiba product page, viewed October 7, 2026).
- Noshi, packaging, and message cards: no description of support found; not confirmed
- Because it is delivered by frozen delivery, whether you can specify a date and time the recipient can receive it
- Whether the recipient has freezer space for 800g (400g × 2)
Among the reviews we read, several mention sending it in place of an ochugen (mid-year gift), for a birthday, or as a get-well celebration gift. About 9 of the 59 reviews in the default order say the recipient was pleased (Source: Rakuten customer reviews, viewed October 7, 2026. This is a trend within what we read and may not reflect the product’s current state). However, those reviews do not tell us whether noshi or packaging could be added.
