With “wakeari” (imperfect/irregular, sold at a discount) off-cuts, besides the large amount of 1kg, it can be hard to tell how many servings they make, what “wakeari” actually refers to, and whether they are suitable as a gift, so shoppers often hesitate. This article organizes the publicly available product-page listing and the Rakuten Ichiba reviews for Matsusaka Gyu A5 Mega Portion 1kg (500g × 2), sold on Rakuten Ichiba by Matsusaka Gyu Mie Matsuyoshi (松阪牛 三重松良), into five points: amount, storage method, ingredient labeling, suitability as a gift, and reviews.

This product is sold as “wakeari.” According to a guidance image on the product page, the reason is that it also uses scrap trimmings that come up while making Matsusaka Gyu products and are hard to shape, and that it is cut to suit each part, so the shapes are uneven〔Source: guidance image on the product page (viewed October 7, 2026)〕. What is stated there is that the shapes are uneven; any other reason is not stated on the product page and is not confirmed.

The product name and the catchphrase include the notation “A5.” Within what we checked, we could not find the basis for the grade or an individual identification number displayed on the product page.

Text the shop placed in the image: “大満足の500g” (a very satisfying 500g), “松阪牛は旨味が濃いので少量でも大満足!” (Matsusaka Gyu is rich in umami, so even a small amount is very satisfying!) and “そんな松阪牛スライスをたっぷり盛り合わせ!” (a generous assortment of such Matsusaka Gyu slices!).

Ingredients and Allergen Labeling

Within what we checked, we could not find ingredient names, additives, or allergen labeling on the product page. This item is not confirmed.

Suitable as a Gift?

The shop description on the product page says it supports gift wrapping, noshi and message cards. However, this is the shop’s general description, and the types of noshi inscription and wrapping options for this specific product are not confirmed〔Source: product page description (viewed October 7, 2026)〕.

According to the FAQ, delivery dates can generally be specified up to 30 days ahead. The same section notes that during busy periods such as Rakuten Super SALE, Father’s Day, and year-end, shipping may be done in sequence〔Source: product page FAQ (viewed October 7, 2026)〕. Since all products are described as arriving frozen, if you are considering it as a gift, checking the following before buying can help avoid a mix-up.

  • What noshi and wrapping options are available (the types of inscription for this product are not stated on the product page)
  • Since it is delivered by frozen shipping, whether you can specify a date and time when the recipient can receive it
  • Whether the recipient has room in their freezer for 1kg (500g × 2)

Among the reviews we read, 5 of the 59 in the default sort order said they used it as a gift such as ochugen (mid-year gift) or for Father’s Day (source: Rakuten customer reviews, viewed October 7, 2026. This is a trend within the reviews we read and may not reflect the current product).

Rating breakdown: ★5 445 / ★4 158 / ★3 54 / ★2 41 / ★1 54 (as shown on Rakuten Ichiba, viewed October 7, 2026)

Range read: the first 59 in the default sort order (posted October 2024 to September 2026, the latest in September 2026) and 30 each filtered to ★1 and ★2 (posted March 2020 to May 2026), 119 in total. This is a trend within the reviews we read and may not reflect the current product. Counts are approximate figures from counting the posts we read.

What Reviewers Praise

Amount and ease of portioning

About 14 of the 59 in the default sort order mentioned the generous amount, or that it is easy to use because it is divided into two 500g packs. The number of servings varies by post: one said it was enough for sukiyaki for 5 adults, while another said 3 adults could barely finish 500g. These serving counts are reviewers’ impressions, not the seller’s guidance.

Comments on price

About 13 said they were satisfied with the price. Many said they bought it during a sale; we do not include the price details in this article.

Tenderness and taste of the meat

About 11 said the meat was tender and tasted good. Some posts said they used it for sukiyaki, nikujaga, gyudon, yaki-shabu and other dishes. Some also said the pieces were not small even though they are off-cuts.

Sweetness of the fat

About 6 said the fat was sweet and not heavy. This includes posts saying they tasted the sweetness of the meat even though there was a fair amount of fat.

What Reviewers Note

These counts are within the reviews we read after filtering to ★1 and ★2. They are not a share of all ratings; this range includes many older posts, and posts from the last 2 years were 4 at ★1 and 3 at ★2.

A lot of fat

About 44 of the 60 ★1 and ★2 reviews (about 4 of them posted in the last 2 years) mentioned points such as there being a lot of fat, or white fat packed at the bottom. Among the 59 in the default sort order, about 6 of the ★4–5 reviews also said there was quite a lot of fat. The “wakeari” explanation only covers the uneven shapes; the product page does not mention the amount of fat or variation between packs.

How to check: what is described as the “wakeari” reason is summarized below the table in “Basic Information” in this article.

Difference between the photos and the contents

About 15 (about 3 of them posted in the last 2 years) said that the top of the pack looked mostly lean but there was a lot of fat underneath, and that the contents differed from the impression of the product photos.

Toughness and sinew

About 13 (about 3 of them posted in the last 2 years) said the meat was tough or had sinew. Since this is an off-cuts product with mixed parts, this includes posts to the effect that the texture varied even within the same bag.
