With a frozen hamburg steak assortment, the three varieties make the differences hard to tell, and from the product name alone it is hard to judge how many pieces are included, how long they keep, and whether noshi (gift wrapping label) can be added. In this article, we organized what the product page and the Rakuten review page state about the Tasting Premium Set from “Kanzaki Aging Beef — Kakunoshin” on Rakuten Ichiba (2 each of Kurokaku, Shirokaku, and Kinkaku hamburg steaks, plus 1 bottle of Gyusho, a fermented beef seasoning) into five points: quantity, storage method, ingredients, suitability as a gift, and reviews.
What We Confirmed
- Quantity and how many servings
- Storage method and shelf life
- Ingredients and allergen labeling
- Whether it works as a gift (noshi, cards, wrapping)
- Trends in public reviews

In the main text of the same shop’s product page, the three hamburg steaks (2 each, 6 in total) and Gyusho on its own are also presented as separate products. This article covers this set, which includes 1 bottle of Gyusho.
Ingredients and Allergen Labeling
The ingredients section of the product page lists, for all three hamburg steaks, meat, sautéed onion, binders (egg, breadcrumbs [contains wheat], milk), shio-koji, salt, spices, onion extract, and so on (Kinkaku also lists beef tallow). Gyusho is listed as fermented beef seasoning (Japanese beef, soy sauce koji [contains wheat and soybeans], rice koji), salt, sugar, starch / alcohol.
The “allergens used” field lists Kinkaku = pork, beef, egg, wheat, milk; Shirokaku = beef, pork, egg, wheat, milk; Kurokaku = beef, egg, wheat, milk. For Gyusho, this field is blank, while the ingredients section states that it contains wheat and soybeans, so the product page is inconsistent. In this article, we go with the “contains” side and treat Gyusho as having ingredients listed that contain wheat and soybeans. If you have allergies, check the latest labeling on the product page before purchasing, and also check the food information label on the product when it arrives.
The nutrition facts per bottle of Gyusho (70g) are shown as estimated values based on analysis of a sample: energy 102kcal, protein 8.8g, fat 3.3g, carbohydrates 9.2g, salt equivalent 10.6g. Nutrition facts for the hamburg steaks are not confirmed.

Suitable as a Gift?
The “noshi or card enclosure” field on the purchase screen offers the following options (checked October 5, 2026). Where we could not confirm something, we say so.
- Noshi: besides “for home use (no noshi)”, you can choose ochugen, oseibo, or plain inscriptions. Each is listed in both a bow-knot style and a tanzaku (strip) style. Name printing is shown as unavailable. Inscriptions for uchiiwai (return gifts) or other celebrations were not among the options in this field
- Message card: the options include enclosing a birthday card. We could not confirm whether other cards or messages are available
- Wrapping: the “food packaging method” in the product specifications is listed as boxed in a gift box, for gifting. We could not confirm whether it is a gift box or a simple gift box, or whether gift wrapping is available
- The page indicates support for Rakuten’s Social Gift, which lets you send a gift to someone whose address you don’t know (please check the terms of use on the purchase page)
This is a frozen-storage product. We could not confirm on the purchase screen whether a delivery date can be specified. Checking the purchase page guidance on when the recipient can receive it helps avoid missed deliveries.

What Reviewers Note
Saltiness
4 of the 60 reviews in the default order and 2 of the 7 2★ reviews felt that the Gyusho or the hamburg steaks themselves were salty (5 of these were posted in the last 2 years). Some posts said that because the flavor is strong, it was easier to eat when paired with other foods.
How to check: the labeled salt equivalent of Gyusho is summarized in this article’s “Ingredients and Allergen Labeling” section (nutrition facts for the hamburg steaks are not confirmed).
Feeling that it is expensive
4 of the 60 reviews in the default order, 1 of the 7 1★ reviews, and 1 of the 7 2★ reviews felt the price was high (4 of these were posted in the last 2 years). The 4 in the default order said it was expensive but they were satisfied with the taste.
Texture or taste not to their liking
8 of the 14 1★ and 2★ reviews said it was too soft, felt slimy, was too fatty, or the taste was not to their liking. All 8 were posted between 2019 and 2023; none appeared among the posts from the last 2 years in what we read.
How to check: the differences in the meat used in the three varieties are summarized in the “Meat in the 3 Hamburg Steaks” row of this article’s “Basic Information”.
