This is a 500g pack of smoked salmon trimmings (kiriotoshi; offcut slices) made from farmed salmon trout from Chile, sold by 王子サーモン, which says it makes its products at its own factory in Tomakomai, Hokkaido. The listing says it arrives by frozen delivery and should be kept in the freezer. We organized what the Rakuten product page and reviews say into five points: quantity, shelf life, ingredient labeling, gifting, and reviews. The features we could confirm on the product page are that it comes as one 500g bag, and the shop’s description that it contains many large slices.
At a Glance
Key points
- Trimmings in one 500g bag. The shop says it contains many slices that are larger than typical trimmings
- Made from farmed salmon trout from Chile. The listing says it is smoked at the company’s own factory in Tomakomai, Hokkaido
- The listing states 2 years from the production date when frozen (-18℃ or below). Because this is counted from the production date, the listing says the remaining period when it arrives may be shorter than this
- Rakuten rating 4.72 (239 reviews). Viewed October 23, 2026
Watch out for
- In the product page photos, the 500g comes in one bag. Some reviews say it is not divided into portions, so it takes some effort to divide it yourself (this is a trend within the 66 Rakuten reviews we read: the first 59 in Rakuten’s default order plus all reviews at 3★ and 2★. They were posted from October 2016 to October 2026, the latest in October 2026, and may not reflect the product’s current condition)
- Noshi (gift wrapping label) is not available. We also could not find any mention of gift wrapping or message cards
Suits: People who want to divide the 500g into portions themselves, freeze them, and use a little at a time in dishes such as salads and sandwiches

What Public Reviews Say
We organized the Rakuten Ichiba product reviews by viewpoint. The rating figures are as of the time we viewed them and may change afterward. What follows are trends within what we read and may not reflect the product’s current condition.
| Site | Rating | Reviews | Viewed |
|---|---|---|---|
| Rakuten customer reviews (product page) | 4.72 / 5 | 239 | October 23, 2026 |
Rating breakdown: 5★ 181 / 4★ 51 / 3★ 5 / 2★ 2 / 1★ 0 (as shown on Rakuten Ichiba, viewed October 23, 2026)
What we read: the first 59 reviews in Rakuten’s default order (posted November 2025 to October 2026; latest October 2026), all 2 reviews at 2★ (posted October 2016 to September 2022) and all 5 reviews at 3★ (posted January 2023 to February 2026), 66 in total. There were no reviews at 1★. These are trends within what we read and may not reflect the product’s current condition.
There are only 7 reviews at 1★ to 3★ combined, so the strength of any trend cannot be judged from the counts alone. The counts below are approximate figures we counted by reading the text, and they exclude posts only about delivery or how the shop handled things, and posts saying they had not yet eaten it.
What Reviewers Praise
Large, thick slices even as trimmings (about 22 of 59)
About 22 of the 59 reviews in the default order say that each slice is large for something labeled as trimmings, that the slices are thick, or that there are few small scraps. All of these were posted from November 2025 to October 2026.
Versatile in dishes (about 12)
About 12 of the 59 in the default order say they used it in salads, sandwiches, marinades, chirashi sushi, pies and the like (as described by the reviewers).

What Reviewers Note
Salty (5)

Arrives as one block, not divided (4)

There is also a comment that dividing it right after it arrived let the slices come apart neatly.

Summary: Is This the One for You?
Why choose it: You want to keep 500g of smoked salmon in your freezer at once, and you want fairly large slices even as trimmings. If these two conditions apply, this product fits (weak point: it arrives without being divided, so it takes some effort to divide it yourself).

- The listing says 2 years from the production date when frozen (-18℃ or below). The shop says to cut it while half-thawed, divide it into portions, and freeze them
- The Rakuten rating is 4.72 / 5 (239 reviews). About 12 of the 59 in the default order also said it is versatile in dishes (a trend within what we read)
