This is a 500g pack of salmon roe marinated in soy sauce (ikura), sold on Rakuten Ichiba by 築地の王様. The origin/production field on the product page says Hokkaido, and the first ingredient is listed as salmon roe. This article organizes what the product page and the Rakuten customer reviews state into five points: contents, storage, ingredient labeling, suitability as a gift, and reviews. The features we could confirm on the product page are two: it comes in a single 500g size, and the page lists noshi (gift wrapping label) inscription types and a gift box.
At a Glance
Key points
- Noshi inscription types and a gift box are stated. The product description says noshi can be attached for ochugen (mid-year gift), oseibo (year-end gift), Mother’s Day, Father’s Day and so on, and also says the product comes in a gift box. Among the 5 soy-marinated ikura items with a 500g option that Ochinity features (as of October 17, 2026), this is the only one whose product page lets us confirm the noshi inscription types (weak points: the type of gift box, name printing, and message cards are not confirmed)
- Salmon roe marinated in soy sauce, one size (500g). The origin/production field says Hokkaido. There are no size options
- Rakuten rating 4.6 (268 reviews). Viewed October 17, 2026. Among the 5 items with a 500g option that we compared, it is lower than the trout roe of 港ダイニングしおそう (4.64) and equal to the trout roe of 甲羅組 (4.6)
- Storage: keep frozen, at −18℃ or below. The page says to avoid refreezing
Watch out for
- The shop does not state whether it can be eaten raw, how to thaw it, or how long it keeps after thawing, so these are not confirmed
- The reviews we read are mostly older posts (a trend within the range we read; it does not necessarily reflect the current state of the product)
Suits: people who want to give frozen ikura with known noshi inscription types as a seasonal gift, and people who can use up 500g at once

What Public Reviews Say
We organized the product reviews on Rakuten Ichiba by theme. Ratings are as of the viewing date and change afterward. What follows is a trend within the range we read and does not necessarily reflect the current state of the product.
| Site | Rating | Count | Viewed |
|---|---|---|---|
| Rakuten customer reviews (“Minna no Review”) (product page) | 4.6 / 5 | 268 reviews | October 17, 2026 |
Rating breakdown: 5 stars 192 / 4 stars 58 / 3 stars 9 / 2 stars 6 / 1 star 3 (as shown on Rakuten Ichiba, viewed October 17, 2026)
Range read: the first 60 reviews in the default order, plus all 3 one-star, all 6 two-star, and all 9 three-star reviews, 78 in total. Most of the default 60 are posts from 2010 to 2013; 7 are from the last two years (since October 2024), and the latest is from January 2026. Because older posts dominate, this does not represent recent opinion. It is a trend within the range we read and does not necessarily reflect the current state of the product.
Of the 3 one-star reviews, 1 was about a different product (crab) and 1 was favorable in content, so they are not counted in the trends. The counts below are approximate figures counted by reading the text; posts saying the reviewer has not yet eaten it and posts about delivery only are not included.
Points Reviewers Appreciated
Generous quantity, plenty to use (about 12 of the 60)
About 12 of the first 60 reviews in the default order said the quantity is generous and there is plenty to use. All of them are from 2013 or earlier; none were found among the posts from the last two years.
Seasoning and saltiness just right (about 7)
About 7 of the first 60 reviews said the seasoning or saltiness is just right and not too strong. 1 is from the last two years.
How to check: the ingredients are soy-sauce-based seasoning. The salt content is not found on the product page (not confirmed); it is summarized in “Basic Information” in this article.
Sent as a gift and well received (about 3)
About 3 of the first 60 reviews said it was sent as a gift, such as an oseibo gift, and was well received. 1 is from the last two years. The noshi and gift box details are in “Noshi / gifts” under “Basic Information”.
No fishy smell (about 2)
About 2 of the first 60 reviews said there is no fishy smell. Both are from 2012 or earlier.

Points Reviewers Were Concerned About
Grains small or uneven (4 of the 6 two-star reviews)
4 of the 6 two-star reviews said the grains are small or uneven in size. There are also 2 three-star reviews to the same effect. None were found among the posts from the last two years.
How to check: the notes on the product page say the origin and packaging may change without notice, and that the shop selects what arrives in each season. No standard for grain size is stated.
Opinions on the skin are split (hard: 2 / soft: 2)
2 reviews, 1 each at two stars and three stars, said the skin is hard and stays in the mouth. On the other hand, the first 60 also include 2 reviews saying the skin is soft, so impressions are split.
Saltiness, texture, quantity (around 3 each)
3 reviews in total at two and three stars said it is too salty or that the sticky texture was not to their liking. 3 reviews also said the quantity is too much to finish at once and wished it were divided into portions. Some reviews say it came in 2 packs, but the product page does not mention portions, so this is not confirmed. 3 reviews mentioned a price increase, 2 of them from the last two years.

Summary: Is This the One for You?
Why choose it: you want soy-marinated salmon roe in 500g, and you want a gift whose noshi inscription types are shown on the product page. If those two are your conditions, then among the 5 soy-marinated ikura items with a 500g option that Ochinity features (as of October 17, 2026), this is the only one that meets both (weak points: whether it can be eaten raw, how to thaw it, and how long it keeps after thawing are not confirmed, and the reviews we read are mostly older posts).
- Noshi is available; ochugen, oseibo, Mother’s Day and Father’s Day are written in the product description, and a gift box is also stated
- It is salmon roe marinated in soy sauce, the origin/production field says Hokkaido, and the only size is 500g. The Rakuten rating is 4.6 / 5 (268 reviews)
Other options: if you put the rating and the number of reviews first, 港ダイニングしおそう 鱒いくら醤油漬け (4.64, 3398 reviews, 250g／500g; trout roe); if you want salmon roe in 500g with many reviews, 北海道産 上級品 いくら醤油漬け 500g (4.55, 2690 reviews).
