Mashike Marche’s seasoned herring roe (kazunoko), “wakeari” with broken pieces, 500g is a frozen product that is described as needing no desalting and as ready to eat as is after thawing. However, the product page alone does not show how much of it is broken, how many servings it yields, or how long it keeps after thawing.

Suitable as a Gift?
The gift section of the Rakuten Ichiba product page lists noshi as supported (accessed October 1, 2026). The product description images say it is handled with sticker noshi, with the inscription chosen from two types, “お中元” and “お歳暮”, in a selection field, and any other inscription is to be entered in the remarks field. We could not confirm whether gift-box-style packaging or message cards are available.
If you’re considering this as a gift, checking the following on the product page before purchase can help avoid misunderstandings.
- Whether an inscription other than “お中元” or “お歳暮”, entered in the remarks field, will be handled as you wish (we have not been able to confirm this)
- Whether gift packaging such as a gift box is available (we have not been able to confirm this)
- Whether you can specify a date and time the recipient can receive it, since it arrives frozen (we have not been able to confirm whether this is possible)
- Whether you can let the recipient know that it needs to be thawed before eating, since thawing is described as taking about 12 hours
Among the reviews we read (the first 60 in the default order plus 19 filtered to 1★–3★, 79 in total; posted December 2021 to September 2026, latest September 2026), some posts said, in effect, that the product was used as a gift for elderly parents. This trend may not reflect the product’s current condition (Source: Rakuten customer reviews, accessed October 1, 2026).
What Public Reviews Say
We organized the Rakuten Ichiba product reviews by aspect. The rating figures are as of the time we viewed them and will change afterward.
| Site | Rating | Number of reviews | Date viewed |
|---|---|---|---|
| Rakuten customer reviews (“Minna no Review”) (product page) | 4.71 / 5 | 284 reviews | October 1, 2026 |
Rating breakdown: 5★ 226 / 4★ 39 / 3★ 15 / 2★ 2 / 1★ 2 (as shown on Rakuten Ichiba, viewed October 1, 2026)
What we read: the first 60 reviews in Rakuten’s default order (posted December 2024 to September 2026; latest September 2026), plus all reviews filtered to 1★ and 2★ (2 each, posted November 2022 to January 2024), plus all 15 reviews at 3★, which we added because 1★ and 2★ reviews are few (posted December 2021 to January 2026), 79 in total. Counts per aspect are approximate. These are trends within what we read and may not reflect the product’s current condition.
What Reviewers Praise
Texture and bite
More than ten of the 60 posts in the default order mentioned a popping, crunchy bite. There were also posts saying, in effect, that it was their first time trying frozen seasoned herring roe but the texture felt no different from the chilled kind.
Seasoning and convenience
More than ten of the 60 posts said the seasoning was just right, and fewer than ten mentioned the convenience of eating it simply by thawing, with no prep such as desalting. There was also a post, in effect, from someone who had always done everything from preparation to seasoning themselves and chose this to save the effort.
Broken pieces did not bother them
More than ten of the 60 posts said, in effect, that the “wakeari” broken pieces did not bother them for eating at home, or that it saved the trouble of cutting. One post felt that the grain size was better kept than in a wakeari product bought earlier from another shop.
Amount
About 10 of the 60 posts mentioned that the amount was generous. Many posts said, in effect, that they ate it at a New Year family gathering.

What Reviewers Note
Seasoning preferences
Posts whose views differed, saying the seasoning was strong, salty, sweet, or not flavorful enough, numbered 2 of the 60 in the default order, 2 of the 2★ reviews (both posted in January 2024 or earlier), and 3 of the 15 at 3★. The posts from the last two years are the 2 in the default order and some of the 3★ reviews. Even for the same seasoning, many felt it was just right, while how it is received varies from person to person.
Variation in texture and size
About 4 of the 19 reviews at 1★–3★ mentioned variation from grain to grain or bag to bag, such as a weak popping texture or many small broken pieces (of these, 2 from the last two years were 3★ reviews). There were no 1★ or 2★ posts from the last two years.
