As the “caviar substitute” in the product name indicates, lumpfish caviar is not sturgeon caviar itself but the salted roe of a fish called the lumpfish, packed in jars. This article organizes the publicly available product information and Rakuten reviews for the Lumpfish Caviar 150g (3 x 50g jars) sold by the Seafood Max Rakuten Ichiba store (シーフードマックス楽天市場店) into five points: amount, storage method, ingredient labeling, suitability as a gift, and reviews. It also notes that the country-of-origin labeling differs by source (Germany in the Rakuten Ichiba product name and elsewhere, Greenland origin in the guide images).
What We Confirmed
- The amount and estimated number of servings
- Storage method and shelf life
- Ingredients and allergen labeling
- Suitable as a gift?

The country-of-origin labeling does not match across sources. The Rakuten Ichiba product name and the Yahoo! Shopping country-of-origin field say Germany, while the guide image on the Rakuten Ichiba product page says Greenland origin. We have not been able to confirm whether each label refers to the country where the raw material comes from or to a country such as where it was processed, so this article writes them separately by source. Because the product page also says the manufacturer and packaging may differ by lot, if the place of origin matters to you, please ask the shop before buying or check the food information label on the product when it arrives.
Ingredients and Allergen Labeling
Within what we could check, neither the product page text on Rakuten Ichiba and Yahoo! Shopping nor the 12 guide images show ingredient names, additives, or allergen labeling. This item is not confirmed.
This product is made from fish roe. If you have an allergy to fish roe or seafood, or want to check additives such as coloring, please, on the premise that the labeling has not been confirmed, ask the shop before buying or check the food information label on the product when it arrives. Please be sure to check both the product page and the product packaging when you purchase.

Five Things to Check Before Buying
| What to check | For this product | Basis |
|---|---|---|
| 1. Amount and number of servings | 150g (50g x 3). No estimate of the number of servings is stated | Rakuten Ichiba product description and guide images |
| 2. Storage method and shelf life | Arrives by chilled delivery. The storage temperature is stated differently: 10°C or below on Rakuten Ichiba and 8°C or below on Yahoo! Shopping. The best-before date is said to be stated separately on the product | Rakuten Ichiba product description / Yahoo! Shopping product information |
| 3. Ingredients and allergen labeling | Not confirmed (not shown in the product page text or the 12 guide images). The country-of-origin labeling also differs by source (Germany / Greenland origin) | Rakuten Ichiba and Yahoo! Shopping product pages, guide images |
| 4. Suitable as a gift? | The page says noshi (gift wrapping label) are available in various types. For the types of inscription, wrapping, and message card, please check the purchase page | Rakuten Ichiba product description |
| 5. Trends in reviews | The Rakuten Ichiba rating is 4.45 / 5 (31 reviews, retrieved September 29, 2026). The following is the trend from the 30 reviews on the first page of the review page, in the order shown as “standard”; posting dates range from March 2018 to August 2026, and the newest post on the page is dated August 9, 2026. This trend does not necessarily reflect the product’s current state. Many comments praise the reasonable price, the quick delivery, and its use as a topping on crackers or cheese as a snack with alcohol, and posts saying that it is different from real caviar but tasty in its own way also stand out. A small number of comments say the taste and texture differ from caviar, or that it tastes rather salty or slightly fishy | Rakuten customer reviews (September 29, 2026) |
Suitable as a Gift?
The Rakuten Ichiba product description says that noshi are available in various types and that the product is gift-ready [Source: Rakuten Ichiba product page (viewed September 29, 2026)]. The Yahoo! Shopping product information also shows a gift-ready label.
However, we found no information on the product page about the types of noshi inscription, wrapping such as gift boxes, message cards, or name printing. Please check the purchase page. If you are considering this as a gift, checking the following with the shop before you buy can help avoid a mismatch with what the recipient expects.
- The types of noshi inscription (not stated)
- Whether gift wrapping such as a gift box can be chosen (not stated)
- Whether a message card can be included (not stated)
- Whether you can specify a delivery date and time the recipient can receive it, since it arrives by chilled delivery (Yahoo! Shopping shows that delivery-date selection is available; please check the purchase page for whether it can be specified on Rakuten Ichiba)
- Because the product page says the manufacturer and packaging may differ by lot, the jars that arrive may look different from the photos
What Public Reviews Say
We checked the rating count and average shown on the Rakuten Ichiba product page and the posts on the review page. The sort order was the one shown as “standard,” and we actually read the 30 reviews on the first page. This trend does not necessarily reflect the product’s current state. The rating figures reflect the time we viewed them and will change afterward. The guide images on the product page include a section presenting customer voices, but it was posted by the shop and is not a Rakuten review, so we have not included it in our summary of reviews.
| Site | Rating | Count | Viewed on |
