This article covers a small-size wakeari (imperfect/irregular, sold at a discount) amaebi (sweet shrimp) without roe, 500g, sold on Rakuten Ichiba by the shop 越前かに問屋ますよね (Echizen Kani Donya Masuyone). The same shop also sells amaebi with roe, but that is a different product. The product page gives no reason for the wakeari label, so it is not confirmed. We organized five points—quantity, shelf life, ingredient labeling, suitability as a gift, and reviews—from the product page and publicly available reviews.
*The Amazon link goes to the same store’s item in different specifications (the Amazon listing is amaebi without roe, 500g (about 40–50 shrimp), with no small-size or wakeari label, while the Rakuten Ichiba item is a small-size wakeari item). The amount and contents in this article are based on the Rakuten Ichiba item. Please check the details on the Amazon product page before purchasing.
What We Confirmed
- Quantity and how many servings
- Storage method and shelf life
- Ingredients and allergen labeling
- Whether it works as a gift
- Trends in public reviews
Basic Information
This table transcribes what is stated on the product page. However, the “not confirmed” labels and any notes we add are our own.
| Product name | 子なし越前甘えび500g(無添加・無着色)(小サイズ)2-4人前 [訳あり] (Echizen amaebi without roe 500g, no additives, no coloring, small size, 2-4 servings, wakeari)Source: Rakuten Ichiba product page (viewed October 3, 2026). Promotional notices such as coupons and seasonal announcements are omitted from the transcription |

| Product type (name) | 越前甘えび（子なし）［訳あり品］ (Echizen amaebi, without roe, wakeari item)Source: “Product contents” section of the Rakuten Ichiba product page (viewed October 3, 2026) |
| Quantity | 500g (raw / frozen). The product description states about 50 shrimp. An image on the product page says “40〜50匹／500g” (40–50 shrimp / 500g), so the number of shrimp has a range. The product name says “2-4人前” (2–4 servings); the product description and images give no number of servingsSource: product description and image text on the Rakuten Ichiba product page |
| Size category | Small size. The size of each shrimp (cm / g) is Not confirmed. An image on the product page notes that, depending on the fishing ground and season, sizes may vary in some packsSource: product name and image notes on the Rakuten Ichiba product page |
| Reason for wakeari | Not stated on the product page: Not confirmedSource: Rakuten Ichiba product page (only the label “訳あり品” (wakeari item) appears in the product name and product contents section) |
| Form (part) | Whole shrimp with the head and shell onSource: image on the Rakuten Ichiba product page (photo of amaebi without roe) |
| Storage method | Frozen (store at −18℃ or below)Source: product description on the Rakuten Ichiba product page |
| Best-before date | Stated as within 1 month frozen (1 week recommended) and within 1 day refrigerated. The shop advises eating them as soon as possible, because home freezers keep a higher temperature than commercial ones and quality may sufferSource: product description on the Rakuten Ichiba product page |
| Origin of ingredients | Fukui (Echizen)Source: “Product contents” section of the Rakuten Ichiba product page |
| Place of processing | Not confirmed |
| Condition / how to eat (cooking needed?) | Raw / frozen. The shop explains that the shrimp are flash-frozen on board the fishing boat, and that a glaze of ice is intentionally applied to the surface to prevent freezer-drying. We could not find guidance on whether they can be eaten raw or need cooking. The product name includes the words “お刺身” (sashimi) and “海鮮丼” (seafood rice bowl), but we could not find these as the shop’s guidance on how to eat themSource: product name and image text on the Rakuten Ichiba product page |
| How to thaw | If you cannot eat them all at once, the shop says to quickly thaw only part of the pack under running water to melt the glaze of ice on the surface; the shrimp then come apart one by one, so you can take out what you need and keep the rest frozen. It also says to refrain from refreezing after fully thawing, because the flavor deteriorates. A note acknowledges the inconvenience that the shrimp are hard to thaw individuallySource: image on the Rakuten Ichiba product page |
| Shipping | Stated as eligible for “Asuraku,” Rakuten’s next-day shipping service (orders placed by 11:00). Hokkaido, Kyushu, Okinawa Prefecture, and some remote islands are excluded from Asuraku, with delivery from the 2nd day onward. The shop says time-slot delivery, noshi (gift wrapping label) settings, and bank transfer cannot be used with Asuraku. Whether it ships frozen and the carrier are Not confirmedSource: product description on the Rakuten Ichiba product page |
| Manufacturer | Not confirmed (the product page lists only the seller, 有限会社増米商店)Source: “Product contents” section of the Rakuten Ichiba product page |

Award claim stated by the shop: the product name says “グルメ大賞受賞” (Gourmet Award winner), and an image on the product page says it won in the shrimp category in 2012. According to the image’s explanation, this is the Rakuten Gourmet Award, which decides the best product in each category of Rakuten Ichiba gourmet goods based on factors such as number of reviews and sales, with a data period from January 1 to December 31, 2012. All of this is the shop’s own claim, and because it is a 2012 result it is not the latest.Source: Rakuten Ichiba product page (product name and image text, viewed October 3, 2026)
Ingredients and Allergen Labeling
We could not find the ingredient names, additives, or allergen labeling on the Rakuten Ichiba product page (product description and images). This item is Not confirmed on the Rakuten side. The shop states “無添加・無着色” (no additives, no coloring) in the product name, and an image on the product page states that no antioxidants or additives are used (both are claims by the seller).
On the other hand, the Amazon product information for the same shop’s amaebi without roe, 500g, lists ホッコクアカエビ (northern shrimp) as the ingredient and shrimp as an allergen. Because Rakuten Ichiba has no listing while Amazon lists shrimp, this article treats the product as containing shrimp. If you have a shrimp allergy, please contact the seller before purchasing or check the food label on the delivered product.

Five Things to Check Before Buying
| Item to check | For this product | Basis |
|---|---|---|
| 1. Quantity / servings | 500g (about 40–50 shrimp). The product name says 2-4人前 (2–4 servings) | Product description and image on the Rakuten Ichiba product page. The number of servings appears only in the product name |
| 2. Storage and shelf life | Frozen (−18℃ or below). Stated as within 1 month frozen (1 week recommended) and within 1 day refrigerated | Product description on the Rakuten Ichiba product page |
| 3. Ingredients and allergen labeling | Not listed on the Rakuten product page, so Not confirmed. The Amazon product information lists shrimp | Rakuten Ichiba and Amazon product pages |
| 4. Suitable as a gift? | Noshi (gift wrapping label) is shown as available (the type of inscription is not stated). Noshi settings cannot be used with Asuraku. No mention of wrapping or message cards | Rakuten Ichiba product page |
| 5. Review trends | Rated 4.6/5 on Rakuten Ichiba (7,733 reviews). Trends are summarized in the “What Public Reviews Say” section | Rakuten customer reviews (viewed October 3, 2026) |
Suitable as a Gift?
The Rakuten product page indicates that noshi (gift wrapping label) is available. However, it does not state the types of inscription (such as oseibo (year-end gift), ochugen (mid-year gift), or uchiiwai (return gift)). We could not find information on wrapping or message cards either. The product name includes words such as oseibo, ochugen, and gift, but we could not find any of these as guidance on inscriptions or wrapping.
- The shop states that with Asuraku (orders placed by 11:00), time-slot delivery and noshi settings cannot be used. If you want noshi, note that Asuraku is not available
- The product is raw / frozen, and Hokkaido, Kyushu, Okinawa Prefecture, and some remote islands are excluded from Asuraku (delivery from the 2nd day onward). You will need to check when the recipient can receive it
- The shop sells this product as a wakeari item, and the product page does not state the reason, so it is Not confirmed
What Public Reviews Say
We organized the Rakuten Ichiba product reviews by topic. Rating figures are as of the time we viewed them and will change afterward.
| Site | Rating | Reviews | Date viewed |
|---|---|---|---|
| Rakuten customer reviews (product page) | 4.6 / 5 | 7,733 | October 3, 2026 |
Rating breakdown: 5★ 5,401 / 4★ 1,775 / 3★ 393 / 2★ 98 / 1★ 66 (as shown on Rakuten Ichiba, viewed October 3, 2026)
What we read: the first 57 reviews in the default sort order (posted June 2009 to June 2026, the latest in June 2026) and 30 each filtered to 1★ and 2★ (posted June 2011 to April 2026), 117 in total. These are trends within what we read and may not reflect the current state of the product. Counts are approximate because the same review can fall under more than one topic.
What Reviewers Praise
Sweetness
About 25 of the 57 reviews in the default sort order mentioned sweetness (about 6 of them posted in the last two years). The main point is that the shrimp are springy and sweet even at a small size.
Large quantity
About 17 reviews (about 4 posted in the last two years) said the quantity was large. Looking at this alongside the figure of about 40–50 shrimp in the “Quantity” row of Basic Information gives a sense of the amount.
Texture
About 9 reviews (about 4 posted in the last two years) mentioned a springy, chewy, or smooth, melting texture.
Using the whole shrimp with the head / thawing in portions
About 10 reviews (about 2 in the last two years) said they used the heads for stock, such as in miso soup, and about 11 reviews (about 1 in the last two years) said they could thaw only the amount they needed under running water. Some reviewers said they could not thaw in portions; see also “What Reviewers Note” below.

What Reviewers Note
Fishy odor, freshness, appearance
About 19 of the 60 1★ and 2★ reviews complained about a fishy odor or freshness. About 7 of those said the shrimp were not fresh or had turned dark. These reviews were posted from 2011 to 2022, and we did not find any in the last two years (since October 2024). Separately, about 7 1★ reviews (2012 to 2022) said they were surprised by lumps on the head or by エビヤドリムシ (a parasite that lives on shrimp). We could not find any mention of this on the product page.
How to check: the shop’s best-before date and thawing guidance are transcribed in the “Best-before date” and “How to thaw” rows of “Basic Information” in this article.
Frozen together in one block, hard to use in small amounts
About 13 of the 60 1★ and 2★ reviews (and about 3 of the 57 in the default sort order) said all the shrimp were frozen into one lump and hard to take out a little at a time. These reviews were posted from 2011 to 2026, and we did not find any in the last two years.
How to check: the shop’s method of thawing only part of the pack is transcribed in the “How to thaw” row of “Basic Information” in this article.
Small and hard to peel
About 7 of the 60 1★ and 2★ reviews (about 1 in the last two years) said the shrimp were small and hard to peel. About 7 of the 57 reviews in the default sort order also said so.
How to check: the small-size label and the shop’s note in an image that sizes may vary are transcribed in the “Size category” row of “Basic Information” in this article.
