With frozen head-on red shrimp, the product name alone doesn’t tell you how many shrimp 2kg works out to, how long you have to use them up, or how to handle the heads and the miso (the rich innards in the head). In this article, we organize what the public product page and reviews say about 魚耕 Wild Red Shrimp, Head-On, 2kg (Product of Argentina), sold by 魚耕 楽天市場店, into five points: quantity, storage method, ingredient labeling, suitability as a gift, and reviews. The most recent review was posted in December 2019, and the shop’s promotional images show a renewal notice for size and count, so we also note that the reviews may not reflect the current product.
What We Confirmed
- Quantity and roughly how many shrimp
- Storage method and shelf life

Ingredients and Allergen Labeling
The ingredients field on the product page lists “赤えび（海老）、酸化防止剤” (red shrimp (shrimp), antioxidant). We found no dedicated allergen field on the product page, and no specific substance name for the antioxidant. The substance name is not confirmed.
As the ingredient “赤えび（海老）” (red shrimp) indicates, this product is shrimp itself. Shrimp is one of the “specified raw materials” whose labeling is mandatory under Japan’s Food Labeling Act. People with a crustacean allergy cannot eat this product. If you want to confirm the substance name of the antioxidant, please contact the seller before purchasing or check the food label on the delivered product.

Suitable as a Gift?
We found no indication or option for noshi (gift wrapping paper) on the product page. The type of inscription (such as oseibo (year-end gift) or ochugen (midsummer gift)) is not confirmed. We found no mention of wrapping or message cards on the product page, and whether it comes in a gift box or a simple gift box is also not confirmed.
The shop’s promotional images explain that when buying 2 or more, you can choose packing from “まとめて梱包可（簡易包装）” (combined packing OK (simple packaging)) or “個別梱包を希望” (individual packing requested). They note that choosing simple packaging uses a box matched to the product size, so the box may differ from the sample photo on the product page, and that you should choose individual packing when dividing items up for gifts.Source: Rakuten Ichiba product page and the shop’s promotional images (viewed October 3, 2026)
If you are considering it as a gift, checking the following points before purchasing helps avoid misunderstandings.
- Since it arrives by frozen delivery, whether you can arrange a date and time the recipient can receive it
- Whether the recipient has room in their freezer for 2kg (about 50 shrimp)
- Whether the recipient is fine with head-on shrimp that need preparation such as removing the vein
