About Kanazawa Maimon Sushi (金沢まいもん寿司)’s “wakeari” (imperfect/irregular, sold at a discount) seasoned herring roe (kazunoko) 500g: the “Kanazawa” in the shop name and product name is part of the shop’s name and does not indicate where the ingredients come from (the herring roe is labeled as from the U.S., and the place of processing as Shibetsu, Hokkaido). It is a frozen product described as needing no desalting and advised to be thawed in the refrigerator before eating, but the product page alone does not show how many servings it yields or how many days it keeps after thawing. This article organizes the product page’s information and Rakuten reviews into five points: amount, shelf life, ingredient labeling, gift suitability, and reviews.
What We Confirmed
- Approximate amount and servings
- Storage method and shelf life

Suitable as a Gift?
The product description images on the Rakuten Ichiba product page include a guide to noshi (accessed October 2, 2026). They explain that you choose from 4 types, “お中元”, “お歳暮”, “御年賀”, and “水引のみ” (mizuhiki only), in a selection field at the top of the cart, and also state that wrapping is not available and only noshi is supported, and that name printing is not supported. However, we could not confirm whether the example of the order screen shown in the image is for this product, and the Rakuten gift section does not show noshi support either, so whether noshi can actually be selected for this product is not confirmed. We also could not confirm the packaging form or whether 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 noshi can be attached, and if so which inscriptions can be chosen (we have not been able to confirm this for this product)
- Whether the guidance that wrapping is not available and only noshi is supported suits the occasion (the packaging form has not been confirmed)
- 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 thawing is needed, since it is advised to be thawed in the refrigerator before eating
Among the reviews we read (the first 60 in the default order plus all 11 at 1★ and all 5 at 2★, 76 in total; posted January 2021 to September 2026, latest September 2026), some posts said, in effect, that the product was used as a gift. This trend may not reflect the product’s current condition (Source: Rakuten customer reviews, accessed October 2, 2026).
