Seasoned herring roe (kazunoko) can differ in what is actually inside depending on the size of the roe grains and how it has been processed, so the product name alone can make it hard to tell “how many days you have to eat it” or “whether it works as a gift.” In this article, we organize publicly available product information about the 500g seasoned herring roe sold by Denshoku Co., Ltd. (株式会社伝食) of Tsuruga, Fukui Prefecture (Echizen Kani Shokunin Kouragumi), made with herring roe from the North Pacific (Canada, the U.S. (Alaska), or Russia), into five points: amount, storage method, ingredient labeling, gift suitability, and reviews. Its key features are that it is already seasoned and can be eaten as is after thawing, and that a strip-style sticker noshi (gift wrapping label) can be attached.
