“Rumoi” (留萌市) in the title of this article is the name of the municipality in Hokkaido that accepts the donation, and it is also where the manufacturer is located, but it is not where the raw material, kazunoko (herring roe), comes from (the country of origin of the raw material is listed as Canada or the United States). This article covers “味付け数の子 500g（250g×2袋）1本物” (seasoned kazunoko, 500g, 250g × 2 packs, whole-piece) on the Rakuten Furusato Nozei (a portal for furusato nozei, the hometown tax donation program) listing. The options on the listing are shipping frequency and delivery month, and the amount is stated the same for every option. Using the listing and Rakuten customer reviews, we organized five points: amount, shelf life, ingredient labeling, suitability as a gift, and reviews.
