Fukuya Home-Use Mentaiko 440g (110g × 4)
Fukuya’s Home-Use Mentaiko (mentaiko: spicy salted pollock roe) comes as four 110g packs for a total of 440g, and the product is said to let you choose the spice level and color (uncolored / regular). The product name shown on Rakuten’s product page includes “博多グルメ” (Hakata Gourmet), which refers to the seller’s location (Hakata), not the origin of the ingredients. This product’s raw material origin is walleye pollock roe / Russia or the U.S., and the place of processing is not confirmed. With more choices come more questions — which spice level or color to pick, and how long it keeps once chilled — that aren’t obvious from the product name alone. This article organizes the information on the Rakuten Ichiba product page: the amount, storage method, ingredient labeling, suitability as a gift, awards, and number of reviews.
