The “国産 豊橋うなぎ紅白セット” (domestic Toyohashi unagi red-and-white set), sold by 株式会社夏目商店 of Toyohashi City, Aichi Prefecture, is a frozen unagi (eel) whose ingredient, Japanese eel, is labeled as from Toyohashi (豊橋産). This article covers the “large size” (labeled by the shop as large portions for 2 people): 1 whole kabayaki fillet (eel grilled with a sweet soy glaze) of 155–167 g and 1 whole shirayaki fillet (eel grilled plain, without sauce) of 155–167 g. Based on the product page and Rakuten reviews, it organizes the amount, storage, ingredient labeling, suitability as a gift and reviews in 5 points. Two features could be confirmed: you can compare kabayaki and shirayaki, one eel each, and a gift box, noshi (gift wrapping label) and wrapping paper are described as included (however, the gift section of the page shows noshi support as “none”, so the descriptions differ).
