日本一こだわり卵 30個 (eggs, 30 count), sold on Rakuten Ichiba by こだわり卵のsailor, delivers MS-size eggs in 3 packs of 10, and the product page fields label them as 生食用 (for eating raw). If you are choosing them to use for tamago kake gohan (rice topped with a raw egg), it is easier to decide once you have checked the best-before category and storage method, how to prepare for cracked eggs on arrival, and how noshi (gift wrapping label) is handled if you send them as a gift. Based on the Rakuten Ichiba product page, the shop’s company information page and Rakuten customer reviews, this article organizes five points: the number of eggs, storage and shelf life, ingredient labeling, suitability as a gift, and reviews.

Ingredients and Allergen Labeling

In the product page fields, the name is shown as 鶏卵 (chicken eggs). Within what we could check, the product page has no field for an ingredient list or allergen labeling, so this item is not confirmed.

Eggs are one of the specified ingredients that must be declared under Japan’s Food Labeling Act. If, for example, someone with an egg allergy will eat them, be sure to ask the shop before buying or check the label on the product when it arrives.

5. Trends in reviews The Rakuten rating is 4.72 / 5 (346 reviews). We read the first 60 reviews in Rakuten’s default order plus 12 filtered to 1★ and 2★ (posted May 2011 to October 2026; latest October 2026; of the 72 we read, 42 were posted within the last two years). The following are trends within what we read and may not reflect the product’s current condition. Many reviews mention the rich yolk and flavor or eating the eggs as tamago kake gohan, while some mention cracked eggs on arrival or freshness (none of these are among the posts from the last two years) Rakuten customer reviews (viewed October 13, 2026)

Suitable as a Gift?

The “ギフト対応” (gift options) field on the product page shows that noshi is available. The shop’s company information page lists inscriptions such as 御歳暮 (year-end gift), 御中元 (mid-year gift), 御礼 (thanks), 粗品 (small gift), 無地 (plain), 御祝 (celebration), 内祝 (return gift), 御年賀 (New Year’s greeting), 御見舞 (get-well), 快気祝 (recovery celebration), 暑中御見舞 (summer greeting), 寒中御見舞 (winter greeting), 残暑御見舞 (late-summer greeting), 御供 (offering) and 粗供養 (memorial return gift), and says name printing is also available. The shop says the noshi is attached to a product leaflet that shows no price (Source: Rakuten Ichiba product page and the shop’s company information page, viewed October 13, 2026).

We could not confirm support for gift boxes, gift wrapping or message cards on the product page. Also, the shop says that multiple boxes ordered to the same address arrive one box at a time, separately, so if you send a larger quantity as a gift, it is reassuring to check that the recipient can receive several parcels.

These are trends within what we read and may not reflect the product’s current condition, but among the reviews we read, 7 of the first 60 in Rakuten’s default order said they sent the eggs as an ochugen or oseibo gift, or that the eggs were well received as a gift (Source: Rakuten customer reviews, viewed October 13, 2026).
