This article organizes what the Rakuten Ichiba product page and Rakuten customer reviews state into five points: quantity, storage, ingredient labeling, whether it works as a gift, and reviews.
What We Confirmed

Ingredients and Allergen Labeling
The ingredient field on the product page reads as follows (source: Rakuten Ichiba product page, accessed October 11, 2026).
- Noodles: wheat flour (wheat (produced in Japan)), salt / alcohol, pH adjuster
- Dashi soy sauce (6-serving set only): soy sauce (contains wheat and soybeans) (made in Japan), mirin, salt, glucose-fructose syrup, starch syrup, sugar, mackerel flakes, bonito flakes, protein hydrolysate, kelp / seasoning (amino acids, etc.), alcohol
The product page has no separate field for allergen labeling alone. In the ingredient field, wheat is noted for the noodles, and wheat and soybeans for the dashi soy sauce. The page also says that the factory making this product also makes products containing buckwheat flour. We found no discrepancy between the ingredient field and this note. Please make the final check against the labeling on the package you receive.

We read 117 reviews in total: 58 in the default order plus 30 ★1 and 29 ★2 reviews, posted from February 2024 to October 2026, with the latest in October 2026.

Suitable as a Gift?
The product page states that noshi (gift wrapping label) is not available (source: Rakuten Ichiba product page, accessed October 11, 2026). Wrapping, message cards, and name printing are not mentioned on the product page, so they are Not confirmed. The shop’s catch copy includes the word “gift,” but because the page states that noshi is not available, this article does not describe it as supporting gift use.
- Noshi: not available (as stated on the product page)
- Delivery: because it ships by Yu-Packet (dropped into the mailbox), the arrival date and time cannot be specified. You cannot send it on the assumption of a date and time that suits the recipient
- Quantity: the page states that buying 5 or more of the same item switches delivery to a courier service. For 4 or fewer, each item is shipped separately by Yu-Packet
Among the reviews we read, 1 of the 58 in the default order said the udon was given as a present to someone who had helped them (source: Rakuten customer reviews, accessed October 11, 2026).
