Drinking by anyone under 20 is prohibited by law in Japan. Please follow the laws of your country or region. Drinking during pregnancy or while breastfeeding may affect the development of the fetus or infant. Please also do not drink before or while driving.

Can It Be Given as a Gift?
We could not find any setting for the gift items in Rakuten’s product information (noshi, noshi name inscription, wrapping, message card). The product description also had no guidance aimed at gift-giving. The type of noshi inscription and the wrapping are not confirmed (Source: Rakuten Ichiba product page, viewed October 4, 2026). If you plan to give it as a gift, checking with the shop before buying makes mix-ups less likely.
- Noshi, noshi name inscription, wrapping, message card: we could not find any setting in Rakuten’s product information
- Type of noshi inscription, gift box, name printing: we could not confirm these
Among the reviews we read, a few posts said they gave it as a gift for occasions such as a birthday or Father’s Day. All were posted in 2020 or earlier, and this comes from the reviewers; it does not indicate what the shop supports (Source: Rakuten customer reviews, viewed October 4, 2026).
It cannot be given as a gift to anyone under 20.

Points Praised
Consistent taste and easy to drink
About 22 of the 59 reviews in the default sort order said the taste is consistent, easy to drink, or tasty. Most are ★5, with a few ★4. Of these, 1 was posted in the last two years (February 2025); the rest were posted between 2013 and 2024.
Ways of drinking
About 11 of the 59 reviews in the default sort order mentioned how they mix or drink it, such as with hot water, on the rocks, or with soda. All were posted between 2014 and 2022, and none were found among the posts of the last two years. Because we could not find serving suggestions from the shop on the product page, this comes from the reviewers.

Shipping fees that differ by region
2 of the 15 reviews when filtered to ★3 mentioned that shipping fees now apply depending on the region. Both were posted in 2014, and none were found among the posts of the last two years. We do not list shipping fees in this article. Please check the link for the latest information.
Filtered to ★1 and ★2, there was only 1 review at ★1 (0 at ★2). The only viewpoint on which 2 or more reviews made the same point is the one above.
Source: Rakuten customer reviews (viewed October 4, 2026). Posts that mention only delivery, packaging, or the shop’s service are not counted as trends about the product. The 1 review at ★1 is about the shop’s service, so it is not counted as a viewpoint
