Kubota Senju (久保田 千寿) Ginjo 1800ml is a sake (nihonshu) made by Asahi-Shuzo (朝日酒造) in Niigata Prefecture. “Ginjo” in this article is based on what the Rakuten Ichiba product page shows and on the type of Kubota Senju (ginjo) shown on Asahi-Shuzo’s official page; there is also a separate product under the same name Kubota Senju that is labeled “junmai ginjo.” Because many items are not shown on the Rakuten Ichiba product page, this article also lists what Asahi-Shuzo’s official page shows, clearly marked as “official labeling,” and organizes the quantity, ingredients and labeling, gift options, and reviews.
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. Never drink and drive.

Seller Labeling and Official Labeling
This article is based on the official labeling of the manufacturer, Asahi-Shuzo. Because this Rakuten Ichiba product page does not show the rice polishing ratio, alcohol content, sake meter value, acidity, or manufacturer, the figures in the table above are the official labeling, not what the seller’s page shows. Please check the label on the bottle you receive, along with the seller’s information, before or after purchase.
Note that on Yahoo! Shopping, the same seller has a product page that labels Kubota Senju 1800ml as junmai ginjo. The type shown differs from the Rakuten Ichiba labeling (ginjo), and we could not confirm from the seller’s pages which one reflects the current product. For this reason, this article does not include a Yahoo! Shopping purchase link.
Ingredients and Allergen Labeling
As far as we checked, we could not find the ingredient names or allergen labeling on the Rakuten Ichiba product page. Asahi-Shuzo’s official page shows the rice used (Gohyakumangoku), but we could not find any allergen labeling there. Allergen labeling is not confirmed. If you have allergy concerns, please contact the seller before purchasing or check the label on the product you receive.

However, we could not find any information on the product page about whether noshi is available, the types of inscription, wrapping, or message card options (Source: Rakuten Ichiba product page, viewed October 3, 2026). Please do not give alcohol as a gift to anyone under 20.
- Noshi: whether it is available and the types of inscription are not confirmed.

- Message card / name engraving: not confirmed.
- Asu-raku: the product name includes the word asu-raku. We could not confirm on the product page whether noshi or wrapping is available when ordering with asu-raku
Among the reviews we read, there were posts saying that noshi paper was requested but not attached (2010), that a box fee was added when wrapping was requested (2011), and that several date stickers were stuck on the box (2013). These are all old posts and may not reflect the current service (Source: Rakuten customer reviews, viewed October 3, 2026. See the reviews section below for details). If you plan to use it as a gift, please confirm noshi and wrapping options with the seller before ordering.
