This is a set of Onishi Foods alpha rice in 12 varieties, one pouch of each. The best-before date is stated as 5 years from the date of manufacture, but the shop explains that items several months past manufacture may arrive at the time of shipping, so it is not necessarily 5 years from the day it arrives. This article covers the “尾西食品 アルファ米12種類 コンプリートBOX” (Onishi Foods Alpha Rice 12 Varieties Complete Box) sold on Rakuten Ichiba by Anshin no Dendo Bosaikan (あんしんの殿堂 防災館), organized from the product page and public reviews around five points: amount, storage and best-before date, ingredients and allergens, suitability as a gift, and reviews.

Ingredients and Allergen Labeling
Within what we could check, the product page does not show an ingredient list, additives, or allergen labeling for the set as a whole. This item is not confirmed. The shop says that details such as ingredients and allergen information differ by flavor, and advises checking the individual product page for each one.
The number of items made without specified allergen ingredients is not described consistently across sources. In the shop’s product description images, 8 of the 12 varieties (white rice, sekihan, wakame rice, sansai okowa, kinoko rice, dry curry, plain rice porridge, and ume rice porridge) are described as products free of the 27 allergen items (specified ingredients, etc.). The kinoko rice pouch shown in the same image also appears to carry a “free of 28 items” label. On the other hand, the official news from Onishi Foods (the December 2020 renewal of kinoko rice) says that it previously sold a product free of 27 items and that the new package states “free of 28 items.” We have not confirmed which label appears on the pouches that arrive today, so this article does not state that they are free of these items.
The set includes shrimp pilaf. Shrimp is one of the specified ingredients that must be declared under Japan’s Food Labeling Act. If you have an allergy, check the individual product page for each flavor before buying, or check the label on the pouches when they arrive.

Five Things to Check Before Buying
| What to check | For this product | Basis |
|---|---|---|
| 1. Amount / number of servings | 12 varieties × 1 pouch each (12 pouches in total). The grams per pouch and the number of servings are not confirmed | Product description on the product page |
| 2. Storage method and shelf life | Store at room temperature. The best-before date is stated as 5 years from the date of manufacture, but several months have already passed by the time of shipping, and it differs by flavor | Product description on the product page |
| 3. Ingredients and allergen labeling | Labeling for the set as a whole is not confirmed. The shop’s description images and Onishi Foods’ official news do not agree on the number of items the products are free of | Product page / Onishi Foods official news (viewed October 2, 2026) |
| 4. Suitable as a gift? | Support for noshi (gift wrapping label), gift wrapping, and message cards is not described on the product page and could not be confirmed | Nothing in the gift-related fields of the product page |
| 5. Review trends | The Rakuten Ichiba rating is 4.6 / 5 (4,365 reviews). Many comments praise the taste and the fun of choosing among 12 varieties, while some 1★ and 2★ reviews point out that the best-before date of the item that arrived was shorter than 5 years. We read the first 60 reviews in the default order (October 2025 to September 2026; latest September 2026) and all 21 reviews rated 1★ or 2★, so these are trends within what we read. They may not reflect the product’s current condition | Rakuten customer reviews (viewed October 2, 2026) |
Suitable as a Gift?
On the product page, we could not confirm support for noshi (gift wrapping label), gift wrapping, or message cards. We could not confirm any mention of name printing either. What the product description mentions is a dedicated box original to the shop (Bosaikan) on which you can write the best-before date; we found no mention of a gift box or simple gift box (Source: Rakuten Ichiba product page, viewed October 2, 2026).
If you are considering it as a gift, checking the following points with the shop before purchasing helps avoid misunderstandings.
- Whether noshi is available, the types of inscription, and whether wrapping is possible (not described on the product page)
- The best-before date of what arrives has several months already elapsed at the time of shipping and differs by flavor, so how to tell the recipient about the date
- The shop states that if you order together with other products, everything is delivered in one shipment according to the item with the latest delivery information

What Reviewers Note
Items with a shorter best-before date arrive / dates vary by flavor
8 of the 21 reviews rated 1★ or 2★ said that the best-before date of the item that arrived was shorter than 5 years, or that it varied by flavor. However, only 1 of them was posted within the last 2 years (February 2026); the rest were posted between 2012 and 2014.
How to check: This point matches the shop’s statement in the “Best-Before Date” row of the basic information (several months have already passed by the time of shipping).
Texture and how the water mixes in
2 of the 21 reviews rated 1★ or 2★ said that the texture was hard, or that the water did not mix in well and it was hard to eat. Both were posted in 2022 and 2024, and none was posted within the last 2 years.

*The Amazon link goes to an item with the same manufacturer (Onishi Foods) and the same specifications (12 varieties × 1 pouch each, about 1.45kg), sold by a different store (the seller is not shown on the product page and is not confirmed). However, the Amazon ingredient field lists “田舎ごはん,” the former name of kinoko rice, and the Rakuten Ichiba item comes in a dedicated box original to Bosaikan, so the box and packaging may differ. The amount and contents in this article are based on the Rakuten Ichiba item. Please check the details and availability on the Amazon product page before purchasing.
