The “10kg (2 x 5kg bags)” in the product name is the amount for brown rice; white rice and partially milled rice are shown as less than 10kg.

The number of days from order to shipping is also not confirmedSource: Same as above |
| Storage method | The page advises keeping the rice out of direct sunlight in a cool place. For long storage, or to hold back insects and mold, it advises moving the rice to an airtight container and storing it in the refrigerator, or using the paid freshness-preserving pack. It states that with the regular pack, returns and exchanges are not possible even if insects or mold appear in unopened rice. As a guide to how long the rice keeps, an image in the product description gives about 2 to 3 weeks in summer and about 1 to 2 months in winter.

| 2. Storage method and shelf life | Keep in a cool place; for long storage, an airtight container in the refrigerator or the freshness-preserving pack is advised.

Suitable as a Gift?
The gift section of the Rakuten Ichiba product page marks noshi (gift wrapping label) and wrapping as supported. We found no statement on message cards or name printing (accessed October 2, 2026). However, we found no list of the noshi inscription options (such as uchi-iwai or Respect for the Aged Day), so the types of inscription are not confirmed. Words such as uchi-iwai, Respect for the Aged Day and oseibo appear in the keyword and occasion field, but they are only listed as keywords and cannot be read as showing which inscriptions are supported. An image in the product description shows “paid optional wrapping available,” so wrapping is offered as a paid option. Whether it is a gift box or simple wrapping is not confirmed.
If you are considering it as a gift, it helps to ask the shop about the following before buying, to avoid a mix-up.
- Types of noshi inscription (not stated on the product page)
- Form of wrapping (gift box or simple wrapping; not stated on the product page)
- Whether message cards and name printing are possible (not stated on the product page)
- Whether you can specify the delivery date (we found no statement; delivery takes from the day after shipping to 4 days after, depending on the region)
