This is frozen kurikinton (a confection of sweetened, mashed chestnut) made by ヤマツ食品 of Nakatsugawa City, Gifu Prefecture; its ingredient field gives the chestnuts as from Kumamoto, Miyazaki and Ehime Prefectures. This article covers the 1kg “gift box” (ご贈答用箱入り, item no. C-4) option on the Rakuten Ichiba product page; there is also a “home use, simple packaging” (ご自宅用簡易包装) option. It is one 1kg block, not divided into portions, and the listing says noshi (gift wrapping label) can be attached only to the gift box. Based on the Rakuten product page and reviews, we organized it under five points: contents, shelf life, ingredient labeling, suitability as a gift, and reviews.
At a Glance
Key points
- One 1kg block, not divided into portions. It comes in a flat container with guide lines marking 6 sections. The listing says the lines do not break cleanly while frozen
- The ingredients are chestnut and sugar (granulated sugar). The listing says 350–360g of sugar is added to 1kg of chestnut (栗粉), and the sugar content is about 55 degrees
- It arrives frozen, and the best-before date is shown as October 2027. After thawing, the listing says to keep it in the refrigerator and eat it within 3 days including the day of thawing
- Noshi (gift wrapping label) can be attached only to the “gift box” (ご贈答用箱入り). The listing says the inscription is specified in the order notes field
Watch out for
- 1kg is not an amount to finish in one sitting. You will need to cut it up and keep it in the freezer (if you cannot finish it after thawing, the shop advises refreezing it right away)
- The gift box is listed as costing extra. The size and material of the box are not confirmed
Suits: Someone who has freezer space for a 1kg block and wants to cut it up and eat it a little at a time, or someone who wants to send it with noshi

What Public Reviews Say
We organized the Rakuten Ichiba product reviews by topic. Rating figures are as of the time we viewed them and will change afterward. The summary below covers only the reviews we read and may not reflect the product’s current condition. The reviews on this page are a mix of posts about the gift box and the home-use simple packaging. Only a few posts carry a packaging type, so the ratings cannot be said to apply to the gift box alone.
| Site | Rating | Reviews | Date viewed |
|---|---|---|---|
| Rakuten customer reviews (product page) | 4.8 / 5 | 1,261 | October 29, 2026 |
Rating breakdown: 5★ 1,024 / 4★ 168 / 3★ 19 / 2★ 2 / 1★ 9 (as shown on Rakuten Ichiba, viewed October 29, 2026). The breakdown adds up to 1,222, which is 39 fewer than the overall count of 1,261 shown (the reason for the difference is Not confirmed).
What we read: the first 60 reviews in the default order (posted February 2005 to September 2026; the latest is September 23, 2026), plus all 9 reviews rated 1★ (posted November 2004 to September 2024) and all 2 reviews rated 2★ (posted November 2005 and December 2018), 71 in total. We did not read the 3★ reviews individually. These are trends within what we read and may not reflect the product’s current condition.
The counts below are approximate figures tallied by re-reading the review texts. Many posts are old: of the 60 in the default order, 15 were posted within the last two years (since October 29, 2024), and none of the 1★ and 2★ reviews were.
What Reviewers Praise
Chestnut flavor and chestnut-like taste (about 15 of the 60 in the default order)
About 15 of the 60 reviews in the default order said the chestnut flavor or aroma is strong, or that it tastes like chestnut itself.
Can be cut into portions and kept frozen (about 18)
About 18 of the 60 reviews in the default order said they cut it up when it arrived, wrapped the pieces in plastic wrap or put them in storage bags, froze them, and thawed only what they would eat. This is described as a way to finish 1kg with a small number of people.
Repeat purchases (about 20)
About 20 of the 60 reviews in the default order said they have bought it again and again, or buy it every year. The posts span a wide range of years, from 2005 to 2026.
Used as a gift (about 8)
About 8 of the 60 reviews in the default order said they used it as a gift: for oseibo (year-end gift), for a birthday, or for their parents’ home. Two of them, posted in 2026, are tagged with the home-use simple packaging, so they cannot be said to be from people who gave the gift box.
