Image: from the product page of the Rakuten Ichiba shop “Kobe Frantz Sweets & Gifts” (神戸フランツ スイーツ&ギフト). The text in this image is what the shop placed in the image; Ochinity has not verified it. The image is a serving suggestion. We have not confirmed whether the gold spoon, the black tray and the small red box are included in the product. The number of puddings shown does not necessarily match the contents of the product (4 pieces).

The name of Kobe Mahou no Tsubo Pudding® (神戸魔法の壷プリン®) Chocolat, 4 pieces, and the shop’s name both contain the place name Kobe, but this is only part of the shop name and product name and does not indicate where the ingredients come from (the only ingredient with an origin stated is the milk, labeled “国内製造” (made in Japan)). This product is a set of four chocolate puddings, delivered frozen, sold by Kobe Frantz Sweets & Gifts (神戸フランツ スイーツ&ギフト). When choosing it as a gift, you’ll likely want to know how long it takes to thaw, that it contains egg, dairy, soy, and gelatin, and how to arrange the delivery date. In this article, we’ve organized the information published on the Rakuten Ichiba product page and shop page and on the Yahoo! Shopping and Amazon product pages, along with what Rakuten reviews say, into five points: amount, storage, ingredient labeling, suitability as a gift, and reviews.

Five Things to Check Before Buying

Point to CheckFor This ProductBasis
1. Amount / Servings 4 pieces (about 75g each) × 1 box. The number of servings is not stated. Only one specification can be selected on the product page Rakuten Ichiba product page (accessed September 29, 2026). The amount matches what is stated on the Yahoo! Shopping and Amazon product pages
2. Storage and Shelf Life Store at −10°C or below (frozen). The shop advises thawing in the refrigerator for 6 to 7 hours, then keeping it in the refrigerator after thawing and eating it within 2 days. How long it keeps when stored frozen is not confirmed Rakuten Ichiba product page (accessed September 29, 2026)
3. Ingredients and Allergen Labeling Labeled as containing egg, dairy, soy, and gelatin. Contains liquor (洋酒) Rakuten Ichiba, Yahoo! Shopping, and Amazon product pages (the listings match)
4. Suitable as a Gift? Noshi (gift wrapping label) is supported. Listed as gift box (化粧箱入り) and for gifting (贈答用). The shop states that it does not offer gift wrapping or double wrapping. Message card: not confirmed Rakuten Ichiba product page and shop page (accessed September 29, 2026)
5. What Reviews Say The Rakuten review rating is 4.47 out of 5 (179 reviews). We read the first roughly 25 reviews shown in the default “Standard” sort order (posted June 2012 to April 2026. The first post in the Standard order is from April 5, 2026; we did not check the “Newest” order, so the most recent posting date is not confirmed). This does not necessarily reflect the product’s current state. Among those we read, comments praising the combination of rich chocolate and the tartness of raspberry (framboise) and comments that it was well received as a gift stood out, while some noted that it is very sweet or rich, that the tartness does not suit them, or that it is small. The rating figures are as of the time we viewed them and will change afterward. Rakuten customer reviews (accessed September 29, 2026; about 25 reviews read)

Suitable as a Gift?

The following is what we could confirm on the Rakuten Ichiba product page and on the Rakuten Ichiba shop page “熨斗・ラッピングについて” (About noshi and wrapping) (accessed September 29, 2026).

  • Noshi: The product page states that noshi is supported. According to the shop page, noshi is applied for those who want it, and you choose it during the checkout process
  • How noshi is applied: For direct shipping, the shop states that a business-card-sized noshi sticker is attached directly to the corner of the shipping box. The styles are 結び切り (musubi-kiri, a fixed knot), 蝶結び (chō-musubi, a bow), 黒結び切り (black musubi-kiri), and 黄白結び切り (yellow-and-white musubi-kiri). For gifts you bring in person, there are noshi cards (red for celebrations, black for condolences)
  • Inscriptions: The table on the shop page lists several example inscriptions, including 内祝 (uchi-iwai, return gift), 出産内祝 (return gift for a birth), 新築内祝 (return gift for a new home), 御礼 (thanks), and 快気祝 (gift celebrating recovery from illness). It is unclear whether individual inscriptions can be chosen on this product’s order screen
  • Name printing: The shop page states that name printing is limited to the sender’s name, and company names are not accepted
  • Packaging: The specs section of the product page lists gift box (化粧箱入り) and for gifting (贈答用) as the food packaging method. The shop page states that it does not offer gift wrapping or double wrapping, and that some products use a rigid box (貼り箱) instead, but we could not find any statement about whether this product uses a rigid box. The shop also states that the box color cannot be specified
  • Carrier bag: The shop states that the original shopper (paper bag) is free only for the number of items purchased (accessed September 29, 2026; may change). The shop states that requests should be written in the notes field when ordering
  • Message card: Not confirmed

Because it arrives frozen, it is easier to avoid a mix-up if you check in advance which days the recipient can receive it. The purchase section of the Rakuten Ichiba product page shows “ご注文後5日後以降お届け” (delivery from 5 days after ordering), and there is also a confirmation field that advises choosing “指定なし” (no date specified) if you want the earliest delivery. The Yahoo! Shopping product page shows “お届け日指定可” (delivery date can be specified). Whether a delivery date can be specified should be checked before purchasing in the options in the purchase section of each page.

Many reviews mention using it as a Valentine’s Day gift or a White Day return gift, as a return gift (uchi-iwai), as a Mother’s Day gift, or as a gift for work-related occasions (Source: Rakuten customer reviews, accessed September 29, 2026; about 25 reviews read. This tendency does not necessarily reflect the product’s current state).

What Reviewers Praise

Many reviewers praise the combination of rich chocolate and the tartness of raspberry (framboise). Some describe it as refined and mature in taste, and others mention a melting texture. Many say it was well received as a gift, and some say the jar container is cute and can be reused after the pudding is finished.

What Reviewers Note

Some point out that it is very sweet or rich, that the tartness does not suit them, or that they got tired of it partway through. Some comment on the price, some say the jar is small, and some say it is closer to a cake or mousse than a pudding. One reviewer says it takes time to thaw, and that they thawed it in the refrigerator for about 6 hours and ate it the same day. Low ratings: one 1-star review and five 2-star reviews.
