| State / How to Eat (Whether Cooking Is Required) | The shop’s catchphrase includes the label “冷凍生餃子” (frozen raw gyoza). We could not find an explicit statement on whether cooking is required, so this is not confirmed. As a cooking method, the page describes arranging the gyoza in a frying pan while still frozen, adding 90–100ml of water, covering with a lid, and steam-frying over medium heat for 6 minutes 30 seconds, as well as a boiled-gyoza method of simmering them in a pot until they float (about 6 minutes) and are done. It also notes that times can vary depending on the cooking utensil, and that the powder on the product is starch and does not affect qualitySource: Rakuten Ichiba product page and product description image (viewed October 3, 2026) |
| Shipping | The page states that it is shipped by Yamato Transport’s Cool TA-Q-BIN (chilled/frozen delivery). As a guideline for dispatch, it shows that shipment is scheduled within 2–4 days (excluding the shop’s closed days) (as of October 3, 2026)Source: Rakuten Ichiba product page and the shop’s shipping information |

Ingredients and Allergen Labeling
The product description on the Rakuten Ichiba product page lists the ingredient names in this order: cabbage (domestic), pork, chicken, wrapper (wheat flour), pork fat, garlic chives, garlic, sesame oil, starch, sugar, salt, spices / seasoning (amino acids, etc.), and alcohol. The parentheses at the end state that it contains wheat, sesame, soybeans, pork, and chicken as part of the ingredients. The allergen field lists wheat flour, sesame, soybeans, pork, and chicken.Source: Product description on the Rakuten Ichiba product page (viewed October 3, 2026)
The soy labeling is inconsistent within the same product page. In the ingredients field of the product description image, the parentheses at the end state that it contains wheat, sesame, pork, and chicken as part of the ingredients, and soybeans are not included. The text of the product description labels soybeans as contained, while the product description image labels them as not contained. Because we have not been able to confirm which is the currently correct label, this article is written to match the side with more items (the one that includes soy). If you have a soy allergy, please check with the seller before purchasing, or check the collective food labeling on the package of the product when it arrives.Source: Product description and product description image on the Rakuten Ichiba product page (viewed October 3, 2026)
The seasoning (amino acids, etc.) and alcohol are written as they appear in the labeling.

Suitable as a Gift?
The seller states that noshi and wrapping (gift wrapping) are not supported (in the notice at the top of the product page and in the product description image). We could not confirm whether message cards or name printing are supported. The product description lists phrases that name gift occasions, but these do not indicate support for noshi labeling or wrapping. If you give it as a gift, you would need to prepare noshi or wrapping yourself.
- Noshi and wrapping: stated as not supported
- Message cards, name printing, and gift boxes: we could not confirm a description of support
- Because it arrives by frozen Cool TA-Q-BIN, you need to confirm a date and time the recipient can receive it. Whether a delivery date can be specified is not confirmed
Among the reviews we read, about 9 of the 58 in the default sort order mentioned using it as a gift that was well received. This is a trend within what we read and does not necessarily represent the product’s current state (Source: Rakuten customer reviews, viewed October 3, 2026).

Price
About 16 of the 92 reviews we read (58 in the default sort order and 34 ★1 and ★2 reviews) mentioned a price increase or a high price. Of these, 5 were posted within the last two years, all from the default sort order.
Watery or collapsed result after cooking

In addition, 5 of the 92 reviews we read (2 of them posted within the last two years) said that, because the gyoza are large, they fall apart easily when cooked from frozen, which makes them tricky to cook.

Filling mostly vegetables, with little meat presence
7 of the 92 reviews we read (4 of them posted within the last two years) said the filling is mostly vegetables with little meat presence, or that the inside feels sparse.
How to check: the fact that cabbage (domestic) is listed first among the ingredient names is covered in this article’s “Ingredients and Allergen Labeling.”
