Suitable as a Gift?
The Rakuten product page’s gift section shows that noshi is available (checked on 11 September 2026). However, the page says that if you order with next-day delivery (asuraku), noshi and a delivery time cannot be set. It does not confirm which noshi inscriptions can be chosen, or whether gift wrapping or message cards are available. If you are considering this as a gift, checking the following three points with the seller before purchasing can help avoid misunderstandings.
- Which noshi inscriptions (such as oseibo) you can choose, and whether gift wrapping is available (not stated on the product page)
- Since it arrives by frozen delivery, whether you can specify a date/time the recipient can receive it
- Whether the recipient has enough freezer space for the 800g total weight
The product page mentions use for gift-giving occasions such as “Ochugen (mid-year gift),” “Respect for the Aged Day,” and “Father’s Day” (Source: Rakuten Ichiba product page, accessed September 10, 2026).

Points Some Reviewers Note
Because the crab pieces are pre-cut, there tends to be variation between individual crabs, and some reviewers note that the number and size of pieces in the set they received looked different from the photos. Perceptions of quality after freezing and thawing also vary.
