Suitable as a Gift?

What we could confirm about noshi and wrapping from the shop’s guide image and the product name is as follows (Source: Rakuten Ichiba listing, viewed October 11, 2026).

  • Noshi (gift-wrapping label): because of the simple packaging, all noshi are said to be “strip sticker” noshi (outer noshi). The sender’s name is not printed on the noshi but written on the shipping slip. The page says Buddhist-style noshi (butsu-noshi) cannot be attached
  • Noshi inscription: the page says you choose the type during the purchase steps, but we could not read the choices from the product page: not confirmed
  • Ordering several items: when they go to a single address, the page says that, in principle, noshi is attached to only one item. If you want it attached to each item separately, the page says to contact the shop individually
  • Wrapping and gift box: the product name says it comes in a gift box. The size and specifications of the box were not found: not confirmed
  • Message card: not confirmed

Among Rakuten reviews, about 24 of the first 60 in the default order said they used it as a gift, such as for oseibo (year-end gift), and that the recipient was pleased. On the other hand, 2 reviews at 1★ said they bought several items expecting noshi on each one, but only the outer box had noshi (posted in 2019 and 2024; Source: Rakuten customer reviews, viewed October 11, 2026). Because it is a product to be stored frozen, when giving it please also check the recipient’s date and time for receiving it and their freezer space.
