Useful Information for Foreign Tourists in Sapporo: Where to find cardboard boxes
Cardboard boxes can be purchased at the post office
If you want to ship souvenirs you purchased in Sapporo home, you can either have the store pack your purchased items in a box and arrange for shipping, or you can send it yourself by international mail at the post office or with another parcel delivery provider. If you need a cardboard box, we recommend using the various sizes of packaging the post office has available for its Yu-Pack service. Or, if you need a box to carry a large number of items purchased at a supermarket or drugstore, you can ask a store employee for a box. In some cases cardboard boxes are available near the register with a sign that reads “Help yourself,” and you can take a few boxes to use as necessary. However, since these are free, the size you are looking for may not be available, or the cardboard boxes may not be strong enough for your needs.
