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 home some souvenirs you purchased in Sapporo, you can either have the store pack your purchased items in a box and arrange for shipping. You can also send it yourself via 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 if they have a box available. In some cases, cardboard boxes are readily 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, finding the right size or ones that are strong enough might be challenging.
