Ask at the hotel front desk whether they can send a YAMATO domestic parcel.
Request a Kuroneko delivery form from the hotel.
Write the PotatoShip Japan warehouse address and your PotatoShip ID on the form.
Hand the parcel to the hotel staff. They will measure the size and tell you the local shipping cost.
Pay the domestic shipping fee and continue enjoying your trip.

Best for: travellers whose luggage is already full, who want to deal with everything back at the hotel, and who need to clear out a large amount of shopping in one go.

Method 2 | Send from a Department Store or Shop: The Most Direct Option

Many large department stores in Japan can help send your purchases directly to a domestic Japanese address on the spot.

Some department stores offer this after purchases over around JPY 1,000.
Once the goods are basically packed, staff can help send them by Kuroneko to any Japanese address, including the PotatoShip warehouse.

Steps

Finish shopping.
Ask the staff whether they provide Takkyubin delivery service.
Take the Kuroneko form and fill in the PotatoShip Japan warehouse address plus your PotatoShip ID.
Pay the local delivery fee.
The parcel is handed over and sent out by the store immediately.

Best for: people who want to shop and send items out immediately instead of carrying multiple bags around.

Method 3 | Send from a Convenience Store (7-Eleven / FamilyMart): The Fastest and Most Convenient

The biggest advantage of convenience stores is that you can send parcels anytime, even at night, and often 24 hours a day.

Please note

For 7-Eleven or FamilyMart:

Oversized cartons are not accepted. The total of the 3 dimensions usually must not exceed about 160-180 cm.
They do not provide cartons, so you need to bring your own.
They do not accept chilled or frozen shipments.

Steps

Pack the parcel yourself, as the convenience store will not provide cartons.
Check whether the store displays Takkyubin handling service at the entrance.
Take a Kuroneko form, usually placed near the coffee machine area.
Write the PotatoShip Japan warehouse address and your PotatoShip ID.
The staff measures the parcel, you pay, and it is sent out.

Best for: the moment when you realize at night or just before going back to the hotel that you bought too much.
