Potatoship Japan Warehouse AddressImportant: You must add your Potatoship Member ID after your name or address so we can identify your parcel correctly.

Method 1 | Send from your hotel → the easiest option

Most hotels in Japan, especially chain hotels or hotels rated three stars and above, can help guests send domestic parcels via Yamato Transport / Kuroneko TA-Q-BIN.

How it works:

1. Put your overweight items into a box or bag and seal it properly

2. Ask the hotel reception: “Could you help me send a domestic parcel by Yamato?”

3. Request a Kuroneko TA-Q-BIN shipping form

4. Fill in the delivery address as: Potatoship Japan Warehouse + your Potatoship Member ID

5. Hand it to the hotel staff, who will measure the parcel and tell you the cost

6. Pay the fee and continue enjoying your trip

Best for: travellers whose luggage is already full and who want to sort everything out back at the hotel in one go.

Method 2 | Send from a department store or shop → the most direct option

Many large department stores in Japan can help arrange delivery to a Japanese address immediately after purchase.

In some cases:

• purchases over ¥1,000 may qualify

• once the items are basically packed, the store may help send them by Kuroneko TA-Q-BIN to any address in Japan, including the Potatoship warehouse

How it works:

1. Finish shopping

2. Ask the staff whether they provide TA-Q-BIN delivery service

3. Take a Kuroneko shipping form and fill in: Potatoship Japan Warehouse + your Potatoship Member ID

4. Pay the fee

5. The shop will arrange immediate dispatch

Best for: people who want to shop and ship at the same time without carrying too many bags around.

Method 3 | Send from a convenience store (7-Eleven / FamilyMart) → the fastest and most convenient option

The biggest advantage of convenience stores is flexibility — you can send parcels at night, late in the day, or even 24 hours a day in some locations.

Please note:

At 7-Eleven or FamilyMart:

• oversized parcels are not accepted

  • usually the total of the three sides must not exceed around 160–180 cm

• cardboard boxes are not provided, so you must prepare your own

• chilled or frozen parcels are not accepted

How it works:

1. Pack the parcel yourself first, as convenience stores do not provide boxes

2. Check whether the store is a TA-Q-BIN handling location

3. Take a Kuroneko TA-Q-BIN form, usually found near the coffee machine or service area

4. Fill in Potatoship Japan Warehouse address + your Potatoship Member ID

5. The staff will measure the parcel, collect payment, and send it out

Best for: travellers who suddenly realise they bought too much before heading back to the hotel.

🧰 Where to buy cardboard boxes in Japan (latest 2026 guide)

If you bought too much and need to prepare your own box, you can usually buy one at:

• Japan Post Office → around ¥100–¥220 per box

• Yamato / Kuroneko service counters

• Daiso / Seria (100-yen shops)

• Bic Camera, Donki, and large shopping centres

Recommendation: boxes in sizes 100 to 150 are usually the most practical for clothes, snacks, and miscellaneous items.
