Essential Steps for Successful Hotel Delivery

To ensure your package arrives safely and to avoid any trouble, please follow these steps before placing your order:

1. 【CRITICAL】Create a Separate Amazon Japan Account Amazon accounts from other countries (e.g., USA, UK, Germany) cannot be used on the Japanese site.

  • The Ironclad Rule: You must create a new, dedicated account at Amazon.co.jp.
  • Pro Tip: To prevent login errors on the mobile app, we strongly recommend using a “different email address” from your home country account.

2. Verify with Your Accommodation First Before confirming your order, contact your hotel or host (via email or message) to ask if they can accept Amazon packages for guests. Note: Some Airbnbs or unmanned hotels may refuse deliveries.

3. Match Your Booking Name The recipient name on the package must exactly match the name used for your hotel reservation (in Roman alphabet).

4. Accurate Address Input In the address field, clearly include the “Hotel Name” and your “Check-in Date” in addition to the hotel’s physical address.

5. Perfect Delivery Timing To ensure you are on-site to receive it, schedule the delivery for the day after your check-in date.
