  • IMPERIAL HOTEL, TOKYO

In recent years, there have been increasing reports of portable battery chargers (power banks) overheating, emitting smoke, or catching fire, both in Japan and abroad.
To ensure a safe and secure stay for all our guests, we kindly ask for your cooperation with the following precautions when using portable battery chargers in your room.

  • Please refrain from charging portable batteries when you are not in the room.
  • When charging a mobile device using a portable battery, or when charging the battery itself using the in-room power outlets, please avoid placing it in the following areas:
    Near windows exposed to direct sunlight
    On flammable materials such as beds, sheets, or curtains
  • While charging, please ensure the device remains in a visible location where you can monitor its condition at all times to prevent any potential issues.

Should any of the above situations be observed during housekeeping, our staff may move the battery to a safer location as a safety precaution. We appreciate your understanding.
Thank you for your cooperation and understanding.
