Request on the Use of Power Banks

In recent years, there have been cases of smoke and ignition caused by power banks, both in Japan and overseas. To ensure the safety and security of all our guests, we kindly ask for your cooperation with the following matters regarding the use of power banks in the guestrooms.

1. Precautions when using and charging power banks

To prevent fires and other emergencies, please refrain from using or charging power banks in the following cases:

- Charging power banks when you are out of the room

- Using or charging power banks under the direct sunlight near the window

- Using or charging power banks on flammable materials, such as beds, sheets, etc.

When using power banks to charge portable electronic devices or charging power banks from the guestroom power supply, place them in a location where you can always monitor their condition, in order to allow you to detect and prevent any issues at an early stage.

2. Prohibition of the use of damaged or abnormal power banks

Do not use power banks that are damaged, swollen, or display abnormal heat generation. These are extremely dangerous.

3. Guestroom cleaning

If any of the above situations are observed during room cleaning, our staff may move your power bank or stop charging in order to ensure safety. Thank you for your understanding in advance.

We appreciate your understanding and cooperation.
