Thank you very much for your continued patronage of the Keio Plaza Hotel Sapporo.
In recent years, incidents involving overheating and ignition of mobile batteries (including other products with built-in lithium-ion batteries) have been reported both domestically and internationally.
To ensure the safety and security of all our guests, we kindly request your cooperation regarding the use of these devices in your guest room.

- Precautions for Use and Charging

During Sleep or Absence:
Please refrain from charging devices and ensure they are disconnected from power outlets when sleeping or when leaving your room.
Charging Locations:
Please avoid charging on flammable surfaces such as beds, sheets, and curtains, or near windows exposed to direct sunlight.
Management and Monitoring:
We ask that you manage your devices under your own responsibility while charging and monitor their condition regularly.
Abnormalities:
Please refrain from using any mobile batteries that show signs of damage, swelling, or abnormal heat generation.

- Regarding Housekeeping Procedures

Should our housekeeping staff observe any of the above situations during room cleaning, they may move the device or disconnect the charger to ensure the safety of the premises. We appreciate your understanding in this matter.

We thank you for your kind understanding and cooperation in maintaining a safe environment for all our guests.
