Request Regarding the Use of Mobile Battery Packs
Dear Guests
Thank you very much for your continued patronage of Chisun Hotel Hamamatsucho.
In recent years, incidents involving smoke or fire caused by mobile batteries have been reported both in Japan and overseas.
To ensure all guests can stay safely and with peace of mind, we kindly ask for your cooperation regarding the use of mobile batteries in guest rooms as follows:
- When leaving your room (e.g., going out), please refrain from charging mobile batteries.
- While charging, please use them in a place where you can personally monitor their condition.
- When charging portable electronic devices from a mobile battery, or when charging a mobile battery using the power supply in your room, please refrain from charging near windows exposed to direct sunlight or on/near flammable items such as beds, sheets, and curtains.
- Do not use any battery that is damaged, swollen, or generating abnormal heat under any circumstances.
- During room cleaning for guests staying on a Multiple Night Stay, if any of the above situations is observed, our staff may relocate the mobile battery for safety reasons. Thank you for your understanding.
We appreciate your understanding and cooperation.
