Request Regarding the Use of Mobile Batteries

Jan 18, 2026

Thank you very much for choosing to stay at EN RESORT Grandeco Hotel.

In recent years, there have been reports both in Japan and overseas of smoke or fire incidents caused by mobile batteries (rechargeable batteries).
In order to provide all guests with a safe and comfortable stay, we kindly ask that you observe the following precautions when using mobile batteries in guest rooms.

・Please use products that display the required certification mark of the country of purchase. In Japan, this is the PSE mark, and we recommend using products that have been certified as safe, including genuine products.

・Do not use mobile batteries that show any signs of damage, swelling, or other abnormalities.

・Please refrain from charging mobile batteries when leaving the guest room, such as when going out.

・Do not charge mobile batteries near windows where they may be exposed to direct sunlight, or on beds, sheets, or other flammable materials.

・When charging, please place the mobile battery in a location where you can continuously monitor its condition.

・During room cleaning, for safety reasons, our staff may move mobile batteries or stop charging if deemed necessary.

If you notice excessive heat, unusual odors, smoke, or any other abnormalities, please stop using the device immediately and contact the front desk.

We sincerely appreciate your understanding and cooperation.
