To Our Valued Guests,

Thank you for your continued patronage of Shin-Yokohama Grace Hotel.

Recently, there have been reports nationwide of fires and smoke emissions caused by the improper use, aging, or malfunction of devices containing lithium-ion batteries, such as portable power banks. To ensure a safe environment for our guests and to prevent fire-related incidents, we kindly ask for your cooperation regarding the following points:

**Refrain from leaving devices unattended or sleeping while charging**
Please do not leave the room or go to sleep while charging portable power banks or smartphones. We ask that you charge devices only when you are present and able to immediately notice any irregularities (such as abnormal heat, strange odors, or smoke).

**Do not charge on bedding or clothing**
Charging on flammable materials—such as beds, futons, or clothing—can obstruct heat dissipation and lead to fires; therefore, please strictly avoid doing so.

**Do not use damaged or deformed devices**
Please refrain from using or charging devices within the hotel if they have sustained strong impacts (e.g., from being dropped) or show signs of swelling or deformation, as these pose a high risk of fire.

**Action to take if irregularities occur**
Should you notice any strange odors or smoke coming from your device during your stay, please contact the front desk immediately.

We appreciate your understanding and cooperation in helping us ensure the safety of your stay.
