Please return your WiFiBOX at the nearest rental station as soon as possible.

If you are using a 5G device, please see the information
below.
Return it at the nearest rental station
The quickest and easiest option is to take the device to the nearest WiFiBOX rental station and return it there.
Please refer to
this page for a list of rental station locations.

Rental charges will apply for each additional day until the device is returned. Please return it as soon as possible.
If you cannot return it at a rental station
If there is no WiFiBOX rental station nearby, you may return the device by courier.
However, courier returns may cost more because you are responsible for the shipping fee, and rental charges will continue until the device arrives at our facility.
Please refer to this page for details about courier returns.
If you took the WiFiBOX outside Japan
There is no supported way to return a WiFiBOX from outside Japan.
Please submit a lost device report using
this form.
If you did not purchase Wi-Fi Insurance, you will be required to pay the applicable compensation fee.

Although shipping the device from overseas may be physically possible in some cases, the international shipping cost and late fees charged until it arrives in Japan will usually exceed the compensation fee.
WiFiBOX also contains a lithium-ion battery, so finding a courier that can accept the shipment may be difficult.
For these reasons, submitting a lost device report will generally be the most practical and cost-effective option.
If you are using a 5G device
5G devices can only be returned at designated locations.
They cannot be returned at unsupported rental stations.
Please check
this page in advance for a list of locations where 5G devices can be returned.
