Hello, @寛紀中06755. Please check the box or the case. The SD card comes in a loose plastic envelope so it may have moved around inside the package while in transit. Others report that they found the card inserted in the bottom flap of the box.
If this is not the case, let our Support team at https://gopro.com/help/ContactUs know so they can help you with the next steps. They can be reached by chat or callback request.
@寛紀中06755, our team is currently working through a volume of contacts so our response time may be slightly longer than usual. If you already have submitted a contact request, rest assured, they'll contact you as soon as possible. We appreciate your patience and understanding.
