There have been cases of speed-tickets turned into deportation notices for international students. Would Japan do that too for a speed limit violation?
Great question: Going over 30KM/h over the speed limit in a non-highway zone (red ticket) in Japan is a criminal offense: it goes to court, there is a criminal record filed, they can suspend or revoke your driver’s license, and it can absolutely cause a VISA to be revoked or not renewed.
And unlike in the US they actually do enforce the laws there.
