There is no law that any car must be sold at a particular mileage in Japan.
There is an incentive for owners to get rid of their cars at a certain age due to rising rate of taxes the older the car gets. This is to "persuade" the public to get newer cars to meet increasingly stricter Japanese DOT standards, emissions, etc.
