Subaru recalled nearly 400,000 vehicles from its domestic market on Thursday due to an inspection scandal -- the latest to hit the beleaguered Japanese car industry.

The recall concerns nine models, including a sports car that Subaru manufactures for Toyota, but vehicles sold overseas were not affected, a spokesman told AFP.

Subaru admitted last month that uncertified staff had conducted vehicle inspections at two factories northwest of Tokyo.

It said at the time it would likely have to recall 250,000 cars at a cost of some 5.0 billion yen ($44 million).

It is not immediately known how much the wider recall of 395,000 vehicles will cost the group.

The affected cars were produced at the two factories between January 2014 and October 2017.

Cars bought before then will have been subject to compulsory inspections three years after purchase, a transport ministry official said.
