The CEO of Japanese automaker Subaru said Tuesday he and all other executives would return part of their pay until next March following an inspection scandal at the company.

"All executives will voluntarily return part of their pay," CEO Yasuyuki Yoshinaga told a press conference. 

Last month Subaru recalled 395,000 vehicles from its domestic market after announcing in October that it had allowed uncertified staff to conduct inspections of some vehicles.

Nine models, including a sports car that Subaru manufactures for Toyota, were recalled but vehicles sold overseas were not affected.

The recall is estimated to have cost 20 billion yen ($178 million), according to the automaker.
