Toyota Motor has suspended operations at a dozen factories in Japan due to a system failure, NHK reported Tuesday.
It is not immediately clear when the system will be restored, the report said.
All local plants except for the Miyata plant in Fukuoka Prefecture and Toyota unit Daihatsu’s plant in Kyoto are affected, according to NHK.
Operations at the world’s largest automaker by sales ground to a halt last year when one of its suppliers was hit by a cyberattack.
