Japanese Authorities Inspect Toyota HQ Over Certification Irregularities

TOYOTA - TOKYO - Japanese transport ministry officials launched an on-site investigation at Toyota Motor's (7203.T) headquarters on Tuesday after irregularities were found in its applications to certify certain vehicle models.

The widening fallout over certification tests stems from a safety test scandal at Toyota's Daihatsu compact car unit and has also ensnared other Japanese automakers after the ministry ordered industry-wide checks of certification practices.
