Toyota said Monday operations had resumed at some of its domestic plants after an accident at a parts supplier's factory a week earlier hit output.
The world's largest automaker by volume restarted five production lines at four factories in northeastern and central Japan, with parts supply still affected following the accident that led to the halt of 13 lines at eight of the automaker's 14 assembly plants.
Toyota said it would decide later Monday on when to restart the remaining eight lines at six factories.
An explosion occurred on Oct. 16 at the factory belonging to Chuo Spring in the city of Toyota, Aichi Prefecture, which makes suspension springs.
Chuo Spring said Friday it restored the affected production equipment.
The parts shortage disrupted production of Toyota's flagship cars including its RAV4 sport utility vehicles.
Toyota has faced a series of production problems in recent years, including a glitch in its parts ordering system in August.
