Car production in Japan plunged in April due to a continuing shortfall in the supply of parts.
Toyota said its domestic production fell 74.5% compared with the same month last year.
Honda's output plummeted 81%, while Nissan reported a 48.7% decline at its factories.
Carmakers have been facing a shortage of parts since the earthquake and tsunami on 11 March disrupted their supply chains.
As a result, they have been forced to suspend or slow down production at their factories.
The BBC reports the effects of the disruption have been felt offshore.
Toyota factories outside Japan produced 25% fewer vehicles in April.
Honda has reported a decline of 43.5% in output at its overseas factories, while Nissan said its foreign output dipped by 12.7%.
