Toyota will resume production of some hybrid models in Japan from Monday but rival Honda will extend a suspension of auto assembly amid continued disruption caused by the March 11 earthquake.
Toyota on Thursday said it would resume production of its Prius and some Lexus hybrid models because it now expects to be able to procure parts by then and wants to prioritise output of models with higher demand.
But Honda said it would suspend auto production until April 3 at two domestic plants amid parts shortages due to disruption caused by the impact of the 9.0 magnitude earthquake and tsunami, and also a limited power supply.
The company, however, will resume production of motorcycle and power products at its Kumamoto plant from Monday.
Toyota on Wednesday said it was likely to slow production at some US plants due to a shortage of parts from quake-hit Japan.
The world's largest automaker had earlier delayed plans to restart car production, with supply chains crippled by the biggest earthquake ever recorded in Japan and the raging 10 metre tsunami it generated.
Economists are reviewing daily their increasingly bleak forecasts for an economy that has seen infrastructure along the northeast coast shattered, while power outages hit the Tokyo region. Firms have closed plants, hitting output.
