Toyota had been aiming for a high February production plan to meet strong demand.

Toyota said it would slash its global production plan for April by 150,000 units to 750,000 vehicles, compared with the original schedule reported to suppliers earlier this year.
Toyota's overseas output climbed 5.6 percent to 3.35 million vehicles through June, while production in Japan fell 18 percent to 1.73 million.
Production lines will be switched back on at its 14 factories across the country, Toyota said.
The automaker will suspend production on three lines at its Motomachi plant in September. That follows suspensions at its Tsutsumi plant.

Toyota could lose up to 480,000 units from January through March.
