Toyota Motor Corp. will slash domestic production 54 percent in the current quarter as demand plunges in the U.S. and Japan.

The company's output, excluding its Daihatsu Motor Co. and Hino Motors Ltd. units, will drop to about 519,000 vehicles in the three months ending in March, compared with 1.13 million a year ago, according to figures derived from Toyota's latest full-year forecast.

Toyota spokesman Paul Nolasco declined to confirm the figures.
