Japan's eight leading automakers produced a total of 858,248 vehicles at domestic plants in October, up 19.7 percent for the first increase in two months, as they stepped up production after disruptions caused by the March 11 earthquake and tsunami, according to their data as of Monday.

Toyota Motor Corp. and Nissan Motor Co. boosted domestic output by more than 30 percent from a year earlier — 33.5 percent to 316,597 units at Toyota and 32.9 percent to 115,932 at Nissan.

Honda Motor Co. rolled out 95,051 units, up 18.3 percent for its first rise in 11 months.

Three other carmakers — Suzuki Motor Corp., Daihatsu Motor Co. and Fuji Heavy Industries Ltd. — also reported output gains.

But Mitsubishi Motors Corp. curbed production of export models to address the yen's appreciation, resulting in a 17.9 percent output fall to 50,757 units.

Mazda Motor Corp. manufactured 0.8 percent fewer vehicles at 75,633.
