The combined domestic output of the eight major automakers rose 9.9 percent in October from a year earlier for the second straight month of increase, data released by the firms show.

The figures were helped by robust demand in North America and a recovery from the slump sparked by the termination last year of a subsidy program for the purchase of green cars.

The eight companies produced 825,137 vehicles in October, all posting an increase from the year before except Nissan Motor Co., which has been shifting production abroad.
