All but one of Japan's top-five automakers boosted production worldwide in May over a year earlier, according to data released by the five companies Thursday.

Toyota Motor Corp. said output at its plants worldwide rose 12.8% to 415,574 units -- 257,872 produced domestically, up 12.4% for the 10th consecutive month of rise, and 157,302 units overseas, up 13.3% for the first rise in two months.

A Toyota official said there were signs of a recovery in demand in the domestic market, while the North American and Asian markets continued to be firm.
