Toyota will boost global production by about 300,000 units this year as it expects sales growth mainly in the US and emerging markets.

The Nikkei  said the automaker, at the end of 2011, had unveiled plans to build a record 8.65m Toyota and Lexus vehicles in 2012, up 24% from 2011. The revised plan calls for a roughly 30% increase from last year to nearly 9m units.

The change was prompted by stronger-than-expected sales in the key Japanese and US markets during the first half. Overseas sales are seen topping forecasts in the second half as well.

Domestic sales were pushed up by government subsidies for fuel-efficient vehicles. Increases in orders for such vehicles as the new Aqua hybrid resulted in a 83% year-on-year jump in domestic automobile sales to 920,000 units during the first half.

Overseas, hybrids were popular thanks to high crude oil prices, and the Camry sedan sold well. US sales jumped 29% to 1.05 million units.

The Nikkei said that, although the coming end of the subsidies is seen hurting domestic sales in the second half, Toyota plans to aggressively sell vehicles in emerging markets, including southeast Asia, where it has a roughly 60% share.

For 2013, Toyota intends to revise up its planned global production from 8.98m units to about 9.1m. Plans call for boosting output mainly in emerging markets, especially Brazil and Indonesia, where new factories will go online.
