Honda Motor Co. Ltd. is set to increase global vehicle production after enjoying higher than forecast sales in emerging markets over the past month.

Honda Australia Pty Ltd. reports an additional 90,000 vehicles will be built to fulfill sales across China, Thailand, India, Indonesia and Brazil. The parent company now expects demand in those countries to be 8% higher than earlier forecasts.

“Honda expects sales to continue to increase across these emerging markets, in light of further economic recovery predicted for the next financial quarter,” Honda Australia says in a statement.

The increase comes after Honda’s Japan production fell for the eighth month in a row in June, slipping 30.6% to 73,020 vehicles. Outside Japan, output declined for the ninth straight month, sliding 15.1% to 184,832.

First-half 2009 production totaled 376,363 units in Japan, down 37.1% from like-2008. Output fell 32.3% overseas, to 940,946, marking the first drop in 13 years.

Combined, the 6-month worldwide tally of 1,317,309 represented a 33.7% decline from year-ago and was the first decline in 11 years.
