The small-car maker has decided to spend 60 billion yen (USD 610 million) to build a new assembly plant in Indonesia, according to the Nikkei newspaper and other media.
It will come on top of a 40-billion-yen investment mainly to build a new engine plant just outside the Indonesian capital Jakarta, which Suzuki announced last year, the Nikkei said.
With the combined 100-billion-yen investment, Suzuki plans to create a comprehensive system to produce passenger vehicles, from lightweight, fuel-efficient engines to final assembly.
Japanese automakers have steadily expanded their presence in Southeast Asia, which has become a key consumer market due to its growing middle class and as a source of cheap workers.
Suzuki already has an extensive operation in Asia outside of Japan, producing more than half of its 2.88 million vehicles in the region in the fiscal year to March 2013, the Nikkei said.
Suzuki officials could not be reached immediately for comment.
