Toyota Motor Corp. plans to invest some 20 billion yen to double engine production capacity to some 400,000 units per year at its engine plant in Kanda, Fukuoka Prefecture, sources said Wednesday.
The nation's top automaker will announce the plan Thursday, they said.
The Kanda factory went on stream last December as Toyota's first domestic engine plant outside Aichi Prefecture, where the automaker is based.
Toyota decided to expand the Kanda plant because it is having a tough time securing workers in the Aichi area, the sources said.
Engines produced at the Kanda plant are used mainly for sport utility vehicles assembled in Miyawaka, Fukuoka Prefecture.
