A withering factory town in the rust belt is looking for revival through a dose of Prime Minister Shinzo Abe's "robot revolution."

Kadoma's population in Osaka Prefecture has shrunk 13 percent as the nation ages, prompting mergers among elementary schools and emergency services departments. Factories can't find enough people to run assembly lines, further threatening an industrial base that includes titan Panasonic Corp. and smaller businesses like Izumo Co., a maker of industrial rubber.

Yet Izumo President Tsutomu Otsubo doesn't believe the solution involves finding more people. He'd rather find more machines to do the work so his company can capitalize on Abe's plan to quadruple Japan's robotics sector into a ¥2.4 trillion ($20 billion) industry by 2020.
