Amid severe labor shortages, the use of unmanned aerial vehicles to perform human tasks is sure to grow, and DJI, the world's biggest drone-maker, is ready to respond, the firm's Japan head said.

Drones for industrial uses ranging from agriculture to infrastructure maintenance and security are becoming more popular, said Allen Wu, DJI's head of Japan operations. But he said he is doubtful about the potential for drone-based product delivery.

"For quite some time, we've figured that our main market in Japan is industrial, so our team has been focusing on it more," Wu said in an interview Wednesday.
