TOKYO -- Japanese contractor Obayashi has started to build a dam almost entirely with robots, addressing the industry's labor shortage and aging workforce.

The site of the trial project is a concrete dam in Mie Prefecture, on the southeast coast of Japan's main island. The 84-meter-high structure is slated for completion in March 2023.
