Protecting the World with a Single Rope: Yamaguchi Takaharu, Civil Engineer

Civil engineer Yamaguchi Takaharu inspects dams and bridges while dangling from a single rope. From the Akashi-Kaikyo Bridge to major highways, requests for his expertise come from across the country, and even abroad! We follow his inspection of a huge bridge in Hyogo Prefecture that requires extraordinary skills and roughly a hundred different pieces of equipment. In the winter of 2021, Yamaguchi made his first attempt to take measurements of a massive dam with a robot. But the project sees a series of failures. What does he think of the trend toward automation in his field? This civil engineer entrusts his life to a single rope in the pursuit of public safety.
