Floods submerged vehicles at 80 Japanese underpasses in a decade

Floods submerged vehicles at 80 Japanese underpasses in a decade

Floodwaters trapped 134 vehicles at 80 underpasses in 33 prefectural capitals across Japan over the past decade.

The figures come from a survey of all 104 public bodies managing 866 underpasses in those capitals.

Underpasses can flood during heavy rain, leaving vehicles unable to move.

In August, torrential rain flooded several underpasses in Chiba Prefecture, near Tokyo, and two people died at separate locations in the prefectural capital.

Warning systems linked to water gauges or other alerts were in place at 415 underpasses, about 48 percent of those surveyed.

Barriers that can be operated remotely or activate automatically were installed at 54, just over 6 percent.

Japan’s transport ministry has begun restricting traffic in advance at some underpasses during heavy rain and has asked local governments to take similar steps.
