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.
