A piece of concrete fell from a junior high school building in Inazawa, Aichi Prefecture, and injured a student on the morning of November 6, the city's board of education said.
The concrete dropped from an eave at Inazawa Nishi Junior High School at around 8:20 a.m. and struck the head of a student who was cleaning at the time, according to the board. The student was hurt.
The board did not say how seriously the student was injured, or what condition the building was in before the concrete fell. It also did not say whether the school had been inspected for deterioration.
Falling concrete from aging school buildings has become a recurring safety concern in Japan, where many public schools were built during the postwar construction boom and now require repairs that local budgets often struggle to cover.
