Three years after the deadly collapse of a road tunnel, families of the people who died have urged greater attention to aging infrastructure nationwide.

A false ceiling in a highway tunnel in Yamanashi Prefecture collapsed in December 2012, crushing vehicles. Pins holding concrete panels in place were found to have rusted through.

Kunio Matsumoto, 64, father of a 28-year-old woman who died, was among the people who laid flowers and offered prayers for the nine victims at the Chuo Expressway's Sasago Tunnel.
