This nonfiction work follows the 2005 JR Fukuchiyama Line derailment through the actions of bereaved family member Yasakazu Asano and the engineers who confronted JR West's organizational reform. Rather than reducing the disaster to individual error, it examines corporate culture, safety thinking, and the difficult dialogue between victims' families and the company.

A bereaved family member and the head of the responsible company look beyond blame to question the safety culture of a vast organization.
