A year after a knife attack on a bullet train left one passenger dead and two wounded, authorities and railways are trying to take steps — especially visible ones — to prevent similar crimes.

Experts are calling to start baggage inspections at train stations, though railways remain reluctant to do so because of the congestion and inconvenience they would cause.

The attack occurred on the Tokaido Shinkansen Line on June 9, 2018, when Ichiro Kojima allegedly attacked two women with a knife on the Nozomi 265 bound for Shin-Osaka Station from Tokyo and fatally stabbed Kotaro Umeda, 38, who tried to stop him.
