On the 8th, a 69-year-old suspect was arrested on the Kyushu Shinkansen train running in Kumamoto prefecture for igniting the floor. Police are investigating the motives and details of the suspect's motives, assuming that he lit the fire immediately after boarding from Kumamoto Station.
Kiyoshi Miyake, unemployed in Hakata-ku, Fukuoka City, was accused of arsoning the floor with liquid on the downhill Kyushu Shinkansen train running between JR Kumamoto Station and Shin-Yatsushiro Station before 9 am on the 8th. (69) was arrested on suspicion of attempted arson.
The fire went out without spreading, and about 140 people in the Shinkansen train were not injured.
According to police investigations so far, Miyake had a ticket from Kumamoto Station, but according to JR Kyushu, the Shinkansen emergency buzzer is about 5 minutes after leaving Kumamoto Station. It means that it was operating around 8:42 am.
According to the police, the police admitted the suspicion to the investigation and stated that "I tried to imitate the case where a passenger lit a fire in the Keio Line in Tokyo last month." I'm investigating the motives and detailed circumstances, assuming that the fire was lit immediately after boarding from Kumamoto Station.
