According to police reports, the fire started when a female passenger’s mobile battery, kept inside her bag, suddenly ignited while the train was running.

The owner of the battery and a woman sitting next to her suffered burns and were immediately taken to the hospital. Fortunately, their injuries are considered minor.

As a result of the incident, Osaka Metro temporarily suspended operations in both directions of the Midosuji Line. This disruption affected more than 50,000 passengers before service was eventually restored.
