The Osaka police have begun investigating what might start the fire since there was a suspicion of arson based on the situation at the scene.

There is a report that a "man lit fire" in the building in Kita Ward in the western Japanese city, local media reported, citing investigative sources. The police were also informed that the fire had been started from liquid dispersed from a paper bag held by a man who appeared to be in his 60s.

"I saw smoke coming out and there were a lot of fire trucks and ambulances. People were being rescued by a ladder truck. At one point, there was a power outage in the surrounding area," a witness working at a nearby restaurant said.

The fire occurred in Osaka's Kitashinchi district where a number of bars and nightclubs are located.
