A Japan Airlines plane was in flames as it landed on a runway at Tokyo's Haneda airport on Tuesday evening.
Footage on broadcaster NHK showed flames coming out of the windows of the aircraft and beneath it. The runway was also set alight.
The plane, which had taken off from Sapporo, collided with a coast guard plane, NHK said, citing authorities.
All 379 passengers and crew on board were evacuated, media reports quoted the airline as saying.
"We are currently assessing the extent of the damage," the airline said, according to an NHK report.
Japan's coast guard said one of the six people on board their plane escaped. The condition of the remaining five is not clear.
Japan Airlines Flight 516 departed from New Chitose airport at 16:00 local time (07:00 GMT) and was scheduled to land at Haneda at 17:40.
