A sudden fire near Haneda Airport sparked the evacuation of passengers as thick clouds of smoke billowed into the sky.

Authorities reported that the blaze started at a demolition site within the airport, where workers were dismantling an old hangar.

Footage captured from a distance shows a dense plume of smoke rising from the burning building earlier today.

More than 30 fire engines and emergency vehicles were deployed to the scene. Crews managed to bring the fire under control around two hours later.

Police and fire crews are investigating the cause of the fire and checking whether anyone was injured.

Airport officials said flight operations were not affected, with no delays or cancellations reported.

The hangar was located roughly 1.2 kilometres northwest of Haneda Airport's Terminal 3.
