A climber remarkably fought off a huge black bear while clinging to a cliff with dramatic video footage showing the exact moment he was attacked by the animal.
The man escaped alive following the ordeal on Mount Futago, Japan, and filmed the heart-stopping encounter in a video that went viral online.
Screams can be heard in the video as the bear lunges towards the climber and the man starts to defend himself, kicking and punching the animal.
