Wow, was this woman really chased by a bear down a mountain?

Curtis and I (Hilary) are fighting over this footage of a woman snowboarding down a mountain in Japan.  Her name is Kelly Murphy and she claims she had no clue she was being chased as she came down the hill until she downloaded the video from her camera. Curtis is convinced it’s fake, I ‘m not so sure.   What do you think, real or fake?
