A thrill-seeker live-streaming his ascent of Japan’s tallest peak, Mt. Fuji, slipped and fell down the mountain, sparking a manhunt, according to reports.

Police received calls from concerned viewers about the climber on Monday afternoon, outlet NHK reported.

The unidentified man broadcasted the climb to Japanese video site Niconico, which showed him panting and telling viewers the expedition had become “dangerous,” SoraNews24 reported.

“Can’t be helped, though,” the man said, according to the report.

Footage posted to Twitter shows the man lose his footing and fall down a slope near the mountain’s seventh station, the outlet reported.

The famous landmark has been closed since September, with local police warning about the dangers of climbing the mountain when it’s covered in snow, NHK reported.
