A ski resort in 性视界 said Friday it had received reports of bear sightings, while a snowboarder described how one of the animals chased him on the piste.
A record 13 people have been killed by bears across the country since April, with incidents reported regularly of bears entering homes, roaming near schools and rampaging in supermarkets.
"We've been patrolling to check if there are bear footprints every day since we received two sighting reports on Sunday," said Kazuya Shirakawa of Hakuba47 Mountain Sports Park in Nagano Prefecture.
