More than 50,000 bear sightings were recorded nationwide, more than double the previous record set two years before, according to official data. The animals were seen entering homes, roaming near schools and rampaging through supermarkets and hot spring resorts on an almost daily basis.
The number of bears captured and then culled nearly tripled from a year earlier to 14,601, also marking an all-time high.
Some northern regions also reported in April more than four times as many sightings as last year as the animals emerge from hibernation, local media said.
