A bear injured four people across two factories and one residential area in Fukushima City on Tuesday, with one injury classified as serious and three as mild. The animal was first spotted at a car parts factory, an emergency call reported employee bites, and authorities had not located the bear after the incidents. National data show 13 bear-related deaths in Japan last year and more than 50,000 sightings in the fiscal year ending March, more than double the prior record.
