Why police in Japan are now allowed to shoot bears
Troops deployed in northern Japan to help stop bear attacks after surge in casualties
Japan has recorded at least 13 bear attack fatalities since April, marking the highest toll on record.
Authorities have launched a campaign to cull bears, with amended rules permitting police to use rifles against the animals.
Riot police personnel trained with firearms and the Self-Defence Forces have been deployed to northern prefectures like Akita and Iwate, which have seen the most attacks.
Experts attribute the surge to a tripling of the Asiatic black bear population since 2012, due to hunting restrictions and warmer winters.
Dwindling natural food supplies are driving bears into villages and urban areas, prompting urgent appeals for assistance from local authorities.
