Karuizawa Town in Kitasaku District has temporarily shifted its policy from releasing captured bears after 'learning' to euthanizing them for a limited period. The change responds to repeated human injuries and appearances of bears in residential areas across the prefecture and concerns that bears' wide-ranging movements could cause harm to neighboring municipalities.
