A bear entered a home in Gunma Prefecture early Friday morning and seriously injured an elderly couple.
A woman in her 70s from the city of Annaka called emergency services around 20 minutes after midnight, reporting that a bear had entered the home and bit her husband, police said.
The couple were sleeping on the first floor of a two-story house when the man, also in his 70s, heard a noise outside and opened a window to investigate. The bear, about one meter in length, proceeded to attack the couple before leaving the scene immediately afterward.
The husband suffered head lacerations, while the woman sustained a broken arm. Both are not in a life-threatening condition and are expected to recover in about three months.
Their son, who was on the second floor at the time, did not suffer injuries.
