The 4-foot (1.3-meter) bear first attacked people at a bus parking lot and then entered a lodge where it was trapped in a souvenir shop and shot dead by a hunter, according to media reports.
No one suffered life-threatening injuries in the attack, which lasted about an hour, reports said.
A photograph from the scene showed the bear mauling a prone person in a parking lot while a man attempted to scare it off.
The rest stop is on a mountainous road that is open during summer months only to licensed buses and taxis. The area is frequented by tourists for its scenic views.
Akano said bear attacks are very rare in the area.
