When Asian black bears attack humans, they rear up on their hind legs and knock victims over with their paws. Then they bite them on an arm or leg and snap on the victim's head, this being the most dangerous part of the attack. Asian black bear attacks have been increasing in Kashmir since the Kashmir conflict. In November 2009, in the Kulgam district of Indian-administered Kashmir, an Asian black bear attacked four insurgents after discovering them in its den, and killed two of them. In India, attacks on humans have been increasing yearly, and have occurred largely in the northwestern and western Himalayan region. In the Chamba District of Himachal Pradesh, the number of Asian black bear attacks on humans has gradually increased from 10 in 1988–89 to 21 in 1991–92. There are no records of predation on humans by Asian black bears in Russia, and no conflicts have been documented in Taiwan. Recent Asian black bear attacks on humans have been reported from Junbesi in Langtang National Park, Nepal, and occurred in villages as well as in the surrounding forest. Li Guoxing, the second person in history to have received a facial transplant, was a victim of an Asian black bear attack. Nine people were killed by Asian black bears in Japan between 1979 and 1989. In September 2009, an Asian black bear attacked a group of tourists, mauling nine people and seriously injuring four more at a bus station in the built-up area of Takayama, Gifu. The majority of attacks tend to occur when Asian black bears are encountered suddenly, and in close quarters. Because of this, Asian black bears are generally considered more dangerous than brown bears, which live in more open spaces and are thus less likely to be surprised by approaching humans. They are also likely to attack when protecting food.  2016 saw several attacks by Asian black bears in Japan. In May and June four people were killed by Asian black bears in Akita prefecture while picking bamboo shoots, and in August a female safari park worker in Gunma prefecture was killed when an Asian black bear climbed into her car and attacked her. In September, a 63-year old fisherman, who was also a black belt in karate, managed to fight off an Asian black bear attack by destroying its right eye. In the past, the farmers of the Himalayan lowlands feared Asian black bears more than any other pest, and would erect platforms in the fields, where watchmen would be posted at night and would beat drums to frighten off any interlopers.
