Videos show schoolgirls fighting off animals, while others show people feeding bears, with some so realistic that users struggled to distinguish between fact and fiction

If a record number of fatal bear attacks wasn’t terrifying enough, experts say a torrent of AI-generated videos in Japan purporting to show people in close encounters with the animals is only adding to public anxiety – and could put people at greater risk.

While headlines about real attacks and disruption appear on a regular basis, monitors of online content are warning social media users not to be taken in by realistic videos on platforms such as TikTok of the animals attacking or interacting with humans.

Governor of one prefecture says he is considering asking the military for help to tackle increasing attacks amid thousands-strong bear population

Knowing what to do in the event of a close encounter with a bear was once a concern only for hikers and foragers in Japan. Now, however, people in populated areas are being urged to learn how to protect themselves following a spate of attacks, as the animals leave their natural habitats in search of food.

Bear encounters are generating almost daily headlines. In the past week in Akita prefecture, the animals attacked a jogger and a walker in built-up areas, while another terrorised four people before holing up inside a nearby house. None of the victims was seriously injured.
