The Chinese embassy in Japan has issued a notice to urge Chinese citizens in the country to stay vigilant amid a record surge in bear sightings and attacks across Japan.

A record 13 people have been killed and more than 100 injured in bear attacks across Japan since April, public broadcaster NHK reported Saturday.

The number of bear sightings nationwide from April to September reached 20,792, exceeding 20,000 for the first time in the first half of a fiscal year since records began in 2009, the Environment Ministry said earlier this week.

According to the Japanese government, compared to previous years, bear attacks since July this year have occurred more frequently within human habitats, with over 70 percent taking place in urban areas or near residential neighborhoods. Wild boars have also been spotted in urban regions, including Tokyo and Chiba Prefecture.

The embassy advised Chinese residents and travelers to check local government websites and social media for wildlife warnings, avoid high-risk areas, and refrain from hiking alone, especially at dawn or dusk.

It also recommended carrying bear deterrents such as sprays or bells. If signs of bear activity are detected, individuals should leave the area immediately. In case of a direct encounter, remain calm, face the bear, and back away slowly, as running or screaming could trigger an attack.

The embassy reminded that in case of emergency, people should contact local police and the Chinese embassy or consulates in Japan, or call the foreign ministry's global consular emergency hotline for assistance.
