Japanese authorities have warned residents Saturday to be aware of wild bears in the country's northeast after several people were attacked, including police officers.
The bears, measuring about 50 centimeters in height, were seen in the area, including Akita and Fukushima Prefectures.
Two police officers were attacked Saturday in the city of Kazuno in Akita while recovering the body of a missing man, according to Japanese media reports. The man had gone hunting for bamboo shoots in the mountains a few days earlier where he was found dead in the area with gash wounds. It remains unclear if he died due to a bear attack.
The officers are in serious condition, though not life-threatening, reports said.
In response, some wooded areas have been closed off in Kazuno "for an indefinite time,” The Associated Press quoted officials as saying in a statement.
News footage showed police officers putting up signs warning people to stay out of mountainous areas where the bears were sighted.
Over the weekend, patrol cars were dispatched together with a helicopter search to locate the bears.
Akita Prefectural Police have urged people to keep bells and other noise-producing devices on hand to scare the bears away in case of an encounter, and not to go out at night.
Thousands of Asiatic black bears live in the wild throughout Japan. Attacks have risen as the borders blur between the bears’ habitats and people’s dwellings. The scarcity of acorns, berries and other food, possibly connected to climate change, is also blamed for the surge in bear encounters.

South African scientists on Tuesday injected radioactive material into live rhino horns to make them easier to detect at border posts in a pioneering project aimed at curbing poaching.

The country is home to a large majority of the world's rhinos and as such is a hotspot for poaching driven by demand from Asia, where horns are used in traditional medicine for their supposed therapeutic effect.

At the Limpopo rhino orphanage in the Waterberg area, in the country's northeast, a few of the thick-skinned herbivores grazed in the low savannah.

James Larkin, director of the University of the Witwatersrand's radiation and health physics unit who spearheaded the initiative, told AFP he had put "two tiny little radioactive chips in the horn" as he administered the radioisotopes on one of the large animals' horns.

The radioactive material would "render the horn useless... essentially poisonous for human consumption" added Nithaya Chetty, professor and dean of science at the same university.

The dusty rhino, put to sleep and crouched on the ground, did not feel any pain, Larkin said.

The radioactive material's dose was so low it would not impact the animal's health or the environment in any way, he said.

In February the environment ministry said that, despite government efforts to tackle the illicit trade, 499 of the giant mammals were killed in 2023, mostly in state-run parks. This represents an 11 percent increase over the 2022 figures.

Twenty live rhinos in total would be part of the pilot Rhisotope project whereby they would be administered a dose "strong enough to set off detectors that are installed globally" at international border posts originally installed "to prevent nuclear terrorism", a pleased Larkin said, sporting a green hat and a khaki shirt.

Border agents often have handheld radiation detectors which can detect contraband in addition to thousands of radiation detectors installed at ports and airports, the scientists said.
