“However, assaults by brown bears are way more extreme. Brown bears are considerably bigger and stronger, and their assaults way more typically result in critical accidents or fatalities,” he added.

But why is there a rise in bear assaults this 12 months and the way is Japan responding?

Here’s what we all know:

Where are the assaults taking place?

According to Japan’s public broadcaster, NHK, the nation’s northern prefectures – districts below the management of a prefect or governor – have been the worst affected by bear assaults.

Earlier this week, NHK mentioned 5 folks had been killed in Iwate, two in Hokkaido, one every in Nagano and Miyagi, and 4 in Akita to date this 12 months.

Bear sightings in Akita prefecture have risen sixfold this 12 months, and bears have attacked greater than 50 folks since May. Most of the assaults in Akita have been by Asiatic black bears and have taken place in residential areas.

According to NHK, on November 9, a bear assaulted a 78-year-old girl in Gojome Town after which attacked a 50-year-old girl who got here to assist when she heard the older girl screaming. Both had been admitted to a hospital in Akita City and are nonetheless alive. An aged girl in Akita metropolis was killed after encountering a bear whereas engaged on a farm in late October.

In an Instagram publish final month, the Kenta Suzuki, the governor of the mountainous area, mentioned that “the scenario has already surpassed what the prefecture and municipalities can deal with on their very own”.

“Exhaustion on the bottom is reaching its restrict,” he added.

In an interview final month, Billy Halloran, who’s from Auckland, New Zealand, and at the moment lives in Japan, advised CNN a couple of critical black bear assault he had skilled within the woods of Myoko in northern Japan when he went for a run in early October.

He mentioned he noticed two bears observing him from bushes close by and, when he tried to again away, one bear began transferring in the direction of him. “It was round my dimension, it was an grownup, it was at the very least 60 or 70 kilos (about 132 to 154 kilos),” he advised CNN.

He held up his arm in entrance of his face, however the bear seized it and pushed him to the bottom. “Then in a single chunk, my arm was achieved,” he mentioned.

The bear assault has left him with a damaged arm and an injured leg, Halloran mentioned. He has required three surgical procedures, and steel plates have been inserted into his arm.

Attacks have additionally taken place in central Japan. Last month, a bear entered a grocery store in Numata metropolis and attacked buyers, in line with NHK. While no one was killed, police officers mentioned some folks sustained accidents, though they didn’t say how critical they had been.

The surge in assaults has prompted some nations, together with the United States and the United Kingdom, to subject journey advisories to residents dwelling or travelling to Japan.

In a “wildlife alert” issued on Wednesday, the US Department of State mentioned: “Bear sightings and assaults have elevated in elements of Japan, particularly in municipalities near or adjoining to populated zones.

“In Sapporo, authorities closed Maruyama Park in Sapporo, which is adjoining to the US Consulate General, for 2 weeks following a bear sighting within the park.

“Although the Consulate is positioned outdoors of the park, we encourage all guests for routine or different providers to be diligent and conscious of your environment.”

In late October, the UK’s Foreign Office warned British travellers to not enterprise alone into forest areas and to keep away from leaving litter and meals waste in the event that they do.

Why are bear assaults on the rise?

Mochizuki mentioned one purpose is a meals scarcity for bears within the mountainous areas of the nation. He mentioned bears primarily feed on acorns and beech nuts, which haven’t been considerable this 12 months.

“In years when pure meals is scarce, bears usually tend to enterprise into human settlements in quest of meals,” he advised Al Jazeera.

According to the Ministry of Environment, there was a surge of assaults in 2023 following poor acorn yields. Some consultants say local weather change is a purpose for the low manufacturing.

Mochizuki famous that bear populations have additionally expanded within the nation “because of long-term conservation and decreased searching strain” and mentioned that this issue has elevated bears’ “contact zones with people”. According to the federal government, the general bear inhabitants is at the moment greater than 54,000.

In 2012, the Environment Ministry’s biodiversity centre mentioned the variety of black bears was about 15,000, whereas brown bear numbers have doubled since 1990, though it didn’t give numbers.

Mochizuki mentioned that one more reason bear assaults are rising is rural depopulation, brought on by younger folks leaving their villages and transferring to cities for higher job alternatives.

“As rural areas age and decline, unmanaged fields and village edges create easy accessibility routes for bears,” he added.

How are the Japanese authorities managing the scenario?

Last week, Japan’s navy and riot police had been deployed to the scenic mountainous area of Akita to attempt to include the surge in bear assaults.

But whereas riot police are authorised to shoot the bears, navy personnel should not and should work alongside non-public hunters.

“The Japan Self-Defense Forces are legally restricted to nationwide defence and catastrophe aid, and subsequently don’t have any authorized authority to kill wildlife,” Mochizuki mentioned.

“Hunters, in contrast, maintain official searching licences and firearm permits below Japan’s Wildlife Protection and Management Law. They might be formally authorised by prefectural governments to conduct nuisance management, together with the taking pictures of bears when mandatory,” he added.

So the navy has been serving to the area’s area people by organising bear traps or eradicating carcasses of the bears shot by hunters they’re working with.

What are native folks doing?

Residents of affected areas, particularly Akita, have been utilizing AI-surveillance techniques and drones to alert them to the presence of bears, in line with Akita’s mayor.

NHK reported that individuals have additionally been suggested to not depart meals round after they go on picnics within the forest, and likewise to chop down any nut-bearing bushes that will appeal to bears.

What different measures might be taken to cease bear assaults?

Mochizuki mentioned three most important measures can show efficient.

“Firstly, meals sources round human settlements needs to be eradicated,” he mentioned. “Proper administration of rubbish, deserted fruit bushes, and backyard produce is the simplest safety measure.”

He added that bodily obstacles similar to electrical fencing round farms or village perimeters “can considerably scale back bear entry”.

“Thirdly, early detection via digicam traps, sensors and GPS information, fast communication via cellular alerts may also help communities reply shortly to bear presence,” he mentioned.

Mochizuki acknowledged that whereas the navy and police have been deployed to help bear hunters, the nation faces a scarcity of hunters and wildlife personnel because of its ageing inhabitants.

“Recruiting youthful members and rising municipal workers capability is important,” he mentioned.

Last, Mochizuki highlighted the significance of teaching residents and vacationers in regards to the bears.

“Many folks, together with worldwide guests, are unfamiliar with bear behaviour and security practices and wish higher steerage,” he mentioned.
