A Russian hiker was hurt in a bear attack in Okutama, a mountainous town in western Tokyo, becoming the latest victim of intensifying man-animal conflict in Japan.

Authorities said the man, reported to be in his 30s but not named, sustained serious injuries to his arm and face. He remained conscious and was airlifted to a local hospital.

According to local media, emergency services received a call reporting the incident at around noon on Sunday.

The man had been hiking alone when he came across the bear. He was not carrying a bear bell or other deterrent.

In the wake of the attack, police and local hunters searched the area but could not find the bear, Kyodo News reported.

Authorities later installed a cage in the town in a bid to capture the animal.

The area has reported roughly 40 bear sightings since April, officials noted.

Japan confirmed its first fatal bear attack of 2026 earlier this month. The East Asian nation saw an unprecedented 13 casualties last year.

Authorities said a 55-year-old woman found dead in the northern Iwate prefecture last month was killed by a bear. Two other bodies discovered in Iwate on 7 May and Yamagata prefecture on 5 May, respectively, were suspected to be linked to bear attacks as well.

One of them was identified by NHK as 69-year-old Chiyoko Kumagai, who had disappeared after going into a mountain forest to collect edible wild plants.

Japan saw a surge in dangerous bear encounters in 2025, with the animals entering homes, schools, supermarkets, and hot spring resorts.

Authorities are concerned that this year could turn out to be even worse in terms of animal attacks.

Wildlife experts say the rise in attacks is linked to increasing bear populations, climate-related food changes, depopulation of rural areas, and abandonment of farmland. All of these factors are driving bears closer to human settlements.

Japan’s brown bear population has doubled over the past three decades to around 12,000, while Asian black bears on the main island of Honshu now number about 42,000, according to a 2025 government report.

Last year, the Japanese government deployed the military to Akita after bear sightings in the region jumped sixfold to over 8,000 and deadly attacks surged.
