Bear Attacks in Japan - Why they're rising and how to stay safe

Japan’s mountains are becoming increasingly dangerous. Encounters between humans and bears—both

Asiatic black bears on Honshu and brown bears in Hokkaido—are now at record levels. In 2023–2024, Japan

saw the highest number of bear attacks ever recorded, prompting warnings from wildlife experts and local

authorities.


The Alarming Rise in Bear Attacks

According to Japan’s Environment Ministry, the country recorded 219 bear attacks and six deaths in the year

up to March 2024—the worst year since records began in 2006. Between April and November 2023 alone, 193

attacks injured over 210 people. Bear sightings have also skyrocketed, with rural areas reporting more than

1,400 bear encounters last year—roughly triple the average a decade ago.

Experts estimate Japan’s bear population has surged to around 44,000 Asiatic black bears on Honshu and

nearly 12,000 brown bears in Hokkaido. The population rebound is partly due to stricter hunting laws and rural

depopulation, which have allowed forests to expand unchecked.


Why the Attacks Are Increasing

Several overlapping factors explain the sharp rise in conflicts.

Food shortages: Poor acorn and nut harvests drive hungry bears into towns searching for food.

Changing hibernation patterns: Warmer winters and climate shifts delay hibernation, increasing encounters.

Abandoned farmland: As Japan’s rural population ages and shrinks, overgrown fields create “edge zones”

where bears and humans meet.

Fewer hunters: With hunting licenses declining and firearm rules tightening, bear numbers have grown

unchecked.

Loss of fear: Bears used to being near humans or fed at tourist spots become bolder and more dangerous.

The government is responding by loosening shooting restrictions in bear-prone regions and stepping up local

patrols, but prevention remains the most effective protection.


How to Avoid a Bear Encounter

If you hike, camp, or live near Japan’s forests, take these steps seriously. This is exactly what I would do to

stay safe.

Make noise while walking. Use a bear bell or talk aloud to avoid surprising one.

Hike in groups—bears rarely approach multiple people.

Stay alert at dawn and dusk, when bears are most active.

Never leave food or garbage outdoors. Bears have excellent smell and learn quickly.

Avoid hiking during poor visibility or after dark.

If you see a bear: stay calm and back away slowly. Don’t run or make sudden moves. Make yourself look

larger, wave your arms, and speak firmly. If attacked defensively (for example, a mother with cubs), lie

face-down and protect your neck. If attacked predatively (rare), fight back with all force.

Local governments often issue bear-warning alerts, so check signage, websites, or community boards before

heading out.


The Bottom Line

Japan’s rising bear attacks are a result of deep environmental and social changes. While the trend is worrying,

understanding bear behavior and taking sensible precautions can help keep you safe. Respect their habitat,

stay alert, and remember: coexistence begins with awareness.

Answers:
1. Because there are more bears now, and they are coming closer to towns. Bears cannot find enough food in
the mountains, and there are fewer hunters, so the number of bears is growing.
2. Stay calm and do not run. Back away slowly, speak loudly, and make yourself look big. If it is a mother bear
protecting her cubs, lie face-down and protect your neck.
3. Warm weather makes bears wake up earlier and hibernate later, so they are active longer and meet people
more often.
4. People should not leave food or garbage outside, make noise when walking, and report bear sightings to
local authorities
