Tokyo Suburb to Buy Anti-Bear Spray Amid Rising Bear Sightings
Hachioji, a Tokyo suburb, is spending ¥15 million ($93,000) on anti-bear sprays and electric fences as Japan faces a record increase in bear encounters. According to the environment ministry, bear sightings nationwide topped 50,000 last fiscal year, more than double the previous record, leading to increased urban encroachment and fatalities.
Why are bears entering urban areas like Hachioji?
Bears are moving into built-up areas as they emerge from hibernation and find easier access to residential zones. Hachioji sits on the outskirts of the capital region, where popular hiking trails lead directly into forested mountains.
Broadcaster NHK reported 11 sightings or signs of bears in Hachioji since April. A motion-activated camera captured a black bear near a residence on April 29.
To stop this trend, national and regional governments are clearing bushes along riverbanks and the boundaries between neighborhoods and mountains. This effort aims to remove the natural cover bears use to enter cities undetected.
How is the local government responding to the rise in attacks?
Local governments are shifting toward emergency spending and tactical manuals. Hachioji announced a plan to purchase 700 anti-bear sprays for schools and community organizations, according to local government spokesman Ryosuke Sato.
The city’s ¥15 million budget covers sprays, movable electric fences, and high-pitched sound devices. Sato stated the city is also drafting a manual to coordinate with police and hunters when bears appear on city streets.
This urgency follows a deadly trend. The environment ministry reported a record 13 people killed by bears last fiscal year. Between April 1 and May 30 of this year, another five people died and 20 were injured.
What happens when bears evade capture in cities?
Urban bear encounters are becoming harder to resolve quickly, leading to significant civic disruption. In Utsunomiya, north of Tokyo, all schools closed earlier this month after a bear roamed the city.

The animal evaded dozens of police officers and hunters for four days before capture. This mirrors the Fukushima incident, where a bear remained at large for several days after attacking factory workers.
These events suggest a shift in bear behavior. Animals are no longer just passing through; they are adapting to urban environments and evading traditional trapping methods.
Comparison of Recent Urban Bear Incidents
| Location | Behavior/Impact | Outcome |
|---|---|---|
| Utsunomiya | Roamed city; caused school closures | Captured after 4 days |
| Fukushima | Opened window/tap; attacked 4 people | At large for several days |
| Hachioji | 11 sightings; captured on camera near homes | Emergency spending on sprays/fences |
