File this under things you definitely didn’t know:
Japan has a serious bear problem. Asian black and brown bear populations are exploding, and the solution to the problem is robots:
First produced in 2016 by the manufacturer Ohta, Monster Wolf was designed to deter agricultural pests such as boar, deer, and Asian black and brown bears.
The creative solution quickly went viral for its red LED eyes, menacing fangs, and furry pipe frame, and it was rapidly deployed to keep bears from entering heavily populated areas.
Starting at around $4,000, each Monster Wolf is equipped with battery power, solar panels, and detection sensors. Its speakers are programmed with over 50 audio clips, including human voices and sirens audible for more than half a mile.
The problem?
These robots aren’t built on an assembly line. Each Monster Wolf is custom-made, and Ohta can’t keep up with the current demand.
The country’s rapidly aging population is also making it particularly susceptible to bear attacks, especially in more rural regions. Since the beginning of 2025, the government has reported at least 200 injuries and 13 fatalities as a result of bear attacks—over twice the previous mortality record.
Official data also recorded more than 50,000 bear sightings across the country during the same period.
Last year, Japan deployed its own military to help cull bear numbers. More than 14,600 animals were captured and killed — an all-time high and almost triple the previous year’s tally.
All of this is to say :
- A gap exists in the market for anyone who can produce a terrifying robotic wolf quickly enough to meet Japan’s needs.
- If you’re dealing with bears in your neighborhood — as many of the towns surrounding my town are — forget the bear-proof trash cans, motion-activated sprinkers, and electric fences. All those may be effective, but none are as cool as a robot wolf patrolling your neighborhood.
