TL;DR
Japan’s robotic wolf units, used to deter bears, are now in short supply due to high demand amid increasing bear encounters. The government and farmers rely on these devices as traditional methods struggle.
Japan is experiencing a shortage of its robot wolves, devices used to ward off bears in rural regions, as demand has surged amid rising bear encounters and attacks.
The robot wolves, developed by Ohta in 2016, are custom-made deterrents equipped with LED eyes, menacing fangs, audio clips, and sensors. They have become a critical tool in Japan’s efforts to manage its increasing bear population, which has led to more than 200 injuries and 13 fatalities since early 2025, according to government data.
Ohta, the manufacturer, reports that it cannot keep up with the current demand, which has caused shortages. The company’s president, Yuji Ohta, stated that they are producing units by hand and are asking customers to wait two to three months for new orders. The devices are used mainly by farmers, but orders are also coming from golf courses and rural workers, with upgraded versions planned to include mobility features like wheels.
Why It Matters
This shortage of robot wolves highlights the severity of Japan’s ongoing bear crisis, which has intensified due to habitat encroachment and food scarcity, compounded by an aging rural population vulnerable to attacks. The depletion of these deterrents could impact efforts to reduce incidents and protect residents and livestock.

Background
Japan’s bear problem has worsened over recent years, with official reports indicating a rise in sightings and attacks. In 2025 alone, over 50,000 bear sightings have been recorded nationwide, and the government has resorted to deploying the military to cull bear numbers, euthanizing nearly 14,600 animals—a record high. The robot wolves were introduced in 2016 as a non-lethal, innovative approach to managing bear populations, gaining popularity among rural communities.
“We make them by hand. We cannot make them fast enough now. We are asking our customers to wait two to three months.”
— Yuji Ohta, President of Ohta
“The increase in bear encounters is a serious concern, and we are actively seeking solutions to protect our citizens.”
— Japanese government spokesperson
