In the context of increasing number of bear attacks on humans in Japana local company that makes devices shaped like ‘robot wolf’ to scare away wild animals faces to a demand that had never had. In the first months of the year, it received orders for more than 50 Monster Wolf to scare away bears; Before, I wouldn’t have received nearly as many in a whole year. These robot wolves, who have moving limbs, lights LED and make soundsare increasingly being used to protect farms and other rural areas inhabited by humans.
During 2025, bears killed 13 people in Japanto which must be added countless non-fatal incidents with injuries, scares and material damage. They were produced in total around 50,000 sightings, more than double that of 2024indicating that, in certain areas of the country, bears are coming into contact with humans on a much more regular basis. Local authorities seek to avoid these incidents and many owners resort to devices to scare away dangerous fauna, such as the robot wolf produced by Ohta Seiki. But the small business can barely keep up with orders and customers have to wait three to four months to receive them, according to Tom’s Hardware.
The Monster Wolf robot wolf has been manufactured since 2016, costs more than $4,000 and uses an infrared sensor to detect wild animals before activating its deterrent mechanisms. The set is powered by a 12V car battery and can be supplemented with an optional solar panel for recharging. It measures 80 cm high and 1.2 meters long.
Ohta Seiki’s robot wolves can perform vocalizations of about 50 different animalsbut its main function is to howl like a wolf. With a power of 90 decibelsthe sound can be heard more than a kilometer away, enough to scare local wildlife and deter animals further away.
The system also has glowing eyes and bottom LED lightingdesigned to enhance your silhouette and size, as well as moving parts to make it look more realistic. Units can be placed in fixed locations, but there is a option with wheels which allows some mobility to protect larger areas.
Ohta Seiki is also working to improve its robot wolf model with AI image recognitionso that it can respond intelligently depending on the type of animal it encounters, adjusting its sounds and behavior to more effectively scare it away from the area.
According to the media, it is also developing a portable version that could help protect people like hikers and fishermen.
