With record reports of bear attacks on humans, Japan has been increasingly turning to high-tech solutions, as you might expect. However, reports suggest that Ohta Seiki, a firm making the animatronic robot Monster Wolf to repel bears from human-habituated areas, can’t keep up with demand. “We cannot make them fast enough,” company president Yuji Ohta told AFP.
This year’s order book for Monster Wolf has already hit 50 units. Hokkaido-based Ohta Seiki usually doesn’t even manufacture that many robot wolves in a whole year. According to the latest figures, bears killed 13 people in Japan last year. That’s more than double the fatality rate from the previous year. Sightings are up, too, with 50,000 reports of bears nationwide. That figure is more than double the previous sightings record.

Of course, fatalities are a statistic at the extreme end of the situation. There are also numerous non-fatal incidents where bears have seriously injured or scarred humans, entered homes, roamed around schools, scared guests at hot spring resorts, and even rampaged through supermarkets in Japan.

With the record upswing in bear attacks and sightings, it isn’t a big surprise that business is booming for Ohta Seiki. Its Monster Wolf product looks ferocious. The official product pages say that the robot wolf imitates its real wild world namesake, but it turns up the fear levels by “emitting intense LED lights and loud voices.” Ohta Seiki is currently asking customers to “wait two to three months” for their orders to be fulfilled.

The $4,000+ Monster Wolf has an infrared sensor to detect and target wild animals with its 50 types of loud noises, glowing red eyes, blue under-lighting, and neck swinging from side to side. The robot’s traversal of the terrain (wheels are an optional upgrade), animated movements, sounds, and lighting are powered by a combination of a 12V car battery and an (optional) solar charging panel.
Ohta Seiki has plans to expand its product range with a handheld version of Monster Wolf for hikers, anglers, and schoolchildren, reports AFP. It is also looking at leveraging AI cameras to improve its anti-bear tech.
Earlier in the year, we reported on bear-repelling drones being deployed around Ishinomaki City in Miyagi Prefecture to address concerns about a “bear infestation.”
