Installed on June 16 at the request of city officials, the latest Shika Sonic model specifically targets bear activity using frequencies proven effective during scientific evaluation. The device, mounted along a road one hundred meters south of the school building, contains four elevated speakers that emit sounds across a radius of approximately 100 to 150 meters, operating automatically overnight to avoid disturbing students.
Monitoring conducted by an AI-driven camera installed in front of the school has shown zero bear detections since the device was activated. According to Mayor Mikio Tanaka, "Before the installation, bears were sighted almost every day near the school. Since then, not a single one has been spotted. This is a major success, and I'm truly grateful for the improved safety of our children and the local community. Given these promising results, we're now considering expanding the use of the device to tourist areas as the next step."
During a field visit on September 1, Tsuji assessed operational parameters including sound levels, emission intervals, and battery performance, noting, "Since only one unit has been installed, it's still too early to determine the full effectiveness. We also need to study where the bears have gone. But the fact that no bears have been seen for two and a half months means we've cleared the first hurdle for now."
City records indicate 64 bear sightings were reported in Nanto City between January and August, all without incident.
