In recent years, bear sightings and human injuries have been reported across Japan, rapidly increasing the importance of bear damage countermeasures among local governments, lodging facilities, campsites, and forestry workers. Against this backdrop, Boujo Kenkyusho Co., Ltd. (Headquarters: Ogaki, Gifu) announced that its portable bear deterrent, 'IKAZUCHI,' underwent third-party sound pressure testing at the Tokyo Metropolitan Industrial Technology Research Institute. The testing included sound pressure level measurements and spectral analysis, confirming IKAZUCHI's high sound pressure performance and broadband frequency characteristics. Tests conducted at the institute confirmed a maximum of 127.0 dB at a distance of 0.10m and 107.9 dB at 1.0m. The analysis covered time-averaged values, maximum values, and spectral analysis, evaluating not just volume but sound dispersion and characteristics. 127 dB is comparable to the level near an aircraft engine, an extremely high sound pressure rarely encountered in daily life. Boujo Kenkyusho emphasizes a design that prevents wildlife from becoming accustomed to the sound, rather than just competing on volume. Since wild animals tend to lose vigilance when hearing the same sound repeatedly, IKAZUCHI is equipped with approximately 40 sound patterns that can be switched depending on the situation. Furthermore, it includes sounds and frequency bands not typically found in nature, providing stimuli different from standard alarm sounds. Designed as a portable, handy-type device rather than a stationary one, it can be used immediately during mountain climbing, night work, or at forestry and agricultural sites. As of May 2026, due to increased social interest in bear damage and media exposure, the company has received numerous inquiries and orders from municipalities, corporations, and facility managers. Currently, the company is receiving consultations from across the country regarding deployment in bear-prone areas and for facilities like campsites, leading to a decision to increase production. There is a growing trend toward 'preventative measures before damage occurs' rather than reacting after a bear is spotted. Boujo Kenkyusho intends to continue providing bear countermeasure solutions, including AI monitoring systems, deterrent devices, and repellent products.
FAQ
Is this relevant to Taiwan's bear population?
Yes, as Taiwan manages Formosan black bear conservation, non-lethal deterrent technologies are of high interest.
