Press Release】Wintering of Japanese deer in Kamikochi at an altitude of over 1,600 meters was confirmed for the first time using GPS tracking technology.
On May 25, 2026, our company issued a press release titled “[First Confirmation] GPS Tracking Technology Confirms Deer Wintering at Altitudes Over 1,600 m in Kamikochi” via PR TIMES.Through a joint study utilizing our GPS collar “LoggLaw G2C” and the wildlife data management cloud “Animal Portal,” we have demonstrated for the first time in Japan that Japanese deer remain and overwinter in forested areas at elevations exceeding 1,500–1,600 meters in Kamikochi, Northern Alps.

Survey Overview
This study was conducted by our company in collaboration with the Kamikochi Branch of the Nature Park Foundation (contact: Mr. Sohei Katori) and Professor Shigeyuki Izumiyama of Shinshu University.Continuous tracking of the Japanese deer’s location via Animal Portal, using a LoggLaw G2C unit, revealed that contrary to the previously held assumption that “deer move to high-altitude areas only in summer and descend to lower elevations in winter,” the animal remained in the Kamikochi forest zone at elevations exceeding 1,600 m throughout the winter.
Furthermore, since the tracked individual was a pregnant female, this suggests the possibility of successful reproduction in the Kamikochi area, highlighting the growing need for impact assessments on alpine ecosystems and scientific wildlife management.
Products and Services Used
- LoggLaw G2C (Collared GPS for Wildlife Damage Control) — A next-generation GPS collar equipped with LTE-M communication and a solar panel. It supports long-term monitoring in mountainous and cold regions.
- Animal Portal (Wildlife Data Management Cloud) — A cloud platform that visualizes GPS positioning data in real time on a map, enabling sharing and analysis across multiple organizations.
Significance and Future Developments
This is the first time in Japan that the overwintering of Japanese deer has been confirmed in the forested areas of Kamikochi at an altitude exceeding 1,600 meters. This data is crucial for the conservation of Kamikochi’s ecosystem, including its alpine plant communities. Moving forward, we will continue to collaborate with research institutions, local governments, and national park managers to support science-based wildlife management using GPS collars and cloud infrastructure.
