AUTHENTIC JAPAN Inc. (Head Office: Fukuoka City, Fukuoka Prefecture; President and CEO: Kazusou Kuga), which operates the location tracking service "Kokohéli" for mountains and oceans, will begin offering free rentals of life jackets equipped with the GPS tracker "Kokohéli Marine" at beaches in Fujisawa City, Kanagawa Prefecture (Katase Higashihama Beach, Katase Nishihama/Kugenuma Beach, and Tsujido Beach). This initiative, offering free rentals of GPS tracker-equipped life jackets to the general public at beaches, is the first of its kind in Japan (according to our research). In 2025, the number of beachgoers at the three beaches in Fujisawa City, Kanagawa Prefecture, was 1,783,782, an increase of 18.9% from the previous year, reaching a level exceeding that before the COVID-19 pandemic. Among these, Katase Higashihama Beach and Katase Nishihama/Kugenuma Beach attract many visitors not only from Kanagawa Prefecture but also from the Tokyo metropolitan area. This initiative aims to ensure user safety and conduct a demonstration for establishing a rapid detection and rescue system through location tracking at sea. Furthermore, an introduction and demonstration of this initiative will be held at the "Enoshima Miami Beach Show 2026" beach opening event on July 1st (Wed). Background The beaches in Fujisawa City are major summer tourist destinations representing Shonan, attracting a large number of beachgoers every year. In 2025, Katase Higashihama Beach had 653,250 visitors, Katase Nishihama/Kugenuma Beach had 1,128,000 visitors, and Tsujido Beach had 2,532 visitors. While many people enjoy the sea, there are situations at beaches where tracking location is crucial, such as lost children, people being swept away while swimming, rip currents, and sudden health issues. Especially at sea, unlike on land, there are few landmarks, and it can take time to find someone. The life jackets to be rented will be equipped with "Kokohéli Marine," which has a GPS function.
