Police Emergency Number - INI
110 is Japan's emergency police reporting number. Operations began in 1948 in 8 major cities including Tokyo and Osaka, and it was unified nationwide in 1954. The design utilizes the characteristics of rotary dial telephones, combining '1' with a short rotation distance and '0' with a long rotation distance to enable quick operation during emergencies while preventing misdialing. Currently, it receives approximately 8 million reports annually, with technological innovations such as GPS location transmission and video reporting systems also advancing.
