Japan's koban system (including one-officer "chuzaijo" posts) draws overseas attention as a community-based approach to public safety. When the official name was changed from "hashutsusho" to "koban" in the 1994 revision of the Police Act, one reason cited was that "KOBAN" was already known abroad. The photo shows the Paseo de Marianas koban in Saipan (via Wikipedia). Koban are said to have been "exported" to Hawaii and New York as well.
Growth is especially notable in Asia. South Korea and Taiwan have long had similar posts; Indonesia introduced koban from 2004. In Singapore, which adopted the system earlier, the nickname "KOBAN" has stuck alongside the formal "Neighborhood Police Post. Like Japan, officers patrol around the clock, and residents can even change the address on their ID cards there. It is encouraging to see the system evolve to suit each country.
Mainichi Travel on B1 of Palaceside Building in Takebashi offers various overseas tours. Keeping an eye out for "KOBAN" abroad could be fun — though we hope you never need their help for the wrong reasons.
