A koban is a Japanese satellite police station like this one in the city of Osaka. Some are quite elaborate, while others are unpeopled places pretending the cops are working (the crooks are supposed to take the hint and go someplace else). We find this one quite irritating. The police person seems to be talking down to an elderly gentleman in nightclothes. They need to do much better. In fact, if we were in Osaka we might start a riot.
