It was completely unexpected that one TV program broadcasted three years ago would have such enormous influence throughout the nation. Most of blue security lights in use are 20W fluorescent lamps and brightness of streets illuminated by them is around 1lx which is far from 3lx, the recommendation for crime prevention. Interview surveys, illuminance measurement, and resident questionnaires are conducted in Nara prefecture, where first blue security lighting was installed, and other various regions. This report also includes results of surveys and studies conducted by other organizations and institutes. I hope this report gives some suggestions to regions where blue security lighting is already installed as well as regions considering to install it.
