A review of crime prevention activities in a Japanese local government area since 2008: Beautiful Windows Movement in Adachi Ward

There have been limited reports on crime prevention policies by local governments in Japan, which is one of the safest countries in the world. This article reviews crime prevention policies in Adachi Ward, which used to have the highest crime rates in Tokyo. The government of Adachi Ward introduced the “Beautiful Windows Movement” (BWM) in 2008. Based on BWM, Adachi Ward implemented various programs and interventions based on two different aspects: the aspect of preventing minor crimes and disorder in partnership with the police referring to the Broken Windows Theory and the aspect of literally making the Ward beautiful in cooperation with citizen volunteers. After 11 years of implementing BWM, the number of recorded crimes in Adachi Ward declined the most in Tokyo and residents’ sense of security improved significantly. This case study highlights the advantage of the duality of BWM to both reduce crimes and improve residents’ sense of security.
