Criminological research has long revealed that crimes are concentrated in specific “hotspots” This phenomenon is known as the “law of crime concentration” (LCC). Most studies have tested LCC in North American and European cities, ignoring Asian cities. This study aims to reveal crime concentration in Tokyo and Osaka, Japan. Eight types of property crimes that occurred between 2008 and 2017 in Tokyo and Osaka and had been aggregated by the census enumeration district were analyzed. The calculated Gini coefficients for each crime type indicated three facts. First, degree of concentration depended upon crime type. Commercial burglary was the most concentrated crime type, and theft from vehicle and theft of vehicle were the most dispersed. Second, the degree of residential burglary in Tokyo and Osaka could be comparable to Antwerp. Third, crime concentration patterns either remained stable or became more concentrated over time. This study concludes that LCC is partially validated in two Japanese cities.
