Exploratory Spatial Data Analysis (ESDA) is applied to the spatial pattern of residential burglaries in Tokyo, which was caused by new lock-breaking tools, called “lock-picking”. The official crime records of residential burglary and breaking and entering in the 23 wards in Tokyo from 1996 to 2000 (n = 41151) are aggregated by census tract and then matched with the national census data in 1997. The burglary rates are calculated by house type: detached, high-rise and low-rise housings. The burglary rate increased only at high-rise housings after the new lock-breaking tools appeared. Global and local Moran's I statistics revealed that the clusters of detached house burglary were most significant and static, while those of high-rise housing displaced dynamically. Other findings are reported and discussed.
