In the present study, behavioral patterns of financial robberies who broke into banks and post offices in Japan were analyzed. The analysis was based on the newspaper database resources. The results of the analysis showed that the typical type of robbery, in which the criminal threatened a counter staff with a knife, accounted for only 60 percent of all financial robberies, and that atypical types of robberies had happened more frequently than expected. As the results of more detailed analysis in MDS (Multi Dimensional Scaling), it was found that the criminal could escape most easily when the criminal struck and robbed a bank customer who appeared to use a night-deposit safe. Finally, the method of the crime prevention in financial institutions was discussed based on the results above.
