The myth of safety in Japan collapses and the deterioration of public peace is worried-this is a halfsided fact. Firstly by using the statistical data, it is revealed that the number of serious crimes in Japan has recently been increasing and the arrest rate has been decreasing in total. However the serious crime rate in Tokyo still stays one tenth as much as that in US large cities. Secondly the geographical distribution of crime is described. The distribution varies by the kind of crime in case of Tokyo. The existence of the police station is effective in limited area from the location in case of a local city. The trade-off relation with convenience of place can be found both in a Japanese local city and in US large cities. Thirdly the tactics to keep urban safety are discussed. Modern city planning paradigm “tower in the park” has a weak point in respect of public surveillance. The design for increasing the eyes on the street and promoting the community atmosphere of place should be still and again considered now. Moreover citizen's trials for safety guarding, recently being developed in most Japanese cities, are important key to the urban safety in future.
