Abstract
Recently, crime in apartment buildings has increased rapidly in Japan, and Ministry of Land, Infrastructure and Transport devised a design guideline for crime prevention of multi-family housing in 2001. But, we guessed that old condominiums has many troubles on improvement against crime measures, because this design guideline is more applicable not to old condominiums but to new ones. The purpose of this study is to clarify the situation of crime, crime prevention measures, improvement for enhanced security, and resident-based anti-crime activities, and to pick out the problem for improvement. In order to the purposes, we carried out questionnaire to 2136 management associations of condominiums in autumn 2004, and 877 associations answered it. The results were as follows: new condominiums under ten age, had many experiences of improvement for enhanced security. Because they had existing facilities, such as intercom system and CCTV, so it did not take expense of partial improvement. On the other hand, vast expense was necessary for large-scaled improvement of old condominiums. Main difficulties in improvement were high-cost and agreement formation of residents, so some social supports, such as administrative support and advices of experts are future problems.
