Summary This study examines public awareness concerning experiences of crime victimization, anxiety about being a victim of crime, and local public safety and crime prevention measures. It was conducted with the objective of providing source material for understanding the awareness of public safety. In order to examine crime-related problems that resurface from time to time, this survey features police patrols and contact, electronic monitoring of people with a history of sexual crimes, and reporting child abuse.

Furthermore, this study has been conducted periodically to understand the interim changes in public awareness. The first survey was conducted in 2002, the second in 2004, the third in 2007, and this is the fourth survey.

Sampling Procedure Probability: Multistage
Mixed probability and non-probability
With the enactment of the Personal Information Protection Law, the access to the Basic Resident Register of local governments, if not for the purpose of surveys related to the federal government, has become restricted. For this reason, the respondents of this survey were selected using the following methods:

1) As a primary extraction, the total population of the districts chosen was summed up, and 150 streets in the survey area were extracted.
2) As a secondary extraction, 12 households were extracted randomly from the residential map (1,800 households in total) in advance at the headquarters of the survey company.
3) The sampling was performed as follows:
- Considering that the percentage of households living in housing complexes is increasing, a total of 1,240 households (68.9%) living in separate houses and 560 households (31.1%) living in housing complexes were extracted. The number of separate houses and housing complexes in each location was defined based on the properties of the survey area.
- Starting from the block address (banchi) with the second lowest number, every third house was extracted. The ones that could be clearly identified as shops and companies were excluded from the samples. In the case of housing complexes such as apartments, it is not possible to know the number of floors or rooms from the residential map. So, the number of samples to be extracted from each housing complex was defined based on the respective size, and every third household was extracted. Further, to make the floor of the households living in housing complexes as unbiased as possible, half the survey locations were extracted from the first floor and the other half from the top floor.
- The extracted households were checked on the residential map and assigned a number so that the surveyor could identify each unit.
4) Based on the residential map and an attribute specification table, the surveyor visited the selected households and requested them to participate in the survey if they met the criteria. However, if multiple members in a single household met the criteria, only one person in that household was requested to participate. Further, to reduce the bias in the response attributes, the extraction was performed according to the gender and age allocated in the specification table.
5) If the 12 criteria could not be completed in a single location due to the impossibility to survey the selected households (including when the gender or age classification did not match), more households were visited to extract a respondent whose gender, age, and residential classification met the missing criteria until the 1,800 answers were collected.
6) Further, given the difficulty in obtaining the collaboration from single-dweller households in past surveys, a single dweller was randomly searched from each of the 150 streets and surveyed, separately from the survey above.
7) Moreover, in 294 households, out of the 1,800 households extracted from the residential map, no one was home at the time of the visit. Three weeks after the completion of the main survey period, the survey staff deposited the questionnaire in the mailbox of these households unavailable during the first round and requested them to complete the questionnaire and return it by mail.
