The principal data on special act offenses in 2011 is as follows.
Fig. 1-2-1-1 shows the number of persons newly received by public prosecutors for special act offenses since 1949. The number of persons received for all special act offenses sharply decreased when the traffic infraction notification system came into force in 1968, and then remained within the range of two to three million from 1975 through to 1984. It then sharply decreased again due to expansion of the scope of the system in 1987, but subsequently showed an overall decreasing trend. However, the number of persons received for special act offenses excluding violations of road traffic related acts started to increase from 2001, but then turned to follow a generally decreasing trend from 2008. It decreased by 7.7% from the previous year in 2011.
Fig. 1-2-1-2 shows the percent distribution of persons newly received by public prosecutors for special act offenses excluding violations of road traffic related acts by type of offense in 2011 (See Appendix 1-4 for the number of persons received for the respective offenses).
