Fig. 4-1-2-5 shows the number of cases and persons referred to public prosecutors for special act offenses (excluding violations of traffic related acts; hereinafter the same in this subsection) committed by visiting and other foreign nationals (from 1980). The number of cases and persons referred to public prosecutors for special act offenses committed by visiting foreign nationals both reached a record high level in 2004, but then started to decrease, and were 5,784 cases (down 20.5% from the previous year) and 5,148 persons (down 15.1% (id.)) in 2010, respectively. From 1990 both the number of cases and number of persons referred to public prosecutors for special act offenses were larger with visiting foreign nationals than other foreign nationals.
Examining referred cases for special act offences committed by visiting foreign nationals revealed that by type of offense the proportion of Immigration Control Act violations was overwhelmingly high. Fig. 4-1-2-6 shows the number of cases referred to public prosecutors for offenses high in proportion over the last 10 years. The number of referred cases for Immigration Control Act violations was on an increasing trend from 2001, but then continued to decrease every year from 2005, and was 3,672 in 2010 (down 22.5% from the previous year). With the category of the violation of referred cases for Immigration Control Act violations in 2010, illegally overstaying was the largest in number at 2,085 cases, followed by illegally residing at 680, failure to carry a passport/refusal to present a passport at 550, and engaging in activities other than permitted under their status of residence at 222 (Source: The Criminal Investigation Bureau, National Police Agency).
