Violation case study - Seibukosan to North Korea
As administrative sanction by METI to this trader, export prohibition (both to a company and to a individual who run this company) for One year and one month (from July 27, 2011 through August 26, 2012) is imposed. According to Article 53 of FEFTL, the maximum penalty is for a period of not more than three years. (So, 13 months are not so bad?)
As for criminal penalty, METI already prosecuted Seibukosan in July 2009 in violation of FEFTL, the judgment in Fukuoka District Court was monetary penalty JPY 1,200,000 and the imprisonment for one year and half. (but with suspended sentence for 3 years)
I hear recently lots of FEFTL violations to North Korea. Not only WMD catch-all violation, but Japanese government have embargo stance to North Korea, even export of luxury item or commodity items are basically prohibited. Most of violations are by small companies who seek easy profit without compliance mind.
