International Patent Jurisdiction in Japan

According to an article by David Hill and Shinichi Murata, it is possible for a Japanese subsidiary of a foreign corporation to file a patent infringement suit against a Japanese company or subsidiary in a Japanese court based upon non-Japanese patent rights. Furthermore, any resulting judgment could be executed in the foreign country that issued the patent. Because most Japanese patent litigation can be completed in only one year, Japan could be the venue of choice for global IP enforcement programs.
