The Political Participation and Constitution in Japan by Shigenori Matsui: "On the other hand, Japanese citizens living abroad who had no address in Japan were deprived of any opportunity to participate in elections before 1998. Even after an amendment of Public Office Election Act in 1998, overseas voters were allowed to participate only in the proportional representation elections (page 11). The government finally amended the Public Office Election Act in 2006 to allow overseas voters to participate in election districts (page12)."
