Ongoing privatization of Japan Post relates to that of the national postal service and one of the largest banks in the world. After years of debate, the privatization of Japan Post spearheaded by Junichiro Koizumi finally started in 2007. The privatization process is expected to last until 2017. Japan Post was one of the nation's largest employers, as one-third of Japanese state employees worked for it. It was also said to be the largest holder of personal savings in the world. Criticisms against Japan Post were that it served as a channel of corruption and was inefficient. In September 2003, Koizumi's cabinet proposed splitting Japan Post into four separate companies: a bank, an insurance company, a postal service company, and a fourth company to handle the post offices and retail storefronts of the other three. After the Upper House rejected privatization, Koizumi scheduled nationwide elections for September 11, 2005. He declared the election to be a referendum on postal privatization. Koizumi subsequently won the election, gaining the necessary supermajority and a mandate for reform, and in October 2005, the bill was passed to privatize Japan Post in 2007.
