The People's New Party was a Japanese political party formed on August 17, 2005, in the aftermath of the defeat of Prime Minister Junichiro Koizumi's Japan Post privatisation bills which led to a snap election. On March 21, 2013, party leader Shozaburo Jimi announced that he was disbanding the party.

General elections were held in Japan on 11 September 2005 for all 480 seats of the House of Representatives, the lower house of the Diet. Prime Minister Junichiro Koizumi called the election almost two years before the end of the term taken from the previous elections in 2003, after bills to privatize Japan Post were voted down in the upper house, despite strong opposition from within his own Liberal Democratic Party (LDP).
