[2] Critical of Junichiro Koizumi's policies including privatization of the Japanese postal system, Suzuki, while on bail, announced the formation of The New Party Daichi.

In 2010, when the Supreme Court ultimately confirmed his bribery conviction, Suzuki had to give up his seat to serve his prison term.

In the 2007 regular election of the upper house, the party endorsed independent Ainu activist Kaori Tahara in Hokkaido (two-member district) who lost to the two major-party candidates.

It became eligible to receive public party funding and other benefits such as nominating dual candidates in lower house elections.

In Hokkaido, Daichi candidates – in turn, endorsed by TPJ – all lost their district races (including two incumbents), but the party won one proportional seat.
