Although the leader of Kokumin Shinto (People's New Party) has ruled out the possibility of forming an alliance with another party, that doesn't mean he isn't interested in cooperating on policy where possible.

"If another party agrees to adopt our proposal, like our political campaign to reconsider the postal privatization bill, (Kokumin Shinto) would partially (cooperate) with that party," Tamisuke Watanuki said. "But that does not mean that (our party) would do everything together."

Watanuki is one of the "postal reform rebels" who in August 2005 voted against then Prime Minister Junichiro Koizumi's postal privatization bill and left the Liberal Democratic Party after being told the party would not back them in the Lower House election the following month.
