Your Party chief Yoshimi Watanabe on Monday reiterated that his group won't form a coalition with the Democratic Party of Japan or the Liberal Democratic Party, but he did indicate his door is open to anyone to join him if they agree with his party's political agenda.

"Both the LDP and the DPJ are calling for bigger government, want to introduce tax hikes and are controlled by bureaucrats," Watanabe, whose party scored big gains in this month's Upper House election, said at the Foreign Correspondents' Club of Japan.

"But there are those who oppose such stances within the two parties. I call on those hidden comrades within the LDP and the DPJ to join us in a political realignment," Watanabe said.
