Osaka Mayor Toru Hashimoto, who heads the opposition Nippon Ishin No Kai (Japan Restoration Party) told the party convention on Saturday that they must work hard to ensure that the ruling Liberal Democratic Party and its coalition New Komeito Party do not secure a majority in this summer's upper house election.
It was the party's first major gathering since last December's lower house election in which it finished third.
Hashimoto, who co-founded the party with former Tokyo Gov Shintaro Ishihara, said the political landscape will never change if the old guard remain in power, Fuji TV reported.
At the convention, party members unanimously endorsed the pledge to revise the country's constitution to scrap the war-renouncing Article 9. Hashimoto has also advocated abolishing the upper house.
In January, Hashimoto met with Prime Minister Shinzo Abe to discuss areas where the two sides could work together, but nothing came of it. During the election campaign, both Hashimoto and Abe said it would be difficult to work together as they differed on key policy issues.
On Saturday, Hashimoto said the Japan Restoration Party was willing to explore alliances with smaller opposition parties, such as Your Party, to prevent the LDP and New Komeito from taking control of the upper house.© Japan Today
