TOKYO - A fledgling conservative party led by popular Tokyo Governor Yuriko Koike is gaining traction in its challenge to Japanese Prime Minister Shinzo Abe's ruling bloc ahead of a general election next month, media polls released on Thursday showed.
Abe, a conservative who returned to power in 2012, is calling the snap lower house poll hoping his Liberal Democratic Party-led (LDP) coalition can maintain a simple majority. It currently holds a two-thirds "super" majority.
The chamber will be dissolved later on Thursday and the election is expected to be held on Oct. 22 The LDP-led bloc began with a strong lead but Koike's new party - only formally launched on Wednesday - has upended the outlook after she announced she would lead the group herself.
Koike, a media-savvy former LDP lawmaker and defence minister often floated as a candidate to become Japan's first female prime minister, said on Wednesday she would not run for a lower house seat herself, but speculation that she will persists.
A survey by the Mainichi newspaper showed 18 per cent of voters plan to vote for Koike's Party of Hope compared to 29 per cent for Abe's ruling Liberal Democratic Party (LDP).
An Asahi newspaper poll showed 13 per cent planned to vote for Koike's party versus 32 per cent for the LDP. Both surveys asked voters their preference for proportional representation districts where ballots are cast for parties rather than specific candidates.
Abe's decision to call an snap election has been bolstered by an improvement in his personal ratings, which have risen to around 50 per cent from around 30 per cent in July.
The emergence of Koike's party - which she describes as pro-reform and conservative - has thrown the main opposition Democratic Party into turmoil. The Democrats are struggling with defections and single-digit ratings and now appear in danger of being absorbed by the Party of Hope.
Democratic Party leader Seiji Maehara will propose that the party run no candidates in the election and let its members run under the Party of Hope flag, domestic media reports said.
The proposal could end up splitting the party, an often fractious mix of conservatives and liberals whose rocky 2009-2012 reign tainted its image with many voters.
Koike, 65, defied the LDP to run successfully for Tokyo governor last year and her novice local party then crushed the LDP in a metropolitan assembly election in July.
Her Party of Hope shares policy space with the business-friendly LDP, but Koike has staked out different stances on two issues likely to appeal to voters.
She wants to freeze a planned rise in the national sales tax to 10 per cent from 8
