Japan to vote for new PM amid political uncertainty: All you need to know

The Japanese legislature, known as the Diet, is set to meet for an extraordinary session to vote for the next prime minister.
The vote on Tuesday follows the collapse of a 26-year-old partnership earlier this month between the Liberal Democratic Party (LDP) and the smaller Komeito party after Sanae Takaichi took the helm of the LDP.
The LDP has been the dominant force in Japanese politics since the 1950s, but over the past two years, it has lost its majority in both legislative houses after failing to address a series of problems, including a major corruption scandal and Japan’s cost-of-living crisis.
Now, the LDP is at risk of losing power completely unless it can bring another opposition party to its side.
Some Japanese media reports suggested on Sunday that the LDP had reached an agreement with the Japan Innovation Party (Nippon Ishin) to form a coalition that would ensure that Takaichi is elected prime minister. But details of the partnership remain unclear, and the two sides have yet to confirm it.
Who is Sanae Takaichi, and why is she controversial?
Takaichi, 64, is the former protege of late Prime Minister Shinzo Abe and a member of the LDP’s conservative faction.
She was chosen to replace Prime Minister Shigeru Ishiba as head of the LDP after he stepped down in September. Takaichi ran on a platform of aggressive fiscal expansion to resolve Japan’s ongoing economic problems.
Takaichi is also known as a foreign policy hawk who wants to strengthen Japan’s military, and she holds conservative views on same-sex marriage.
Following her election as LDP leader on October 4, the LDP and Komeito held policy negotiations. They hit an impasse when Takaichi failed to address Komeito’s concerns about corporate donations, according to Jeffrey Hall, a lecturer at Japan’s Kanda University of International Studies.
The disagreement follows a recent LDP scandal that revealed that party members had diverted more than 600 million yen (approximately $4m) of donations to a slush fund.
“[Takaichi] didn’t give them what they considered a serious answer on their concerns about corruption scandals, and they wanted more serious regulations around funding, especially corporate donations,” he told Al Jazeera.
Can Takaichi still become the next prime minister?
Takaichi still has the chance to become Japan’s first female prime minister, but experts say it will take some horse-trading.
The LDP has 196 seats in the lower house of the Diet, and Takaichi needs at least 233 seats to secure a majority. She could do this by negotiating with one of Japan’s other opposition parties, like the Japan Innovation Party.
