Who could replace Ishiba as Japan's prime minister

A party veteran who has held a variety of roles, including economic security and internal affairs minister, she lost to Ishiba in the LDP leadership race in a run-off vote last year. As premier from 2011 to 2012, he worked with the LDP to push through legislation to double Japan's consumption tax to 10% to help curb bulging public debt - earning a reputation as a fiscal hawk. A former finance ministry bureaucrat, Tamaki co-founded the Democratic Party for the People in 2018 and advocates increasing people's take-home pay by expanding tax exemptions and slashing the consumption tax.
