Japan set to choose female prime minister in historic first
Over the last two decades, the country has seen more than 10 leaders.
In fact, a specialist likens taking up the nation's highest office to taking a "cursed cup".
However, what is the reason does the country frequently replace prime ministers? This is partly because of it being a "one-party democracy", says Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry comes from within the party, rather than from external parties.
"Therefore inside the LDP there are vicious struggles within various groups - they all want their own clique to secure the leadership position."
"So even though you might be selected as leader, as soon as you're in office, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- Single-party rule limits outside challenges
- Internal factional rivalries fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Political stability stays elusive despite economic strength
