Japan set to elect female prime minister in landmark first
In the past twenty years, Japan has seen more than 10 prime ministers.
Actually, one expert compares assuming the country's top job to taking a "poisoned chalice".
But why does the country keep changing leaders? This is partly because of it being a "single-party system", says Professor James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the main political competition originates inside the party, rather than from external parties.
"So within the LDP there are vicious struggles within various groups - they all desire their own clique to secure the leadership position."
"So even though you could be selected as prime minister, the moment you're in office, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Party infighting fuel power struggles
- The leadership role is frequently called a "poisoned chalice"
- Political stability stays difficult to achieve despite financial power
