Japan on course to choose woman prime minister in landmark first
Over the last two decades, the country has seen more than 10 prime ministers.
Actually, one expert likens taking up the country's top job to taking a "poisoned chalice".
However, what is the reason does the country frequently replace prime ministers? This is partly because of it being a "single-party system", explains Prof James Brown of Temple University Japan.
The LDP's grip on the political landscape means the primary rivalry originates inside the party, instead of from opposition groups.
"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 might be chosen as prime minister, as soon as you're in power, you have many individuals scheming to try to get you out again."
Key Factors Behind Rapid Turnover
- One-party dominance restricts external competition
- Internal factional rivalries fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Political stability stays difficult to achieve despite financial power
