Japan set to choose woman prime minister in landmark first
Over the last two decades, Japan has had more than 10 leaders.
Actually, a specialist compares taking up the country's highest office to taking a "poisoned chalice".
But why does Japan frequently replace prime ministers? This is partly because of it being a "one-party democracy", explains Prof James Brown of Temple University Japan.
The LDP's grip on the country's politics means the main political competition originates inside the party, instead of from external parties.
"Therefore inside 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 leader, the moment you're in office, you have many individuals scheming to try to get you out again."
Key Factors Behind Frequent Changes
- One-party dominance limits outside challenges
- Party infighting drive power struggles
- The prime minister's position is frequently called a "poisoned chalice"
- Government continuity remains elusive despite economic strength
