Japan set to choose woman prime minister in landmark first
In the past twenty years, the country has seen more than 10 leaders.
Actually, one expert compares taking up the nation's top job to taking a "poisoned chalice".
But why does the country frequently replace leaders? 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 country's politics means the main political competition originates within the party, instead of from external parties.
"So within the LDP there are vicious struggles within different factions - they all want their own clique to secure the leadership position."
"Thus although you might be chosen as prime minister, as soon as you're in office, you have many individuals scheming to try to remove you again."
Key Factors Behind Frequent Changes
- Single-party rule restricts outside challenges
- Internal factional rivalries fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Government continuity stays elusive despite economic strength
