The nation set to elect female prime minister in landmark first
In the past twenty years, Japan has had more than 10 prime ministers.
In fact, one expert likens taking up the nation's highest office to taking a "poisoned chalice".
But why does the country frequently replace prime ministers? It's due in part of it being a "one-party democracy", explains Prof James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry 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 faction to secure the leadership position."
"Thus although you might be selected as prime minister, 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 leadership role is often described as a "poisoned chalice"
- Government continuity stays difficult to achieve despite economic strength
