The nation on course to choose woman prime minister in historic first
Over the last two decades, Japan has had over ten prime ministers.
Actually, a specialist compares taking up the nation's highest office to drinking from a "cursed cup".
But why does the country frequently replace leaders? This is partly because of it being a "one-party democracy", explains Professor James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the primary rivalry originates within the party, rather than from external parties.
"So within the LDP there are vicious struggles within different factions - they all desire their own clique to secure the leadership position."
"So even though you could be chosen as prime minister, as soon as you're in power, you have many individuals manoeuvring to try to get you out again."
Key Factors Behind Rapid Turnover
- Single-party rule restricts external competition
- Internal factional rivalries drive power struggles
- The prime minister's position is often described as a "cursed position"
- Government continuity remains difficult to achieve despite financial power
