Japan on course to choose female prime minister in historic first
Over the last two decades, Japan has had more than 10 leaders.
Actually, a specialist compares taking up the nation's highest office to taking a "cursed cup".
But why does the country frequently replace prime ministers? It's due in part of it being a "one-party democracy", explains Professor James Brown of Temple University Japan.
The LDP's grip on the country's politics means the primary rivalry originates within the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within different factions - they all want their own clique to secure the leadership position."
"So even though you could be chosen as prime minister, the moment you're in power, you have many individuals manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits external competition
- Party infighting drive leadership contests
- The prime minister's position is often described as a "cursed position"
- Government continuity stays difficult to achieve despite economic strength
