Japan on course to elect female prime minister in historic first
In the past twenty years, the country has had more than 10 prime ministers.
In fact, a specialist likens assuming the nation's top job to drinking from a "cursed cup".
However, what is the reason does Japan frequently replace prime ministers? This is partly because of it being a "single-party system", says Professor James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the main political competition 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 get the leadership position."
"Thus although you might be chosen as prime minister, the moment you're in office, you have many individuals scheming to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits external competition
- Internal factional rivalries drive power struggles
- The prime minister's position is often described as a "poisoned chalice"
- Political stability stays elusive despite financial power
