The nation on course to elect woman prime minister in historic first
Over the last two decades, Japan has had over ten prime ministers.
In fact, a specialist likens taking up the country's top job to taking a "cursed cup".
However, what is the reason does Japan keep changing prime ministers? It's due in part of it being a "one-party democracy", says Professor James Brown of Temple University Japan.
The LDP's grip on the political landscape means the main political competition comes from inside the party, instead of from external parties.
"Therefore inside the LDP there are intense conflicts within various groups - they all desire their own clique to get the leadership position."
"Thus although you could be chosen as prime minister, the moment you're in office, you have dozens of people scheming to try to get you out again."
Key Factors Behind Rapid Turnover
- One-party dominance limits outside challenges
- Party infighting drive power struggles
- The prime minister's position is frequently called a "cursed position"
- Government continuity stays elusive despite economic strength
