Japan set to choose woman prime minister in historic first
Over the last two decades, the country has had over ten leaders.
Actually, one expert likens taking up the country'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 Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry originates inside the party, instead of 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."
"So even though you could be chosen as prime minister, the moment you're in power, you have many individuals scheming to try to get you out again."
Key Factors Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Party infighting drive leadership contests
- The prime minister's position is often described as a "cursed position"
- Political stability stays elusive despite financial power
