The nation set to choose woman prime minister in historic first
Over the last two decades, Japan has had over ten leaders.
In fact, one expert compares taking up the country's highest office to taking a "cursed cup".
However, what is the reason does Japan keep changing prime ministers? This is partly because of it being a "single-party system", explains Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry comes from 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 secure the leadership position."
"So even though you might be chosen as leader, the moment you're in power, you have dozens of people scheming to try to get you out again."
Key Factors Behind Frequent Changes
- One-party dominance limits external competition
- Party infighting drive leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Political stability remains elusive despite economic strength
