The nation set to elect female prime minister in historic first
Over the last two decades, the country has seen more than 10 leaders.
In fact, one expert likens taking up the country's highest office to taking a "cursed cup".
But why does the country frequently replace 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 political landscape means the primary rivalry comes from inside the party, rather than from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own faction 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 manoeuvring to try to remove you again."
Main Reasons Behind Rapid Turnover
- One-party dominance limits outside challenges
- Party infighting fuel power struggles
- The leadership role is frequently called a "cursed position"
- Government continuity stays elusive despite financial power
