The nation set to elect female prime minister in historic first
Over the last two decades, the country has had over ten prime ministers.
In fact, a specialist likens taking up the country's highest office to taking a "poisoned chalice".
However, what is the reason does the country 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 main political competition originates inside the party, instead of from external parties.
"So within the LDP there are intense conflicts within different factions - they all desire their own faction to get the leadership position."
"So even though you might be selected as leader, as soon as you're in power, you have many individuals scheming to try to get you out again."
