Japan set to elect woman prime minister in historic first
Over the last two decades, Japan has seen more than 10 leaders.
In fact, a specialist likens taking up the nation's highest office to taking a "cursed cup".
However, what is the reason does the country keep changing prime ministers? This is partly because of it being a "single-party system", says Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry originates within the party, rather than from external parties.
"Therefore inside the LDP there are intense conflicts within different factions - they all desire their own clique to secure the leadership position."
"Thus although you could be chosen as prime minister, the moment you're in office, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- One-party dominance restricts outside challenges
- Party infighting drive power struggles
- The leadership role is often described as a "cursed position"
- Political stability stays elusive despite financial power
