The nation set to elect woman prime minister in landmark first
Over the last two decades, Japan has had over ten leaders.
In fact, a specialist compares taking up the nation's highest office to drinking from a "cursed cup".
However, what is the reason does the country keep changing leaders? This is partly because of it being a "one-party democracy", explains Professor 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 opposition groups.
"Therefore inside the LDP there are vicious struggles within different factions - they all desire their own clique to secure the leadership position."
"Thus although you might be selected as prime minister, as soon as you're in power, you have many individuals scheming to try to get you out again."
Key Factors Behind Rapid Turnover
- Single-party rule restricts outside challenges
- Internal factional rivalries fuel power struggles
- The leadership role is frequently called a "cursed position"
- Government continuity stays difficult to achieve despite financial power
