The nation on course to elect female prime minister in historic first
Over the last two decades, the country has had over ten leaders.
In fact, one expert likens taking up the nation's highest office to drinking from a "cursed cup".
However, what is the reason does Japan keep changing leaders? It's due in part of it being a "one-party democracy", explains Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry originates within the party, rather than from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all want their own faction to secure the top job."
"Thus although you could be chosen as prime minister, the moment you're in power, you have many individuals scheming to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits 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
