The nation on course to elect female prime minister in historic first
Over the last two decades, Japan has had more than 10 leaders.
Actually, one expert likens taking up the nation's highest office to taking a "poisoned chalice".
But why does Japan keep changing prime ministers? It's due in part of it being a "one-party democracy", says Professor James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the main political competition originates within the party, instead of from external parties.
"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 Frequent Changes
- One-party dominance limits outside challenges
- Party infighting fuel leadership contests
- The leadership role is often described as a "cursed position"
- Government continuity remains difficult to achieve despite financial power
