The nation set to elect woman prime minister in historic first
Over the last two decades, Japan 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 Japan frequently replace leaders? This is partly because of it being a "one-party democracy", explains Prof James Brown of Temple University Japan.
The LDP's grip on the country's politics means the primary rivalry comes from within the party, instead of from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own faction to secure the leadership position."
"Thus although you could be chosen as prime minister, as soon as you're in power, you have many individuals scheming to try to remove you again."
Key Factors Behind Frequent Changes
- One-party dominance restricts outside challenges
- Party infighting fuel power struggles
- The prime minister's position is often described as a "cursed position"
- Government continuity stays elusive despite financial power
