The nation on course to choose woman prime minister in historic first
Over the last two decades, Japan has seen more than 10 leaders.
In fact, a specialist likens assuming the country's top job 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 "single-party system", explains Professor James Brown of Temple University Japan.
The LDP's grip on the country's politics means the main political competition comes from inside the party, instead of from external parties.
"Therefore inside the LDP there are intense conflicts within different factions - they all desire their own clique to get the leadership position."
"Thus although you could be chosen as prime minister, the moment you're in office, you have many individuals manoeuvring to try to get you out again."
Main Reasons Behind Frequent Changes
- One-party dominance restricts outside challenges
- Internal factional rivalries drive power struggles
- The leadership role is often described as a "poisoned chalice"
- Political stability remains elusive despite financial power
