The nation set to choose woman prime minister in historic first
In the past twenty years, Japan has seen more than 10 leaders.
In fact, one expert compares assuming the country's top job to taking a "poisoned chalice".
However, what is the reason does Japan keep changing prime ministers? It's due in part of it being a "one-party democracy", says Prof James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the primary rivalry comes from within the party, rather than 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 might be chosen as leader, the moment you're in power, you have many individuals manoeuvring to try to remove you again."
Main Reasons Behind Frequent Changes
- Single-party rule restricts external competition
- Internal factional rivalries drive power struggles
- The leadership role is frequently called a "cursed position"
- Government continuity stays elusive despite economic strength
