The nation set to elect female prime minister in historic first
In the past twenty years, the country has seen more than 10 leaders.
Actually, a specialist compares assuming the country's top job to taking a "cursed cup".
But why does the country frequently replace prime ministers? This is partly because 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 main political competition originates inside the party, rather than from external parties.
"Therefore inside the LDP there are intense conflicts within different factions - they all desire their own faction to get the leadership position."
"Thus although you could be selected as leader, the moment you're in office, you have many individuals manoeuvring to try to remove you again."
Main Reasons Behind Frequent Changes
- Single-party rule limits outside challenges
- Party infighting drive leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Government continuity remains elusive despite economic strength
