The nation on course to choose woman prime minister in landmark first
In the past twenty years, the country has seen more than 10 leaders.
Actually, one expert likens taking up the nation's top job to taking a "poisoned chalice".
However, what is the reason does the country keep changing leaders? This is partly because of it being a "single-party system", explains Professor James Brown of Temple University in Japan.
The LDP's grip 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 intense conflicts within various groups - they all want their own faction to get the leadership position."
"So even though you might be chosen as leader, the moment you're in office, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- Single-party rule restricts outside challenges
- Party infighting fuel leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Government continuity remains elusive despite economic strength
