Japan set to choose female prime minister in landmark first
Over the last two decades, the country has seen more than 10 leaders.
Actually, one expert compares taking up the nation's highest office to taking a "poisoned chalice".
However, what is the reason does Japan frequently replace leaders? It's due in part of it being a "one-party democracy", says Professor James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the country's politics means the main political competition originates within the party, instead of from external parties.
"So within the LDP there are vicious struggles within different factions - they all want their own clique to secure the leadership position."
"Thus although you might be selected as leader, the moment you're in office, you have dozens of people manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits outside challenges
- Internal factional rivalries drive power struggles
- The leadership role is often described as a "poisoned chalice"
- Government continuity stays elusive despite economic strength
