The nation set to choose female prime minister in landmark first
Over the last two decades, Japan has had over ten prime ministers.
Actually, a specialist likens assuming the country's top job to drinking from a "cursed cup".
But why does the country frequently replace leaders? It's due in part of it being a "one-party democracy", says Professor James Brown of Temple University Japan.
The LDP's grip on the political landscape means the main political competition comes from within the party, instead of from external parties.
"So within the LDP there are intense conflicts within different factions - they all want their own clique to secure the leadership position."
"Thus although you might be chosen as leader, as soon as you're in power, you have dozens of people scheming to try to remove you again."
Main Reasons Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Internal factional rivalries fuel power struggles
- The leadership role is frequently called a "poisoned chalice"
- Government continuity remains difficult to achieve despite economic strength
