The nation on course to elect woman prime minister in historic first
Over the last two decades, Japan has had over ten leaders.
Actually, a specialist compares taking up the country's top job to drinking from a "poisoned chalice".
But why does the country frequently replace leaders? This is partly because of it being a "one-party democracy", says Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry originates within the party, instead of from external parties.
"So within the LDP there are intense conflicts within various groups - they all want their own clique to secure the leadership position."
"So even though you could be chosen as prime minister, the moment you're in office, you have dozens of people scheming to try to remove you again."
Key Factors Behind Frequent Changes
- Single-party rule limits outside challenges
- Party infighting fuel leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Government continuity stays elusive despite financial power
