The nation set to choose woman prime minister in landmark first
In the past twenty years, Japan has had over ten prime ministers.
Actually, a specialist compares assuming the country's highest office to taking a "poisoned chalice".
But why does Japan frequently replace leaders? It's due in part of it being a "one-party democracy", says Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the political landscape means the main political competition comes from within the party, rather than from opposition groups.
"Therefore inside the LDP there are intense conflicts within various groups - they all desire their own clique to get the leadership position."
"Thus although you could be chosen as leader, the moment you're in office, you have many individuals scheming to try to get you out again."
Key Factors Behind Frequent Changes
- One-party dominance limits external competition
- Internal factional rivalries fuel leadership contests
- The leadership role is often described as a "poisoned chalice"
- Political stability remains elusive despite financial power
