Japan on course to elect female prime minister in historic first
Over the last two decades, the country has seen over ten prime ministers.
In fact, one expert compares assuming the nation's highest office to drinking from a "cursed cup".
But why does Japan frequently replace leaders? This is partly because of it being a "one-party democracy", says Prof James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry comes from inside the party, instead of from opposition groups.
"Therefore inside the LDP there are intense conflicts within various groups - they all desire their own faction to secure the leadership position."
"Thus although you might be chosen as leader, the moment you're in office, you have dozens of people scheming to try to get you out again."
Key Factors Behind Frequent Changes
- Single-party rule limits external competition
- Party infighting fuel power struggles
- The leadership role is frequently called a "poisoned chalice"
- Political stability stays elusive despite economic strength
