Japan on course to elect woman prime minister in landmark first
Over the last two decades, Japan has had more than 10 prime ministers.
Actually, one expert compares assuming the nation's highest office to taking a "poisoned chalice".
But why does Japan frequently replace prime ministers? This is partly because of it being a "one-party democracy", explains Prof James Brown of Temple University Japan.
The LDP's grip on the political landscape means the primary rivalry originates within the party, instead of from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own faction to get the top job."
"So even though you could be selected as leader, the moment you're in office, you have dozens of people manoeuvring to try to get you out again."
Key Factors Behind Rapid Turnover
- One-party dominance limits outside challenges
- Party infighting drive leadership contests
- The prime minister's position is often described as a "poisoned chalice"
- Government continuity remains elusive despite financial power
