Japan on course to choose female prime minister in historic first
Over the last two decades, Japan has seen over ten leaders.
Actually, a specialist likens taking up the nation's highest office to drinking from a "cursed cup".
However, what is the reason does the country frequently replace prime ministers? It's due in part of it being a "single-party system", explains Professor James Brown of Temple University Japan.
The LDP's grip on the political landscape means the primary rivalry originates inside the party, instead of from opposition groups.
"So within the LDP there are intense conflicts within various groups - they all want their own clique to get the top job."
"So even though you might be chosen as leader, the moment you're in power, you have dozens of people manoeuvring to try to get you out again."
Key Factors Behind Rapid Turnover
- One-party dominance limits external competition
- Internal factional rivalries fuel leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Government continuity stays elusive despite financial power
