Japan on course to elect woman prime minister in landmark first
In the past twenty years, Japan has seen more than 10 leaders.
In fact, a specialist compares assuming the nation's highest office to drinking from a "cursed cup".
But why does Japan frequently replace prime ministers? This is partly because of it being a "single-party system", explains Professor James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the main political competition originates within the party, instead of from opposition groups.
"So within the LDP there are intense conflicts within different factions - they all want their own clique to get the leadership position."
"So even though you could be chosen as prime minister, the moment you're in office, you have dozens of people manoeuvring to try to get you out again."
Key Factors Behind Frequent Changes
- One-party dominance restricts external competition
- Internal factional rivalries fuel leadership contests
- The prime minister's position is frequently called a "poisoned chalice"
- Political stability stays difficult to achieve despite economic strength
