Japan on course to elect woman prime minister in landmark first
Over the last two decades, the country has seen more than 10 leaders.
In fact, one expert compares assuming the nation's highest office to drinking from a "poisoned chalice".
However, what is the reason does the country frequently replace prime ministers? It's due in part of it being a "one-party democracy", explains Professor James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry comes from inside the party, instead of from external parties.
"Therefore inside the LDP there are vicious struggles within different factions - they all want their own faction to secure the leadership position."
"So even though you could be chosen as prime minister, the moment you're in power, 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 drive leadership contests
- The leadership role is often described as a "poisoned chalice"
- Political stability stays elusive despite financial power
