The nation set to elect female prime minister in landmark first
In the past twenty years, the country has had over ten leaders.
In fact, one expert compares taking up the country's highest office to taking a "poisoned chalice".
But why does the country frequently replace prime ministers? It's due in part of it being a "single-party system", says 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 opposition groups.
"So within the LDP there are vicious struggles within different factions - they all desire their own clique to get the leadership position."
"So even though you might be chosen as prime minister, the moment you're in power, you have many individuals scheming to try to get you out again."
Main Reasons Behind Frequent Changes
- Single-party rule limits external competition
- Party infighting drive leadership contests
- The prime minister's position is frequently called a "poisoned chalice"
- Political stability stays elusive despite economic strength
