The nation on course to elect woman prime minister in landmark first
Over the last two decades, the country has seen over ten leaders.
Actually, one expert likens taking up the nation's highest office to taking a "cursed cup".
However, what is the reason does the country frequently replace leaders? It's due in part of it being a "single-party system", explains Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry comes from within the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all desire their own faction to get the top job."
"So even though you might be chosen as prime minister, the moment you're in power, you have dozens of people scheming to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits outside challenges
- Party infighting fuel leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Government continuity remains difficult to achieve despite economic strength
