Japan on course to elect female prime minister in landmark first
Over the last two decades, the country has had more than 10 leaders.
In fact, one expert compares assuming the nation's top job to taking a "cursed cup".
However, what is the reason does Japan frequently replace prime ministers? It's due in part of it being a "single-party system", explains Prof 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.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own clique to secure the top job."
"Thus although you might be chosen as prime minister, as soon as you're in power, you have dozens of people scheming to try to get you out again."
Key Factors Behind Frequent Changes
- One-party dominance limits outside challenges
- Party infighting fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Government continuity stays elusive despite economic strength
