The nation set to choose female prime minister in historic first
In the past twenty years, Japan has seen more than 10 leaders.
In fact, one expert likens assuming the nation's top job to taking a "cursed cup".
But why 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 political landscape means the primary rivalry comes from within the party, rather than from opposition groups.
"Therefore inside the LDP there are vicious struggles within different factions - they all desire their own clique to secure the top job."
"So even though you might be chosen as leader, the moment you're in office, you have dozens of people scheming to try to get you out again."
Main Reasons Behind Frequent Changes
- One-party dominance restricts outside challenges
- Internal factional rivalries fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Government continuity stays elusive despite financial power
