Japan set to elect female prime minister in landmark first
Over the last two decades, Japan has seen more than 10 leaders.
In fact, one expert compares assuming the nation's highest office to taking a "poisoned chalice".
But why does Japan keep changing 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 political landscape means the main political competition comes from within 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 secure the top job."
"So even though you might be chosen as leader, as soon as you're in power, you have many individuals manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- One-party dominance restricts outside challenges
- Party infighting drive power struggles
- The prime minister's position is often described as a "cursed position"
- Political stability remains difficult to achieve despite financial power
