The nation set to elect female prime minister in landmark first
Over the last two decades, Japan has had more than 10 prime ministers.
In fact, one expert likens assuming the country's highest office to drinking from a "poisoned chalice".
But why does the country frequently replace leaders? It's due in part of it being a "single-party system", says 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 inside the party, rather than from external parties.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own clique to secure the top job."
"So even though you could be selected as leader, the moment you're in power, you have dozens of people manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Internal factional rivalries fuel power struggles
- The prime minister's position is frequently called a "cursed position"
- Government continuity stays elusive despite financial power
