Japan on course to choose female prime minister in historic first
Over the last two decades, Japan has seen more than 10 leaders.
In fact, a specialist compares taking up the country's highest office to taking a "cursed cup".
However, what is the reason does Japan frequently replace leaders? This is partly because of it being a "single-party system", explains Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the political landscape means the main political competition comes from inside the party, rather than from external parties.
"So within the LDP there are intense conflicts within different factions - they all desire their own faction to get the top job."
"So even though you could be chosen as prime minister, the moment you're in office, you have dozens of people scheming to try to get you out again."
Main Reasons Behind Rapid Turnover
- One-party dominance limits outside challenges
- Party infighting fuel leadership contests
- The prime minister's position is often described as a "cursed position"
- Political stability stays elusive despite financial power
