Japan on course to choose female prime minister in historic first
Over the last two decades, the country has seen more than 10 leaders.
Actually, one expert compares assuming the country's top job 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 Professor James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the main political competition comes from inside the party, rather than from external parties.
"So within the LDP there are vicious struggles within different factions - they all want their own faction to get the top job."
"Thus although you might be chosen as prime minister, the moment you're in power, you have many individuals scheming to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule restricts outside challenges
- Internal factional rivalries drive power struggles
- The prime minister's position is often described as a "cursed position"
- Government continuity remains difficult to achieve despite financial power
