Japan set to choose female prime minister in historic first
Over the last two decades, the country has seen over ten leaders.
In fact, one expert likens assuming the nation's top job to taking a "cursed cup".
However, what is the reason does Japan frequently replace leaders? It's due in part of it being a "single-party system", says Prof James Brown of Temple University Japan.
The LDP's grip on the political landscape means the main political competition originates within the party, rather than from opposition groups.
"So within the LDP there are intense conflicts within various groups - they all want their own faction to get the top job."
"Thus although you could be chosen as prime minister, the moment you're in office, you have many individuals manoeuvring to try to get you out again."
Key Factors Behind Rapid Turnover
- Single-party rule limits external competition
- Party infighting fuel power struggles
- The prime minister's position is often described as a "cursed position"
- Government continuity stays elusive despite economic strength
