Japan set to elect female prime minister in historic first
Over the last two decades, the country has seen over ten prime ministers.
In fact, a specialist likens taking up the country's highest office to taking a "cursed cup".
But why does the country frequently replace prime ministers? It's due in part of it being a "single-party system", explains Professor James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry originates inside the party, rather than from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all want their own clique to get the top job."
"Thus although you might be chosen as leader, the moment you're in power, you have many individuals manoeuvring to try to get you out again."
Key Factors Behind Frequent Changes
- One-party dominance restricts outside challenges
- Party infighting drive power struggles
- The leadership role is often described as a "cursed position"
- Government continuity remains difficult to achieve despite economic strength
