Japan set to choose female prime minister in landmark first
Over the last two decades, Japan has had over ten prime ministers.
In fact, one expert likens taking up the nation's highest office to drinking from a "poisoned chalice".
However, what is the reason does Japan keep changing prime ministers? It's due in part of it being a "one-party democracy", says Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the country's politics means the main political competition comes from inside the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all want their own faction to get the top job."
"Thus although you could be chosen as leader, the moment you're in power, you have dozens of people manoeuvring to try to get you out again."
Key Factors Behind Frequent Changes
- Single-party rule limits outside challenges
- Party infighting drive power struggles
- The leadership role is often described as a "cursed position"
- Government continuity stays difficult to achieve despite financial power
