Japan set to elect woman prime minister in landmark first
Over the last two decades, the country has seen over ten leaders.
In fact, a specialist compares taking up the nation's top job to drinking from a "poisoned chalice".
However, what is the reason does Japan keep changing leaders? It's due in part of it being a "single-party system", says Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the main political competition originates within the party, rather than from external parties.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own clique to get the top job."
"So even though you might be selected as prime minister, the moment you're in office, you have many individuals manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Party infighting drive leadership contests
- The leadership role is often described as a "poisoned chalice"
- Political stability stays elusive despite economic strength
