The nation set to choose woman prime minister in landmark first
Over the last two decades, Japan has had over ten prime ministers.
Actually, a specialist compares assuming the country's top job to taking a "cursed cup".
However, what is the reason does Japan frequently replace prime ministers? It's due in part of it being a "one-party democracy", explains Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry comes from within the party, rather than from external parties.
"So within the LDP there are vicious struggles within different factions - they all want their own clique to secure the top job."
"So even though you could 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
- Single-party rule limits external competition
- Party infighting drive power struggles
- The leadership role is frequently called a "poisoned chalice"
- Political stability stays difficult to achieve despite financial power
