The nation on course to choose female prime minister in landmark first
Over the last two decades, the country has had over ten prime ministers.
Actually, one expert likens assuming the country's top job to taking a "poisoned chalice".
However, what is the reason does the country frequently replace leaders? This is partly because of it being a "one-party democracy", explains Professor James Brown of Temple University Japan.
The LDP's grip on the political landscape means the primary rivalry comes from within the party, instead of from external parties.
"Therefore inside the LDP there are vicious struggles within different factions - they all desire their own faction to get the leadership position."
"So even though you might be chosen as leader, as soon as you're in power, you have many individuals manoeuvring to try to remove you again."
Main Reasons Behind Frequent Changes
- Single-party rule restricts external competition
- Party infighting drive leadership contests
- The prime minister's position is often described as a "poisoned chalice"
- Government continuity stays difficult to achieve despite economic strength
