The nation on course to choose female prime minister in historic first
In the past twenty years, Japan has had over ten prime ministers.
Actually, a specialist likens taking up the nation's top job to drinking from a "poisoned chalice".
But why does the country keep changing prime ministers? This is partly because of it being a "one-party democracy", says Professor James Brown of Temple University Japan.
The LDP's grip on the country's politics means the primary rivalry originates inside the party, instead of from external parties.
"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 might be selected as leader, as soon as you're in power, you have many individuals manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- One-party dominance limits outside challenges
- Party infighting drive leadership contests
- The leadership role is often described as a "poisoned chalice"
- Political stability stays difficult to achieve despite economic strength
