The nation set to choose female prime minister in landmark first
In the past twenty years, the country has had over ten leaders.
Actually, a specialist likens assuming the nation's highest office to taking a "poisoned chalice".
However, what is the reason does the country keep changing prime ministers? This is partly because of it being a "one-party democracy", says Prof James Brown of Temple University Japan.
The LDP's grip on the country's politics means the main political competition comes from within the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all desire their own clique to get the leadership position."
"So even though you might be selected as prime minister, as soon as you're in office, you have many individuals manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- Single-party rule limits outside challenges
- Internal factional rivalries fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Political stability remains difficult to achieve despite economic strength
