The nation set to choose woman prime minister in landmark first
In the past twenty years, Japan has seen more than 10 leaders.
Actually, a specialist likens taking up the country's highest office to taking a "poisoned chalice".
However, what is the reason does Japan keep changing prime ministers? This is partly because of it being a "single-party system", 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, rather than from external parties.
"Therefore inside the LDP there are vicious struggles within different factions - they all want their own clique to secure the leadership position."
"So even though you might be chosen as leader, as soon as you're in office, you have dozens of people scheming to try to remove you again."
Main Reasons 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 remains elusive despite economic strength
