Japan on course to choose woman prime minister in historic first
In the past twenty years, Japan has seen more than 10 leaders.
In fact, a specialist likens taking up the nation's highest office to drinking from a "poisoned chalice".
But why does Japan frequently replace leaders? It's due in part 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 main political competition originates within the party, instead of from external parties.
"Therefore inside the LDP there are intense conflicts within different factions - they all want their own faction to get the top job."
"Thus although you could be selected as leader, the moment you're in office, you have many individuals manoeuvring to try to get you out again."
Main Reasons Behind Frequent Changes
- One-party dominance limits outside challenges
- Internal factional rivalries fuel power struggles
- The prime minister's position is frequently called a "cursed position"
- Political stability remains elusive despite financial power
