Japan set to choose woman prime minister in historic first
Over the last two decades, the country has had more than 10 leaders.
In fact, a specialist compares assuming the nation's highest office to taking a "poisoned chalice".
But why does Japan frequently replace prime ministers? It's due in part of it being a "one-party democracy", says Professor James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry comes from within the party, rather than from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all want their own faction to secure the leadership position."
"Thus although you could be selected as prime minister, the moment you're in power, you have dozens of people scheming to try to remove you again."
Main Reasons Behind Rapid Turnover
- One-party dominance limits external competition
- Party infighting drive power struggles
- The leadership role is frequently called a "poisoned chalice"
- Political stability stays elusive despite economic strength
