The nation set to elect female prime minister in landmark first
Over the last two decades, Japan has seen over ten leaders.
In fact, a specialist compares assuming the country's top job to drinking from a "poisoned chalice".
But why does Japan keep changing 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 main political competition originates inside the party, instead of from external parties.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own faction to get the top job."
"So even though you might be chosen as prime minister, the moment you're in power, you have many individuals manoeuvring to try to get you out again."
Key Factors Behind Frequent Changes
- Single-party rule limits outside challenges
- Party infighting fuel leadership contests
- The leadership role is frequently called a "poisoned chalice"
- Political stability remains elusive despite financial power
