The nation on course to elect woman prime minister in historic first
Over the last two decades, the country has seen more than 10 leaders.
Actually, one expert likens assuming the nation's highest office to taking a "poisoned chalice".
However, what is the reason does Japan frequently replace prime ministers? It's due in part of it being a "single-party system", explains Prof James Brown of Temple University Japan.
The LDP's grip on the political landscape means the main political competition comes from inside the party, instead of from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own faction to secure the top job."
"Thus although you might be selected as leader, the moment you're in office, you have dozens of people manoeuvring to try to remove you again."
Main Reasons Behind Frequent Changes
- Single-party rule restricts external competition
- Internal factional rivalries fuel power struggles
- The prime minister's position is often described as a "poisoned chalice"
- Government continuity stays difficult to achieve despite financial power
