The nation set to elect woman prime minister in landmark first
Over the last two decades, Japan has seen over ten leaders.
Actually, one expert likens taking up the nation's top job to taking a "cursed cup".
However, what is the reason does Japan keep changing prime ministers? It's due in part of it being a "one-party democracy", says Prof James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the main political competition originates inside the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within different factions - they all desire their own clique to secure 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
- One-party dominance limits outside challenges
- Internal factional rivalries fuel power struggles
- The prime minister's position is often described as a "poisoned chalice"
- Political stability remains difficult to achieve despite financial power
