Japan set to elect woman prime minister in historic first
Over the last two decades, Japan has had more than 10 leaders.
In fact, one expert compares assuming the country's top job to taking a "cursed cup".
However, what is the reason does the country keep changing prime ministers? This is partly because 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 comes from within the party, rather than from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all desire their own faction to secure the leadership position."
"Thus although you might be chosen as prime minister, as soon as you're in power, you have many individuals manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- One-party dominance restricts external competition
- Party infighting drive power struggles
- The prime minister's position is frequently called a "cursed position"
- Government continuity stays difficult to achieve despite economic strength
