The nation on course to elect woman prime minister in landmark first
Over the last two decades, Japan has had over ten leaders.
In fact, a specialist likens taking up the country's top job to taking a "poisoned chalice".
However, what is the reason does Japan frequently replace leaders? This is partly because of it being a "one-party democracy", explains Professor James Brown of Temple University Japan.
The Liberal Democratic Party's control on the political landscape means the main political competition comes from inside the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within different factions - they all want their own clique to secure the leadership position."
"Thus although you could be chosen as prime minister, the moment you're in office, you have dozens of people manoeuvring to try to remove you again."
Main Reasons Behind Frequent Changes
- One-party dominance limits external competition
- Party infighting fuel power struggles
- The leadership role is frequently called a "cursed position"
- Political stability stays difficult to achieve despite financial power
