The nation on course to elect woman prime minister in historic first
In the past twenty years, the country has had more than 10 leaders.
In fact, a specialist compares assuming the nation's highest office to drinking from a "cursed cup".
However, what is the reason does Japan keep changing leaders? This is partly because of it being a "single-party system", explains Professor James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry comes from inside the party, rather than from external parties.
"Therefore inside the LDP there are intense conflicts within various groups - they all desire their own clique to secure the leadership position."
"So even though you could be selected as prime minister, as soon as you're in power, you have dozens of people scheming to try to remove you again."
Main Reasons Behind Rapid Turnover
- Single-party rule restricts external competition
- Party infighting fuel leadership contests
- The leadership role is often described as a "cursed position"
- Political stability stays difficult to achieve despite financial power
