The nation set to choose woman prime minister in historic first
In the past twenty years, the country has had over ten leaders.
Actually, a specialist compares assuming the nation's top job to taking a "cursed cup".
But why does the country frequently replace prime ministers? It's due in part of it being a "one-party democracy", explains Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the political landscape means the main political competition originates inside the party, instead of from opposition groups.
"So within the LDP there are intense conflicts within various groups - they all want their own clique to get the top job."
"Thus although you might be chosen as prime minister, as soon as you're in power, you have dozens of people manoeuvring to try to get you out again."
Key Factors Behind Rapid Turnover
- Single-party rule limits outside challenges
- Party infighting fuel power struggles
- The prime minister's position is often described as a "cursed position"
- Government continuity remains difficult to achieve despite financial power
