The nation on course to choose female prime minister in historic first
In the past twenty years, Japan has seen more than 10 prime ministers.
Actually, a specialist compares assuming the nation's top job to taking a "cursed cup".
However, what is the reason does Japan frequently replace prime ministers? This is partly because 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, rather than from external parties.
"So within the LDP there are vicious struggles within different factions - they all want their own clique to get the leadership position."
"So even though you might be selected as prime minister, the moment you're in power, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Rapid Turnover
- Single-party rule limits outside challenges
- Internal factional rivalries drive power struggles
- The prime minister's position is often described as a "cursed position"
- Government continuity remains elusive despite financial power
