The nation set to elect female prime minister in historic first
Over the last two decades, the country has seen over ten leaders.
In fact, a specialist compares taking up the nation's highest office to drinking from a "cursed cup".
However, what is the reason does the country keep changing prime ministers? This is partly because of it being a "single-party system", explains Professor James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry comes from inside the party, instead of from opposition groups.
"So within the LDP there are intense conflicts within different factions - they all desire their own clique to secure the top job."
"So even though you could be chosen as leader, as soon as you're in power, you have many individuals manoeuvring to try to get you out again."
Main Reasons Behind Frequent Changes
- Single-party rule restricts outside challenges
- Internal factional rivalries drive power struggles
- The prime minister's position is frequently called a "cursed position"
- Political stability remains difficult to achieve despite financial power
