The nation on course to choose female prime minister in landmark first
Over the last two decades, the country has had more than 10 prime ministers.
Actually, one expert compares taking up the nation's highest office to taking a "cursed cup".
However, what is the reason does the country keep changing prime ministers? This is partly because of it being a "one-party democracy", explains Prof James Brown of Temple University Japan.
The LDP's grip on the country's politics 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 secure the top job."
"Thus although you could be chosen as leader, as soon as you're in office, you have many individuals scheming to try to get you out again."
Key Factors Behind Rapid Turnover
- One-party dominance limits external competition
- Party infighting drive power struggles
- The prime minister's position is frequently called a "cursed position"
- Government continuity stays elusive despite economic strength
