The nation on course to elect woman prime minister in historic first
In the past twenty years, the country has had more than 10 prime ministers.
Actually, one expert likens assuming the nation's highest office to taking a "cursed cup".
However, what is the reason does the country keep changing leaders? It's due in part of it being a "one-party democracy", says Prof James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry comes from inside the party, rather than from opposition groups.
"So within the LDP there are intense conflicts within different factions - they all desire their own faction to get the top job."
"Thus although you could be chosen as prime minister, as soon as you're in power, you have many individuals scheming to try to get you out again."
Key Factors Behind Rapid Turnover
- Single-party rule restricts external competition
- Internal factional rivalries fuel leadership contests
- The prime minister's position is frequently called a "poisoned chalice"
- Government continuity remains elusive despite economic strength
