The nation set to elect female prime minister in landmark first
Over the last two decades, Japan has had more than 10 prime ministers.
Actually, one expert compares assuming the country's highest office to taking a "cursed cup".
However, what is the reason does Japan keep changing prime ministers? This is partly because of it being a "one-party democracy", says Professor James Brown of Temple University Japan.
The Liberal Democratic Party's control on the country's politics means the primary rivalry comes from within the party, instead of from external parties.
"So within the LDP there are intense conflicts within different factions - they all want their own faction to get the top job."
"So even though you might be selected as prime minister, the moment you're in power, you have dozens of people scheming to try to get you out again."
Main Reasons Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Internal factional rivalries fuel power struggles
- The prime minister's position is often described as a "poisoned chalice"
- Political stability remains difficult to achieve despite economic strength
