The nation set to elect female prime minister in landmark first
In the past twenty years, Japan has had over ten prime ministers.
In fact, a specialist likens assuming the country's top job to drinking from a "cursed cup".
But why does Japan frequently replace 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 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 want their own faction to get the top job."
"Thus although you could be chosen as prime minister, the moment you're in office, you have many individuals scheming to try to remove you again."
Key Factors Behind Rapid Turnover
- Single-party rule limits external competition
- Party infighting drive power struggles
- The prime minister's position is frequently called a "cursed position"
- Government continuity remains elusive despite financial power
