The nation on course to choose woman prime minister in landmark first
In the past twenty years, Japan has had over ten prime ministers.
In fact, one expert likens taking up the nation'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 "single-party system", says Professor James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the primary rivalry comes from within the party, rather than from opposition groups.
"Therefore inside the LDP there are vicious struggles within different factions - they all desire their own faction to secure the leadership position."
"So even though you could be selected as prime minister, the moment you're in office, you have many individuals scheming to try to remove you again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits outside challenges
- Party infighting drive power struggles
- The leadership role is often described as a "poisoned chalice"
- Government continuity stays elusive despite economic strength
