The nation set to choose woman prime minister in landmark first
Over the last two decades, Japan has had over ten leaders.
Actually, a specialist compares assuming the nation's top job to taking a "cursed cup".
But why does Japan frequently replace prime ministers? This is partly because 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 vicious struggles within various groups - they all want their own clique to get the leadership position."
"Thus although you might be chosen as prime minister, as soon as you're in power, you have many individuals scheming to try to remove you again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits outside challenges
- Internal factional rivalries drive power struggles
- The leadership role is frequently called a "cursed position"
- Political stability remains difficult to achieve despite financial power
