The nation on course to choose female prime minister in landmark first
In the past twenty years, Japan has seen more than 10 leaders.
Actually, a specialist likens taking up the nation's highest office 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", explains Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the country's politics means the main political competition originates inside the party, instead of from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all want their own clique to secure the top job."
"Thus although you might be chosen as prime minister, the moment you're in power, you have many individuals scheming to try to get you out again."
Main Reasons Behind Frequent Changes
- One-party dominance limits outside challenges
- Internal factional rivalries fuel leadership contests
- The prime minister's position is often described as a "cursed position"
- Government continuity stays difficult to achieve despite financial power
