Japan on course to elect female prime minister in landmark first
Over the last two decades, Japan has seen over ten leaders.
In fact, a specialist likens assuming the nation's highest office to taking a "cursed cup".
However, what is the reason does Japan frequently replace leaders? 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 country's politics means the main political competition originates within the party, rather than from external parties.
"So within the LDP there are intense conflicts within various groups - they all want their own clique to secure the top job."
"So even though you might be selected as prime minister, as soon as you're in office, you have many individuals manoeuvring to try to remove you again."
Main Reasons Behind Rapid Turnover
- One-party dominance limits outside challenges
- Party infighting drive leadership contests
- The prime minister's position is often described as a "poisoned chalice"
- Government continuity remains difficult to achieve despite financial power
