Japan set to choose woman prime minister in historic first
Over the last two decades, the country has seen over ten leaders.
In fact, a specialist compares assuming the country's top job to drinking from a "cursed cup".
However, what is the reason does the country frequently replace leaders? This is partly because of it being a "one-party democracy", says Professor James Brown of Temple University in Japan.
The LDP's grip on the political landscape means the primary rivalry originates inside the party, rather than from opposition groups.
"So within the LDP there are intense conflicts within different factions - they all want their own clique to get the leadership position."
"Thus although you could be chosen as prime minister, the moment you're in power, you have many individuals manoeuvring to try to remove you again."
Main Reasons Behind Frequent Changes
- Single-party rule limits external competition
- Internal factional rivalries drive leadership contests
- The prime minister's position is often described as a "poisoned chalice"
- Political stability remains difficult to achieve despite financial power
