Japan set to choose woman prime minister in landmark first
Over the last two decades, the country has had over ten prime ministers.
In fact, a specialist likens assuming the country's top job to taking a "cursed cup".
However, what is the reason does Japan frequently replace prime ministers? It's due in part of it being a "single-party system", says Prof James Brown of Temple University Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry comes from within the party, rather than from opposition groups.
"Therefore inside the LDP there are intense conflicts within different factions - they all want their own clique to secure the leadership position."
"Thus although you could be chosen as prime minister, as soon as you're in power, you have dozens of people manoeuvring to try to remove you again."
Key Factors Behind Frequent Changes
- Single-party rule restricts outside challenges
- Party infighting drive power struggles
- The prime minister's position is frequently called a "poisoned chalice"
- Government continuity stays elusive despite economic strength
