The nation on course to elect woman prime minister in landmark first
In the past twenty years, Japan has had more than 10 prime ministers.
Actually, a specialist likens assuming the nation's highest office to drinking from a "poisoned chalice".
But why does the country keep changing leaders? It's due in part of it being a "single-party system", says Prof James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry originates inside the party, instead of 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 leader, the moment you're in office, you have many individuals scheming to try to get you out again."
Key Factors Behind Frequent Changes
- Single-party rule limits external competition
- Party infighting fuel leadership contests
- The leadership role is often described as a "poisoned chalice"
- Government continuity remains elusive despite financial power
