The nation set to elect woman prime minister in landmark first
In the past twenty years, Japan has had more than 10 leaders.
In fact, one expert likens assuming the country's top job to drinking from a "poisoned chalice".
However, what is the reason does Japan frequently replace prime ministers? It's due in part of it being a "single-party system", says Professor James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the political landscape means the main political competition originates inside the party, rather than from opposition groups.
"So within the LDP there are intense conflicts within various groups - they all desire their own clique to get the leadership position."
"So even though you could be selected as leader, the moment you're in power, you have dozens of people manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- Single-party rule limits external competition
- Party infighting fuel power struggles
- The prime minister's position is frequently called a "cursed position"
- Political stability remains elusive despite economic strength
