The nation on course to elect female prime minister in landmark first
Over the last two decades, the country has seen over ten prime ministers.
In fact, one expert likens assuming the country's highest office to drinking from a "poisoned chalice".
However, what is the reason does Japan frequently replace prime ministers? This is partly because of it being a "one-party democracy", says Professor James Brown of Temple University in Japan.
The Liberal Democratic Party's control on the political landscape means the primary rivalry comes from inside the party, instead of from opposition groups.
"So within the LDP there are intense conflicts within various groups - they all desire their own clique to get the top job."
"So even though you might be chosen as leader, the moment you're in office, you have dozens of people manoeuvring to try to get you out again."
Main Reasons Behind Rapid Turnover
- One-party dominance restricts outside challenges
- Party infighting fuel power struggles
- The leadership role is often described as a "poisoned chalice"
- Political stability stays elusive despite financial power
