The nation set to elect woman prime minister in historic first
Over the last two decades, the country has seen over ten leaders.
In fact, a specialist likens assuming the nation's top job to taking a "cursed cup".
But why does Japan keep changing leaders? It's due in part of it being a "one-party democracy", says Professor James Brown of Temple University Japan.
The LDP's grip on the country's politics means the primary rivalry comes from within the party, rather than from opposition groups.
"So within the LDP there are vicious struggles within various groups - they all want their own faction to get the leadership position."
"So even though you could be selected as leader, the moment you're in office, you have dozens of people 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 frequently called a "cursed position"
- Government continuity remains difficult to achieve despite financial power
