The nation set to elect woman prime minister in landmark first
In the past twenty years, the country has seen more than 10 prime ministers.
Actually, one expert compares taking up the country's top job to drinking from a "cursed cup".
But why does the country keep changing prime ministers? This is partly because of it being a "single-party system", says Prof James Brown of Temple University in Japan.
The LDP's grip on the country's politics means the main political competition comes from within the party, instead of from opposition groups.
"Therefore inside the LDP there are intense conflicts within different factions - they all want their own faction to secure the top job."
"So even though you could be chosen as prime minister, as soon as you're in office, you have many individuals scheming to try to remove you again."
Main Reasons Behind Rapid Turnover
- One-party dominance limits outside challenges
- Party infighting fuel leadership contests
- The prime minister's position is frequently called a "cursed position"
- Political stability stays difficult to achieve despite economic strength
