Japan set to choose woman prime minister in landmark first
Over the last two decades, the country has had more than 10 leaders.
Actually, a specialist compares assuming the country's top job to drinking from a "cursed cup".
However, what is the reason does the country frequently replace 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.
"Therefore inside the LDP there are vicious struggles within different factions - they all want their own clique to secure the top job."
"So even though you might be selected as leader, as soon as you're in office, you have many individuals scheming to try to get you out again."
Key Factors Behind Frequent Changes
- Single-party rule restricts external competition
- Party infighting drive power struggles
- The prime minister's position is often described as a "cursed position"
- Political stability remains difficult to achieve despite economic strength
