Over the last two decades, Japan has seen over ten prime ministers.
Actually, one expert likens assuming the country's highest office to taking a "poisoned chalice".
But why does Japan frequently replace prime ministers? This is partly because of it being a "single-party system", explains Prof James Brown of Temple University Japan.
The LDP's grip on the country's politics means the primary rivalry originates inside the party, instead of from opposition groups.
"Therefore inside the LDP there are vicious struggles within various groups - they all desire their own clique to secure the leadership position."
"Thus although you might 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 Frequent Changes
- Single-party rule restricts external competition
- Party infighting drive power struggles
- The leadership role is often described as a "poisoned chalice"
- Political stability stays difficult to achieve despite economic strength
