But why does Japan keep changing prime ministers? It's due in part of it being a "one-party democracy", says Prof James Brown of Temple University Japan.

"Therefore inside the LDP there are intense conflicts within various groups - they all desire their own clique to secure the top job."
"So even though you might be chosen as prime minister, as soon as you're in office, you have many individuals manoeuvring to try to get you out again."

- Internal factional rivalries drive power struggles
- The leadership role is often described as a "cursed position"
