Replication Data for: Old Party, New Tricks: Candidates, Parties, and LDP Dominance in Japan

In 2009, after decades of single party rule under the Liberal Democratic Party (LDP), Japan had its first taste of a real alteration of power. However, just three years later, the LDP regained control of government with no significant challenger in sight. Historically, LDP dominance is a common tale, but its resurgence in recent years poses a significant puzzle in Japanese politics. What exactly has contributed to the LDP’s return to power? In years past, the LDP’s strength has come from a combination of cash, clientelistic networks, and strong candidates, but recent research has found that Japanese politics has become more programmatic and party-focused. While LDP dominance since its return to power in 2012 can be attributed in part to its candidates, I find that the appeal of the party label has played a large role in securing the LDP’s large majorities.
