1 - Introduction

Summary

This chapter presents an overview of the book’s theory, empirics, and contributions to the study of Japanese politics. The theory is in two parts. First, I make the case that when politicians run for office in electoral districts divisible into groups of voters, from whom electoral support is discernible and to whom central government resources are deliverable, they can pull those groups into clientelistic exchanges, in which the amount of money groups receive is tied to how they vote. Second, I consider the nuts and bolts of how a politician can go about tying a group’s resource allocation to its electoral support. I elucidate one method that politicians in a dominant party will be able to use. The chapter then presents an overview of the empirical strategy used to test the theory, which uses regression analyses of original data on resource allocations and voting behavior in Japanese municipalities, 1980–2014, buttressed by qualitative evidence. Finally, the chapter presents a summary of the headline findings for scholars of Japanese politics. Ultimately, the book helps to account for why a single party, Japan’s Liberal Democratic Party (LDP), has been able to win almost every election in Japan.
