This study evaluates dyadic representation, that is, the link between the policy preferences of the constituencies and their representatives in the Japanese Lower House (LH). More specifically, this study examines how the within-party variation in policy positions among party candidates corresponds with that across their districts. By examining a series of candidate surveys conducted between 2003 and 2012 as well as the local employment structure, this study maps the association between the policy preferences of constituencies and those of their district candidates for two major parties. Specifically, candidates were found to take more rural-oriented positions on economic policies when running in districts with rural employment structures, while there remained a clear difference between parties. Moreover, this study demonstrates that constituencies accord more votes to candidates who better represent their preferences, strengthening the link by electing those who fulfill the responsibility beyond their party label.
