By interviewing with Sumida ward assembly members and analyzing results of municipal assembly elections, this research confirms the effect of population size on the party affiliation.Determinants of party-centered campaigns in local assembly elections2008.042011.03political party, electoral institution, inconsistency of institutionDifferent electoral systems may cause different candidate competitions that are either centripetal or centrifugal. This research considers the organizational links between the competitions of candidates for General election and local assembly elections. We argue that centrifugal candidate competition at local assembly SNTV/MMD (single non-transferable vote/multi-member district) hinders the realization of the theoretical expectation that a candidate competition at SMD (single-member district) of the House of Representatives converges to the policy position of the median voter. We tested this "inconsistency of electoral systems" hypothesis by using aggregated election results (Horiuchi and Natori 2007), candidate's electoral platform data (Tsutsumi and Uekami 2007), field data (Yamada 2007), survey research data (Maeda 2007), and election outcomes of 15 countries (Nishikawa 2007). Overall results of these tests seem to be good. So we can conclude that we have to take linkage between national and local politics into consideration when we study effects of electoral systems upon party politics.Research on the impact of the electoral reform: the "inconsistency of electoral systems" hypothesis2004.042007.03

In conclusion, the 1994 electoral reform opened up the leadership selection process: the importance of leader images and the LDP organizational decline under SMD system accelerated the transformation of the selection process. In addition, the candidates for the LDP leadership beco me younger, have less experiences, and tend to be chosen from the urban constituencies as a result of these changes.
