Crucial Decisions By Small Towns and Villages: Why Did Some Municipalities Choose to Merge But Others Did Not During the Nationwide Wave of Municipal Mergers in Japan?

This article focuses on the nationwide wave of municipal consolidations in Japan that took place from 2003 to 2006 and examines why some municipalities merged but others did not. The central government did not legally force consolidations but instead provided municipalities with fiscal incentives. I argue that small municipalities were reluctant to merge because they would lose generous transfers from the central government as well as decision-making powers once they unified with their larger neighbors. Fiscal incentives by the central government significantly raised the cost of remaining intact and induced a large number of fiscally weak municipalities to merge.
