Recent research claims that local party organizations are essential for new parties seeking organizational stability and national-level electoral success. Yet new parties which emerged in Japan since the 1990s have failed in building nation-wide networks of local organizations. The article asks how these parties sought to expand locally and why their attempts have been largely unsuccessful. It finds evidence that under certain conditions (in urban areas and multi-member districts, or when controlling local chief executive offices and endowed with inherited resources) new parties have been more successful in standing and winning seats in regional elections. Regions with these favorable conditions are few, however, resulting in the overall weakness of the new parties’ local organizations. The study also disconfirms expectations that a party's control of national government should result in their improved representation at the local level. The article contributes to elucidating the incentives and dynamics of building party organizations in terms of local elected offices for newcomer parties in Japan. It hints at similar challenges for entrepreneurial parties with few social roots in other established democracies.
