This dissertation examines the governance structures for regional revitalisation in Japan, analysing how the interplay between national, prefectural, and municipal levels shapes rural revitalisation strategies. Employing a comparative multi-site case study methodology, this research explores the roles and interactions among different levels of governance in the national government (Tokyo), Fukuoka and Nagasaki Prefectures, Buzen City, and Hasami Town. It argues that Japan's approach to regional development is shifting towards a collaborative governance model that integrates multiple governmental tiers and stakeholders. Thus, the discussion on Japan’s governance should move beyond the traditional centralisation-decentralisation paradigm and should also be considered within the collaborative governance framework. This study contributes to the literature by showing the evolution of governance models and rural revitalisation strategies in Japan after the enactment of the 2014 Regional Revitalisation Law, and discussing their implications for policy and practice. The research underscores the potential of collaborative governance to enhance regional revitalisation efforts. The conclusion points to the need for further research into the balance of power within these governance models and their long-term impacts on rural development.
