This paper deals with small and micro hydropower in Japan. After the Great East Japan Earthquake of March 2011 and the nuclear accident in Fukushima, renewable energy attracted great attention as a possible solutions to climate change, greenhouse gas (GHG) emissions and revitalize the local communities with natural capital management at the local level. Historically, hydropower (especially small scale) improved with community-based technology as an appropriate technology. In this paper, we tried to analyze some barriers to small hydropower development in Japan. In the current situation, some countries face similar problems (the problems of aging and depopulation community, economic dependence, liberalization of electricity, energy mixed system etc.) to Japan. The experience we have described from Japan may be of relevance to these countries.
