Geographical indications (GIs) have recently become an important tool for Japanese agricultural policy, particularly after the adoption of a “sui generis” certification system in 2015. In the same year, the United Nations proposed a common agenda with 17 Sustainable Development Goals (SDGs). The present paper addresses the potential of GIs to enhance SDGs in Japan. First, we examine existing knowledge on GI inception, which consists in both government reports and research surveys. We show that these studies mostly focus on SDGs related to economic growth, and on social issues raised by the registration process. Then, as an exploration of potential impacts of GIs on the full set of SDGs, we study the case of Mishima Bareisho Potato GI, on the basis of interviews and participatory observation. From local stakeholders’ point of view, Mishima Potato GI can contribute to at least nine SDGs at all the production, transformation and commercialization stages. The SDG framework is useful to reveal some contributions seldomly considered in GI studies but which matter for local people, for example, the employment of disabled people or nutritional education. Finally, we discuss how these new insights can contribute to the debate on the potential role and limits of GIs for sustainable development in Japan.
