The International ONSEN Summit is the world's first international conference on ONSEN where participants exchange information and engage in discussion on the use of ONSEN resources and the potential for regional development. Participants in the Summit included leaders and researchers from ONSEN areas in Japan and around the world. Following a keynote speech and case study speeches, more in-depth discussion in three distinct areas was had by separate working groups, and as a final result of that debate, the International ONSEN Summit Declaration was adopted.
