I am researching regional revitalization through sports tourism at facilities that utilize local natural capital and public goods. The area has capital that can be used as sports facilities such as sea, hills, rivers, waterfalls, earth lakes, parks, and roads. There are many in Okayama! In addition to large-scale facilities such as stadiums and arenas, we are working to create a playground by utilizing these regional capitals and to attract tourists from cities and overseas to the region.
