Geopark is a beneficial tool for regional development that makes use of characteristic natural and cultural resources, such as landform, rocks, animals, and plants, as well as human history, culture, and traditions in an area. Geopark as a system includes promoting regional development based on integrating three fundamental elements of geopark activity, i.e., conservation, education, and geotourism. Itoigawa Geopark was designated a member of the Global Geopark Network with assistance from UNESCO on 22 August 2009. Itoigawa is a small city with a population of about 48,000 located on the coast of the Japan Sea close to mountains. Following its recognition, the citizens of Itoigawa became aware of the international excellence of the nature and culture of the city and developed pride in their hometown. Consequently, work began to construct a new community by promoting the region based on the geopark system. The awareness of the citizens generated the spontaneous ideas and actions needed to construct a comfortable life with good health, education, and economy in the city. Local governments, such as those of cities, towns, and villages, especially in rural areas, have been looking for ways to promote their regions because of Japan's weak economy over the past twenty years. The geopark is expected to be a useful tool for achieving significant regional development in rural areas.
