Overview (history, characteristics, attractions)
The Fossa Magna Museum (Itoigawa City, Niigata Prefecture) is a specialized museum where you can comprehensively learn about the Fossa Magna, the huge geological boundary that divides the Japanese archipelago into east and west, and the geology, topography, minerals, and fossils of the surrounding area. The museum clearly introduces the geological drama brought about by the Fossa Magna and the characteristics of minerals, including jade, mined around Itoigawa, through actual specimens, scale models, dioramas, video and explanatory panels, and interactive exhibits.
In cooperation with local geopark activities, there are explanations by experts and hands-on events (such as stone observation and stone processing experiences), making it an appealing event that can be enjoyed by anyone, from geology beginners to experts. A major feature is that you can understand the formation of the Japanese archipelago by "seeing" and "touching" it.
