Fossa Magna Museum / フォッサマグナミュージアム
Itoigawa City is located directly above the Itoigawa Shizuoka Tectonic Line, where you can observe a wide variety of rocks, minerals, and geological structures. The Fossa Magna Museum opened on April 25, 1994, taking advantage of these regional characteristics.
It is an exhibition that allows you to learn about the evolution of the earth, focusing on exhibits related to Fossa Magna that extends from Itoigawa to the east, as well as minerals, fossils, and rocks from Itoigawa and the surrounding areas. Large jade gemstones are lined up outdoors, and the types and forms of the collection are various. You can also see the Wehert seismometer in operation.
In addition to a museum shop that handles mineral specimens, there is a service that is charged for the creation of rock specimens (slices), but it is a valuable facility for amateur mineral researchers.
From September 8, 2014, it was closed due to the renewal of the exhibition room, but it was reopened on March 9, 2015 in conjunction with the opening of Itoigawa Station on March 14, 2015.
