Fossa Magna Museum
Explore the mysteries of the earth at the UNESCO Global Geopark's museum!

This is a rock museum within Itoigawa UNESCO Global Geopark, which includes the geology of both the Myoko-Togakushi renzan and Chubusangaku National Parks. Jade, the national stone of Japan, is a stone that tells a tale of the archipelago's birth. Fossa Magna and the Itoigawa-Shizuoka Tectonic Line, which divide the Japanese archipelago into its Western and Eastern halves, are fissures created when the archipelago separated from the Asian mainland. On your exploration of the land of the Itoigawa, the Fossa Magna Museum is worth a visit to learn about jade, the Fossa Magna, and more. An impressive theater and a variety of rock, mineral, and fossil specimens invite you into the mysterious world of this land.

Message from the Facility
If you are still of the belief that a rock is “just a rock,” you should know that each rock has a name, an age, and a birthplace, and that there is no such thing as “just a rock.” By learning about rocks, you become a time traveler on this earth. The banks of the Itoigawa consist of gravel. Stones abound in a variety of colors and patterns, with each stone telling the secrets of its birth. Come to the Itoigawa and become a rock hound!
