Itoigawa Geopark - 500 Million Years of Earth's History and the Oldest Jade Culture in the World 
Itoigawa Geopark
 The Itoigawa Geopark is situated in the westernmost end of Niigata Prefecture, Japan, near Toyama and Nagano. The area is crisscrossed by rock strata from different ages ranging from jade-bearing strata formed 500 million years ago to metamorphic rock strata from 3000 years ago. With elevations ranging from 0 to 2,766 meters above the sea level, the rugged terrain is home to a wide variety of plants and animals. The Itoigawa Geopark boasts the world's oldest jade culture as well as a salt trail that runs along a fault line. Signs of Earth's early history as well as the bounty of Mother Nature can be seen everywhere throughout the geopark and are also closely bound up with the lives of the local people. Thanks to the area's unique geology, seafood from the Sea of Japan, ingredients harvested from the land as well as famous local wines have given rise to a delicious and distinctive style of cuisine.

What attractions does Itoigawa Geopark offer? 
What attractions does Itoigawa Geopark offer?
 The "Itoigawa-Shizuoka Tectonic Line" that bisects Japan passes through the region, giving the Itoigawa Geopark a unique geology and topography. We have organized these geological and topographic features into 24 geosites and sights to provide an easy-to-understand yet comprehensive introduction to these precious natural phenomena.
There are also two national parks (Chubu-Sangaku and Joshin'etsu Kogen) and three prefectural natural parks (Oyashirazu-Koshirazu, Kubiki and Hakuba Sanroku), adding national and prefectural cultural heritage sites to the fun of mountain climbing and hot springs. A major attraction of the Itoigawa Geopark is the varied geology and experiences available that offers something for everyone. 
The Itoigawa-Shizuoka Tectonic Line that passes through the area has led to distinctive differences in local cultures, habits, customs and language. The area is therefore a meeting point between western and eastern Japan mixed in with local characteristics filled with surprises.
 
What is a geopark?
the administration of the geopark
 The geopark is a natural park where people can enjoy the beauty of nature and learn how closely mankind is related to the land at the same time. A geopark is not just a geological heritage site. In the beginning, people are drawn by the magnificent views, rare fauna and flora. The senses are then gradually seduced by the culture, history as well as cuisine and hot springs. The geopark can therefore be considered a natural theme park for learning through play.
 
What are Global Geoparks?
The Global Geoparks Network (GGN) is a program supported by the United Nations Educational, Scientific and Cultural Organization (UNESCO). The mission of GGN is to protect rare and important geological sites, flora, fauna, cultural and industrial heritage sites throughout the world. GGN also seeks to revitalize local economies and cultural activities through the promotion of tourism. 
The Location of the geoparks in Japan
There are currently 77 geoparks in 25 member states around the world. Three are located within Japan (Itoigawa, Toya Caldera and Usu Volcano, and Unzen Volcanic Area).

Dividing line between northeastern and southwestern Japan
 Dividing line between northeastern and southwestern Japan
The Itoigawa-Shizuoka Tectonic Line that passes through Itoigawa divided northeastern Japan from southwestern Japan. The divide is not only reflected in geological differences but also in the topographic, biological and cultural diversity. 
Large differences in elevation 
Large differences in elevation

The large difference in elevation between the Sea of Japan and Mt. Korengesan (2,766 m), the highest point in Niigata, has produced a very diverse ecosystem. The influence on human civilization is also very extensive. 
Wide geological range

Itoigawa contains all of the rock strata from the Paleozoic to the Cenozoic Eras. The oldest known jade-bearing strata in the world from 500 million years ago is also found here.

The land in Itoigawa is composed of volcanic, metamorphic and sedimentary rocks. These have a strong influence on the type and distribution of flora and fauna. 
 Interwoven history of mankind and nature
Interwoven history of mankind and nature
Prehistoric jade and jadeite as well as modern gold, limestone, pottery clay and brick clay have led to human history being intertwined with nature. The oldest jade culture in the world was based on jade produced in Itoigawa.

The Fossa Magna has given rise to delicious seafood such as the Japanese Spider Crab, Sucker Fish and Sweet Shrimp as well as many other local delicacies. The high quality of water, rice and grains has also given rise to five distinctive wineries.
