Itoigawa

Itoigawa (糸魚川) is a city at the far southwestern corner of Niigata Prefecture, situated at the northern terminus of the Itoigawa-Shizuoka Tectonic Line—a major fault that geologically separates northeastern and southwestern Japan. This unique geology gives the area extraordinary mineral diversity, including Japan's finest jade, and has earned it designation as a UNESCO Global Geopark. The coastline offers dramatic views of the Sea of Japan, while the nearby mountains provide hiking and skiing. Itoigawa is best visited in spring, autumn, and summer; winters bring heavy snow along the coast.
