Kotakigawa Jade Gorge

Named for the crystal clear Kotaki River which runs through it, the Kotakigawa Jade Gorge is a stunningly beautiful jade gorge at the base of Mt. Myojo (1188 m). It is one of Itoigawa’s two jade gorges, alongside the Omigawa Jade Gorge. Discovered in 1938, the massive jade boulders strewn throughout this canyon astounded researchers as they were the first, and to this day the largest, discovery of natural jade in Japan.

Today, the Kotakigawa Jade Gorge is protected as a National Natural Monument and its beauty is enjoyed by thousands of visitors each year.  Enjoy outstanding views of Mt. Myojo’s limestone face and deep gorge below from the Kotakigawa Jade Gorge Observation Deck or take a closer look along the riverbank at the Kotakigawa Jade Gorge Revetment Park.

In addition to walking and hiking trails, visitors can enjoy the Kotakigawa Jade Gorge Fishing Park, Takanami-no-Ike Pond Highland Center, campgrounds and more.
