Kiyotsu Gorge is a stunning canyon formed by the Kiyotsu River, spanning the areas of Tokamachi and Yuzawa in Niigata Prefecture. Recognized as one of Japan's three major canyons, it is designated as a national scenic spot and a natural monument. The most iconic feature is the approximately 750-meter-long "Kiyotsu Gorge Tunnel." This tunnel was redesigned as an art installation by the Chinese architectural group MAD Architects (Ma Yansong) during the 2018 "Echigo-Tsumari Art Triennale." It offers a truly unique space where the raw beauty of nature and modern architectural elegance coexist seamlessly.
The formation of Kiyotsu Gorge is a testament to the grand history of the Earth. The geological layers were shaped by volcanic activity approximately 15 million years ago, and about 7 million years ago, the intrusion of magma created the unique rock formations known as "columnar jointing." Over time, the erosion by the Kiyotsu River carved the deep, beautiful canyon seen today. Historically, the region has been cherished for its hot springs, with Koide Onsen having opened as early as 1801. The name "Kiyotsu Gorge" was officially established in 1934, recognizing its immense academic and scenic value.

The interior of the Kiyotsu Gorge Tunnel is the most captivating part of the experience. Near the end of the tunnel, you will find the "Water Mirror" area, where the scenery reflects off a shallow pool of water. This creates an illusion of infinite space, enhanced by the surrounding rock walls and light effects. The tunnel itself is a work of art, designed with the elemental themes of "wood, earth, metal, fire, and water." The changing expressions of the canyon through the seasons provide a constantly evolving spectacle that fascinates every visitor.
Kiyotsu Gorge presents a completely different face depending on when you visit. You can enjoy the fresh greenery in early May, the vibrant autumn colors from late October to early November, or the serene, snow-covered landscapes from late December to early April. The autumn foliage and winter snowscapes are particularly popular and draw many photographers. Please note that during the winter season, access may be restricted or the site may close due to heavy snowfall, so checking the local conditions in advance is highly recommended.

Walking through the tunnel to witness the fusion of nature and art is an experience unique to Kiyotsu Gorge. At the entrance facility, you can relax at the footbath (note: the footbath is closed during winter) or visit the cafe and souvenir shop. It is a perfect place to spend a luxurious moment connecting with art and nature. For those seeking a deeper understanding, professional guided services by local guides are also available for a fee.
The area surrounding Kiyotsu Gorge is rich in hot spring resorts and natural beauty. The nearby "Kiyotsu Kyo Koide Onsen" is an excellent place to soak and relax after your visit. If you head toward the Yuzawa area, you will find various activities such as ropeway rides and trekking courses. While driving is the most convenient way to access the site, you can also enjoy the scenic views via public transportation and local buses.

Since the area around the "Water Mirror" can be damp, we recommend bringing a small towel. Because temperatures can fluctuate significantly depending on the season, please dress appropriately. Regarding photography, the use of drones is strictly prohibited to protect the environment unless a special permit is obtained. For entrance fees, please be aware that some days require advanced reservations via the official website.
