Kiyotsu Gorge, Niigata Prefecture Complete Guide | Explaining the Spectacular Views of Japan’s Top Three Gorges and the Charm of the Gorge Tunnel in Detail
Kiyotsu Gorge (清津峡) located in Tokamachi City, Niigata Prefecture is counted as one of Japan’s three greatest gorges alongside Kurobe Gorge and Osugi Valley, and is one of Japan’s most renowned scenic spots. The V-shaped grand gorge formed over long periods by the Kiyotsu River, a tributary of the Shinano River, was designated as a National Scenic Spot and Natural Monument in 1941 (Showa 16) and became part of the Joshinetsu Kogen National Park in 1949 (Showa 24).
Across the approximately 12.5-kilometer-long gorge, massive columnar jointed rock faces stand vertically on either side of the river, and the changing natural beauty throughout the seasons continues to captivate visitors. In particular, the “Kiyotsu Gorge Tunnel,” renovated at the 2018 Art Triennale, has garnered attention from both domestic and international visitors as a unique experiential space where nature and art converge.
History and Geological Significance of Kiyotsu Gorge
History of Gorge Formation
Kiyotsu Gorge was formed by welded tuff created by volcanic activity approximately 16 million years ago being eroded by the Kiyotsu River. As a result of the river’s flow continuously carving through the bedrock over millions of years, the current magnificent V-shaped gorge was born.
The columnar jointing visible on both banks of the gorge consists of hexagonal columnar cracks formed as lava contracted during cooling. Due to their scale and excellent preservation, they are considered to have very high academic value. The columnar jointed rock faces reaching heights of tens of meters represent the pinnacle of nature’s sculptural beauty.
Designation as a National Scenic Spot and Natural Monument
Kiyotsu Gorge was designated as a National Scenic Spot and Natural Monument on April 23, 1941. This designation signifies recognition not only of the gorge’s scenic beauty but also of its geological and academic value. Among Japan’s three greatest gorges, the development of columnar jointing is particularly notable here, and it holds an important position as educational material for geology.
In 1949 after the war, it was incorporated into the Joshinetsu Kogen National Park, allowing for management that balances natural environmental conservation with utilization as a tourism resource.
Kiyotsu Gorge Tunnel | The Charm of Tunnel of Light
Background of Tunnel Excavation
Previously, Kiyotsu Gorge had a maintained footpath, but it was forced to close following a major rockfall accident in 1988. Subsequently, to allow safe enjoyment of the gorge’s beauty, a 750-meter-long pedestrian-only tunnel opened in 1996.
This tunnel was excavated through the mountainside and features four viewing platforms from which visitors can safely enjoy the gorge’s spectacular scenery. Inside the tunnel, a temperature of approximately 13 degrees is maintained year-round, making it cool in summer and relatively warm in winter.
Transformation into an Art Space through the Art Triennale
During the 2018 “Art Triennale Echigo-Tsumari” (大地の芸術祭), the Kiyotsu Gorge Tunnel was reborn as an art work titled “Tunnel of Light” under the direction of MAD Architects, led by Ma Yansong, a world-renowned architect of Chinese origin.
Multiple art spaces have been created within the tunnel, with the panorama station at the end being particularly impressive. A semi-circular stainless steel arch installed at the tunnel’s tip and a water mirror on the floor reflect the gorge scenery like a mirror, creating a fantastical space as if within a kaleidoscope.
Characteristics of the Four Viewing Platforms
At the First Viewing Platform, the first gorge viewpoint from the tunnel entrance offers close observation of columnar jointed rock faces. Light art effects utilizing natural light are displayed here.
The Second Viewing Platform, called the “Drop Shelter,” is a unique space with a spherical object installed. From here, visitors can view the middle reaches of the gorge and enjoy the changing expressions of the flowing stream with the seasons.
At the Third Viewing Platform, visitors can look down at the deepest part of the gorge, offering the most powerful experience of the V-shaped gorge’s scale.
The Panorama Station (endpoint) is the main attraction, where visitors can enjoy the spectacular “reversed gorge” reflected in the water mirror. The interplay of light, water, and rock face changes with time of day and weather, offering new discoveries even with repeated visits.
The Charm of Kiyotsu Gorge Throughout the Seasons
Spring at Kiyotsu Gorge (April–May)
The Kiyotsu River, swollen with snowmelt, brings dynamic vitality to the spring gorge. The operating season typically begins in late April, and as new greenery begins to sprout, the gorge presents a landscape full of life force.
The contrast between remaining snow and fresh greenery is beautiful, and May in particular offers mild weather ideal for sightseeing. The Golden Week period is expected to be crowded, so early morning or weekday visits are recommended.
Summer at Kiyotsu Gorge (June–August)
The gorge covered in deep green during summer draws visitors seeking coolness. The tunnel’s maintenance of a constant temperature of approximately 13 degrees year-round makes comfortable exploration possible even in peak summer heat, a major attraction.
The Obon period in August is the most crowded time, with entrance queues sometimes occurring on weekends. To avoid crowds, consider visiting early in the morning right at opening or during evening hours. Additionally, food trucks are particularly active during this period, offering dishes made with local ingredients.
Autumn at Kiyotsu Gorge (September–November)
Kiyotsu Gorge displays its most vibrant appearance during the autumn foliage season. From mid-October through early November, the entire gorge is colored in reds and yellows, creating a picture-like landscape with striking contrast against the gray rock walls.
The autumn foliage season is a crowded period comparable to the Golden Week in spring, with many tourists visiting from early morning especially on weekends. October and November feature shortened operating hours of 10:00–16:00, so planned visits are essential.
In the crisp autumn air, the reflected image of autumn leaves in the water mirror at the panorama station becomes an unforgettable scenic memory.
Winter Closure Period
The Kiyotsu Gorge Tunnel closes seasonally from December through late March or early April of the following year due to heavy snow and freezing conditions for safety reasons. During this period the entire facility is closed and entry is not permitted.
Although the area around Kiyotsu Gorge becomes subject to the harsh environment of a heavy snowfall region in winter, spring’s reopening brings the special scenery created by snowmelt streams and fresh greenery.
