Kiyotsu Gorge Tunnel "Tunnel of Light": A Spectacle of Gorge Beauty and Art in a Water Mirror

Kiyotsu Gorge in Tokamachi City, Niigata Prefecture, is one of Japan's three great gorges, alongside the Kurobe Gorge in Toyama and Osugidani in Mie. What lets you enjoy the gorge safely is the roughly 750-meter Kiyotsu Gorge Tunnel. In 2018, in conjunction with the international arts festival, the Echigo-Tsumari Art Triennale, the entire tunnel was reborn as an artwork called the "Tunnel of Light" by MAD Architects, led by the Chinese architect Ma Yansong. The gorge beauty mirrored in the water at the far end is a one-of-a-kind spectacle that has drawn attention on social media.

Highlights

A Tunnel Reborn as Art

The Kiyotsu Gorge Tunnel was originally a pedestrian tunnel dug to view the gorge safely. In the 2018 renovation, based on the concept of MAD Architects, art spaces using light, color, water, and mirrors were placed throughout the tunnel. The dreamlike staging that appears as you advance is an experience found nowhere else, fusing natural gorge beauty with contemporary art. Because it is pedestrian-only, another great appeal is being able to stroll safely while viewing the gorge's cliffs up close.

The Highlight: The Panorama Station

The "Panorama Station" at the far end of the tunnel is this work's highlight. Its walls are covered with stainless steel panels, and a thin layer of water is spread across the floor. This water mirrors the gorge and sky, creating a dreamlike scene in which the gorge seems to float on the water's surface. It is a prime photo spot where visitors stand by the water to take pictures. The magnificent gorge beauty of the columnar joints of rock, together with the symmetrical beauty woven by the mirror image, is a truly breathtaking sight.

Enjoying the Seasons

Kiyotsu Gorge changes its face throughout the four seasons. Early summer, when fresh greenery colors the gorge, is a refreshing season when the rock faces and the green of the trees reflect in the water mirror. In autumn the entire gorge turns to autumn foliage, and the reds and yellows reflected in the Panorama Station's water surface make it the most brilliant time of year. In winter, amid snowy scenery, you can savor the tunnel's art wrapped in stillness. If your aim is photography, target a clear day in the fresh-green or foliage season when the water mirror reflects most beautifully. Note, however, that the popular seasons are extremely crowded.

Access and Basic Information

To reach Kiyotsu Gorge, take a bus from Echigo-Yuzawa Station, served by the Joetsu Shinkansen and the Hokuhoku Line among others, to the "Kiyotsukyo-iriguchi" bus stop, from which it is a walk to the tunnel entrance. By car, interchanges such as Shiozawa-Ishiuchi on the Kan-etsu Expressway are convenient. From the tunnel entrance to the Panorama Station at the far end is about 750 meters each way, and the round trip takes roughly 40 minutes to 1 hour depending on your walking pace. There is an admission fee, and during busy periods such as Golden Week, Obon, and the arts festival, advance reservations may be required. Always check the official information before visiting.

Practical Travel Notes

• Reserve in advance in busy periods: during Golden Week, Obon, long weekends, and event periods, advance reservations may be required for entry. Check the latest reservation requirements and fees on the official website before setting out.
• Tips for photographing the water mirror: the Panorama Station's water surface reflects the gorge most cleanly when there is no wind. Many people stand at the water's edge barefoot or in sandals, but as your feet may get wet, spare socks and a towel are reassuring.
• Wear comfortable shoes: there is the walkway to the tunnel and a round trip of about 1.5 kilometers on foot. Comfortable shoes are recommended.
• The tunnel is cool inside: even when it is hot outside, the tunnel feels cool. A light layer is comfortable even in summer.
• Avoid peak times: if you want to photograph at leisure, visiting early right after opening or at off-peak times is recommended.

A Word of Advice

The appeal of the Kiyotsu Gorge Tunnel lies in a one-of-a-kind experience uniting the magnificent natural beauty of one of Japan's three great gorges with contemporary art by MAD Architects. The Panorama Station's water mirror in particular is a spectacle that shows its true worth when the conditions of weather, light, and wind align. Do not forget to reserve in advance during busy periods, and if possible choose a clear day with gentle wind so you can fully savor the dreamlike scene of the gorge floating on the water.
