Kiyotsu Gorge Tunnel (Tunnel of Light)
SaveA 750-meter tunnel dug through one of Japan's three great gorges, ending in an observation space.
At the far end a shallow film of water on the floor turns the gorge upside down.
MoreWhat kind of place
Kiyotsu is counted among Japan's three great gorges, alongside Kurobe in Toyama and Osugidani in Mie. Its columnar rock walls were named a national Place of Scenic Beauty and Natural Monument in 1941.
The riverside hiking trail closed after a rockfall in 1988, so the village of Nakasato bored this walkway through the mountain instead, at a cost of about 2 billion yen, and opened it in October 1996.
After visitor numbers slipped to roughly 50,000 a year, Ma Yansong of MAD Architects remade the tunnel as an artwork in 2018.
The restroom at the second lookout is part of the art now, so there is sometimes a wait while people photograph it.

- There are no coin lockers or any other place to leave your bags.source
- There are no trash cans, so you carry your trash out with you.source
- Because this is a national park, smoking is banned everywhere from the parking lots through the tunnel.source
- Pets can come into the tunnel under rules that include carrying out their waste, keeping leashes to one meter (about 3 feet) or shorter, and not putting animals in the loaner wheelchairs or strollers.source
- The Panorama Station at the far end holds a layer of water that is 0.5 to 2 centimeters deep at the edges, roughly a quarter to three quarters of an inch, and you can walk on it, though it is very easy to get wet.source
- Spare shoes, socks, and a towel are recommended.source
- At the Panorama Station, several groups take photos at the same time, with no queue and no set direction of travel.source
- The tunnel has three lookout points plus the Panorama Station at the end.source
- The Panorama Station is an art space where a shallow pool of water reflects the gorge upside down.source
- One stretch of the tunnel has displays about the surrounding area, its nature, and its culture.source
- The cliffs are bundles of columnar rock rather than one solid mass, so the stone is hard but brittle and crumbles easily.source
- Fresh greenery and clear water are at their best from early May through late June, and patches of snow linger into around June.source
- From December through March, snow can leave no room for the food trucks to set up, so they may not be there.source
With kidsThe part that matters
You walk the half-mile tunnel (750 meters) and come back out the same way, about a mile in all: 30 to 40 minutes officially, and 50 to 60 for a family who walked it with a grade-schooler.
At the far end the floor holds a shallow pool, less than an inch deep at the edges, and the gorge shows up in it upside down.
The water soaks shoes fast, so pack spare socks and a second pair of shoes for whoever wades in and nobody walks back out wet.
Two strollers, three wheelchairs, and a push cart wait inside the tunnel, free to anyone and left where you found them, but none of them can be reserved, so take one while it is free rather than counting on it later.
The public restroom by Parking Lot 1 has four stalls on the women's side against the single one in the entrance building, so stopping there on the way in saves you the wait.

- With a fourth-grader: 50-60 min round trip, no steps for a stroller, but not onto the water at the end. Wear sandals.source
- Two meters of snow most years: ice underfoot, meltwater wetting shoes. Snow boots, winter tires, only lot 1 open.source
- Four free parking lots, about 155 spaces. Lot 1 is a 10-minute walk in; at 12:45 on 17 May it had three spaces left.source
- Late October in the color: the tunnel is dark, wet and uneven, and groups queue to photograph the Panorama Station.source
By age0-1 / 2-3 / 4-6
- Ages 0-1The tunnel is a single 750-meter path, 30 to 40 minutes there and back. Two strollers sit inside it, free to take and use, so when your arms give out you can set the baby down and keep going. There are three lookouts, and at the Panorama Station at the far end the rock face of the gorge is reflected upside down in the water on the floor, a view that spreads across the ground and is there to look at from your arms.The Panorama Station holds water on its floor; at the edge it is 0.5 to 2 cm deep and you can walk in it, but you get wet very easily, so bring a change of shoes and socks and a towel. The two strollers, three wheelchairs and one walker inside the tunnel cannot be reserved, and you return them where you found them. The public restroom in front of Parking Lot 1 has a multipurpose stall; the restroom in the entrance building has only one women's stall and one multipurpose stall, so the site itself points you to the parking lot one. There are no trash bins, so used diapers go home with you. It is a 3-5 minute walk from Parking Lot 1 to the tunnel entrance and 7-10 minutes from Parking Lot 2. Preschool children enter free, and they do not need an advance ticket even on the reservation-only days.
- Ages 2-3At the Panorama Station at the far end the water is 0.5 to 2 cm deep at the edge, shallow enough for a child to walk in on their own feet. Getting there is one straight 750-meter path, with three lookouts to stop at along the way. The restroom at the second lookout doubles as an artwork, so you can go and look inside it. The footbath on the second floor of the entrance building is free and open from April to November.The water mirror soaks you easily, so pack a change of shoes and socks and a towel. For when small legs give out, the tunnel has two strollers and one walker inside, free to take and use, though they cannot be reserved. The official round trip is 30-40 minutes; a family with a fourth-grader took 50-60. There is no time limit once you are inside, so you can go at a toddler's pace. Preschool children enter free. There are no trash bins, so whatever you bring in comes back out with you.
- Ages 4-6The cliff of the gorge is a bundle of column-shaped rocks, not one solid face. Three lookouts show that stack of columns from different angles, and at the Panorama Station at the far end you can check the same rock face again, reflected upside down in the water on the floor. The restroom at the second lookout doubles as an artwork. Inside the tunnel there is also a corner introducing the nature and culture of this area.The water mirror soaks you easily, so pack a change of shoes and socks and a towel. The walking is a 30-40 minute round trip through the tunnel (50-60 for a family with a fourth-grader), plus 3-5 minutes in from Parking Lot 1. The second lookout's restroom can have a queue, since people go in to photograph it. Preschool children are free; elementary and junior high students pay 500 yen in high season (April 21 to November 20) and 400 yen off season. High season includes reservation-only days when tickets are not sold on site: in 2026 these are May 2-6, July 18-20, August 1-4, August 8-16, September 19-23, October 10-12, and October 24 to November 3. There are no trash bins, so everything goes home with you.

The Kiyotsu gorge ranks with Kurobe and Osugidani as one of Japan's three great gorges. Its cliffs are bundles of columnar joints, hard rock but liable to crumble. A rockfall in 1988 closed the riverside path, and this 750-meter tunnel was opened in 1996 to replace it. In 2018 MAD Architects rebuilt it as Tunnel of Light. Past three viewpoints, the floor at the end holds a shallow film of water that flips the gorge upside down. There and back takes 30 to 40 minutes.
| Stroller friendly | Yes | Two strollers, three wheelchairs and one walking trolley sit inside the tunnel, free to use — but they cannot be reserved, so on a busy day they may already be out. Put them back where you found them. Getting there is a walk of its own: 3-5 minutes from parking lot 1, 7-10 from parking lot 2, and about 30 minutes on foot from the Kiyotsukyo-iriguchi bus stop, with no taxis allowed on that stretch. | Web-checked | checked Aug ’26 | nakasato-kiyotsu.com |

Four parking lots hold about 155 cars in all, with two priority spaces at parking lot 1; they close 18:00-7:00.

Kitchen cars sell food on the entrance terrace, though in winter snow can leave no room for them. | Web-checked | checked Aug ’26 | nakasato-kiyotsu.com |
