Iya and Oboke: a vine bridge, a waterfall and a gorge boat ride

Cross Iya Kazurabashi

Winter 2027 closure: Crossing and evening illumination will be suspended for rebuilding from 12 January until around the end of February 2027. Snow may delay the work. Check Tokushima’s official closure update before planning a winter visit.

The 45-metre bridge hangs 14 metres above the Iya River. Take in its woven structure and the water below as you cross; the gaps between the footholds and the movement of the suspended bridge are part of the experience.

If heights or uncertain footing are uncomfortable, enjoy its river setting from the bank instead.

Stories about its origins include defeated Heike warriors and the monk Kobo Daishi; they are local traditions rather than a single established account.

Look closely at the weave as well as the drop. Thick vines wrap around the sides, while spaced wooden footholds leave the river visible beneath your feet. The bridge is not a relic left untouched: its three-year rebuilding cycle keeps local skills in use. The tourism association describes craftspeople working with natural materials, including shirakuchi-kazura vines, using techniques handed down through generations. Seeing those bindings gives the crossing a second story, beyond the first flutter of nerves.

Admission is ¥550 for junior-high-school age and above, ¥350 for elementary-school children, and free for preschool children.

Entry hours are 8 a.m.–6 p.m. in April–June, 7:30 a.m.–6:30 p.m. in July–August, and 8 a.m.–5 p.m. in September–March.

The bridge normally opens in rain, but a heavy-rain warning or other severe conditions can cause a temporary closure. Wear shoes that give secure footing and follow the instructions at the crossing.

The evening illumination runs from 7–9:30 p.m.; crossing is not permitted during the illumination.

The closure also brings a different way to see the bridge. Miyoshi’s tourism association has announced guided rebuilding visits on 16, 23 and 30 January and 6 February 2027, with advance booking and limited places. These are visits to learn about the vines and watch the work, not opportunities to cross the closed bridge. The tour details published by Mannaka include sessions, fees and the tourism association’s reservation contact; snow, ice or severe weather can cancel a visit.

Pause at Biwa Falls

After crossing, turn left for the short walk to Biwa Falls, about 50 metres away.

The cascade drops through a green, rocky cleft, giving you a different view of the valley’s water after the open river crossing. Allow a quiet pause here before returning toward your bus stop or car.

A riverside path and steps lie farther along, but the tourism office warns against entering the riverbank when the river is high. Keep to the permitted paths and any barriers in place.

See Oboke from the water

Oboke’s sightseeing boats travel through the Yoshino River gorge between sharply angled rock walls. Watch the changing shapes of the layered stone as the boat rounds the bends.

The rock walls have a story far older than the boats. Japan’s cultural-heritage register explains that rocks here were pushed deep underground and recrystallised under pressure, then folded into a broad arch-like structure. From the river, notice the angles and lines in the exposed stone as well as its pale colour. It is a chance to look at the gorge as a shaped landscape, not simply a backdrop for the ride.

The usual trip lasts about 30 minutes and returns to the same landing, so it works as a separate stop rather than onward transport.

Buy tickets at the first-floor front desk of Restaurant Obokekyo Mannaka, then follow the indoor route toward the landing. Reservations are not required, and solo visitors can join.

The operator lists departures as needed between 9 a.m. and 5 p.m., with the last departure at 4:30 p.m.

The current fare is ¥1,800 for adults and ¥900 for children aged three through elementary school. Everyone must wear the life jacket supplied at the landing. Strong wind, high water or storms can cancel departures; low water can shorten the route.

Arrange the journey around Oboke Station

JR Oboke Station is a useful gateway for this outing. For the vine bridge, the city’s tourism guide directs visitors to Shikoku Kotsu buses bound for Kazurabashi Yumebutai or Hotel Iya Onsen, alighting at Kazurabashi Yumebutai and walking about five minutes.

Check the current bus timetable for the particular stops and return journey you need: services take different routes through the valley.

Oboke Gorge and the vine bridge are separate stops, not adjacent attractions connected by a short stroll. A car or a taxi arranged ahead gives more flexibility between them.

A satisfying first visit can focus on the bridge, nearby waterfall and one boat ride, with time for lunch between the two areas. The deeper valley’s double vine bridges belong to a longer journey; they are not the same attraction as Iya Kazurabashi.

Official planning guides

Use Miyoshi’s Iya Kazurabashi guide for crossing details and local access, and the Obokekyo Mannaka boat guide for fares, operating conditions and its boat video. If the video does not play, their photographs and written guides offer a useful alternative.
