Oku Iya Vine Bridges Travel Guide

The Yaen Monkey Cart and Other Highlights

One of the best surprises at the Oku-Iya bridges is the Yaen wild-monkey cable cart — and it is completely free to use. This small wooden cart holds up to three people and slides across the river on suspended wires. Riders pull themselves hand-over-hand across the span, which is slower and more comical than it sounds, especially for children.

A waterfall tumbles down just below the husband's bridge, adding a satisfying backdrop to the visit. The Iya River between the two spans has large flat stones ideal for a riverside picnic or wading on warm days. Tables near the adjacent campground give families another comfortable option for a relaxed lunch stop.

A nature trail heads up the valley from the wife's bridge for about a kilometer along the riverbank. Hikers wanting more can pick up the trailhead for Mt Maruishi near the waterfall below the husband's bridge. Allow about three hours up and two hours down for Mt Maruishi, or plan a full day if aiming for the higher ridge connecting to Mt Tsurugi.

Tickets, Hours, and Seasonal Closures

Entry is straightforward: adults pay ¥550 and children pay ¥350 at the roadside entrance booth. There is no advance booking system — admission is pay-on-the-day and the site never sells out. The fee covers unlimited bridge crossings, and the Yaen monkey cart is included at no extra charge.

Opening hours shift by season: the bridges open from 9:00 to 17:00 during April through June and again from September through November. During the summer months of July and August, hours extend to 8:00–18:00. The bridges close entirely from December through March, so a winter detour will find the site locked.

Autumn (October–November) delivers the valley's most dramatic scenery, with deep reds and golds framing the vine spans. Summer draws the largest groups, especially on weekends and public holidays, so weekday mornings are calmer. Spring (April–May) offers fresh green canopy and the fewest visitors — a strong choice for travelers who prefer a quieter crossing.

Getting to the Oku-Iya Double Vine Bridges

A rental car is by far the most practical way to reach the Oku-Iya vine bridges. The site sits on Route 439 with free parking on both sides of the entrance booth. From Oboke Station, allow 75–80 minutes of driving, and from the Nishi-Iya Kazurabashi area, add another 50–60 minutes beyond that.

The road narrows to a single lane for most of the Oku-Iya stretch, with passing places cut into the hillside. Take your time, especially on the curves above the river ravines, and expect occasional oncoming vehicles. Our full guide on how to get to the Iya Valley covers the complete route from Osaka or Takamatsu by train and rental car.

Public buses reach the area but only partway. The main Shikoku Kotsu buses from Ikeda stop at Kubo in Oku-Iya, roughly 25 minutes by car from the bridges. The Local Miyoshi Municipal Bus goes further, reaching Nagoro (Scarecrow Village) just 4km from the bridges, but runs on weekends and public holidays only (April–November).

From Nagoro, the walk to the bridges takes 60–70 minutes on a mountain road, a little longer on the uphill return. Our nagoro scarecrow village covers the village itself, which makes a compelling add-on before or after the walk. Attempting to hitch a ride from Nagoro is worth trying, though traffic this deep into the valley is sparse.

Where to Stay and What to Do Nearby

The Oku-Iya Niju Kazurabashi Campground sits right beside the wife's bridge, making it the most atmospheric base for an overnight. Basic facilities including toilets are available on-site, and the sound of the river at night is a genuine highlight. The campground follows the same seasonal window as the bridges, so confirm availability before planning an overnight stay.

For more comfort, the Iya Valley has ryokan and small onsen hotels further down the valley toward Nishi-Iya. These properties typically offer hot-spring baths and dinner service, which feels well-earned after a long day of mountain driving. Our Iya Valley onsen and where to stay guide covers the full range from riverside camping to traditional guesthouses.

The Maruishi Parkland restaurant and souvenir shop is the only dining option within walking distance of the bridges, so arrive with snacks or a packed lunch. Nagoro, roughly 10 minutes by car, is home to the famous Scarecrow Village and makes a low-effort afternoon add-on. On the drive back toward Oboke, the Oboke Gorge boat tours round out a full day in the valley with a scenic river perspective.
