Iya Valley

Vine bridges, deep gorges and mountain hot springs

The Iya Valley is a deep river gorge in Miyoshi City in western Tokushima Prefecture on the island of Shikoku. Its steep slopes have small hamlets, terraced fields and the Iya Kazurabashi, a 45 m vine suspension bridge. Further in are the Oku-Iya twin bridges and the hillside houses of Ochiai village. Visitors can also take a boat through the Oboke Gorge or soak in an onsen above the river. Buses are infrequent and roads are narrow, so a hire car or a taxi helps. Staying a night lets you see the valley after the day trippers leave.

Why travel to Iya Valley?

The Iya Valley is known for its vine bridges. The Iya Kazurabashi crosses the Iya River on thick vines and is 45 m long and about 14 m above the water. You walk across wooden planks laid between the vines with the river visible through the gaps. Farther up the valley the Oku-Iya double vine bridges, known as the husband and wife bridges, are in a quieter forest setting. The valley also has the village of Ochiai, where old farmhouses are on a steep mountainside and one thatched house is open to the public. On a cliff above the road a small statue of a boy relieving himself looks over a long drop into the gorge. Boats run through Oboke Gorge near the station. Hotel Iya Onsen has a cable car that takes guests down to an onsen bath beside the river. The Iya Valley suits one or two days. It works as a stop between Takamatsu, Kochi and Okayama and is a break from Shikoku's coastal cities. Public transport is limited, so planning matters more here than at most places in Japan.

Knowledge before you go

The Kazurabashi bridge charges JP¥550 (£2.61) for adults and has seasonal hours.
Buses are infrequent, so check the return timetable before heading out to the bridges.
Oku-Iya's double vine bridges are an hour by car from the main one and need a short walk.
The vines are replaced every three years, so the bridge you walk across is always fairly new.

How to travel to Iya Valley

Most visitors come by train to Oboke or Awa-Ikeda on the JR Dosan line and continue by bus, taxi or hire car. The Nanpu limited express runs hourly from Okayama to Awa-Ikeda in about 90 minutes and carries on to Oboke and Kochi. From Takamatsu the trip takes about 1.5 hours with a change. Kochi is about an hour away. Takamatsu Airport (TAK) is about 43 km away and Tokushima Awaodori Airport (TKS) is about 87 km. A hire car from either airport is simplest. By car, the Takamatsu Expressway reaches Ikeda in roughly an hour and the bridge is about another 45 minutes beyond. From Osaka the drive takes roughly 3 hours or more depending on traffic. Roads in the valley are narrow and winding.

Access summary

From Tokushima Airport: Bus/train via Awa-Ikeda–Oboke, typically 3–4 hours.
From Osaka: Limited express train plus local bus, usually about 5–6 hours.
From Takamatsu: Airport or city to Oboke by bus/train, roughly 3–3.5 hours.

Where to stay in Iya Valley

Accommodation in the Iya Valley is small and spread out, with a few onsen hotels, family-run ryokan and minshuku plus renovated thatched farmhouses that rent rooms. The most atmospheric options are in the villages and beside the river. Many include dinner. The larger towns at the entrance to the valley, Awa-Ikeda and Oboke, have business hotels and inns and are handier for the trains. Staying there gives you a base for day trips but adds driving time each day. Rooms are limited, so book well ahead, especially in autumn and at holiday weekends. If the valley is full, Takamatsu and Kochi have far more rooms, though each is a long drive. Staying a night in the valley means you can reach the bridges early before the day trippers arrive.

How to get around Iya Valley

A hire car is the easiest way to see the Iya Valley because the sights are spread along narrow mountain roads.

By car and foot:
Parts of the road are single lane with passing places, so drive slowly and expect oncoming vehicles around blind curves. Fuel stops are few, so fill up in Miyoshi or Awa-Ikeda before you head in. Villages like Ochiai are best seen on foot once you arrive.

Buses:
Buses from JR Oboke Station and Awa-Ikeda Bus Terminal serve the main stops but run infrequently, so check the timetable before you go. From Oboke Station a bus to the vine bridge takes about 20 minutes. From Awa-Ikeda buses take about 50 to 70 minutes.

Taxis and tours:
Taxis operate from the main stations and can be booked ahead for the trip up the valley, which is worth doing if you want a flexible day. The Oku-Iya vine bridges are farther in and need a car or a private tour. Guided tours from nearby cities are another option.

Food in Iya Valley

Food in the Iya Valley is simple and tied to the mountains. Iya soba is a thick, rustic buckwheat noodle served hot or cold in local restaurants. Dekomawashi is skewered tofu, konnyaku and potato grilled over charcoal and brushed with sweet miso. River fish like ayu are grilled with salt while mountain vegetables appear in season.

Restaurants are few and tend to close early, so plan lunch around the sights. A few shops near the vine bridge sell snacks and soft drinks. Convenience stores are rare up the valley, so buy drinks and supplies in Awa-Ikeda or Miyoshi first.

Most ryokan and minshuku serve set dinners based on local ingredients, which is easier than hunting for a place at night. Vegetarians should ask in advance since broth and fish are common.

Safety information overview

General safety

The Iya Valley is very safe from crime, so the hazards come from the terrain. Mountain roads are narrow and winding and landslides after heavy rain or ice in winter can close them. The vine bridges sway and have gaps between the planks.

Health & Medical

Medical care is limited in the valley itself. Clinics and a hospital are in Miyoshi, so serious treatment can be an hour or more away on winding roads. Bring any medicines you need and carry water on walks, since summers are hot and humid.

Accessibility

The valley isn't suited to wheelchairs or limited mobility. The vine bridges are swaying planks with gaps, villages like Ochiai sit on steep slopes and many paths have steps. Buses are few, so a car or taxi is practically essential.

Tap water

Tap water in the Iya Valley is safe to drink, as in the rest of Japan. Shops and vending machines are sparse up the valley, so carry bottled water or tea from Awa-Ikeda or Miyoshi. Don't drink untreated river water.
