Iya Valley

Vine bridges and gorges in Shikoku's deep mountains.

Why Japanese travelers love itIt feels like a hidden mountain world, with vine bridges and quiet hot springs.

The Iya Valley is one of Japan's most remote-feeling places, with steep, forested gorges and small villages on the slopes. The vine bridges over the river are the famous sight. Nearby Oboke Gorge has boat rides between rock walls. Roads are narrow and winding, and buses are few, so a car makes a big difference. Spend a night to slow down.

Best time: Spring to autumn. The Oku-Iya double vine bridges close from December to March.

Getting there

Okayama → Oboke: about 1h30 by Limited Express Nanpu, then local buses. A rental car from Takamatsu, Kochi or Tokushima is easier.

psst — skip this mistake: Driving fast on the valley roads. They are narrow, often one lane, with blind curves.
