Kazurabashi at Oku-Iya — Double Vine Bridges and Cable Car

Deeper in the Iya Valley, 45 minutes beyond the main tourist bridge, lie the Oku-Iya Double Kazurabashi (奥祖谷二重かずら橋) — two smaller vine bridges nicknamed 'Husband' and 'Wife' suspended side-by-side over a narrow gorge. The bridges are less reconstructed and more precarious-feeling than the main Iya bridge, with the original 'wild' aesthetic intact. Next to them stands a yaen (野猿) — a human-powered cable car where riders pull themselves across the gorge via overhead rope.

The remote location (population near zero) and lack of crowds make Oku-Iya feel genuinely adventurous compared to the main bridge's tour bus atmosphere.
