Oku-Iya Double Vine Bridge

Hidden deep in the forested walls of Iya Valley, the Oku‑Iya Double Vine Bridge is actually two kazurabashi [蔓橋, vine bridges] built roughly 800 years ago by the Heike clan. Legend says they needed these to reach their horseback training grounds on Mt. Tsurugi, and they were designed to be severed in times of danger to slow pursuers. The longer of the two, the Otokobashi (Men’s bridge), stretches about 42 m long and 2 m wide, hovering 12 m above the river. A few meters away lies the shorter Onnabashi (Women’s bridge), around 22 m long, 1.2 m wide, and 4 m high, together often called the “husband and wife bridges” or Meoto‑bashi [夫婦橋].

You’ll find the bridges set over a plunging gorge with a crystal‑clear stream below, surrounded by untouched forest. There’s no commercial development, just pure nature. The paths lead you quietly through mossy rocks and ferned slopes. Many talk about how it feels like stumbling upon something sacred and ancient, far from typical tourist sites.

The magic is in crossing each bridge. The wooden slats creak beneath your feet, the hand‑woven vines feel alive in your hands, and looking down at the river adds a flutter of excitement. Crossing it once is thrilling, crossing twice gives time to absorb the serenity and craft.

Around the site are some flat river stones perfect for picnicking or just soaking in the view. On-site toilets and a small parking lot (about 30 spaces) make it comfortable for visitors, though you won’t find cafés or shops nearby, just wild nature and the sound of water rushing below.

Fall is a standout season here: maples and beech turn fiery red and gold earlier in Oku‑Iya than other parts of the region, and the rich color palette against the bridge and river is breathtaking. But spring greens and summer forest shade feel equally enchanting, especially when the water runs cold and clear.
