Oku-Iya Niju Kazurabashi Bridge
Beyond Oboke Gorge, called one of the leading unexplored regions of Japan, you will find Oku-Iya Niju Kazurabashi Bridge. On a plateau with an elevation of about 1000 meters, there is an ancient double suspension bridge by this name, made of creeping plants such as ivy-leafed ferns.
I visited both the Iya Kazurabashi and Oku-Iya Niju Kazurabashi bridges. I think the latter is more beautiful. You can even go down to the river under the bridge and have a picnic sitting on the rocks by the water—it's really relaxing.
