Keeping on the bridge theme, another popular attraction that is easy to get to from Naruto station with a JR pass is the Iya Kazurabashi Bridge. This is found on right-central Shikoku Island
The Iya Kazurabashi Bridge, or the IKB, is an old-school vine bridge that has been updated and is now steel cable reinforced.But the steel cables don't really matter when you look down and see the gaps between you and the river. I have a size 12 shoe and still really need to watch where I'm walking.Everyone is watching there step on the IKB, I don't think you could have something like this in the US. The liability would be to high.Not everyone showed up to the IKB with the proper foot wear or nature walk clothing on. But it's okay, she had the foresight to remove the shoes to avoid falling through the bridge floor.
