South of Kyoto, on the Kizu River, there’s a wooden footbridge that looks a hundred years out of date. It’s one of the longest of its kind in Japan, built to be carried off every time the river floods, then hauled back once the water drops. That’s the whole point.

The first thing you’ll notice is that there are no railings. A bare plank walkway, 356 meters of it, laid low over a wide, shallow river, with nothing to hold on to. It carries no signs, no lights, nothing that would place it in the present century. It looks less like a bridge than a film set nobody bothered to take down, and a few weeks a year that’s pretty much what it is. It has the look of the Edo period for a practical reason: it is built to fall apart. When the Kizu rises past a certain point, the deck lifts off its piers and floats off downstream. That isn’t the bridge failing. That’s the bridge working. Locals call it Nagarebashi, the flowing bridge, and the nickname has stuck better than its official name ever did.
When the deck floats off, it doesn’t wash away. You’d think loose planks in a flooded river would be gone for good, but these don’t go anywhere. The deck is built in separate sections, and each one is cabled to the piers. So when the water lifts a section free, it just rides there in the current like a boat on a mooring, pulling at its line but going nowhere.
