Tsuujunkyo bridge is the most famous bridge in the Kumamoto region, if not Kyushu all together. This bridge was designed specifically to carry water high accross the deap ravine. In the distance is a waterfall, but the people in the village over the hill had no way to get water accept to climb up the mountain every day, get some water and climb back down. The bridge was developed in the late seventeen hundress and shows the fine craftsmenship of the Japanese. Using a stone bridge to cary water and act as a means of transport? This is engineering ingenuity and pretty darn cool if you ask me!
Sayaka peaks over the ledge
You can see Sayaka peaking over at me as I took this picture. Just to the lower right of her you can see the funel spout with water trickling out of it. Right now there is a plug which is blocking the water, but when you pull that plug out both sides of the bridge spout water. The pressure of the water which shoots out of that hole on the bridge is the equivilant to a fire hose which puts out a fire. Pretty amazing, and I would have liked to see it, but we came in the cool evening of an uncrowded off day; which so happened to be equally as beautiful and relaxing.
Inside the bridge
This is the water transport blocks contructed within the bridge. When they are put in rows the square hole acts as a pipe to transfer the water across. There are four rows of these pipes which span the entire length of the bridge. In case of high pressure incidents, such as heavy rain fall or freezing, which threaten to burst the bridge a gate is stopped at either end and the plugs are removed to drain all the water, which then proceeds to shoot out of the sides of the bridge making a neat spectacle.
Me sitting on the bridge
Here I am sitting in one of the exits of the water pressure release point on Tsuujunkyo bridge. Just next to my feet you can see one of the wood corks which plugs the water release point. Even though the wood plug works, there is still a small amount of water which was trickling out; just enough to get my feet wet.
