Niyodo River, a clear stream in Shikoku, and a “submerged bridge.
\nA submerged bridge that hides in the water flow when the water level rises. Symbiosis with the abundant water volume rivers of the Shikoku mountainous region. I feel that human society has a mindset of obedience to nature. …<\/p>\n

As a Hokkaido-native, there are probably a variety of psychological motivations for me to travel to areas south of Honshu. In the Tokyo-Kanto area, I see the vitality of the capital city and its dense population, and in the Kansai area, I feel a sense of encounter with various aspects of “Japan,” such as the multilayered nature of time against the backdrop of its history.
\nIn this context, the encounter with Shikoku is a little strange. Although I had the “original experience” of working together with everyone at my company when I first started my career, after about half a century has passed and I have traveled with my family and as a couple, I find that I am most comforted by the “richness of nature” in the warmer regions.
\nThe Median Tectonic Line runs east to west across Shikoku, forming a mountainous region along it. The Seto Inland Sea region to the north has a larger population concentration. However, because the overall population size is not so large, huge forests continue to be preserved in the mountainous areas, and the abundant amount of water stored there produces “clear streams” when they flow. The Shimanto River is famous for its impressive name, but when I asked a person in Kochi to tell me which clear stream he was referring to, he immediately replied, “The Niyodo River.
\nHe also told me that there is an unfamiliar bridge called a “sunken bridge” across the clear stream. What is that? If you think of it literally, it is a bridge that disappears under the water. (Laughs.) A simple question: “Wouldn’t such a bridge serve no purpose? That is why we set out to search for it. The situation is as shown in the photo.
\nA submerged bridge is a bridge that is constructed only where water normally flows, called a low waterway or low water bed, and the floor plate is the same height as the land of the riverbed or high water bed, so that it can be used as a bridge when the water level is low but sinks below the water surface when the water level rises. In river administration terms, it is called a “submerged bridge. This one in the photo is called the Nagoshiya Submerged Bridge.
\nThe clear stream in the background is the Niyodo River, which is called a miraculous clear stream. It has been repeatedly selected as the “best water quality river in Japan” according to the results of water quality surveys conducted by the Ministry of Land, Infrastructure, Transport and Tourism. The river is also known by the nickname “Niyodo Blue” because of its high transparency, which makes the surface and bottom of the river glow blue.<\/p>\n

I did not challenge the bridge, but there were some people who drove their cars over the bridge. There is no particular distinction between sidewalks and roadways, and the speed of traffic seems to naturally match the speed of people walking. This also creates a unique atmosphere. I found out later that there are several sunken bridges like this in Hokkaido.
\nI think that we are living our daily lives with a sense of time that is constantly adapted to the expressway. I felt as if these clear streams and sunken bridges were telling us to “wait a minute.<\/p>\n","protected":false},"excerpt":{"rendered":"
