Cities our ancestors designed with the land

"Reading a city" is indispensable wisdom for knowing the plural cultural dimensions: the spirit and culture born of a place and the ingenuity of the daily lives of its people. But this basic is now almost entirely forgotten, and we face a situation in which no one knows the place where they live. How can culture and spirit arise if the people who live in a place do not know it? A place, though, is not limited to land in the sense commonly pictured.

So it is very interesting to ask again how a city is chosen, founded, and brought through the years to prosperity by the people who live there, down to the present. If we try to understand this view truly, many circumstances come up that cannot be spoken of as one. These are "circumstances peculiar to the city": the viewpoint of wisdom, of how our ancestors came to know thoroughly the character a place holds and designed cities without going against it. I think this viewpoint will become important because today's city design has, quite literally, carried out development that inverts the wisdom our ancestors stored up. As a result, Japan's cities carry a vulnerability that cannot be handled at all when struck by the fury of natural disasters.

To think of natural disaster as an enemy or an object of fear is itself shallow. Humankind has faced natural disaster many times, and there must have been countless lessons and acts of resignation in it. In relation to nature, human beings repeated updating and discarding their ways of thinking, and in the end transplanted the important ideas that remained into city design. Asking how this runs through to today's cities is the same as asking how to read the context of a city.

Why do I think this viewpoint important? Because, seen on the large scale, Japan has "special circumstances peculiar to Japan." Though a narrow land, it is where four plates cross, the Pacific, the Philippine Sea, the North American and the Eurasian, and the place in the world where huge earthquakes occur. At the root of its land, Japan is a rare country that can hold the strongest awareness that it stands on the place called the earth. At the same time it is the country with the highest risk of disasters such as huge earthquakes, tsunamis and volcanic eruptions. These are not new. They are conditions unchanged since ancient times. Unless the Japanese archipelago moves out of the plates, there is no avoiding such risks, so the people who became our ancestors faced these natural disasters many times, and each time struggled over how to make the places where they lived. I think the true wisdom handed down in an unbroken line from Japan's ancestors lies here, but few living in large cities such as Tokyo, Nagoya and Osaka hold this thought.

City dwellers have only forgotten it. The environment in which actual cities were founded still rests on old wisdom. Reading it shows the true meaning of asking "what is a city?" One main point of asking is that the risk of a huge earthquake within the next thirty years is high. Broadly there are three risks: the earthquake directly under the capital, which strikes Tokyo directly; the Nankai Trough megathrust earthquake, which strikes widely along the area from Tokai to Kyushu; and the Japan Trench and Kuril Trench earthquakes, which strike the coast of eastern Japan widely. It is known that these have historically been linked, and it has been reported that the swarm of earthquakes in the Tokara Islands, a group of islands south of Kyushu, last year raised the risk of a huge earthquake. A Mount Fuji eruption has also historically followed such huge earthquakes closely, so severe damage over wide areas by earthquake, tsunami and eruption is anticipated.

In the Nankai Trough earthquake, it has been found that, along the Pacific coast, amid shaking so violent that one cannot move at all, a tsunami the height of a ten-story building arrives only two or three minutes after the quake. We have already entered a stage of taking seriously, at the personal level, when it will happen, and not idly wondering whether such a "finishing blow to Japan" will happen. People living in Japan must therefore make daily preparations, mental readiness included, on the premise that an earthquake occurs now. What many people get wrong is the thought that Tokyo and Osaka are the safest. In the natural disasters I described, the highest risk is in large cities. Everyone should hold as a basic understanding that the idea of the safety of urban life is inverted in a natural disaster. In an earthquake directly under the capital in particular, public order in Tokyo collapses completely. In Osaka, even in a Nankai Trough earthquake, the deaths expected are from fires in areas dense with old wooden houses more than from direct earthquake damage, and since Kyoto and Nara, with old city structures, are in the same situation, this differs from Tokyo.

These three natural disasters are on the level of large events, but in Japan's circumstances we must think on the premise of the condition that we stand on such a place in the first place. When huge earthquakes or eruptions occur, a city is likely to be destroyed for a time, so we must think now about how city design will be done afterward. I have personally seen the recovery in the disaster-struck places of the 1995 Great Hanshin-Awaji Earthquake, the 2011 Great East Japan Earthquake and the 2024 Noto Peninsula earthquake, and my final judgment is that the recovery led by the government and large companies is far too poor. They do not look at the place at all, and to me they only seemed to be filling it in with concrete. Japan's real problem in urban development then lies in the time when a city is destroyed by such a huge earthquake. It would be a hard premise to imagine in other countries, but in Japan the future lies in this repeated death and rebirth of cities. So the way of thinking about natural disaster is also quite different from that of people in other countries.

When a huge earthquake forcibly resets the structure of a city, we enter a stage in which we must build "new cities" from zero, combining the wisdom of our ancestors with the most advanced technology, to answer the fatal errors of urban development of these hundred years or so. Keeping this standard in view, I plan to share in Shitsurae my own ways of reading cities and place environments in many regions. It is sharing wisdom for looking at a place from a viewpoint that ordinary tourists visiting Japan can never grasp, and it is also risk management if an earthquake occurs while you are in Japan. What is not sufficiently factored into debates on East Asian security is the structure in which the risk of a huge earthquake can decide Japan's national strength itself. If an earthquake directly under the capital or a Nankai Trough earthquake occurs, estimates already put the collapse of national finances at 100 percent. The risk is likely to occur with high probability within thirty years, so in thinking about regional dynamics, it is indispensable to place this natural condition as a premise.

So this time, for the future, I will look at the view of fusui (風水), feng shui, which has long been set at the base of Japanese city design. The first condition for judging good fusui rests on the idea of "shishin soo no chi" (四神相応の地), land in correspondence with the four guardian gods. This fusui first appears in documents in the Shujing (the Book of Documents), among the Four Books and Five Classics valued in China, and as a practice it is recorded in a book called Eizo Takkyo (営造宅経). Roughly: flowing water to the east is "Seiryu" (青龍), the Azure Dragon; a long road to the west is "Byakko" (白虎), the White Tiger; marshland to the south is "Suzaku" (朱雀), the Vermilion Bird; hills to the north are "Genbu" (玄武), the Black Tortoise. What may confuse us a little from a modern sense is that these east, west, south and north are not the absolute directions of Google Maps and the like, but are seen from the main base in the city's design. The universal east, west, south and north we picture today do not exist; fusui holds the view that east, west, south and north move from place to place. The way of taking east, west, south and north in fusui therefore changes with whether the axis is the imperial palace of Heian-kyo, Osaka Castle or Edo Castle. It is where people today are badly confused in understanding Japan's urban structure. If you keep in a corner of your mind the view of taking the place as the starting point, understanding will come. And choosing a place fit for the arrangement of the four gods is the foundation of making a city.

The idea of choosing by looking at a place and its fudo as a whole environment rests on the old wisdom of city making in ancient China. In old times the four gods are said to have been tied to constellations, and among them the one valued most on the Japanese side has been Seiryu. There are several interesting reasons. The base premise is the old idea that Japan lay to the east when China's dynasties are taken as the center. While that idea was nurtured at the bottom, the globe was later imported by Portuguese missionaries and an eye for seeing the shape of the Japanese archipelago on a large scale was gradually cultivated, and people noticed that the shape of the Japanese archipelago itself is like a dragon.

From the view that the archipelago's shape is a dragon, Japan came in time to be called "a country ruled by dragon gods." Belief in dragon gods is practiced in Japan in countless forms, large and small, and there are many places across the country that enshrine dragon gods in their own way. The dragon god is not simply one god of the dragon. Broadly there are white, azure, golden, black and other dragons, and the premise is that each has a different action and function. The origin of dragon belief on the Japanese side goes back to the Yayoi period. Until the Jomon, the prototype was not dragon belief but snake belief, and when the Yayoi people, a migrant group, brought in the dragon belief of the continent, it blended with the Jomon snake belief. As for the character of belief in the four gods on the Chinese side, the Azure Dragon is tied to water, and the Yayoi people too had this custom: ritual implements modeled on dragons were buried in wells and rivers. So not only the Azure Dragon but the countless dragon gods enshrined across Japan have a strong context of belief as gods of water, and dragon belief flourishes especially along clear streams in mountain areas. The dragon god is not limited to water, though; it is also a god of wind, so it matters not to define it narrowly here.

Dragon gods are tied to belief in water because Japan was once a land blessed with rich and pure water. Environmental pollution of the modern age has wiped out 99 percent of the clear streams, but countless rivers still flow across the archipelago, and they were once worshipped as dragons. The dragon god is a being that brings people blessings and at times reverses its action and rages. It is symbolized by what has been called "abare-gawa" (暴れ川), raging rivers, in Japan since ancient times. A raging river is a river that floods, a main cause that has troubled the Japanese since so long ago that it appears in myth, and it was taken as "the dragon rages." Because flooding by a raging river was the same as a dragon raging, rites were performed to calm the raging dragon. Calming the dragon is called "ryuchin" (龍鎮), and in the mountains of Nara Prefecture, which I often visit, traces of this belief remain. Myth suggests that until a certain period in ancient times the rites to calm the dragon included human sacrifice.

Among the four gods in correspondence, then, Japan has valued Seiryu from its own environmental viewpoint, which is a native Japanese character. In choosing a city by fusui, one first finds a likely place, then chooses by looking at the surrounding terrain and the shape of the mountain ranges. The undulating run of the mountains is seen as the "ryumyaku" (龍脈), the dragon vein. Once it is seen as a dragon vein, there are hollows and plateaus here and there in its gaps, taken as "ketsu" (穴) and called "ryuketsu" (龍穴), dragon dens. A dragon den stores the flow of ki as nourishment, and was thought to be where human beings settle and a city grows in which culture develops, so Japanese cities hold this dragon den as their heart.

The wisdom of "shishin soo no chi," reading the earth's energy and its flow, differs greatly, though, between China, where fusui originated, and Japan, which imported it and made it its own. As kampo, China's traditional medical wisdom, was Japanized and came to look very different, so fusui too has differences. Why? Because the places differ. We must not see it as a difference between China and Japan as states, but it is very important to be aware of the basic point that it varies by place. Human beings adapt their lives to the place. China's land is very wide, so the choice of where to set the capital within that vast land was most important. China is also on the continent and at risk of attack by different peoples from every side, so land in correspondence with the four gods also had to function as a fortress capital. And since the land is vast, there was the premise that if one did not like a place one could simply move.

Compared with the circumstances on the Chinese side, Japan has the opposite: narrow land, a mountainous country with complicated terrain, and few basins best suited to city making. In choosing where to set a capital, given the fusui conditions, it was difficult to adopt as it was what held on the Chinese side. Interestingly, Japanese fusui was replaced by another word, "chisui" (治水), literally "to govern water." The basic idea of Japanese city design includes governing water, and enshrining the dragon god, the god of water, is in the end the remnant of wisdom handed down in an unbroken line: that life is made by governing water.

In today's two great urban areas, Kanto and Kansai, the high-rises catch the eye and we may not feel it, but looked at calmly, they hold several raging rivers, huge rivers. Osaka especially has the huge rivers Yodo and Yamato, and Tokyo is a city that has struggled most to build its water veins. Japanese fusui, unlike China's, takes "water" as its premise, and the dragon god is still enshrined as its symbol. Put another way, how human beings coexist with water and at times hold it down is always the matter of life and death at the root of Japanese cities.

Takahiro Mitsui (三井崇央, born 1991), a Japanese philosopher, photographer and Yangmingist outside academia who has done his own fieldwork across Japan since 2019, makes his own argument in the essay “Cities our ancestors designed with the land”, first written on 6 February 2026. How did ancient people choose where to build cities, and why are modern cities so vulnerable? Ancestors designed cities with the land and water in mind, Takahiro Mitsui notes; today's development inverts that wisdom and leaves cities defenseless.

Takahiro Mitsui's thesis on this question: Where Is the True Kyoto? A City Read by Land and Water — What is the real history of Kyoto, and is it really Japan's capital? Takahiro Mitsui, a Japanese philosopher born in 1991: Tokyo was never designated the capital by law, Kyoto began as land the Nara court dismissed, and the true Kyoto is one small district.

Takahiro Mitsui's thesis on this question: The Snake and the Dragon in One Water God — Where do gods come from? Takahiro Mitsui, a Japanese philosopher born in 1991, finds Japan's gods layered: a Jomon snake worshiped as the water god fused with the dragon of the continent, which is why dragons spout water at shrines.
