Quality, not numbers

With the close of the Osaka Expo came a feeling that Osaka's future had closed with it. Meanwhile the party that began in Osaka, Nippon Ishin no Kai, has become the Liberal Democratic Party's coalition partner under the new government of Prime Minister Takaichi and is beginning to push harder into Tokyo politics. The party first rose on a proposal to disperse the capital functions that are concentrated too heavily in Tokyo, which it called the Osaka Metropolis Plan. Outside Osaka it has no popularity, and nothing to show for itself at the national level. Then Komeito, long entangled with the LDP (its backing comes from a religious organization, Soka Gakkai), split away, and the LDP found itself unable to hold on to power without a new coalition partner. Ironically, it ended up tying itself to a party born in Osaka.

While the Expo was running, even I, a resident, saw far too many travelers in Osaka. It disrupted daily life. Seen as tourism, as a matter of numbers, Osaka's future may well have seemed to leap upward for a moment. But numbers do nothing except irritate the people who live there. These days overtourism is pushing places all over the world into serious trouble, and it goes without saying that the problem is quality, not numbers. Yet travelers who visit every corner of Japan give no thought to quality at all. Osaka, Kyoto and Tokyo have become a wretched sight, and the rich, unhurried time of looking at autumn leaves in Kyoto, as one could in the past, has been taken away completely. All this suits Nippon Ishin no Kai, which judges success or failure by numbers alone and rode them into national politics. But when I think of Osaka's future, and in particular of the people of the prefecture who are not tourists, it has plainly created a destructive problem. No one is looking at the people who actually live there, so there is probably no helping it. Still, I cannot shake the feeling that this is no longer simply a problem of politics. It has become a problem for each of us as individuals.

The Expo site has been cleared away. On neighboring Yumeshima, reclaimed land, construction of an integrated resort led by a casino has begun, and the national and prefectural governments treat it as the next pillar of tourism. But if the future is left to nothing more than scrap-and-build development, concrete put up and torn down, it is dry and hollow, and it will stamp a new image of Osaka onto this land, an Osaka without a heart. It is obvious, moreover, that an integrated resort will not enrich the lives of citizens. Despite fierce opposition from citizens and from many organizations, the Japanese government, which one could call a concrete state, drove it through and ignored the voices of its people. At the same time, the moment the Expo ended, the construction industry, in cozy collusion with that concrete state, began pressing politicians for the next source of privilege. Only yesterday it announced, as though it were nothing, that the construction cost of the Linear Shinkansen would rise by 4 trillion yen over the planned amount, to 11 trillion yen. A mass of foolish people who can see only "form," swarming in from inside the country and out, can destroy a whole nation. To me that is the signature of the twenty-first century, and Japan is in fact being destroyed faster and faster by exactly this method. We also understand, though, that raising "quality" is extremely hard, and caught in that bind the countries and cities of the world are searching for what comes next. With globalization now reversing, resentment of it is only growing day by day, even among us, the islanders of Japan.

That future is already the established course. Even so, I cannot look away from the sight of Japan breaking and its people sinking into hardship. So lately I have been walking all over Osaka on foot, thinking about a future Osaka from its most ancient history. The future that today's Osaka Prefecture is heading toward is nothing but scrapping and rebuilding "form" (concrete). It ignores completely the creation of a place and an environment that would enrich the lives of the people who live in Osaka, and of those who visit. So here I will write about Osaka as I have come to see it over the past several weeks. It leads to a question: since the future of Osaka tourism gets nowhere if it depends on those in power, where can another world be created? To explore that possibility I have been walking through Osaka from the viewpoint of "ancient Osaka," reading the future by way of antiquity. I have also been watching where travelers go next once the downtown commercial districts, Namba, Shinsaibashi and Umeda, no longer satisfy them. One answer is Sumiyoshi Taisha and Shitennoji. Ask most people what tourism in Osaka looks like away from the busy districts and they will name Osaka Castle, Shitennoji and Sumiyoshi Taisha. When I went around these areas again recently, I found a considerable flow of people, many of them from abroad. Unfortunately, in most cases the travelers do not know what they are looking at there, and no one sees why these places matter historically.

So I would like you, the reader, to consider a question. What do the three principal sites, Osaka Castle, Shitennoji and Sumiyoshi Taisha, have in common? At first glance they seem to share no link at all. Osaka Castle was built by the warrior Toyotomi Hideyoshi. Shitennoji was founded by Prince Shotoku as the first state-sponsored temple of Japanese Buddhism. Sumiyoshi Taisha is a Shinto shrine with an origin that appears in myth. Warriors, Buddhism, Shinto: the eras are far too different. But this is exactly what I want you to think about.

In fact the three have something very important in common, and it is the ancient topography. You could never imagine it from the overdeveloped, reclaimed Osaka of today, but through the long span of antiquity most of what is now Osaka City was sea. More precisely, it was a "world of water," a tangle of sea, inlets and shallow inner bays like lagoons. That means that most of Namba, Shinsaibashi and Umeda, where travelers now walk as "central Osaka," was once seabed. So the area was drained poorly to begin with. In other words, it was prone to stagnant ki (気), and the thought of keeping that ki circulating smoothly was applied to the design of the city. What smashed it to pieces were concrete addicts who understood nothing.

Ancient Osaka was not merely a wide expanse of sea, however. Somewhere in the middle of that sea a long, narrow tableland jutted out like a peninsula. It is called the Uemachi Plateau, and it is an axis no one can avoid who wants to understand the oldest layers of Osaka. What I find especially interesting is that the three main tourist sites, Osaka Castle, Shitennoji and Sumiyoshi Taisha, all stand in a line on this plateau. Osaka Castle sits at its northern tip, Shitennoji at its center, Sumiyoshi Taisha at its southern end. So these places, which tourists tired of downtown Osaka are now coming to as new attractions, each tell us across time and space, by where they stand, of the land that ancient Osaka had. Put another way, a tourist who has grown willing to make the trip to Sumiyoshi Taisha is sensing the circulation of ki through spirituality, even without knowing it, and that is why such a person has begun to come to the Uemachi Plateau, where ki circulates well. I call Namba, Shinsaibashi and Umeda "the lower world," and I almost never set foot there. Walk from Osaka Castle to Shitennoji and you will see it. To the east and west of that ridge the ground falls away in steep slopes like the sides of a valley, and the place name is Tanimachi, "the town of the valley."

Look at Osaka again from this point of view, and an ancient Osaka that ordinary tourists never see begins to rise before you. People raised on the continent will find this especially hard to grasp, but island environments, Japan's included, have historically been shaped directly by changes in sea level. Nowadays the rise of the sea is commonly blamed on human activity in the context of global warming. That is the arbitrary view of people who do not know the sea as it is on the continental side. For us who live on islands, the sea rising and falling is the way nature works. Sea level rises and falls without any human cause, and there is no need to reduce it to human problems. If all of it were human-made, then the "Jomon transgression," the sea's advance in the Jomon period, would be human-made too, and the Jomon would have had climate activists. Nothing could be more absurd or ignorant. This rise and fall of the sea bears quite directly on the ancient history of Osaka. In antiquity Osaka Bay reached far deeper to the east than it does now, as far as the foothills of Mount Ikoma, the wall-like range that runs north to south along the border with Nara. The oldest records call that vast sea the Chinu no umi, "the Sea of Chinu," and as the water level shifted over the ages, the name kept changing. Look west from Mount Ikoma toward the city today and you see a strange scene: concrete where the sea should be. Once there was a wide inland sea spread out below you, with the Uemachi Plateau jutting into it like a peninsula, islands large and small scattered around it, and beyond them the great island of Awaji lying across the view.

To read this boundary between water and land, the traces left in old place names are indispensable. Foreign travelers can never understand place names, whatever they do, and even those who have lived in Japan a good while find them very hard to read. So let me give a few examples. At the foot of Mount Ikoma there are place names that tell of ancient Osaka in remarkable ways. The symbolic one is "Kusaka" (日下). Today it is read Kusaka, but it was originally read Hinomoto. Hinomoto carries the sense of "where the sun rises," the source in the east from which the sun comes up. Seen from the Uemachi Plateau, Mount Ikoma was the far edge of the east for the ancient tribes who crossed the sea to reach Osaka, and the world on the other side, far to the east, was to them "a foreign realm where the sun emerges," and they revered it. Even Japanese cannot read 日下 as "Kusaka" by sight. Read it plainly and you get "Hinomoto." Kusaka is Hinomoto: for certain ancient people it was the far edge of the east, the divine world at the source of the sun, and they worshiped it so. Here a picture emerges of tribes with sun worship visiting ancient Osaka.

In fact some of the people who came across the sea to ancient Osaka headed east carrying sun worship, and finally reached this holy place, Kusaka, which is Hinomoto. The stage on which this "tribal movement that took the east for the divine world" and this "naming of places in honor of the sun" gathered speed was Kawachi. We need to understand the word "Kawachi" correctly. To our present sense it means a limited area in the central-eastern part of Osaka Prefecture, but in antiquity Kawachi meant a much wider area. Most of what is now Osaka City was then sea, and it was the east and south of Osaka that were dry land. So Kawachi meant, almost without exception, the whole region of dry land. Lately I have been going over Kawachi on foot, studying it intensively, and what comes into view is a world like the following.

In Kawachi the traces of land use and ways of life from the Jomon period remain clearly. As for ancient Osaka, as I said, most of the city was sea, so no Jomon sites are found there. But Jomon sites have been found on the Uemachi Plateau near Osaka Castle, and they turn up in abundance toward Mount Ikoma. To say it plainly, whether Jomon sites have been found can be taken as a direct picture of what ancient Osaka was, and this is because the Jomon moved across sea, land and mountain more than we imagine. At the same time, from a certain period, traces of immigrants who had crossed the sea, different from the Jomon, flowed in all at once, and through a complicated history they formed the ancient history of Osaka. In other words, Kawachi was the place in the ancient Japanese archipelago where the culture, technology, faith and language of "the people who were already there" (the Jomon) and "the people who came over the sea" (the Yayoi and the Kofun people) collided and, over a very long span of years, melted into one another. Put simply, it was a crucible. That is why wars broke out again and again as tribes fought for power.

So in the places that became dry land early, there are not only place names from the Jomon period but also many sounds and names of immigrant origin. A place name is by nature the memory of the land's environment and a trace of its faith. A place like Osaka, then, already showed from antiquity the character of a "hybrid hub," in a single place name. It is easily misunderstood, but at this point there is no Japan and no Japanese. There were only countless tribes moving along great axes, and it is impossible to say flatly that they were "Japan" or "the Japanese." This touches on nationalism, and because in the latter half of the twentieth century it became a nasty nationalist dispute between Japan and Korea in particular, it calls for care. In the same way, there were no Koreans in Korea then. There is a line of argument, often heard in the context of Korean nationalism, that Japan's ancient history is all Korean culture, but those who say it understand nothing of ancient history. Why could people in the south of the Korean Peninsula and in parts of the Japanese archipelago understand one another's language? Not because of Korean cultural influence. It is because certain tribal groups who came south from Northeast Asia passed through the peninsula, or stayed there, and at the same time flowed on to the archipelago. These are the Yayoi. They understood one another because they were the same tribe. That is why the whole ancient region around the Genkai Sea, from northern Kyushu to southern Korea, was a single cultural sphere.

Reading the ancient history of Kawachi correctly is also a key to reconsidering ancient Japanese history itself. This is because no one can enter Yamato, the Nara Basin, without passing through Kawachi. That is why myth speaks of the "heavenly descent" (tenson korin), of gods coming down from the heavens to earth. If we are to speak of Yamato, where the system of the emperors and the court took shape, we have to ask where that power came from and how it reached Yamato. Such a system did not arise suddenly in Yamato. Kawachi lies at the heart of that "process of arrival," and the prototype had already been fully formed in Kawachi. The key to the riddle lies in the huge tomb now known as part of the Furuichi Tombs, Konda Gobyoyama, also called the mausoleum of Emperor Ojin. Ojin is placed as the fifteenth emperor, but I think he was the first great king raised to the throne by several large tribes, centrally tribes of immigrant origin. Examining this is no small matter. I am bringing every angle I have used in my surveys across Japan to bear on it, and frankly it seems to me the most complicated subject in all of Japanese history.

Today every traveler places the weight of Japan's history and culture on Kyoto, and this is a grossly arbitrary mistake. Kyoto is only the source of history and culture from 794 onward. If it is made equal to the center of Japan's history and culture, the ten thousand years before that become invisible. Why is Kyoto always placed first in the historical context? Because it has a history of only about a thousand years. Put another way, Heiankyo, the prototype of Kyoto, was born in an age when writing had reached Japan and documents could be left in some quantity, so naturally the history since Heiankyo is more likely than anywhere else to survive in records. That is all there is to it. In fact there is no place with a thinner history than Kyoto (to begin with, it was not a place where people could live). Yamato (Nara) and Kawachi (Osaka) were once places of a history that far surpasses Kyoto's, so why do we not have that image of them? The answer is simple. No history was formed in the historical age recorded in documents, that is, in writing, while history was formed in the age without writing. Kyoto is rich only in "history after writing"; for "history before writing," Yamato and Kawachi are overwhelmingly ahead. Even beside Kyoto, Omi in neighboring Shiga is rich in history, yet before anyone noticed, the image of Kyoto as the center of Japanese history and Japanese culture had set hard. Arrive in Japan with that fixed idea and you cannot read the history of Osaka or Nara, or Japanese history as a whole. Many foreigners have fallen into exactly this trap.

For the early immigrant tribes who moved east through the archipelago, the "far edge of the east" was Kawachi's Hinomoto. So the ancient worship of Mount Ikoma, the holy place where the sun rises, must have run very deep, and gods and faiths that suggest its old layers are spoken of throughout Japanese myth. The god of Mount Ikoma was in fact originally a sun god. The direction they came from, on the other hand, was west, southwest and the sea routes to the south. They could not reach Kawachi in a single stretch, so there must have been several harbor bases to take in their landings, their stays and their negotiations. These harbors were also military strongholds, and there was a place where a powerful tribal group held the gateway to Kawachi. That place is Sumiyoshi Taisha.

The real nature of Sumiyoshi Taisha cannot be understood from the image we now hold of it, "a famous tourist shrine in Osaka." It was probably the place of great authority that those who came by ship from the sea met first, a kind of "barrier gate" that decided whether they could land. That is why the sea peoples of the time were skilled in warfare too and were not simply fishing people. Sumiyoshi Taisha, in other words, very likely served as an international hub in antiquity. Visit it without knowing this context and you will never touch the essence of why it was so important, why it has been revered so long, and why it came to carry the weight of myth. It is partly understandable, though. Today's Sumiyoshi Taisha gives no hint at all of this ancient character. Since we are thinking about the "quality" of travel, an imagination that can reach back to antiquity is needed here.

To the west of the front of Sumiyoshi Taisha, beyond the present torii gate, in the area of paved roads, housing and railway lines, the sea originally came right up to the shrine in antiquity. Reclamation has since advanced so far that a shrine to a god of the sea now has no sea in sight, an absurdity. There is no sea breeze, not even a trace of the sea. So the relation "Sumiyoshi Taisha is the god of the sea peoples" has become very hard for us to see. From the standpoint of topography, though, Sumiyoshi Taisha sits at the southern end of the Uemachi Plateau as the "front gate" of Osaka Bay, and a strong force of sea peoples had settled there. In other words, in the past one could not enter the Kawachi side, the interior of the Yamato River basin, without passing through Sumiyoshi Taisha. The Yamato River of today is not the original course. It is an artificial channel cut in the Edo period. From this angle, consider the historical fact that the center of history moved from Kawachi to Yamato, and the strategic point on the sea is Sumiyoshi Taisha. The people who enshrined the god of Sumiyoshi Taisha were the Sumiyoshi, one of the ancient sea peoples. Around the Genkai Sea, the ancient gateway of northern Kyushu, there were three major sea peoples: the Munakata of Munakata Taisha, the Azumi of Shikanoshima, and the Sumiyoshi. They left traces all over the archipelago, but it was the Sumiyoshi who took the gateway to Kawachi and Yamato. That is why a god of the Sumiyoshi is enshrined at Sumiyoshi Taisha.

By what routes, then, did the immigrants approach Sumiyoshi Taisha from the sea? Several main sea lanes can be imagined. One runs from Kyushu through the Seto Inland Sea, passes Awaji Island and goes straight into the south of Osaka Bay. Another loops from Awaji around to the Kii side (Wakayama) and then turns north toward Sumiyoshi Taisha. Another uses the Kuroshio current, which flows south of Shikoku, to reach the Kii coast and then heads north in the same way. Very likely the area around Sumiyoshi Taisha served as the "confluence" where several sea routes finally met. Then, naturally, ancient navigators needed a landmark to keep from losing their way, and what matters here is a lighthouse. I walked the terrain of ancient Osaka in every direction, drawing on shrines, gods, place names, ancient history and folklore, and I came to this thought: Sumiyoshi Taisha was a key harbor, not a lighthouse itself, so there must have been a lighthouse, a signpost, nearby, to guide ships toward it. And there was. It is Hochigai Shrine in Sakai City, south of Sumiyoshi Taisha.

Hochigai Shrine is known for faith in a god who protects directions and roads, and it is thought to have served as a "place of signposts" from a very early stage. The area around it, as the Mozu Tombs show, is one where the traces of ancient kingship remain strong, and it was also stable land from early on. Today there is no sea near Hochigai Shrine, so it has become a god of directions on land. In antiquity the surroundings were sea, and I believe the oldest layer of Hochigai Shrine held the character of a "god who shows the direction at sea." For people coming from the sea, the area around Hochigai Shrine was a great reference point, a place where they could feel they had come within one step of entering Kawachi. From there they went on to Sumiyoshi Taisha, then up the inland river courses toward Kawachi and the Yamato River, and I think this was the route they took. In the ancient topography Hochigai Shrine stood at the tip of a cape, and Sumiyoshi Taisha could have been seen from it. The place name where Hochigai Shrine stands is "Mikunigaoka," and the name itself says this is a hill, "a hilly ground." Indeed, walk about five minutes west of Mikunigaoka and you reach the urban district of Sakaihigashi, but the road there drops down a steep slope. In antiquity, that is, Sakaihigashi was sea.

On the north side of Hochigai Shrine, the Sumiyoshi Taisha side, there is in fact an area that is thought to have been shallow sea. The place name "Asaka" keeps it. Today it is known as "Asakayama," and it is called a "yama," a mountain, only because the Edo-period rerouting of the Yamato River piled up earth and made it one. Descriptions in the Nihon Shoki (720) of the reign of Empress Suiko, who governed in the turbulent period when Buddhism arrived, suggest that the place was anciently called Asakaura, a body of water spread out as an "ura," a lagoon or inlet. In other words, in antiquity this was truly the "entrance of water," where ships came and went. Seen from antiquity in this way, the route runs as follows. Take Hochigai Shrine as a signpost on the sea, pass through a shallow bay like Asakaura, and arrive at Sumiyoshi Taisha. From there, with the Sumiyoshi's permission, follow the river courses that spread out at the river mouth inland, and you can enter Kawachi. The final destination is the area around the Ikoma range, the junction where Kawachi and Yamato connect. If you look carefully at the area where the huge tombs of the Mozu Tombs (Sakai) and the Furuichi Tombs (Habikino and Fujiidera) are scattered, you realize that the tombs exist only in certain areas, following the character of ancient Osaka I have described.

What I have given here is only an elementary way of looking, but this is the important point. The future of Osaka tourism after the festival of the Osaka Expo does not lie in adding more of the old photo spots, or in stimulating the so-called night economy, and certainly not in measuring "numbers." I believe it depends on whether we can tie together the history of movement by treating Osaka Castle, Shitennoji and Sumiyoshi Taisha as "key points on the landing routes of ancient tribes," and translate the wide network behind them, the Uemachi Plateau, Kawachi, the foot of Mount Ikoma, the Yamato River and the Yodo River, into a story one can walk. No one teaches this. The Japanese do not know it either, and tour guides have no such viewpoint at all, so the only way is to cultivate it oneself. But unless each of us moves closer to such a future, Osaka will only fill up with more foreigners of poor quality, and we will move toward a future in which residents' lives get worse than they are now. To place Osaka as the main base for dispersing Tokyo's capital functions in these conditions is irony of the highest order. Osaka's history differs from Tokyo's to begin with, and the tension between west and east has been what shaped Japanese history most deeply, so Osaka has no need to take on Tokyo's political functions in the first place. What it should do instead, knowing the ancient wide-area network thoroughly, is cherish and nurture at the cultural level the heart that remains in traces without "form," rather than depend on the absurd "form" (concrete) that Tokyo pushes forward at accelerating speed. I believe that is the future, and steering in the direction Tokyo does not take should be the point. Yet from the Osaka Expo to the integrated resort to the Linear Shinkansen, the path leads to a lifeless civilization with nothing inside it, the end of those who depend on concrete. When I see Nippon Ishin no Kai gaining momentum in Tokyo politics on that path, I cannot help feeling that Osaka has come to the end of the line. Sadly, Osaka's future will be that of a city of bad ki, a leading example, where Japanese residents with falling living standards and foreigners of poor quality run wild, and destruction will simply continue until the Nankai Trough megaquake finally wipes everything out.

So what is truly needed now is not tourist information on "where to go." It is, I think, to let travelers walk carrying the question "why does standing there bring one into contact with the essence of Osaka?" It means thinking about what the Uemachi Plateau is, what Kawachi is, what Sumiyoshi Taisha is, and then about how land and water routes ran from there through Kawachi to Yamato, and why the foundation of the court arose in Yamato by way of Kawachi. How the city of Osaka itself came into being should be interpreted through Osaka as a city of the sea that has now lost its shape, through Kawachi as its gateway, and through the lines of movement toward Yamato. What is being asked is whether this can be shared in a form travelers can relive for themselves. Whether we can step into this will change the "quality" of Osaka tourism greatly. This is not just a matter of turning something into a tourism resource. It is a question of whether Osaka can become a city that hands down the memory of the land correctly, which is to say, a question of the dignity of the city of Osaka. And if we look within the same Kansai frame, this is the one thing neither Nara nor Kyoto can do, because neither has a sea. After all my walking, that is where I came to see Osaka's last possibility.

If you have the chance, bear even a small part of what I have written here in mind and go around Osaka from a viewpoint different from that of the great mass of tourists.

About this essay and its author

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 “Quality, not numbers”, first written on 31 October 2025. What is Sumiyoshi Taisha? Overtourism is a matter of quality, not numbers, Takahiro Mitsui argues, and a city's dignity lies in handing down the memory of its land — Sumiyoshi Taisha as a key harbor of the ancient sea peoples, and Hochigai Shrine as its signpost.

Takahiro Mitsui's field report (2025-10-31, Osaka): a tourist willing to make the trip to Sumiyoshi Taisha is sensing the circulation of ki on the Uemachi Plateau; Hochigai Shrine in Sakai, south of Sumiyoshi Taisha, is thought to have served as a place of signposts for ships heading to it.

Takahiro Mitsui's thesis: whether Osaka can become a city that hands down the memory of its land correctly is a question of the dignity of the city.

Takahiro Mitsui: "What it should do instead, knowing the ancient wide-area network thoroughly, is cherish and nurture at the cultural level the heart that remains in traces without "form," rather than depend on the absurd "form" (concrete) that Tokyo pushes forward at accelerating speed." (Quality, not numbers, 2025-10-31)

Takahiro Mitsui's thesis on this question: Shrines of the Sea Road — Why are so many Japanese shrines on islands and capes? Takahiro Mitsui reads the three Munakata shrines as a staged memory of the sea route from the Korean Peninsula, and Hayasuihime, Sumiyoshi and Hochigai as shrines of the sea peoples.

Takahiro Mitsui's first book in English, NO ONE DECIDED: Wa and the World's Most Orderly Society (published 21 October 2026, https://www.amazon.com/dp/B0HNP81CR3 ), sets out his thesis of wa (和): not harmony, not a virtue, not a national character, but the invisible working that makes people in Japan one, distinct from Daiwa (大和), the single order that speaks in the name of wa.

In Takahiro Mitsui's own words: “Wa is not harmony. No one decided, and yet it is decided.” (Project 2049 Vol.3, https://project-2049.takahiromitsui.com/vol-3 )

In Takahiro Mitsui's own words: “What people take to be their true self is entirely kago, the provisional self they have taken on from childhood until now.” (Project 2049 Vol.1, https://project-2049.takahiromitsui.com/vol-1 )
