The tearoom as a mirror

Yesterday's essay began from a question: how does culture come into being? Taking sado (茶道), the way of tea, as its axis, it laid the groundwork for a philosophical comparison of chanoyu (茶の湯), the "hot water for tea," and sado. A suspicion arises here. Perhaps the two are alike in appearance and different in kind. The suspicion is, by instinct, correct. The wall that people today run into in the Japanese tea ceremony is the same wall they meet in any other practice that carries the suffix "do" (道), the way, whether martial art or performing art. That wall lies buried deep, and because it has never been made visible, it drives the confusion that fixes the world's impression of Japanese culture as something rigid and severe. What is it?

Japanese culture has been discussed from many angles, at home and abroad, but I see little attention to the risk that discussing it as a single thing is already a way of ceasing to be culture. A profound spirit runs beneath it. That spirit is hard to grasp historically, and it has been distorted, led astray and estranged from its essence many times over, so it cannot be stated in a word. Yet there is a passage through which it can be understood: Japanese-style Confucianism. In this essay I want to present a philosophy of culture by asking whether this still elusive thing called Confucianism should be seen as kanno (感応), a resonance between hearts, or as an adhesive.

I begin with what I touched on briefly at the end of yesterday's essay. In the martial arts there is an important phrase, shin-gi-tai (心技体), mind, technique, body. I explained that technique is born precisely because mind and body are not separate. Seen from the other side, it means that nothing goes well once mind and body are divided. In every "way," whether martial art, performing art, philosophy or faith, the question of separation and non-separation sits at the foundation. Conversely, all of history, culture, philosophy and technology, our own age included, can be explained from this point. Put simply, the present age is a system built on extreme separation.

Let me give the main point first. I believe Confucianism was taken in precisely so that mind and body, held as non-separate, could converge into a "way." More exactly, I suspect it was less a conscious adoption than the working of some primal movement peculiar to East Asia. That movement was systematized as Confucianism across the dynasties of China, which civilized early, but in Korea and Japan too there must have been a movement toward something close to it. The adoption of Confucianism as such is a later idea. But from its origins and through its transformations, a ground already Confucian in kind, and deeply compatible with it, had formed of its own accord.

Look at the Confucian side of today's traditional culture and the problem is plain enough: strict manners subdivided until no amateur can follow them. What matters, though, is that a "way" cannot come into being if one acts as one pleases, without restraint. The habit of judging everything in black and white is what distorts culture. Here too lies the most troublesome problem of individualism. Modern individualism has been turned upside down precisely because it ignored this fissure. So to become a "way," one begins with the convergence of mind and body, or, put another way, by driving restraint into one's own conduct. The repetition of daily life becomes habit, and in that habit the source of kata (型), form, is born. This alone shows that culture does not arise from a purpose set by a conscious subject. Culture exists in a configuration that lies in neither the conscious nor the unconscious. And there is in fact no teaching that gives kata more weight than Confucianism.

As the Book of Rites (Liji; in Japan, Raiki) already shows, kata were subdivided, fixed and laid down in minute detail in ancient China. Dai Sheng compiled it from the writings on ritual gathered by Confucian scholars between the Zhou and Han periods. I have never met anyone in Japan today who reads it, yet there was a time when reading it was a matter of course for anyone who pursued learning. The book is a long list of finely divided teachings, and at a glance the modern reader falls back on stale complaints: it is stiff, it is a bother, why must so much be decided, there is no individual freedom. That way of looking is the greatest misunderstanding of Confucianism. I grant that Confucianism has sides that invite it. But the real problem is the attitude that settles things arbitrarily in black and white. In the theory of yin and yang, yin is yang and yang is yin. They are not a separation into "yin and yang" but non-separation. Ancient China called the source of this non-separation taikyoku (太極), the great ultimate. We must not forget that view in Confucianism either.

To overcome the misunderstandings about Confucianism, I think we should take as our first premise that without kata the heart cannot be settled. I have come to think lately that this is what we most need in order to live today. The deep reason this age has come to doubt individualism itself, as I see it, is the confusion of a freedom that ignores kata. As I wrote yesterday, kata is not the same as formalism. What kata contains is spirit and form, and since spirit and form appear as non-separate, kata becomes their source, and the source of kata is the heart. When the movement of the heart regulates itself naturally through habit, kata, which is spirit and form, stands in a state of non-separation.

Without insight into the heart or into kata, however, most people try to cultivate spirit by arranging form, or the reverse, and the mistake that form arises once spirit is cultivated is rampant. Ours is the age in which this has reached its greatest excess in human history. We have broken down from within so completely that we do not notice we are at a dead end. Each of these merely clings to one side or depends on it. The essence is non-separation, so a "way" is attained only by creating a circulation in both directions within oneself.

Linear time is nullified here, and time and space converge in non-linear time, but that is hard enough that I will leave it for now. In short, since the modern age people have grown clever only in the head and think logically about everything, far too much. The cause is the worldwide spread of the university system, and the price of people losing their way of living is very high. Now that the earth is filled with people who have domesticated themselves into a society that can only look outside for knowledge, everything has to be reset once. That is the underlying problem. Yet the key to breaking through this closed-in feeling lies, in fact, in Confucianism, which is generally thought the most logical and the most confining.

If the stream of Zen aimed at reaching the state of "nothing" (無), I see Confucianism as the state that lies beyond it. Zen became a worldwide current because it was born of Japan's own cultural metabolism. In the same way, what will draw attention is not Confucianism in its Chinese roots but what can be called Japanese-style Confucianism. As I have suggested several times in Shitsurae, though, this Confucianism cannot be grasped as a single thing. Broadly it divides into the Zhu Xi school (朱子学) of the Song dynasty and the Wang Yangming school (陽明学) of the Ming. The Confucianism now known to the world in Japanese society and its systems sees only the bad side of it, so it is natural that people struggle to understand. No one is looking at Japan itself, or at the Japanese themselves.

Everything begins with becoming aware, thoroughly, of the non-separation of spirit and form. In this invisible realm of non-separation there is the movement of the human heart, and kata is its outline. The movement of the heart becomes kata, and spirit and form, the content of kata, arise dynamically. They are not problems to be thought about separately, each in a relation of separation. Today, though, we cannot avoid the tendency to separate them, and the human spirit is torn apart here. In medicine the term "integrative medicine" was fashionable for a while, but I do not believe in the concept of integration itself. Integration presupposes joining together concepts that were separate to begin with. Non-separation is not integration, and that point matters. The idea is entirely different.

What we should ask is not why the Book of Rites and the Confucian classics list kata so endlessly, a question born of distrust. We should ask what the source was from which the Book of Rites itself arose, and gain insight into it through what the text says. That is the absolute condition for understanding the Japanese "way." A theory of Japanese culture without an understanding of Japanese-style Confucianism is always an empty shell.

Confucius, in fact, already said it in the Analects: "A man who is not humane, what has he to do with rites?" This is exactly what I want to say. Honestly, if everyone in the world understood these words, I would not need to write such difficult reflections, and intelligence would return to its right direction. These words describe not only Japanese culture but the root of culture itself. Put in my own terms for this essay, the meaning is: if you are human and have no compassion, what use are spirit and form? Jin (仁), humaneness, is the greatest theme of Confucianism, and for Confucius it was ko (孝), filial devotion to one's parents, and tei (悌), devotion to one's brothers. The basis of the compassion that all human beings share is care for one's parents (ko) and care for one's siblings (tei), and doing these day after day is jin.

Many people find Confucianism hard to approach, and the chance to read the Confucian classics has almost vanished. I keep asking myself what a cultural theory can be trusted with when it lacks the discipline of facing its own origins. But as I said above, neither Confucius nor Mencius says anything especially hard. People find it hard because, as in Confucius's own day, they understand and do not act. Confucius criticized this understanding without action without mercy.

With this basic course as our axis, let us look at a Japanese concept that is a typical error: wabi-sabi (侘び寂び).

I loathe the word wabi-sabi in its modern sense, because even Sen no Rikyu (1522-1591), the founder of the way of tea, did not practice chanoyu with such a shallow aesthetic in mind. I know that wabi-sabi, entirely estranged as an aesthetic, is popular as a catchy trend, but when we cling to aesthetics the root disappears. And people who are seriously and actively exploring what comes next surely do not want these childish excuses that cling to the old aesthetics. I am one of them. If anything, we must not be led astray by the beauty of a word's sound when we look at aesthetics, because that beauty is only the decoration of an age.

Rikyu in fact criticized those who enjoy only the colors that can be seen, without knowing that the flowers and the autumn leaves of the world are in their own hearts. He said such people cannot reach sabi (寂び). The true meaning of wabi-sabi is that it is not something that has been signified. Modern people, who can see only what has been signified, cannot grasp this meaning and cannot escape the context of consumer culture.

If one believes that only showy decoration is artistic sensibility, one cannot understand the essence of the Rinpa school of painting, which is inseparable from tea. The line falls between seeing the seemingly showy Rinpa paintings as an aesthetics of form alone or as spirit. As I said above, we have to see them through non-separated kata and the original heart.

Rikyu lived in the late part of an age when warlords fought over supremacy in every region. Oda Nobunaga (1534-1582) stood as leader, and his retainers Toyotomi Hideyoshi (1537-1598) and Tokugawa Ieyasu (1543-1616), the men who would unify the country, had already appeared. At some point it became customary in Japan to call this age the Warring States period, but the name is the source of a great misunderstanding. There were wars, certainly, but they did not fight every day, and for most of Japan the days passed in perfect calm, unchanged. The warlords, too, were not brutes who wielded violence without restraint. They had characters tempered by severe self-discipline. Nobunaga is commonly mocked as the lowest of men, but he was in fact a man whose own spiritual discipline gave him the gifts to rise young through an age of turmoil.

We today cannot begin to gauge the hearts of warlords who lived in the intense tension of that age, never knowing when a rebellion might assassinate them or whether their castle might burn down tomorrow. That is exactly why chanoyu, the source of sado, was sought. Culture cannot develop without the demands of its age, and we have to look again from this side. The principle is exactly the same today. Rikyu simply answered that demand, in a realm that was not his own self, the demand of the age.

The noisier the outer world becomes, the more strongly human beings seek an inner world in which to be at peace. Most, of course, sink into the noisy outer world and lose themselves, but those who try to live sincerely always seek the inner one. And it must not be anything special. A warlord had to move about the provinces, command armies, and govern his castle and the town below it. He was busy beyond measure. In that age Buddhism had gained enormous power and worked behind the scenes, while Portuguese missionaries brought in the newest arms, guns, maps and telescopes, and worked in the shadows, trading them for permission to preach. A warlord had a great deal to keep an eye on. In the midst of this he needed a habit for daily spiritual discipline, and at the same time he needed lavish, splendid tea gatherings as social convention to show his authority to the world. We must not overlook that the source of chanoyu lies in the former.

However famous Rikyu was, no warlord could make Rikyu's tea gatherings a daily habit, since Rikyu moved almost every day between Sakai, his base, and Kyoto (Hideyoshi did try to make it daily by keeping Rikyu close). So tea rooms began to be built in various places, and inside castles too. A tea room was never a space for practicing the way of tea in a merely functional sense. It is a place where, with every decoration stripped away between human beings, one existence faces another in a life-and-death confrontation. Under intense tension the host receives the guest and sublimates the spirit with the instrument called tea. The swaying of the heart in the tea room, the way the heart is held, is the essence of host and guest in sado, and the host corrects the guest's swaying heart. This is not the empathy we speak of today. It is the resonance of hearts. Nothing is said directly. They resonate through motion (動) and stillness (静), and it was there that etiquette was born.

The nijiriguchi, the crawl-in entrance Rikyu invented, makes this plain. It is commonly said that Rikyu's tea rooms were designed so that one has to set down one's sword and bow one's head on entering, so that status counts for nothing and all are equal. That is a modern beautification, and typical of the ignorance of culture in scholars who can see only what has been signified. It has nothing to do with Japanese culture. What Rikyu truly had was the readiness to face every ornament that human beings wear. Consider his own day. His company was warlords who were achieving national unification, and he had to deal constantly with hostile forces who resented them. Add greedy merchants who stirred the age, and Portuguese missionaries who wanted to gain their own concessions by selling weapons. Rikyu lived in a complex world where self-interest and private scheming crossed. In that world, himself a merchant, he used chanoyu to practice how to set the heart right, within that world of his own, his tea room. In a sense Rikyu practiced something close to what a Confucian sage does.

I feel this is a point no one considers. I believe the way of tea that Rikyu brought to completion is the practice of something Confucian, more than it is Zen. When I look at the wisdom in Rikyu's tea, though, I see a complex blend, with Buddhism and Confucianism built on a thoroughgoing yin-yang and five-elements theory (陰陽五行論). Nothing can be spoken of in such sweeping terms as tea.

So those who drank Rikyu's tea needed an active daily discipline of casting off every decoration. As now, the "way of tea" was already in an inverted state in his day, not understood even by tea masters. Rikyu himself judged Tsuda Sokyu (?-1591) and Yamaoka Somu (?-1595), fellow Sakai merchants and famous tea masters, in these words: "They are tea masters known to the world, but they have not reached the deep truth of tea."

On entering Rikyu's tea room, one casts off every label and decoration, every external ornament, one's own conceit and pride. Unless one has trained oneself to overcome these through daily discipline, one cannot know the heart of Rikyu's tea. If one cannot cast them off before entering, Rikyu will make one cast them off (this is the threshold where Zen enters the way of tea). And it is not done by imposing something as a subject. It dissolves in that place, the tea room.

Let me put this in modern terms so that readers can follow. We live in an age where everyone worries excessively about social status. As the meaningless lists in profile columns show, it has become routine to put forward labels and decorations, conceit, pride, arrogance and superiority. The university one came from, graduate school, doctorate, what qualifications one holds, an endless list of what work one did in one's career. With these people did gain social standing, and they could earn. They were converted into social credit, and they won stable careers. But let us calm down and look. The age that has resulted is this ungainly. The stronger one's will to advance into the future, the less one should fall into such folly. People like this will be weeded out sooner or later anyway, so one should be the first to spend years, through one's own discipline, stripping off this outer world of social decoration. It cannot be done in a day. It takes years.

Suppose you were invited to one of Rikyu's tea gatherings. If, until the day you drank his tea, you were still concerned with social decoration as you are now, you would not understand the heart of his tea. If you trained yourself in thorough introspection until that day, and still hit a wall and were fighting an inner battle, Rikyu would quietly lift that shackle through the tea.

Rikyu served tea in an extraordinary, tense silence, in a place where only a little light came in. Rikyu's figure looked vague, indistinct. And so the guests saw themselves reflected clearly. However ugly the self in that mirror, would they accept it, and resolve to set themselves right through discipline? This, in fact, is the essence of the chanoyu that Sen no Rikyu created.

Look again at the characters and you will see that Rikyu did not write the Chinese-style 茶湯. He used the Japanese phrase 茶の湯, with its "no." The heart of Rikyu that chose 茶の湯 over 茶湯, the truth of that profound world, is condensed in this concept.

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 “The tearoom as a mirror”, first written on 19 December 2025. What did Sen no Rikyu actually mean by tea beyond wabi-sabi? Rikyu's tea set a mirror before the guest, Takahiro Mitsui argues, who had to accept the self and resolve to set it right; rigid form missed the point.

Takahiro Mitsui's thesis: asking how a culture comes into being, chanoyu and sado are alike but not the same, and that suspicion is right; the walls people meet in the Way of Tea are the same walls met in the martial and artistic ways (SJ 259).

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 )
