He was born in Ueno, a district of Tōkyō, in September 1911. It all began at the age of three or four when he was surprised to find that he had relieved someone’s toothache simply by placing his hands on them. He was a child, and his hands moved toward the target without him realising what he was doing. He accomplished his first feat at the age of twelve, when he cured his neighbours who were suffering from dysentery after the great earthquake that struck the Tōkyō area in 1923. From that age on, he began to receive people who asked him to heal them. At the time, he had no knowledge, not even basic knowledge, of anatomy or medicine. As a teenager, he began to realise the consequences of his actions. At first, like almost all healers, he believed that he had an exceptional power that only he possessed. He found his calling but did not stop there; he continued on. He taught himself all Eastern and Western therapeutic methods. At the age of fifteen, he opened a dojo in Iriya. At seventeen, he formulated Precepts of Full Life (Zensei Kun), which provide a better understanding of his thinking. In 1930, he wrote Reflections on Integral Life, a surprising text for a young man who was only nineteen at the time.

Seitai: a global view


A dream
Health has become a technological dream. From the 19th century concept, summarized so well by Jules Romain in his play Knock, according to which every healthy person is considered as a person unaware that they are sick, we have shifted into the 20th century concept which claimed it would eradicate diseases thanks to pharmaceutical chemistry and rays. As for the 21st century, it proposes to solve all problems with genetics or transhumanism.The analysis claims to become more and more thorough, we have shifted from dissection to sequencing. By cutting up the human being into increasingly smaller pieces, down to cells and now genes and even smaller, we are losing sight of the whole, we are moving away from the notion of the individual (from the Latin individuum: what is indivisible) and, as a curious consequence, we are compelled to treat the human being in general and no longer in particular. The human being appears like a collection of parts. Each part of the body has its own specialist, including the psyche of course, and all these specialists take care of their clients’ symptoms. For ideological or even religious reasons, when the expected result is lacking with classical medicine, we turn to what are called alternative medicines. These can be ancestral methods of great value as well as small fiddles. We can find around us lots of recipes promulgated on the internet, and forwarded by our friends and acquaintances, each thinking they have the solution to all our problems of health, energy, or simply to an ordinary disorder.
The symptom
We persist in removing the symptom, because it is the symptom that disturbs us. Of course, we cannot deny its importance, it is the sign, often the indicator, of a problem that had not yet been perceived. But it is also and above all the expression of the work done by our organism to solve this difficulty. Often, body problems are misunderstood and we want to solve them as fast as possible without really seeking the root cause. We need only make the symptom disappear to satisfy everyone, to think we are cured, even though most of the time we have simply put the problem aside and, even sometimes, prevented the body from reacting.
The body has its reasons that reason does not know

To live Seitai
According to Noguchi Sensei, beginning to take care of children at birth was already late. The months of pregnancy, the delivery, the first cares given to the baby were fully part of his concern about the childs future life as well. In his books, Tsuda Itsuo Sensei provides us with many indications about pregnancy, delivery, breastfeeding, nutrition, weaning, first steps, etc., particularly in volume four entitled One. Seitai does not set rules to be followed in every occurrence, it is not about figuring out the right solution to the problems of early childhood, childhood, or adolescence, as in childcare or pedagogy books. Seitai deals with the manifestations of life with no preconception, it here again makes it possible to guide parents while, at the same time, enabling them to develop their intuition thanks to a dialogue in silence with the baby and later with the small child. For those who have not had the chance or sometimes the possibility to let their body work according to their own needs, are there still possibilities to retrieve a healthy state? This is where the practice of Katsugen Undo comes in.
The notion of individual in Seitai
For Noguchi H. Sensei, there is no human being divided into parts but always a single body.In the light of the most recent discoveries, one becomes aware, for instance through the fascias theory, of the interaction between the various parts of the body, even when sometimes extremely far from one another. Some of these theories made possible to rehabilitate ancestral techniques from distant countries, which had not so far been understood in their depth and had very often got little respect from Western medical science. Other discoveries, mentioned particularly by M.-A. Selosse in his book Never Alone,11 have emphasized the symbiotic dimension of the individual, the interaction that takes place between bacteria and the body: the human being is no longer considered separate, modern biology gets obvious insight on his nature as a symbiont. Once more once again should I say , one is compelled to consider the whole of the individual.However, in spite of experiencing a time when technologico-scientific discoveries have considerably increased knowledge about human beings, there is little change from the Seitai perspective, they remain the same as sixty or seventy years ago; the causes disturbing them, disturbing their Kokoro are different but human beings themselves have remained the same. Unfortunately, it can be seen that many bodies and minds are more fragile today, when ideologies about health have designed individuals deeply dependent on all kinds of specialists, thus generating a certain type of alienation which might be difficult to understand or analyze by anyone lacking an overview of society. The abyss to the bottom of which we are heading calls for a recovery of everyone at the individual level and this is perhaps where the Seitai orientation may enlighten us: by providing the individual with a unique tool in order to recover their autonomy, to re-appropriate their own life and live it fully. That is why the practice of Katsugen Undo and Yuki are the two activities proposed by the Itsuo Tsuda School for they are the Alpha and Omega of the practice of Seitai.

Seitai
The Seitai principles, which could even be described as “Seitai philosophy” – a way of seeing and thinking about the world – were developed by Haruchika Noguchi (1911-1976) in the first half of the twentieth century. In brief (!), Seitai is a “method” or a “philosophy” that includes Seitai sōhō, Taisōs, Katsugen undō, Katsugen sōhō, and Yukihō. These are practices that complement, permeate each other, and form the breadth of Haruchika Noguchi’s Seitai thinking. We can also mention the study of Taihekis (postural tendencies), the use of the hot bath, the education of the subconscious, the importance of birth, illness and death…
An art of living from beginning to end.
Today, unfortunately, the term “Seitai” is overused and means anything and everything. Some manual therapy practitioners too easily lay claim to Seitai (Itsuo Tsuda would say it takes twenty years to train a Seitai sōhō technician!). As for the charlatans who offer to transform you in a few sessions…, let’s not talk about it! The magnitude of the art of living, the global understanding of the human being in Seitai seem far away. If all there is left is a technique to be applied to patients, the essence is lost. If all there is left of Katsugen undō is a moment to “recharge your batteries”, the essence is lost.
Haruchika Noguchi and Itsuo Tsuda both went much further than that in their understanding of the human being. And the seeds they sowed, the clues they left for humans to evolve are important. Can we then speak of a way, of Seitai-dō (道 dō/tao)? Because that is a radical change of perspective, an upheaval, a totally different horizon opening up.
Let us go back in history…
The meeting with Haruchika Noguchi: the individual as a whole
Itsuo Tsuda met Haruchika Noguchi around 1950. The approach to the human being as proposed in Seitai interested him from the very beginning. The sharp observation of individuals taken in their indivisible entirety/complexity, which Itsuo Tsuda found in Noguchi, was an extension of what had already captured his interest during his studies in France with Marcel Mauss (anthropologist) and Marcel Granet (sinologist). Itsuo Tsuda then began to follow Noguchi’s teaching and continued for more than twenty years. He had the sixth dan of Seitai.
‘Master Noguchi enabled me to see things in a very concrete way. Through the things manifested by each individual, it is possible to see what is going on inside. It is completely different from the analytical approach, in which the head, the heart, the digestive organs each have their own specialization; and there’s the body on one hand and the psyche on the other, isn’t that so? Well, he made it possible to see the human being, that is, the concrete individual, in its totality.’ 1Itsuo Tsuda, Interviews on France Culture radio, “Master Tsuda explains the Regenerating Movement”, Broadcast N° 3, early 1980s (Heart of Pure Sky, 2025, Yume Editions (Paris), p. 23 (1st ed. in French, 2014, p. 24))
Illness as a balance factor
All the more as it was precisely in the 1950s that Haruchika Noguchi, who had very early discovered his capacity as a healer, decided to give up therapeutics. He then created the concept of Seitai, i. e. “normalized terrain”.
‘the word “terrain” referring to the whole that makes up the individual, the psychic and the physical, whereas in the West we always divide things into psychic and then physical.’2Itsuo Tsuda, ibid., Broadcast N° 4, p. 28 (1st ed. p. 29)
The change of perspective with regard to illness was crucial in this reorientation of Noguchi.
If the terrain is normalised, illness disappears of its own accord. And moreover, one becomes more vigorous than before. Farewell to therapeutics. The fight against illness is over.’3Itsuo Tsuda, The Dialogue of Silence, Chap. IX, 2018, Yume Editions (Paris), p. 75–76 (1st ed. in French, 1979)

A path towards autonomy
Abandoning therapy also goes hand in hand with the desire to get out of the dependence relation that binds the patient to the therapist. Noguchi wanted to allow individuals to become aware of their ignored capacities, he wished to awaken them to the fulfilment of their own being. During the twenty years they followed each other, the two men spent long moments talking about philosophy, art, etc., and Noguchi found in Tsuda‘s vast intellectual culture the substance to nourish and expand his observations and personal reflections. Thus a relation which was enriching for both developed between them.
Itsuo Tsuda was the editor of the magazine Zensei, published by the Seitai Institute, and he actively participated in the studies led by Noguchi on Taihekis (postural tendencies). A text by Haruchika Noguchi published in the magazine Zensei of January 1978 reveals that it was Itsuo Tsuda who advanced the hypothesis – validated by Noguchi – that type nine (closed basin) would be the archetype of the primitive being.4About Taihekis, consult Itsuo Tsuda, The Non-Doing, 2014, Yume Editions (Paris) (1st ed. in French, 1973)
The development of Katsugen undō (Regenerating Movement) by Noguchi particularly interested Itsuo Tsuda, who immediately understood the importance of this tool, especially as regards to the possibility it gives to individuals to regain their autonomy, without needing to depend any more on any specialist. While recognizing and admiring the precision and the deep capacity of the Seitai technique, Tsuda considered that the spreading of Katsugen undō was more important than the teaching of the technique. He therefore initiated groups of Regenerating Movement (Katsugen Kai) in a great many places in Japan.

Itsuo Tsuda favoured the spread of Katsugen undō in Europe as a gateway to Seitai.
Today, even in Japan, Seitai sōhō has taken an orientation that brings it closer to therapy. One problem: one technique to apply. Katsugen undō becomes a kind of “light” gymnastics for well-being and relaxation. This is far from the awakening of the living, of the autonomous capacity of the body to react that Haruchika Noguchi‘s Seitai is meant to be.
The yuki exercise, which is the alpha and omega of Seitai, is practised at every Katsugen undō session. Thus, although Tsuda did not teach the technique of Seitai sōhō, he transmitted its essence, the simplest act, this “non-technique” that yuki is. The one that serves us every day, the one that gradually sensitizes the hands, the body. This physical sensation, that is real, that can be experienced by all, is today too often considered a special technique, reserved for an elite. We forget that it is a human and instinctive act. The practice of mutual Katsugen undō (with a partner) is also getting lost, even in the groups that followed Tsuda‘s teaching. What a pity! Because through yuki and mutual Katsugen undō, the body rediscovers sensations, those that do not go through mental analysis. This dialogue in silence, which makes us discover the other from the inside and which therefore brings us back to ourselves, to our inner being. Yuki and Katsugen undō are for us essential tools, recommended by Haruchika Noguchi, on the path towards normal terrain.
But time goes by and things get distorted, like words of wisdom of some people become religious oppressions… Little by little Katsugen undō is nothing more than a moment to “recharge”, relax and above all not change anything in one’s life, in one’s stability. Seitai, a method to lose weight after childbirth… While it is a life orientation, a global thinking. The huge step Haruchika Noguchi took in moving away from the idea of therapeutics is a major advance in the history of mankind. His global understanding of the individual, the sensitivity to ki, sufficiently recovering sensitivity and a center in oneself from where to listen to one’s own body and act freely.
It is not even about opposing methods, theories or civilizations. It is purely and simply about the evolution of humanity.

Some additional information
Seitai was developed by Haruchika Noguchi (1911-1976) in Japan. Katsugen Undo (or Regenerating Movement) is an exercise of the extrapyramidal motor system that is part of Seitai. Itsuo Tsuda (1914-1984), who introduced Katsugen Undo to Europe in the 1970s, said: ‘The human body has a natural ability to readjust its condition. This ability […] is part of the extrapyramidal motor system.’
Excerpts from the video on Yuki
There is natural Yuki, when you have a headache, you put your hand on your head. If you have a very bad headache, you put both hands on your head. But not everyone puts their hands there, precisely. Some people put their hands like this, some put them like that, and that’s natural Yuki. That’s precisely why you can’t teach Yuki. You can’t say, “If you have a headache, put your hands like this and do Yuki, circulate the ki.” “Oh yes, but that doesn’t work for me.” — Oh yes, yes, that’s the technique. — When I have a headache, I do it like this — And I do it like this — And I do it like this, there, that feels good.”
Yuki’s exercise is a specific moment. We do it during Katsugen Undo sessions. At a certain point during the session, there is Yuki. So first we bow to each other. The bowing between two people is the coordination of breathing. Then, one of the two turns their left side toward the other. One hand behind, you see, at eye level, and one hand in front. Then the person lies down, we put our hands on their back and circulate the ki. In this case, it is the exercise to rediscover Yuki. During the movement sessions, it lasts 5 minutes, up to maybe 8 minutes. We all do it together. It is both an exercise that allows us to become aware of ourselves and to make the other person aware. It is not learning, it is discovery. We discover and we deepen our understanding.
Yuki is circulating ki. But ki has no form. Well, here it takes on a form. Ki has no form, ki is atmosphere… the concept of ki is very vague. But here, because there is an action, it has a form. Some people want to associate it with energy, we talk about vital energy. I don’t really like that. I don’t really like that term. “Energy” immediately makes us think of electricity, etc. Or psychic energy that bursts forth, etc. And that’s not what this is about.
Yuki is an experience. It is first and foremost an experience.
he first time I encountered Yuki was because — I remember we were at a café with my master Itsuo Tsuda. It was in the early 1970s, and during a conversation, he simply placed his hand on my back and said, “Yuki is this.” That changed everything.’

Hello Illness #1
Interview of Régis Soavi about Katsugen Undo (or Regenerating Movement), a practice made by Haruchika Noguchi and spread in Europe by Itsuo Tsuda: article by Monica Rossi “Arti d’Oriente” (#4 / may 2000).
“After reading the books of Itsuo Tsuda ( 1914-1984 ), I was fascinated by his arguments, which range freely from the subject of Aïkido to that of children and the way they are born, illness, or his memories of Ueshiba Morihei and Noguchi Haruchika, and I wanted to know more. I continued to have a sensation of something beyond my understanding.
So I began to ask, what exactly is this Regenerating Movement (Katsugen Undo ) that Tsuda spoke of, a spontaneous movement of the body that seemed able to rebalance it without needing to intoxicate it with medication ; an ancient concept but still revolutionary, above all in our society. I was unable to get any satisfactory answers to my questions : those who have practiced the Regenerating Movement couldn’t describe it or explain ; the answer was always : “You should try it yourself in order to understand ; the first time, it will probably unsettle you a bit.” So I decided to try it. In Milan, the school that refers to the teachings of Itsuo Tsuda is the “Scuola della Respirazione”. There, one can practice Aïkido and the Regenerating Movement ( in separate sessions ). But, in order to go to the sessions of Movement, one must first participate in a week-end course conducted by Régis Soavi, who has continued the work of Tsuda in Europe.

Kokoro
A text by Haruchika Noguchi, founder of Seitai.
‘The kokoro that resides deep within man, has invaluable faculties; its possibilities are so endless and inexhaustible that even if we put together all the ki and we make it concentrated we will never end being incapable or helpless. Everything begins to change, not just the body, when the ki focuses and concentrates in the kokoro. Those who practice it told me after the changes experienced.

Many associate the word kokoro to willpower, but it in fact it does not have its own virtue; on the other hand, instead of pretending to achieve something by willpower force if we simply visualize that we are going to get there, our wish comes true. Anyone knowing how to use his kokoro will see the realization of his wishes.
Since the dawn of time up to now, human being has invented countless things. Here is a table. It has not been around forever, it was created by the use of visualization. Visualization always precedes what will then exist; the word comes just after. If we proceed in this order, step by step, without deviation and with firmness, our wish will be fulfilled. Only then the various worlds in which humanity evolves will widen further. Mankind is like that.Read more
At the philosopher of Ki #2
Continuation and end of the article published in the journal “Question de” in 1975, written by Claudine Brelet (anthropologist, international expert and woman of French letters) and student of Itsuo Tsuda.Part #2
Can one ‘fusion’ respiration and visualization?– Indeed, visualization is one of the aspects of ki. Visualization plays an important and vital role in aikido. It is a mental act that produces physical effects. Visualization is part of the aspect of ‘attention’ of ki. When attention is localized, for example it stops at the wrist, breathing becomes shallow, disrupted… we forget the rest of the body.Read more
