About Iaido and Breathing: excerpts from “The Essence of Budo” by Kawakubo Takiji
Editors note: the following guest post/translation comes from Eric Spinelli based in Tokyo. Although the notes were put together for iai practitioners, the content here is also not only highly applicable for kendo people, but to all practitioners of Japanese martial arts.
About the Author
KAWAKUBO Takiji (1896 – 1985) studied Yamauchi-ha Muso Jikiden Eishin Ryu under SAKAGAMI Kameo, a student of UNO Mataji, in Nagasaki1. He held the rank and title of Iaido Hanshi, 10th dan and Kendo Kyoshi2.
These notes were written as a reference for the members of the Iaido Aikokai3. They cover the important breath control techniques as written in “The Essence of Budo”4 by Prof. Sato Tsuji, (Professor of Literature, Kogakkan University). Breath control has an incredibly deep connection with budo and it is my hope that you will read these notes thoroughly and make use of them in your practice.
-Kawakubo Takiji, Iaido Hanshi, April, 1978
Kokyu-ho (呼吸法, Breathing Techniques)
Iai and breathing techniques have an incredibly deep connection with each other. It is said that, “when exhaling, the body is true; when inhaling, the body is false.5” Obtaining both truth and falsehood within one’s movements is of utmost importance. Practitioners of iai must practice breath control at the same time they practice iai technique.
Correct breathing techniques is tanden breathing. The following is a summary of the important parts of Prof. Sato’s “The Essence of Budo” and should be a reference for all iai practitioners.
By adjusting our breathing, we can tense6 our entire body and move in a fluid and lively manner. It is for this reason that breath control is important for iai.
When the muscles of the lower abdomen are tensed, the seat of body’s power, the tanden, appears. The tanden is the tension of the muscles and appears only in the living body. It was not discovered through western medicine or academics because it cannot be found in a dissected body.
Defined broadly, the tanden is the front of the lower body, the abdominal muscles that can be tensed together. Defined more narrowly, it is where power gathers when the abdominal muscles are tensed.
This point is approximately three centimeters below the navel. The point above this is called the kikai. Inhaled breath fills the the kikai naturally and without effort but when it is exhaled, power is focused on the tanden below it.
The tanden is sometimes called the center of the body, but it is more accurately called the center of gravity. The center of gravity presides over the body, controlling the function and movement of the extremities. It performs all true movement in budo and other arts.
Tanden-sokuho (丹田息法, tanden breath technique）
Breath is what gives life to posture. Correct posture only has meaning when it is based upon correct breathing and correct posture follows naturally from correct breathing.
Let’s examine the human body’s breath. When sleeping lying down, the breath naturally enters the body, expanding the chest and upper abdomen. As the breath is exhaled, those parts become empty. Both the inhalation and exhalation happen only in the upper body; the lower body does not participate. However, if the tanden is actualized when the body is upright and the hips are bearing the weight of the body, breathing can be done through the tensing and relaxing of the tanden. When the tanden relaxes, air naturally is pulled into the center of the body. When the tanden tenses, this air is expelled from the center of the body8. If the breath does not pass through the center of the body, but only the upper body, the breath is the same as a sick or feeble person.
How to Breathe Deeply
Laughter demonstrates natural deep breathing, with the breath passing through the center of the body. Consider the human lungs as a single vessel. When the chest is used in unfocused breathing, only twenty or thirty percent of the vessel is filled. Try emptying the chest, keeping the body straight and exhaling until you feel the chest muscles relax. Because there is still a lot of air left in the body, try laughing. When you do so, you should feel a comfortable strength naturally filling a single point in the lower abdomen. The seat of this power is the tanden.
The tanden is described as three centimeters or 1.5sun below the navel but, in reality, it should not be defined from the outside of the body. Rather the tanden is the point you felt fill with strength when you laughed with an empty chest. Laughter is a sign of health. Humans laugh often when healthy and by purposely laughing more one’s health naturally improves.
Laughter occurs as convulsions. Let us examine this process. First, one fills the lower abdomen with strength, pushing the air out. Next, the strength in the abdomen lessens, pulling new air down into the bottom of the lungs. The air flows in in an instant but in that short time the vessel is almost completely refilled. Laughter is an efficient form of deep breathing. Breathing as if one is laughing, without convulsions, calmly and without pause, is tanden-soku (alternatively, tanden-kokyu). It is a form of deep breathing using the lower abdomen to exhale. It is the genuine kokyu-ho of zazen and seiza9, as well as all varieties of budo and other arts.
While standing upright, you must always extend the lower back and fill the lower abdomen with strength. At the same time you must keep tension in your center, specifically the lower abdomen, and quietly breath out. Keeping twenty or thirty percent of the air in your lungs, you should relax the lower abdomen. Because there is always an atmospheric pressure around you, air will flow into you naturally just as if you had loosened your grip on the bulb of a dropper10. This happens in an instant but, as mentioned above, an incredibly large amount of air is inhaled.
On a slightly different topic, it is necessary to always keep the external sphincter muscle of the anus contracted. In kyudo they teach, “keep your hole closed.” However, focusing on the anus is an uncomfortable, animalistic feeling. Instead you should put strength into the lower abdomen and the sphincter will contract proportionally and unconsciously.
Laughter is an action of exhalation but humans can discover the location of the tanden through the action of inhalation as well. Try swallowing your saliva. When you do your muscles contract towards your navel but, immediately after the saliva enters the stomach, the lower abdominal muscles clench tight, stopping the saliva there. The place where these muscles contract is the tanden11.
Exhalation is Truth, Inhalation is Falsehood
All true human action is performed while exhaling. The exhaled breath is the breath of a human realizing an action and when breathing out one is in an active kamae. In budo and other arts, exhalation is truth, inhalation is falsehood. A human’s upright body is a body in action and, while awake, exhalation should be the principle form of breathing. Inhalation is a natural, unconscious state. It is a principle of budo that the change from stillness to action must start by breathing in and the principle movement must be brought to a finish while breathing out.
It is desirable to exhale for as long as possible. Breathing shallow breaths without strength in the hara, it is normal to take 17 or 18 breaths in one minute. The hurried breaths of a sick man are countless. When correct tanden breathing is practiced, one will take only seven or eight breaths in a minute, dropping to four or five with mastery. In zazen or budo, a person who has achieved complete harmony in his body will number one or two breaths per minute, or even less. It is said that in the Edo period, a famous spearman once walked the length of Ryogoku Bridge12 with just one breath.
One must not strain when breathing. In correct breathing there is no stopping or holding of the breath. The breath must flow out naturally. With the lungs full to the bottom from correct breathing there is more air available than one might imagine and even a big, unwavering exhalation will continue for a long time.
Each of us can discover whether our exhalation is correct and the entire body is in harmony or if our exhalation is in discord and out of harmony. The first step is to focusing our awareness inward. If there is no stiffness or strain in the body when breathing out, the nasal passage opens and an indescribable, pleasant strength fills the lower abdomen. The second step is to feel the breath with the palm of the hand. Correct breath comes out warm and gently. Discordant breath comes out cold and rough. In the past, practitioners of budo and zazen would place a candle in front of the nose and practiced tanden breathing so that the flame would not flicker.
When the method of correct breathing is mastered, neither the breath in nor the breath out should be able to be felt. There should be only the tension and relaxation of breathing in and out. If the breath can be felt or heard, there is still some stiffness or strain in the body (for example, the chin muscles or oral cavity).
In contrast to the tension of exhalation, inhalation is a relaxation and should be done in the shortest possible amount of time. This relaxation, however, must not be a complete relaxation but a relaxation supported by tension.
The act of exhalation starts from the natural state of inhalation. Inhalation, however, is the opposite; it is born from a state of human effort and the tension of exhalation. It starts with the lower back extended and strength filling the lower abdomen and the relaxing of that tension, but without releasing all of the strength. To understand this method it may help to consider how one breathes while sprinting. It is necessary to put strength into the lower abdomen to run but breathing in can only be done by slightly relaxing that tension.
The Principles of Breathing
Having understood the correctness of and realizing the depth of logic of tanden breathing, let us now provide some additional support.
Even in the middle of physical exertion budo masters do not become short of breath nor does their breathing become rough. This is because the muscles throughout their entire body are settled in the correct position and because they regulate their diaphragm correctly.
The Japanese term for the diaphragm is oukakumaku (横隔膜, horizontal separating membrane). It gets its name from the fact that it separates the chest and abdominal cavities. It is called a membrane but it is actually a thick, membrane-like layer of muscle. It is the only voluntary muscle among the internal organs and can be tensed at will. Those who aim to master correct breathing must first start by training the diaphragm. To do so, practice allowing the upper abdomen (solar plexus) to draw in as you exhale. It may help to place the hand on the solar plexus to feel the movement of the diaphragm.
If, as you breathe out, you tense the lower abdomen and relax the upper abdomen (solar plexus13), the lower abdomen will become round like a rubber ball. As the solar plexus depresses the navel will point upwards. As you continue to breathe in and out, this round shape should not change but as you breathe out it should become harder.
When breathing using the tanden, the diaphragm should first move down as you breathe in and the ribcage should rise as air enters the body. Next, as you breathe out, the ribs should lower as the diaphragm rises, pushing the air out of the lungs.
The Solar Plexus14 (Strengthening Character and Moral Sense)
Directly below the diaphragm in the abdominal cavity is the solar plexus nerve complex. his is a group of autonomic nerves the size of the thumb that receives instructions from the diencephalon15 to regulate the body. The solar plexus is such an important organ that, it is said that if the brain is the seat of knowledge, the solar plexus is the seat of moral sense.
Tanden breathing stimulates and trains the solar plexus, calming the nerves, and works to strengthen the character. This is one reason that budo and zazen aid in a person’s moral education.
In addition to the very real effects on efficiency of movement, as discussed above, focusing the whole body’s strength in the tanden invites a spiritual benefit as well.
The diaphragm is shaped like an arched ceiling. When one has put no strength in the abdomen and is, for example, surprised, the diaphragm contracts towards the chest cavity and presses up against the heart, pushing the apex of the heart against the chest wall causing the heart to beat faster. If the diaphragm can move up and down in a controlled manner the base of the heart can expand and the heart can pump slowly. This reduces mental states such as anxiety, surprise, and fear. It is important to note that a calm and composed mental state is not achieved by the mind alone, but by correct posture and correct breathing. It must be build on the strong foundation of the physical body.
The Second Heart
Some call the diaphragm the second heart. The heart in the chest pumps blood through the arteries but the contractions of the diaphragm are incredibly important in returning the blood from the veins of the lower body to the heart.
Normal breathing is a matter of controlling the lungs. As you inhale the chest expands and the upper abdomen inflates. As you exhale, the chest becomes empty and the upper abdomen collapses in. The lower abdomen is not involved at all. This is true of shallow breathing and surely also when sleeping laying down.
As mentioned above, when one wakes and stands upright, allowing tension to keep the body balanced, the tanden appears as the seat of the whole body’s strength. Because all true movement, without exception, must be generated from the tanden, the breath too must originate from the tanden.
Breathing from the chest and breathing from the tanden are completely the same. Breathing from the tanden, however, is incomparable with natural breathing in the amount of air that fills the lungs.
Tanden breathing is neither unnatural breathing nor reverse breathing. Rather, it follows natural breathing and takes the same form, but is one level higher and more efficient. It is the absolute correct way to breathe.
Because tanden breathing does not go against the natural order of breathing, with the exception of sleeping, it should be possible to do all day without issue. It is in fact the best thing you can do for your health.
The function of breathing is to absorb oxygen from the air and expel the carbon dioxide gas generated inside the body. If one’s breathing is shallow, the oxygen in the blood decreases and, carbon dioxide combines chemically with water and builds up inside the body, decreasing the life force of the body’s cells.
Focus on Breathing Out
Normal air is made up of over twenty percent oxygen and the air humans exhale is approximately sixteen percent oxygen. Our bodies absorb the four percent difference. The air we exhale, however, contains over 100% more carbon dioxide than normal air (0.04% in air and 4.4% in exhaled breath). We can induce from this that if we breathe a large amount of air into the lungs, as long as we are exhaling, the body continues to absorb oxygen. We should thus focus only on exhaling and expelling carbon dioxide. In budo and zazen it is unnecessary to think about inhalation and important to focus instead on our exhalation.
The Importance of Deep Breathing
The lungs are made up of millions of microscopic alveoli. The inner surface of the lung that makes contact with air is 56m2, twenty-five times greater than the outer surface area of the body. This is half the size of a tennis court. The greater portion of alveoli are unused in normal, shallow breathing and remain unexposed to fresh air. This is why it is important to breath deeply.
Deep breathing consists of an inhalation component and an exhalation component. A naturally occurring inhalation component of deep breathing is yawning. When yawning the lungs fill completely and there is a feeling of the kikai (below the navel) filling as well. Professor Sato gives this type of breathing the name kikai-soku16. Inducing yawns throughout the day, inhaling deeply into the lower abdomen and stretching the body, has health benefits.
Likewise, a naturally occurring exhalation component of deep breathing is laughter. Here air is pushed out by tension of the tanden, the point below the kikai. When the tanden relaxes, air is sucked in. This is called tanden-soku. It is the breath of budo, zazen, and seiza17. Tanden-soku is the same deep breathing as laughter but steady, without the convulsions.

Chris, I think that a common confusion is between qi as “breath” and qi as used as an adjunct to strength, jin, etc. I see similar confusions a lot, where “Shin” (“Xin”), and words that were euphemistically used to refer to jin are translated literally. I think the above article was pretty good, all things considered, but there are probably some confusions in it, also.
It seems whomever you were replying to has unfortunately deleted their comment but please allow me to use your comment as a springboard to make a general clarification to all readers about this piece. I am not familiar with all of the Chinese terms you used, but Kawakubo never uses the word ‘ki’ (気, Chinese: qi) in the source text. The character appears only in compounds, many related to breath, such as ‘koki’ (呼気, exhalation), ‘kyuuki’ (吸気, inhalation), and ‘kisoku’ (気息, breath). While ‘ki’ seems quite intertwined with breathing and tanden, in this piece Kawakubo – and possibly Sato as well – explains himself using only the concepts of breath, tension and relaxation, and strength. Of course, discussion related to ‘ki’ is welcome but I ask that people also note the language the author used (or did not use) here.
Also, Mike, if you could highlight and elaborate on any possible confusions, I would appreciate it. I consider myself a novice in these topics and translated this piece not only because the source is quite rare but for my own edification, as one step in my studies. I do not take nor intend to present this text as the end-all, be-all on the topic. Your and anybody else’s insights are greatly appreciated.
Thank you Eric for translating this insight on the effects of breathing and the martial arts. Look forward to future contributions.
Sorry … I was just back from a trip last night and rushing through various and sundry communications. Chris pointed to your article and I mistakenly took the comments board to be associated with him.
The article appears to be a fairly general (not specific as to details) treatment of dantian breathing. The more common terms instead of “truth” and “falsehood” would be “substantial” and “insubstantial”, IMO. The inhale (“In”, “Heng”, “Un”) is the storage of elastic power and pressure; The exhale (“Yo”, “Ha”, “A”) is the release of power. The Tanden/Dantian is the place where the breath is ‘changed’ to power; hence it is the area of change. Unless the tanden is connected to the rest of the body (something developed through training), the power of the tanden is limited, though.
Within the pressurized body there are two weak areas (think of the body as being a balloon): the anus and the mouth. Keeping the anus closed is an aid to building up pressure within the lower tanden and keeping the superficial connectedness of the body whole. Keeping the mouth closed with the tip of the tongue on the upper palate similarly helps make the superficial connectedness of the face whole.
Anyway, good article. Thanks for translating it.
Thanks for the follow up. To be honest, the line about substantial vs insubstantial was one of the hardest parts to translate so I cheated and threw both definitions in the footnotes. That’s why I keep my day job!
Your points seem mostly consistent with what I’ve read and been taught. I haven’t learned much in reference to the mouth, other than to avoid tension in the jaw. One thing that I believe I was told when I tried out a pranayama class, was to keep the tongue slack and away from the roof of the mouth. I’m curious to hear you say the opposite, at least in terms of positioning, but it’s intriguing to say the least, especially when you describe it as a “superficial” connection. The journey continues.
I have been involved in a group for a number of years that focuses on kokyu a lot, with emphasis on the kikai-tanden. I have no idea about Chinese martial arts take on the situation, but I think this article is fairly thorough regarding the general Japanese attitude to kokyu-ho.
However, saying that – and my sensei is very clear on this point – verbal description of the process and actual experience is impossible. I don’t think there is any “confusion” in what’s written here at all – it’s just someones description of their experience… which is almost certainly different from another persons. In that way it’s a valuable piece.
Eric, “kokyu” implies the use of jin-forces augmented by breath-conditioning, although of course all jin-forces are supplemented by breath conditioning, so the emphasis on inhale-exhale (think “In-Yo”, “A-Un”, Heng-Ha, etc.) in ‘kokyu’ is slightly redundant. Using the kokyu forces implies that the body elasticity is being developed and that elasticity yields some very sudden releases of forces … which is what the “lightning draw” of iaido should lead toward. China similarly had a lot of lightning-draw exponents. Does a focus on breathing, tanden, etc., lead to the lightning-draw capabilities (and other martial applications)? Of course.
Yes…thank you Eric for this translation…and also thanks and appreciation to George and Mike for their comments. I am very happy to read this discussion! I found this excerpt to be excellent. It gave some very vivid descriptions that helped me with further insight. Are there any books by Kawakubo Takiji that have been fully translated? Also if anyone could suggest additional reading on breathing that would be very much appreciated.
George McCall wrote: “I have no idea about Chinese martial arts take on the situation, but I think this article is fairly thorough regarding the general Japanese attitude to kokyu-ho.”
George, the Japanese attitude toward kokyu usage always borrows from the Chinese classical perspective and cosmology. The classical sayings are fairly precise (even though ambiguously translated by most westerners and some Asians) and the whole idea of tanden, breath, In-Yo, etc., is pretty much set in stone. In other words, the Chinese perspective and the ‘Japanese attitude’ are technically the same (allowing for the missteps and mis-translations that naturally arise), so there is no Japanese way and Chinese way … the body only works in one way.
The body may perhaps only work in one way, but interpretations are myriad. Even an individual attempting to describe something mechanical like how to move the legs or arms in say (because this is a kendo site) a men strike we will see differences when compared to others descriptions… sometimes even contradictory interpretations. And this is a relatively simple movement.
When we talk about internal energy or something more “mysterious” as ki then I think there can be no definitive description.
My sensei tells me straight that he can point out what to do, but it’s up to me to work out how to do it. The result is of course a deeply personal one and cannot be measured by others.
I grant that there are myriad interpretations, for a variety of reasons, but there is still just one way the body works in the Asian system involving Tanden, kokyu, breath, Yin-Yang, etc. By dint of the fact that some of those terms are being used in the translated article, there is one type of body movement being discussed. Does everyone reading the article understand the topic or do things in the proscribed (in the Chinese classics) way? No, but that doesn’t mean there are a number of valid interpretations; it just means that not everyone has gathered the knowledge and skills to use kokyu, breath training, hara to manipulate the body, and so on.
Kendo uses or should use this same method of movement. There may be different interpretations and many things get lost within various styles/schools, but this basic way of moving is used in all the Asian martial-arts that I’m aware of.
Anyway, I can’t see how the conversation gets more productive at this point. Thank you for the translation, Eric.
I’m glad you enjoyed it. Kawakubo Takiji wrote a book titled “Muso Jikiden Eishin Ryu Iaido no Tebiki” (A Guide to MJER Iaido, Kohyohsha 1971) but to the best of my knowledge it was never translated and is out of print. The writings I’m working from here are a collection of handwritten notes written for members of the Kodaira City Iaido Aikokai dojo in Tokyo Prefecture. I doubt they have ever been published in any language, which is part of my interest in translating them to English. Unfortunately I do not have enough of a background in Buddhism to make sense of a number of the other articles, but as I continue my own studies I may be able to share bits and pieces.
Considering how it started and that here was no real 2-way discussion anyway, I’m not sure it was that productive in the first place.
Thank you very much Eric…I would be interested in any further translations you complete.
and thank you George…I find ALL this discussion productive
I posted a translation into spanish of the text in my blog
Andrés, we usually ask that you contact the author first *before* using their work on different sites. Personally (I’m not the author), I would warn and dissuade anyone making translations into a 3rd language of already translated material (and if you do so anyway, provide proper disclaimers).
To all Sensei. My name is Graham Dixon from Brisbane Australia. All the Martial Arts have my fullest attention. On the issue of ‘breathing & mind control’ I strongly. believe that these qualities could/would of immense benefit to Western sufferers, diagnosed with ‘Depression and Anorexia’ as from my observations appear to me as ‘self-inflicted’ and a lack of ‘self-control’. I am respectfully yours. G. Dixon. Thank-you.
Thank you very much for the translation of the article which contains all the very true thoughts of Sato Tsuji and which I know since 40 years from the book “HARA”, written by Karlfried Graf Dürckheim. The text of Sato Tsuji was extremely important for me because in all the years I found out, that most people in various Zen-groups here in Germany in fact have no idea of Tanden und the right way of breathing.
So one can hear or read very often: “Breathe in very deep and slowly into your abdomen…” – but they only mean the upper ubdomen because they have no idea of the deeper abdomen and the tanden and that the tanden becomes most powerfull at the end of the exhaling. The result is that most people who try to practice Zen stop with it because it does not have any advantages for them.
But I gave it up to talk about tanden to other people because people would play with it – and then start a totally new method of any yoga or so. Many people are so impatiant and want to have the benefits of a method from one day to the other. — But for me tanden is a “holy secret” and I don´t like to talk about “my secret” too often. Do you understand what I mean? – Katsuki Sekida (Zen Training) says that also many monks in japanese monesteries do not know the right way of breathing with tanden….
I want to thank you very much for the article above
