I am going to call the art by the name it gives itself: Mugei-Mumei no Jitsu - “No Name, No Art.” I am not calling it “Ashida Kim style,” because that sounds like something invented by people who need every living thing pinned to a corkboard with a label underneath it. I would rather begin where the material itself begins. Ashida Kim’s own writing describes Mugei-Mumei no Jitsu as a 21st-century martial art and explains the name as “No Name, No Art,” while Dojo Press presents Mugei-Mumei no Jitsu under that same name and calls it “The 21st Century Martial Art.” That matters to me, because names are not decorations in martial arts. A name tells you what a system thinks it is, what it wants to protect, and sometimes what it refuses to become. In this case, the name is already half the philosophy. It is a sly little refusal. No Name. No Art. Very convenient for people who hate tidy boxes, and deeply annoying for people who live inside them with a clipboard and a permanently raised eyebrow.
I have always found martial arts conversations funny in the dark way only martial arts conversations can be funny. Someone says “tradition,” someone else says “effectiveness,” a third person appears from a cloud of internet dust to demand lineage documents, and before long everybody is arguing as if history itself can be settled by the loudest man with a profile picture from 2009. I am not doing that here. I am more interested in what Mugei-Mumei no Jitsu is trying to do. Not what people want it to be. Not what opponents of anything unusual would prefer to mock. Not what romantic believers want to polish until it shines like temple brass. I want the thing itself, as far as I can read it from Ashida Kim’s own writings, Dojo Press material, historical context, and the broader question of ninjutsu as strategy rather than simply fighting in matching pyjamas under fluorescent lights. And yes, I know, “matching pyjamas” is cheeky. I have worn them too. Nobody is safe.
When I look at the historical background, I do not start with Hollywood rooftops, smoke bombs, and a man in black landing silently behind a guard who should probably have looked at the payroll and chosen another profession. I start with historical ninjutsu as intelligence, survival, deception, timing, and indirect action. The Iga-ryu Ninja Museum describes ninjutsu as using psychology, strategy, knowledge for living, and espionage or intelligence gathering, while also making the very useful point that the sword-swinging ninja image belongs more to comics and films than to the whole historical picture. That is a wonderful correction, because it drags the conversation out of costume fantasy and puts it back into human reality. Real stealth is not glamorous. It is patient, observant, quiet, and practical. In other words, it is everything social media is not.
That historical distinction is one reason Mugei-Mumei no Jitsu interests me. I do not read it as a tournament art that accidentally wandered into a smoke-filled room and came out wearing a hood. I read it as an art built around refusing the obvious contest. It is not obsessed with standing still and proving one’s courage by absorbing damage, which is a very romantic way of describing poor decision-making. It is concerned with escape, concealment, misdirection, self-command, sudden decisiveness, and the psychological collapse of the other person’s certainty. The Iga-ryu Ninja Museum’s explanation of invisibility is especially useful here, because it says ninja were not literally becoming invisible; they were using the human gaze, psychology, and gaps in perception to disappear from attention. That sounds less like magic, perhaps, but it is far more useful. Magic is lovely until someone switches the lights on. Psychology keeps working.
When I trace Ashida Kim’s published work, I see the shape of the late twentieth-century martial arts world around it. I checked WorldCat and found Secrets of the Ninja listed as a 1981 Ashida Kim title, and Forbidden Fighting Techniques of the Ninja listed as a 1984 title. Ashida Kim’s official site also says Paladin Press published several of his books, including Secrets of the Ninja, Ninja Mind Control, Hands of Death, and Forbidden Fighting Techniques. That places the material right inside the American martial arts boom, the paperback era, the age of mail-order danger, secret manuals, comic-book intensity, survival culture, Cold War suspicion, and the enormous Western appetite for ninja mystery. People can laugh at that era now, but they should be careful. Every generation has its own costume. The 1980s had black hoods and forbidden manuals. We have podcasts, algorithmic outrage, and men selling enlightenment from a rented studio with LED lights. Let us not get smug too quickly.
The Black Dragon Fighting Society is part of that wider atmosphere too. In The Believer interview, Ashida Kim says the Black Dragon Fighting Society in the United States was founded by Count Dante and that he encountered Dante in Chicago in 1968. WBEZ’s reporting on John Keehan, known as Count Dante, gives a broader view of the Chicago martial arts scene, with its karate tournaments, social tensions, rough rivalries, and larger-than-life personalities. I do not bring that up to turn the article into gossip in a gi. I bring it up because martial arts do not float in heaven untouched by culture. They grow out of cities, friendships, grudges, magazines, advertisements, bruises, hopes, egos, and the strange human urge to turn hardship into theatre. Mugei-Mumei no Jitsu carries that American undercurrent. It has Japanese language and ninja imagery, yes, but it also has the flavour of American self-invention. It walks like something that came through books, challenge culture, underground reputation, and the stubborn belief that if the established gatekeepers will not open the door, one may as well find the window. Or the roof. Or the shadow beside the door.
The first technical principle I see is simple enough to make sophisticated people uncomfortable: do not be where harm lands. In The Believer interview, the line “The enemy can’t hit you if you’re not there” sits right at the centre of the presentation, and I think that one sentence explains more than a thousand dramatic poses ever could. It sounds almost too obvious, which is why people overlook it. Martial artists love complexity. We love names, mechanics, angles, training drills, historical claims, rank, ritual, and occasionally the delicious feeling of being right in public. But the body does not care about our little ceremonies when force arrives. The body cares whether we were in the way. Mugei-Mumei no Jitsu begins from that hard little truth. I find that both humble and rebellious. Humble because it admits flesh has limits. Rebellious because it refuses the stupid pride of standing there just to prove one can.
When I read Secrets of the Ninja, I see that same pattern in the structure of the material. The table of contents includes espionage, basic ninjitsu, meditation for inner strength, kuji kiri, Inpo or the art of hiding, the Nine Steps, obstacle course training, hiding places, covert entry, Tonpo or the art of escaping, clouding the mind, and leaving no trace. That is not a normal sporting curriculum. It does not read like “jab, cross, hook, sprawl, pass guard, collect medal, complain about judging.” It reads like a catalogue of disappearance and control. The body is trained, yes, but the body is not alone. The mind, environment, timing, shadows, breath, silence, and perception all become part of the art. That is what makes it interesting. It does not merely ask, “How do I win the exchange?” It asks, “Why am I accepting this exchange in the first place?” That question is dangerous to ego. Ego likes a stage. Survival prefers an exit.
The Nine Steps, or Kuji Ashi, are especially revealing because they place movement inside the logic of invisibility. Secrets of the Ninja describes moving through darkness, using shadows, controlling breathing, choosing concealment, and using Kuji Ashi as a way to become unseen in practical terms. That is the kind of technique people misunderstand if they only think in terms of punching power or competition exchange. Silent movement is not there to look mysterious. It is there to change the terms of contact. A person who controls distance and attention is already shaping the outcome before hands are raised. A person who knows how to lower the body, soften the breath, break silhouette, and use the room is not merely “hiding.” That person is refusing to give the other side a clean target, a clean rhythm, or a clean story. Very rude, really. Excellent manners at the dinner table, dreadful manners for anyone hoping to dominate you.
Then there is “clouding the mind,” which I think is one of the most important phrases in the whole discussion. I do not need to wrap it in incense and whisper as if the curtains are listening. The idea is plain: people do not respond only to reality; they respond to what they think is happening. Shift that perception and the situation changes. In everyday life, people do this constantly, though they may not call it ninjutsu because that would make the office meeting more interesting than management allows. Silence can cloud the mind. A pause can cloud the mind. A calm face can cloud the mind. An unexpected angle, an absence, a refusal to answer the emotional bait - all of it changes perception. In martial terms, that becomes misdirection, timing, concealment, distraction, rhythm-breaking, and escape. In human terms, it is the art of not handing another person the steering wheel of your nervous system. Which is useful, because some people drive like they have been raised by angry furniture.
I also see meditation as central, not as decorative mysticism sprinkled over the serious bits like parsley on a dubious pub meal. Secrets of the Ninja presents meditation as a way to cultivate mind and body, sharpen perception, develop psychological insight, calm the mind, and build inner strength. Ninja Mind Control, in its table of contents, moves through the warrior-mystic idea, breathing exercises, kuji-kiri, internal strength, mental powers, and related esoteric material. I know some readers get nervous when words like qi, ki, kuji-kiri, and inner power enter the room. Half of them want to believe everything; the other half want to set fire to the curtains in protest. I prefer a third option: I look for the practical layer. Breath changes fear. Visualisation changes readiness. Ritual can organise attention. Stillness can stop panic from eating the steering wheel. Whether one reads the esoteric language literally, symbolically, or as training psychology wearing old robes, the practical thread remains: the mind must be trained because the mind is where many confrontations are lost before the body moves.
That is where the philosophy of Mugei-Mumei no Jitsu becomes sharper than it first appears. “No Name, No Art” is not just a refusal to advertise a brand. It is also a refusal to be captured by definition. Ashida Kim’s own “Dojo Politics” page says he created the 21st-century martial art called Mugei-Mumei no Jitsu and explains the name as not getting hung up on names, while also saying that eventually every martial artist finds a few methods that work for them and returns to those proven things. I find that wonderfully honest. After enough years, every martial artist becomes a personal weather system. The boxer has favourite angles. The judoka has favourite grips. The grappler has the same horrible choke arriving with the inevitability of a tax bill. The karateka has one counter they trust more than most relatives. The label remains, but the body edits. The art becomes personal or it remains theatre. And even theatre, to be fair, needs rehearsal.
The “no name” part also speaks to secrecy and information control. I do not mean childish secrecy, the sort where a man in a black outfit claims he cannot show you the technique because your aura has not filled in the paperwork. I mean strategic privacy. The less a hostile person knows about your intention, rhythm, skill, fear, habits, and weaknesses, the less material they have to use. That is not paranoia. That is common sense with better posture. In an age where people publish their routines, locations, insecurities, arguments, grudges, breakfast, and emotional collapse in high definition, “No Name, No Art” feels almost radical. Keep something back. Do not narrate your entire inner world to the crowd. Do not confuse visibility with value. The modern person wants to be seen; the ninja question is whether being seen is always wise. That is a rather inconvenient question for an age addicted to performance.
Dojo Press presents Mugei-Mumei no Jitsu as a very direct self-defence idea, built around a simple distraction-and-escape principle rather than a long, ornate road through endless formal methods. I am not going to turn this post into a manual for unpleasant behaviour, because the internet has enough people with bad judgement and excellent Wi-Fi. What matters here is the philosophy behind the simplicity: survive, create space, avoid needless damage, and leave. That is more provocative than it sounds. Martial culture often says escape is noble and then secretly worships the person who stays and suffers beautifully. I have never understood this. I respect courage, but I do not worship preventable injury. There is a difference between bravery and volunteering your face for a lesson the universe did not ask you to attend.
This is also why I do not read the art as anti-martial. I read it as anti-ego. Ashida Kim writes that ninjitsu is not about fighting but about keeping the peace, and his “Ashida Kim on War” piece frames the warrior mood as waiting, self-control, yielding to superior force, using intelligence, understanding self and opponent, and making “first, do no harm” a guiding law. That does not sound soft to me. It sounds difficult. Anyone can become loud. Anyone can clench a fist. Anyone can confuse tension with strength, especially after two coffees and a motivational video. But waiting? Yielding without collapsing? Staying calm when insult invites stupidity? Leaving when pride demands theatre? That is harder. That is why peace, real peace, is not passive. It is disciplined. It has teeth, but it keeps them behind the lips until needed. Very British, in a way. Like sarcasm with a moral code.
I like the paradox inside this art: it speaks of peace, but it does not pretend the world is harmless. That is important. A philosophy that cannot look at danger without fainting onto a velvet cushion is not a martial philosophy. It is interior design. Mugei-Mumei no Jitsu, as I read it, says that harm exists, cruelty exists, pressure exists, and some people do not stop simply because one has quoted wisdom at them in a soothing voice. But it also says the answer is not to become addicted to violence. The answer is to cultivate intelligence, timing, restraint, breath, decisiveness, and the ability to vanish from the line of harm. It is not romantic pacifism, and it is not chest-beating. It is closer to: be kind, be ready, be hard to read, and do not stand in front of the cart just because someone challenged your honour in the marketplace. Honour is lovely. So are functioning knees.
I also think people misunderstand the weapons and tools side if they turn it into pure fantasy. Secrets of the Ninja mentions classical tools and improvised methods, but it also says the study of the art does not require weapons, and that a person alone in an empty room can practise ninjitsu. That line is more important than the catalogue of exotic objects. The real point is adaptability. Tools are useful because they solve problems, not because they look good in photographs. Historical ninja material, as presented by the Iga-ryu Ninja Museum, also includes practical self-defence implements and farm tools, which reminds me that the old world was often less theatrical than the modern imagination makes it. A tool was a tool. A disguise was a disguise. A shadow was a shadow. If it worked, it worked. If it did not, no amount of dramatic music would save it.
Now, I know someone will want the category question. Someone always does. Is Mugei-Mumei no Jitsu a classical Japanese koryu in the strict technical sense? I do not think that is the most useful way to frame the article, because Ashida Kim’s own wording names it as a 21st-century martial art, and I am taking that wording seriously. Koryu.com explains that koryu means old flow or classical martial tradition, with lineage, social structure, teacher-student transmission, and a historical stream going back through generations; it also says modern ninjutsu and ninjutsu-derived arts do not fall within its definition of koryu bujutsu. I can respect that category without using it as a club. Categories help. They are not gods. A modern art can still be meaningful. A personal art can still contain useful ideas. A system can be outside one historical classification and still deserve careful reading. I know this ruins the fun for people who prefer every conversation to end with a stamp marked “approved” or “burn immediately,” but I shall carry on bravely.
For me, the more interesting question is not whether Mugei-Mumei no Jitsu satisfies every possible external demand. It is whether it expresses a coherent martial logic. I think it does. I see the logic in the name. I see it in the emphasis on evasion and invisibility. I see it in the attention to hiding, escape, clouding the mind, breath, meditation, and leaving no trace. I see it in the refusal to confuse self-defence with sport. I see it in the idea that a person should not be trapped by style names, not reveal too much, not give the other side a clean target, and not mistake public performance for private readiness. That is a complete philosophy, even if it is not organised like a modern academy syllabus. It is more like a survival current. It moves under the floorboards. Which is inconvenient if you like everything laminated.
I also think there is something genuinely rebellious in calling an art “No Name, No Art.” Martial arts are often full of banners. Names. Certificates. Ranks. Crests. Patches. Photographs. Titles long enough to need their own administrative assistant. I am not mocking all of that; structure can preserve knowledge, and respect for teachers matters. But the obsession with identity can become a trap. “I am this style.” “I am this rank.” “I am this lineage.” Fine. But what happens when the situation does not care? What happens when the rhythm changes, the ground is wrong, the lighting is bad, the person is bigger, fear arrives, and your favourite label is standing there looking embarrassed? Mugei-Mumei no Jitsu seems to whisper: do not be owned by the name. Use what works. Keep peace where possible. Survive where necessary. Leave less trace than ego would prefer.
That is why I do not see the art as merely “ninja-themed,” although the imagery is obviously there and often dramatically so. I see it as a meditation on formlessness, self-command, and strategic absence. The ninja imagery gives it theatre, and theatre is not automatically bad. Martial arts have always had theatre. Bowing is theatre with ethics. Uniforms are theatre with laundry. Kata is memory staged in the body. Ring entrances are theatre with sponsorship. Even the serious people are performing seriousness. The question is not whether theatre exists. The question is whether the theatre carries something useful or only feeds vanity. In Mugei-Mumei no Jitsu, I think the useful thing is this: disappear from the expected script. The aggressor expects resistance in a certain form. The crowd expects a contest. Pride expects a speech. The art says: perhaps not. Perhaps the answer is elsewhere. Perhaps the empty space is the technique.
I find that deeply modern, perhaps more modern than some people realise. We live in a world where everyone wants reaction. Brands want reaction. Politics wants reaction. Strangers online want reaction. Enemies want reaction. Even friends sometimes want the version of us that performs predictably. Mugei-Mumei no Jitsu, read philosophically, says I do not have to provide the expected shape. I can choose silence. I can choose distance. I can choose timing. I can choose not to explain myself to people who are only collecting ammunition. I can choose to let someone swing at the ghost of their own assumption while I quietly go and make tea. This is not cowardice. It is economy. There is a difference. One is fear. The other is not wasting life on fools with dramatic lighting.
Of course, an art like this will always irritate people who want martial skill to look a certain way. Some want ring proof. Some want scroll proof. Some want a neat family tree. Some want a body count, which is a charming little hobby if one has the ethical depth of a puddle. I prefer to ask what the art trains the practitioner to value. In this case, I see values of concealment, peace, mental discipline, confidence, misdirection, survival, and personal adaptation. I see the idea that one can be dangerous without being loud, peaceful without being helpless, and humble without being weak. That is a difficult balance. Most people fall off one side or the other. They become either brittle pacifists who hope evil respects their softness, or noisy tough people who treat every inconvenience as a battlefield. I have little patience for either. The world requires kindness with a spine.
The history of Mugei-Mumei no Jitsu also reminds me that martial arts are living arguments. They are not only techniques; they are answers to the problems of their time. Classical systems answered the needs of their worlds. Modern systems answer modern needs. Ashida Kim’s work came through the paperback-and-video era, through the appetite for secrets, through the Western fascination with ninjutsu, through the rough American martial arts scene, and through his own stated emphasis on self-defence and peace. I do not need to pretend that this is the same historical category as a feudal ryu to take it seriously as a modern martial expression. In fact, calling it modern may be the more respectful reading, because that is the language he uses for Mugei-Mumei no Jitsu himself. A 21st-century martial art. No Name. No Art. Not trapped. Not tidy. Not asking permission from the museum guard.
When I step back from the books, interviews, historical comparisons, and all the noise around the subject, I am left with a surprisingly clean set of ideas. I am left with the refusal to take needless harm. I am left with the art of being unseen in practical and psychological ways. I am left with breath, meditation, and attention as tools of survival. I am left with simple self-defence over elaborate ego. I am left with the importance of peace without naivety. I am left with the warning not to be trapped by names, even the names we love. I am left with the idea that the greatest victory may not look like victory to spectators, because spectators usually arrive too late and understand even later. They see the empty room and ask where the fight went. Exactly. That may be the point.
So I write about Mugei-Mumei no Jitsu with respect, but not with my eyes closed. I respect the name because it is the name used in the material. I respect the philosophy because it makes me think. I respect the historical conversation enough not to blur categories. I respect the technical material enough not to reduce it to jokes about costumes. I respect the humour of it too, because any martial art that cannot survive a little humour is probably a religion with a warm-up routine. And I respect the central provocation most of all: what if the highest expression of martial skill is not always to overpower, but to prevent the moment from owning you? What if the real art is the discipline to vanish from the wrong contest? What if “No Name, No Art” is not a lack of identity, but freedom from the vanity of identity?
I suppose that is where I land. Mugei-Mumei no Jitsu is the name I use because it is the name Ashida Kim’s own material gives me. I read it as a modern ninjitsu-based martial philosophy of evasion, concealment, misdirection, mental cultivation, practical self-defence, and peace with teeth. I place it historically inside the late twentieth-century martial arts world, while also recognising the older ninjutsu themes of intelligence, psychology, strategy, and disappearance that echo through it. I do not need to flatten it into somebody else’s category to understand it. I do not need to turn it into a courtroom drama. I can simply look at the art and let it speak in its own strange, stubborn, shadowed voice. And what it says, to me, is wonderfully inconvenient: do not be so eager to be seen, do not be so proud that you stand where harm expects you, do not confuse the label with the lesson, and do not mistake noise for power. Sometimes the most rebellious thing a martial artist can do is not to strike harder, shout louder, or collect another title. Sometimes the most rebellious thing is to leave behind only silence, timing, and the faint embarrassment of someone who prepared to defeat a person who is no longer there.
