The Twenty Precepts of Karate and Their Meanings

20 precepts of karate written in Japanese by Master Gichin Funakoshi

Master Gichin Funakoshi, the father of modern karate, wrote the 20 precepts of karate or the Niju Kun which was published with commentary by Genwa Nakasone in a book titled “The Twenty Guiding Principles of Karate” in 1938.

These precepts convey karate philosophy and its principles and reflect Bushido and Zen spirits. Let’s have a look at them below.

1. Never forget: karate begins with rei and ends with rei

Rei means courtesy or respect and is represented in karate by bowing.

We bow many times at each karate lesson: at the beginning and at the end of each karate lesson, when receiving personal instructions, when partnering up, when using training equipment, and before and after a sparring session with your partner.

We do this to show respect to our instructors, partners, training equipment, and our place of training.

And this respectful attitude should not be confined to the dojo floor. As you train and make karate a part of your life, this respectful manner should become part of your character.

Life is short and the world is small. You will surely brighten someone’s day up and yours too with your courtesy and respect.

It takes restraint to show respect to someone who doesn’t deserve it, but if you are disrespectful to such a person, you stoop down to their level, and that’s useless.

You might meet someone who you don’t think deserves your respect, but if you are being disrespectful to that person, you’ll stoop down to their level.

Remember the opening line of The Great Gatsby:

In my younger and more vulnerable years, my father gave me some advice that I’ve been turning over in my mind ever since. ‘Whenever you feel like criticizing any one,” he told me, “just remember that all the people in this world haven’t had the advantages that you’ve had”

The arrogant, the totally selfish, the foul-mouth, the homeless and the alcoholic may not have had the kind of upbringing you had. Show empathy and treat them with respect as you would with more fortunate people.

2. There is no first attack in karate (karate ni sente nashi)

Karate is the art of self-defense, first and foremost. We should only use what we learn in karate to defend ourselves and not to provoke conflicts and seek violent encounters.

Even when faced with challenges and conflicts, physical forces should not be the first port of call. Only after all other non-physical means have been exhausted that one would resort to physical weapons, or hands and feet as in the case of karate practitioners.

“A sword must never be recklessly drawn” was the most important tenet of conduct in the daily life of a samurai. It was essential for the honorable man of the day to bear things to the very limit of his ability before taking action. Only after reaching the point where the situation could no longer be tolerated was the blade drawn from its scabbard…

In karate, the hands and feet can be as deadly as the blade of a sword. Thus, the principle that “there is no first strike in karate” is an extension of the basic samurai principle that one must avoid the reckless use of weapons. It underscores the absolute necessity of patience and forbearance.

Gichin Funakoshi

While you definitely should not initiate a fight, it does not mean you should not strike first when a fight is unavoidable.

… karate ni sente nashi … means that you should not cause harm indiscriminately, and if you are forced to, that is, when it is unavoidable, and the enemy tries to harm you, you must stand up and fight ferociously.

When entering a fight, it is essential to dominate the enemy, and to dominate the enemy, you must move (attack) first. Therefore when entering a fight, you must move (attack) first. This is important to keep in mind.

3. Karate supports righteousness

“With great power comes great responsibility”.

While you shouldn’t use your karate skills to cause conflicts, if conflicts arise, you should use what you know to the best of your ability to defend, protect and support what you believe is right.

Karate is a martial art in which the hands and feet are like swords, and it must not be used unjustly or improperly.

Karate practitioners must stand on the side of justice at all times and only in situations where there is no other choice should their power find expression through the use of their hands and feet as weapons.

Gichin Funakoshi

4. First understand yourself, then understand others

This would make many immediately think of Sun Tzu’s saying “Know yourself, know your opponent, hundred battles, hundred victories“.

In the context of karate, my interpretation is that you need to understand your strengths and weaknesses and train accordingly. For example, if you are a small person who is not very flexible with short legs, mawashi geri is unlikely to do a lot of damage. So train with an analytical mind and find out what you are good at and what you are not good at. The next part is to understand your opponent or simply your training partner and use appropriate strategies.

5. The art of developing the mind is more important than the art of applying techniques

Training in karate involves the development of mind, body, and spirit and Gichin Funakoshi’s view is the development of the mind is far more important than the others.

In karate, most of the time you learn to block, punch and kick and there is not much time where your instructor would stop to talk about developing the mind. But that would come about gradually and subtly through years of training. You develop a strong mind, resilience, confidence, and a sense of justice by turning up to train no matter what, pushing through and mastering a difficult technique or a kata, having an open mind and continually seeking to better yourself, being there and helping your training partner and supporting your karate family.

6. The mind needs to be free

The mind needs to be free of judgment, your own knowledge, worries, plans, and anticipations so that you can be readily open to new ideas, instructions, and situations to learn, adapt and deal with them accordingly.

7. Trouble is born of negligence

If you are careless in training, problems will ensue. Every single karate technique when mastered can be deadly and if you are not careful, you can easily cause serious injury to yourself and your training partner.

8. Do not think karate belongs only in the dojo

This will come unconsciously to you as you travel along your karate journey. If you put the effort into your training and try to learn as much as you can from the art, you will find that karate influences you in and out of the dojo. You will be more disciplined, more confident, and more respectful and act with integrity.

9. Karate training requires a lifetime

People learn karate for different reasons, for physical fitness, for self-defense, or simply for being part of a community. But for those who love karate and the many things it has to offer, training in karate is a lifelong pursuit.

There is so much to learn from karate and you will be only scratching the surface even if you spend your whole life studying the art.

10. Transform everything into karate; therein lies its exquisiteness

You can apply many things that you learn in karate to different aspects of your life. For example, being respectful to people you meet in daily life, having an open mind and listening to your partner when you have an argument or applying what you learn in sparring strategies to solving problems at home and at work

11. Genuine karate is like hot water; it cools down if you do not keep on heating it

This one is obvious. If you want to continually improve your karate, you need to practice it regularly, there is no other way around it.

Both physical and mental fitness can’t be stored. To retain it, you need to continually work on it and challenge yourself.

12. Do not think of winning; you must think of not losing

If you are in a tournament match, you may not know what your opponent is like. He or she could be far better than you technically or could be a definite underdog. If you have the mindset that you must win, you will put pressure on yourself, become tense, and are less likely to be ready to react to the fight as best as you can.

You shouldn’t think about losing either before a fight. Thinking that you’d lose means you’ve already surrendered to your opponent, your spirit is down, you are unlikely to actively defend yourself or deploy techniques and strategies to overcome your opponent.

Instead, don’t think about losing and winning and fight to the best of your ability. If you lose against a better opponent, have no regret. If you win against a poor opponent, it’s fair.

13. Transform yourself according to the opponent

This precept is pretty obvious. Unless you are technically superior to your opponent and can dictate the fight, you need to remain flexible and adapt to the individual opponents.

14. The outcome of the fight depends on one’s control

The above is the translation of this precept published on the JKA website.

A more clear translation is “The outcome of a battle depends on how one handles emptiness and fullness (weakness and strength)” which doesn’t need interpretation.

15. Imagine one’s arms and legs as swords

As karate is the art of empty-hand fighting, you need to use your whole body as a weapon, not just your arms and legs. And they all can be deadly weapons at that.

16. Once you leave the shelter of home, there are a million enemies

Gichin Funakoshi lived in a different time and era but this still can apply today.

We face problems within ourselves and within our own homes.

As we venture further and further away, we face more problems and have more complex issues to deal with. We need to be aware of this fact and aim to maintain a zanshin mindset (a state of relaxed alertness).

And karate teaches us not to invite problems, not to incite conflicts but we should always be ready when problems or enemies come our way.

17. Postures are for the beginner; later they are natural positions

There are many stances in karate (zenkutsu dachi, kiba dachi, sanchin dachi, neko ashi dachi, etc).

They are created to teach people katas because it is easier for instructors to refer to posture names one assumes when performing varying techniques in these katas rather than having to repeatedly describe the specifics of these positions.

For example, in Gekisai Dai Ichi kata, once you learn the specifics of zenkutsu dachi stance, your instructor just needs to say “you need to land in zenkutsu dachi after performing mae geri” and you will know what to do. He or she does not need to describe how far the front leg should be from the back leg or the width between the legs.

These stances are only moment-in-time postures because in an actual fight, you would be moving fluidly and there would be no static stances.

By practicing katas over and over again, these stances will eventually become natural positions.

18. Do the kata correctly; the real fight is a different matter

The first and second statements of this precept seem contradictory to me.

My understanding is that kata is the essence of karate. By performing karate katas over and over again while visualizing fighting an actual opponent, you will develop unconscious reflexes and be able to use them in real fights naturally and effectively. Your kata practice will be reflected in your actual fighting techniques. Accordingly, kata and real fights should be closely connected, otherwise, what is the point of practicing kata.

Do the kata correctly, yes definitely, but experienced karatekas should be able to apply what they learn in kata in real fights.

19. Do not forget control of the dynamics of power, the elasticity of the body and the speed of the technique

This is as true in karate as in any other martial arts. One needs to learn to use a combination of soft and hard power, slow and fast techniques, and the extension and contraction of the muscles.

20. Always be good at the application of everything that you have learned

The above is the translation of this precept published on the JKA website.

Another translation is “Be constantly mindful, diligent, and resourceful, in your pursuit of the Way” which has quite a substantial difference in meaning.

We are all different with different strengths and weaknesses and different circumstances. I think we should look deep into ourselves, find the best way to live the one and the only life we have and figure out our own karate journey. For some, their karate journey could be linear, for others it could be winding and bumpy, but, like other aspects of our lives, if we remain persistent, diligent and creative, we will succeed.
