The Niju Kun

Karate-do wa rei ni hajimari rei ni owaru koto a wasaru na 
Karate-do begins and ends with rei 

Karate ni sente nashi 
There is no first strike in karate 

Karate wa, gi no taske 
Karate stands on the side of justice 

Mazu onore o shire, shikashite ta o shire 
First know yourself, then know others 

Gijitsu yori shinjitsu 
Mentality over technique 

Kokoro wa hanatan koto o yosu 
The mind must be set free 

Waza wai wa ketai ni seizu 
Calamity springs from carelessness 

Dojo nomino karate to omou na 
Karate goes beyond the dojo 

Karate-do no shugyo wa isssho de aru 
Karate is a lifelong pursuit 

Ara yuru mono o karateka seyo; sokoni myomi ari 
Apply the way of karate to all things. Therein lies its beauty 

Karate Wa Yu No Gotoku Taezu Netsu O Atae Zareba Motono Mizuni Kaeru 
Karate is like boiling water; without heat, it returns to its tepid state 

Katsu kangae wa motsuna; makenu kangae wa hitsuyo 
Do not think of winning. Think, rather, of not losing 

Tekki ni yotte tenka seyo 
Make adjustments according to your opponent 

Tattakai wa kyo-jitsu no soju ikan ni ari 
The outcome of a battle depends on how one handles emptiness and fullness (weakness and strength) 

Hi to no te-ashi wa ken to omoe 
Think of the opponent’s hands and feet as swords 

Danshi mon o izureba hyakuman no teki ari 
When you step beyond your own gate, you face a million enemies 

Kamae wa shoshinsha ni atowa shizentai 
Kamae is for beginners; later, one stands in shizentai 

Kata wa tadashiku, jisen wa betsumono 
Perform kata exactly; actual combat is another matter 

Chikara no kyojaku tai no shinshuku waza no kankyu 
Do not forget the employment of withdrawal of power, the extension or contraction of the body, the swift or leisurely application of technique 

Tsune ni shinen ku fu seyo 
Be constantly mindful, diligent, and resourceful, in your pursuit of the Way 


The niju kun is the list of twenty (‘ni’ being two, and ‘ju’ being ten) precepts laid out by Gichin Funakoshi that are intended to help the student and instructor alike understand the nature of karate and the ultimate goal of karate: the improvement of the self. The simple principles of the dojo kun derive directly from these precepts, and the same ideas can be seen within both. The translations given above are approximate, and are taken from The Twenty Guiding Principles of Karate by Funakoshi (1938). The precepts laid out in the niju kun are more involved and subtle than those of the dojo kun, and require more study to discover their meaning in relation to both karate training and the conduct of the self outside of the dojo.
