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.
