Nijukun
 

Funakoshi satte upp en kalligrafibild med 20 visdomar om karate  i sin dojo, vilket kallas NiJu-kun (=20 regler). Dessa "regler" är grunden för den fostran och respekt som sprids genom karate till skillnad från många andra kampkonster.

 

 

 

Här är nijukun översatt till engelska:

 

Mr. Funakoshi's 20 Principles of Karate

  1. In Karate, start with a bow and finish with a bow.
  2. There is no first attack in Karate
  3. Karate is a great assistance to justice.
  4. Know yourself first and then others.
  5. Spirit first: techniques second.
  6. Be ready to release your mind.
  7. Accidents come out of idleness.
  8. Do not think that you can learn Karate only in the Dojo.
  9. It will take your entire life to learn Karate.
  10. Karate-ize everything.
  11. Karate is just like hot water. If you do not give heat constantly, it will again become cold water.
  12. Do not think you have to win. Think, rather, that you do not have to lose.
  13. Victory depends on your ability to tell vulnerable points from invulnerable ones.
  14. Move according to your opponent.
  15. Consider your opponent's hands and legs as you would sharp swords.
  16. As soon as you leave home for work, think that millions of opponents are waiting for you.
  17. Low stance for beginners; natural stance for advanced students.
  18. Practicing a Kata is one thing and engaging in a real fight is another.
  19. Do not forget:
          ​(1) light and heavy application of power
          (2) expansion and contraction of the body
          (3) slowness and speed of techniques.
  20. Devise at all times.
