Why do Karate people break boards?
That is an old tradition. It is no longer practiced on a regular basis. It can be used from time to time as a specific test, but is largely avoided and sometimes sneered at. Unfortunately most people have ended thinking that’s Karate, remember to read Master Funakoshi’s words in Karate-do Nyumon (Kodansha International) on this subject: “Karate-do is a noble martial art, and the reader can rest assured that those who take pride in breaking boards or smashing tiles, or who boast of being able to perform outlandish feats, like stripping flesh or plucking out ribs, really know nothing about karate. They are playing around in the leaves and branches of a great tree, without the slightest concept of the trunk”.
