I honestly don't know what a dao chang is. Where's that from?
Dao chang, dojo, do jang...all use the same Chinse characters and carry the same meaning. Dao chang is simply Chinese.

In Japan, dojo originated far earlier than Japanese karate with the various samurai arts, such as kendo/kenjutsu/iaijutsu, the various systems of jujutsu, etc.
