Dojo entry from Wikipedia

An interesting, albeit very brief, description of dojo.

I wanted to share this part:

A proper Japanese martial arts dōjō is considered special and is well cared for by its users. In many styles it is traditional to conduct a ritual cleaning of the dōjō at the end of each training session (called souji, which translates from Japanese as "cleaning"). Besides the obvious hygienic benefits of regular cleaning it also serves to reinforce the fact that dojo are supposed to be supported and managed by the student body, not the school's instructional staff.
