A dojo (道場 dōjō) is a Japanese term which literally means "place of the way". Initially, dōjō were adjunct to temples. The term can refer to a formal training place for any of the Japanese do arts but typically it is considered the formal gathering place for students of any Japanese martial arts style to conduct training, examinations and other related encounters.

A 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 sōji, which translates from Japanese as "cleaning"). Besides the obvious hygienic benefits of regular cleaning it also serves to reinforce the fact that dōjō are supposed to be supported and managed by the student body, not the school's instructional staff.
