English phrase "Japanese martial arts". The usage of term "budō" to mean martial arts is a modern one, and historically the term meant a way of life encompassing physical, spiritual, and moral dimensions with a focus of self-improvement, fulfillment, or personal growth. The terms bujutsu and bugei have more discrete definitions, at least historically speaking. Bujutsu refers specifically to the practical application of martial tactics and techniques in actual combat. Bugei refers to the adaptation or refinement of those tactics and techniques to facilitate systematic instruction and dissemination within a formal learning environment.
