Bugei is a more general term that encompasses all martial arts, although it is sometimes used to indicate emphasis on traditional or ancient martial arts, as opposed to the modern sport-oriented martial arts. This term is used to refer to the traditional martial arts that emphasize self-defense and self-improvement that have been passed down through generations. Japanese martial arts are a unique combination of physical and mental training, with the ultimate goal of self-improvement. These three terms, budō, bujutsu, and bugei, are often used interchangeably to refer to the same concept: the practice of traditional Japanese martial arts.
