A teacher or instructor in Japanese martial arts, literally meaning 'one who has gone before.' The title represents not just technical knowledge but also the responsibility to guide students in character development and martial philosophy.
From Japanese 'sensei,' combining 'sen' (before/previous) and 'sei' (birth/life), meaning 'born before' or 'one who came first.' Originally used for teachers, doctors, and other respected professionals in Japanese society, it became integral to martial arts culture through the master-student relationship.
The sensei-student relationship in martial arts goes far beyond technique instruction—it's a mentorship that traditionally extends to life guidance and character building, which is why many students maintain lifelong connections with their first sensei. In Japan, calling someone 'sensei' incorrectly or too casually is considered disrespectful, as the title carries significant social weight.
