What does the title "Sensei" translate to?

The title "Sensei" translates to "Master Teacher." In Japanese, the term is often used to refer to teachers or instructors in various disciplines, including martial arts. The word itself combines two kanji: "sen," which means "before" or "previous," and "sei," meaning "birth" or "life." Therefore, it conveys the idea of someone who has lived longer and accumulated knowledge, thus able to guide others. This is why the term is used for those who have attained a high level of expertise and are responsible for teaching their students.

The other options do not accurately reflect the meaning of "Sensei." While "martial artist" and "life coach" may describe roles related to guidance or skill, they do not capture the essence of a "teacher" with authority and experience that "Sensei" embodies. "Before Life" is a direct translation of the individual kanji but does not convey the correct significance in context. Thus, "Master Teacher" is the most precise translation that fits the traditional understanding of the term within martial arts and education.
