Meaning & Definition

Senmon (専門) means ‘specialty’ or ‘expertise’ and describes one’s field of professional or academic expertise. It’s essential vocabulary for discussing careers, education, and professional qualifications in Japanese.

Senmon describes an area of specialized knowledge, profession, or academic field. ‘Watashi no senmon wa keizaigaku desu’ (My specialty is economics).
