How to say "mastery" in Japanese

Choosing the right word
  • 体得たいとくCommon
    noun, suru verb, transitive verbMastery as knowledge or skill absorbed through direct personal experience and embodied practice, not just intellectual understanding; the emphasis falls on having genuinely made it your own.
  • 習熟しゅうじゅくCommon
    noun, suru verb, intransitive verbThe most direct choice for mastery of a skill or field: proficiency acquired through study and repeated practice. Typical contexts include becoming proficient in one's work, a technique, or a subject.
    彼かれはフランス語ふらんすごに習熟しゅうじゅくしようとした。↗
    He tried to master French.
  • 制覇せいはCommon
    noun, suru verb, transitive verbHere 'mastery' means supremacy after conquest, not skill: winning a championship or dominating a field or market. For mastery of an art or technique this is not the word you want.
  • 制圧せいあつCommon
    noun, suru verb, transitive verbSeldom the word for mastery: it means gaining total control over people or territory, by force, or suppressing them. Think of military or police control of an area, not hard-won skill.
    軍隊ぐんたいは反乱はんらんを制圧せいあつした。↗
    The army had the revolt well in hand.
  • 熟練じゅくれんCommon
    noun, suru verb, intransitive verbMastery as seasoned expertise: the skill of someone with long experience, or the process of becoming skilled. Suits veteran craftsmen and workers whose proficiency comes from years on the job.
    彼かれはそのゲームに熟練じゅくれんしていた。↗
    He was an old hand at the game.

For skill-based mastery, choose 習熟 (proficiency through practice) or 熟練 (seasoned expertise), while 体得 stresses mastery gained through personal, hands-on experience; 制覇 and 制圧 concern conquest and forcible control, not skill.
