意味

Required; compulsory; mandatory. Used for subjects or courses that must be taken.

A noun and no-adjective used almost exclusively in academic contexts: 必修科目 (required subject), 必修授業 (compulsory class). The opposite is 選択 (sentaku, elective) or 選択科目 (sentaku kamoku, elective subject). Also used figuratively: 社会人の必修スキル (an essential skill for working adults). Not interchangeable with 必須 (hissu, essential/indispensable), which is broader — 必修 specifically implies a curriculum or formal requirement.
