How to say "identity" in Japanese

Choosing the right word
  • nounCovers identity in the abstract sense — one's sense of self, or a group's cultural or national identity. Typical in discussion of self, belonging, and how one is seen.
    Once divorced from key questions of national culture and identity, comparative literature loses its way.
  • 身元みもとCommon
    nounIdentity in the sense of who a person actually is — their background and origins. Used when someone's identity must be confirmed, investigated, or vouched for, as with an unknown person or a new employee.
    彼かれの身元みもとは我々われわれには分わからなかった。↗
    His parentage was unknown to us.
  • 氏名しめいJLPT N2approx.Common
    nounIdentity only in the administrative sense — a person's full name as entered on forms and documents. It really just means one's full name, so it is seldom what you want for identity as selfhood.
    この封筒ふうとうに住所じゅうしょ・氏名しめいを書かきなさい。↗
    Write your name and address on this envelope.
  • 正体しょうたいCommon
    nounIdentity in the sense of a hidden truth brought to light: the true identity of a masked figure or mysterious stranger, or someone showing their true colors. Carries a strong feel of unmasking.
    ついに正体しょうたいを暴露ばくろしたな。↗
    Now you've given yourself away.
  • 身分みぶんJLPT N2approx.Common
    nounIdentity in the sense of social standing or official status, tied to birth and origin. It is really about status rather than who someone is, so it seldom fits personal identity.
    支配人しはいにんはドアを開ひらいて身分みぶんを名乗なのった。↗
    The manager opened the door and identified himself.

Choose 「アイデンティティ」 for identity as a sense of self, 身元 for who someone really is, 氏名 for a full name on documents, 正体 for a hidden or true identity, and 身分 for social standing.
