How to say "oneself" in Japanese

Choosing the right word
  • 自身じしんJLPT N3approx.Common
    noun, noun (suffix)Emphatic 'oneself': it singles out the very person in question, as in 'I myself' or 'the man himself'; use it when you want to stress that it was that person and no other.
    ジェーン自身じしんがこの手紙てがみを書かいた。↗
    Jane wrote the letter herself.
  • 自らみずからCommon
    noun'Oneself' as the doer: used when a person does something personally or of their own accord rather than leaving it to others — think 'he came in person to apologize'.
    彼かれは自みずからを日本にっぽんのエジソンと称しょうした。↗
    He called himself an Edison of Japan.
  • 己おのれCommon
    pronounA poetical word for 'oneself'; you will meet it in literature and fixed expressions far more than in conversation, and it is seldom the word you want for everyday reference to yourself.
    他人たにんを己おのれを持もって計はかってはいけない。↗
    You must not judge others by yourself.
  • 自己じこJLPT N1approx.Common
    no-adjectiveThe abstract 'self' of psychology, philosophy, and analytical writing: it treats the self as a concept, so it suits such contexts better than casual talk about yourself.
    彼かれは自己じこを没却ぼっきゃくする男おとこではない。↗
    He knows how to assert himself.
  • 素すCommon
    nounReally points to a person's natural, unadorned state — their true nature and feelings as they are — so it fits 'one's true self' and is not a general-purpose word for 'oneself'.
    どうやら、さっきのは演技えんぎではなく、素すだったらしい。↗
    It seems like that she wasn't acting back then; they were her real feelings.

Choose 自身 to emphasize the person themselves, 「自ら」 for doing something personally or of one's own accord, 自己 for the abstract 'self' of psychology and philosophy; 己 is poetical, and 素 means one's natural, unadorned self.
