How to say "guy" in Japanese

Choosing the right word
  • やつCommon
    nounAn informal, conversational word for a fellow, usually written in kana; use it in relaxed speech to refer to some man, with a tone that can be casual, dismissive or roughly familiar.
    欠点けってんはあるけれども、彼かれはいい奴やつだ。↗
    For all his faults, he is a good fellow.
  • 野郎やろうCommon
    nounA rough, masculine term for a man; it ranges from a genuine insult to coarse banter between male friends, so it does not suit polite conversation or neutral description.
  • ガイCommon
    nounThis is mainly the katakana rendering of the personal name Guy; as a common noun meaning 'guy' it is seldom the word you want, so do not reach for it in everyday contexts.
  • 男おとこJLPT N5approx.Common
    nounThe plain word for a man, covering 'guy' in the neutral sense of simply a male person; it carries no roughness or slangy flavour, so it is the safe choice for straightforward reference.
    あんな男おとこ見みても胸むなくそが悪わるい。↗
    I can't bear the sight of him.

Choose 男 when you simply mean a man, 「やつ」 for casual reference to a fellow, 野郎 for rough talk that can be insulting or friendly banter, and skip 「ガイ」, which is really the borrowed name Guy.
