How to say "scam" in Japanese

Choosing the right word
  • 詐欺さぎJLPT N1approx.Common
    nounThe default word for a scam or fraud in the sense of cheating people out of money or goods. Use it for schemes, con artists, and victims: calling a scheme a 詐欺 is the natural way to label it.
    私の知しる限かぎり、彼かれはその詐欺さぎの企たくらみには関与かんよしていません。↗
    To my knowledge, he has not been involved in the fraud scheme.
  • 詐欺るさぎる
    godan verb, transitive verbThe verb form, covering 'to scam, defraud, swindle'—that is, the action itself rather than the scheme. It is less common and slangy; many speakers prefer verb phrases built on 詐欺 instead, so treat it as a casual option.
  • 人騙しひとだまし
    nounA less common noun for deception or scamming in the sense of tricking people, rather than a specific financial scheme. It is rarely the word you reach for to name a scam; 詐欺 is the usual choice.
  • 人たらしひとたらし
    nounA less common noun meaning a scam or con trick, again with the nuance of deceiving people rather than a formal fraud. Seldom the word you want; 詐欺 covers typical scam situations far more naturally.

For the ordinary crime of swindling someone out of money, use 詐欺; the verb 「詐欺る」 is slangier; 「人騙し」 and 「人たらし」 are less common nouns for tricking people.
