How to say "acquaintance" in Japanese

Choosing the right word
  • 知り合いしりあいJLPT N2approx.Common
    nounThe everyday word for an acquaintance as a person: someone you know, typically less close than a friend. This is usually the word you want when referring to a person.
    どこで彼女かのじょと知り合しりあいになったのか。↗
    Where did you get to know her?
  • 交わりまじわりCommon
    nounReally means relations, fellowship or association with others, so it fits 'acquaintance' only in that abstract sense; for a specific person you know, it is seldom the word you want.
  • 知人ちじんJLPT N2approx.Common
    nounA person one knows; broader than 知り合い, since it can also mean a friend. A slightly formal term for referring to someone by their relationship to you.
    もし私の家いえが大だい邸宅ていたくだったら私の誕生日たんじょうびのパーティーには知人ちじんをみんな招待しょうたいするのだが。↗
    If my house were a mansion, I would invite everyone I know to my birthday party.
  • 面識めんしきCommon
    nounDenotes the fact of being acquainted with someone — knowing them from having met — rather than the person; used when saying whether you have met someone before, and not for the person themselves.
    私はスミス氏しと面識めんしきがある。↗
    I am acquainted with Mr Smith.
  • 近づきちかづきCommon
    nounCan mean a person one has come to know or the act of making someone's acquaintance, suggesting getting close to someone; for an ordinary acquaintance it is seldom the word you want.
    職業柄しょくぎょうがら彼かれは数すう人にんの外国人がいこくじんと近ちかづきになっている。↗
    His job has brought him in contact with some foreigners.

Use 「知り合い」 or 知人 for an acquaintance as a person, 面識 for the fact of having met someone, 「交わり」 for association or fellowship, and 「近づき」 for getting to know someone or the person so known.
