How to say "individually" in Japanese

Choosing the right word
  • 一人一人ひとりひとりJLPT N3approx.Common
    adverb, nounCovers 'individually' in the sense of treating or considering people one by one, each as a separate individual. It works for physical handling or attention given to each person in turn, one at a time.
    メイドは客きゃくを一人一人ひとりひとり大声おおごえでとりついた。↗
    The maid announced each guest.
  • 口々にくちぐちにCommon
    adverbApplies only when 'individually' describes people speaking: each person in a group voices the same thing, one and all. For other senses of 'individually' this is seldom the word you want; it is really about unanimous speech.
    Everyone complained about the unfair treatment.

Use 一人一人 for people considered one at a time or individually; use 「口々に」 only when several people are each speaking, since it describes speech, not general individual action.
