How to say "alternately" in Japanese

Choosing the right word
  • 代わる代わるかわるがわるJLPT N1approx.Common
    adverbCovers the core sense of 'alternately; by turns', typically for people or things doing something one after another. It is the common, dependable choice when you want to say that two or more parties alternate in an action.
    二人ふたりはかわるがわる試こころみた。↗
    The two tried one after the other.
  • adverbMeans 'alternately; in succession', but it is a less common word, normally written in kana alone. It has a literary flavor, so learners will mostly encounter it in reading rather than need it for everyday speech.
  • 代わり代わりかわりがわり
    adverbGlossed 'alternately; in turn; one after the other', this variant conveys much the same alternation as 代わる代わる. It is less common, however, so it is worth recognizing more than producing.
  • 一つ置きにひとつおきに
    adverbThis one is really 'every other one' — skipping one item each time, as in selecting alternate items — rather than parties taking turns at an activity. It suits 'alternately' only in that spacing sense.
    彼かれらはひとつおきに席せきに着ついた。↗
    They sat down at every other desk.
  • 交代でこうたいで
    expressionMeans 'alternately; by turns' for people taking turns doing something, such as working in shifts or relieving each other. Slightly less common than 代わる代わる, it emphasizes turn-taking among people.

For people or things taking turns, use 「代わる代わる」 or 「交代で」; 「一つ置きに」 means every other one; 「こもごも」 and 「代わり代わり」 are less common alternatives best recognized rather than actively used.
