How to use it

State the time or situation in which the following clause happens.

  • The tense of the verb BEFORE 「とき」 determines the order: 「日本へ行くとき」 = before arriving (haven't arrived yet), 「日本へ行ったとき」 = after having arrived.
  • A noun must have 「の」: 「子どものとき」, not 「子どもとき」.

Examples

  • When you play in the park, let’s wear a hat.

  • When I was a child, I often swam in the river.

Keep in mind

  • Can also be written in kanji as 「時」.

Common mistakes

  • Wrong子(こ)どもとき、よく川(かわ)で泳(およ)ぎました。

    When I was a child, I often swam in the river.

    Correct子(こ)どものとき、よく川(かわ)で泳(およ)ぎました。

    A noun connecting to 「とき」 must go through 「の」.

  • Wrong公園(こうえん)で遊(あそ)びますとき、帽子(ぼうし)をかぶりましょう。

    When you play in the park, let's wear a hat.

    Correct公園(こうえん)で遊(あそ)ぶとき、帽子(ぼうし)をかぶりましょう。

    Before 「とき」, use the PLAIN form, not the ます form.
