How to use it

States that a state or action B continues throughout the entire time span A.

  • 間 without に emphasizes that two states/actions both last from beginning to end of a span. Clause B is usually a continuous action or state.
  • If B occurs only once at a point within span A, 間に must be used. This is an important pair to distinguish at N4.

Examples

  • I worked part-time every day during summer vacation.

  • While my mother was cooking, I was cleaning the room.

Common mistakes

  • Wrong留守(るす)の間(ま)、友達(ともだち)が一度(いちど)来(き)ました。

    Correct留守(るす)の間(ま)に、友達(ともだち)が一度(いちど)来(き)ました。

    "Came once" is an event occurring at a single point within the time away from home, so 間に should be used.

Exam tips

  • If the second clause has ずっと/毎日 or an ongoing action → 間; if it has 一度/突然 or a one-time change → 間に.
