N4 Integrated Dialogue Lesson 6

Mastering the usage of ~ておく (te-oku) to describe actions done in preparation for the future.

Context

Planning Ahead

Imagine you are hosting a dinner party. Before your guests arrive, you need to clean the room, buy drinks, and prepare the food. In Japanese, when you want to emphasize that you are doing an action in advance to prepare for a future event, you use a specific grammar structure.

This structure helps clarify that the action isn't just happening randomly, but is part of a plan or preparation.
Explanation

The ~ておく Pattern

The ~ておく (te-oku) form is used to indicate that an action is completed in preparation for something else.

Verb-て formおく
To form this, take the te-form of a verb and add おく (oku). In casual speech, this often contracts to ~とく (toku).

Tip

Remember that おく literally means 'to put' or 'to place'. Think of it as 'doing something and putting it in place' for later use.
Examples

Seeing it in Action

Here are examples of how to use this structure in daily life.

ホテル(ほてる)予約して(よやくして)おきます

I will book the hotel in advance.

ホテルほてるhotel予約してよやくしてto book (te-form)おきますおきますdo in advance

明日会議があるので、資料(しりょう)読んで(よんで)おいてください。

Please read the documents in advance because there is a meeting tomorrow.

資料しりょうdocuments読んでよんでto read (te-form)おいておいてdo in advance (te-form)

旅行の前に、チケットを買【っておく】。

Hint: Use the te-form of 買う + おく

I will buy the tickets before the trip (in preparation).

Deep Dive: Advanced Usage

Sometimes ~ておく is used to mean 'leave something as it is'.

If you say '窓を開けておいてください' (Please leave the window open), it means you want the window to remain in that state for a specific reason (e.g., for ventilation). This is a secondary, but very common, usage of the pattern.
