JLPT level: N4 · Updated: 2026-05-17 · Canonical: https://hane-app.com/blog/n4-itashimasu/

**いたします** means **the humble form of do**. It is a **JLPT N4** Japanese grammar pattern used to speak humbly about your own action of doing something.

This grammar point often appears in conversation, written explanations, formal notices, and JLPT-style reading questions. If you want to speak humbly about your own action of doing something, **いたします** is a useful pattern to learn after the N5 basics.

## What does いたします mean?

Use **いたします** when you want to speak humbly about your own action of doing something.

Natural translations include:
- to do (humble form)
- I shall do
- to humbly do

The exact English translation changes with context. Focus on what the grammar point does in the sentence first, then choose the English phrase that sounds natural.

## How to form いたします

Noun + いたします / Verb stem + いたします in set expressions

Examples of the pattern:
- 説明いたします
- 確認いたします
- 失礼いたします

Pay attention to the word form before the pattern. Many JLPT N4 mistakes happen because the meaning is understood, but the grammar is attached to the wrong form.

## When is いたします used?

Use **いたします** in situations like:
- speaking about your own actions in business, service, or formal settings
- replacing する in set expressions to show humility
- writing formal emails, letters, and polite phone conversations

Tone and register:
- humble and formal; used by the speaker to lower their own action
- common in business Japanese, customer service, and JLPT N4 reading questions

## いたします example sentences

- 後で確認いたします。 — I will check later.
- 私が説明いたします。 — I will explain.
- 明日ご連絡いたします。 — I will contact you tomorrow.
- 失礼いたします。 — Excuse me.
- 予約を変更いたします。 — I will change the reservation.

Read the Japanese sentence first, then check the English translation. Try to notice what the grammar point contributes: politeness and social level.

## Nuance of いたします

The key nuance is **is a humble polite form of する**.

This matters because **いたします** may look simple in English, but the Japanese form tells you the speaker's social stance toward the listener.

For example:
- In context, **いたします** helps make the sentence more precise than a direct English translation.
- Compared with **します**, it carries a different social weight even when both patterns appear in similar sentences.

## いたします vs します

Both **いたします** and **します** can appear in similar sentences, but they are different.

**いたします**:
- humble form of する; lowers the speaker's own action
- used when speaking to customers, superiors, or in formal contexts

**します**:
- standard polite form of する
- neutral polite; does not carry extra humble nuance

Quick contrast examples:
- 後で確認いたします。 — I will check later. (humble)
- 後で確認します。 — I will check later. (standard polite)

If you are unsure which one to use, consider your relationship with the listener. Are you providing service, speaking to a superior, or writing a formal message? If so, **いたします** is the natural choice.

## Common mistakes with いたします

Watch out for these mistakes:
- Using it with the wrong noun or verb form
- Confusing it with **します** because the English translation can look similar
- Translating it too literally instead of reading the whole sentence context

A good study habit is to write one short sentence and then change only the grammar point. This makes the difference between similar patterns easier to feel.

## Is いたします on the JLPT?

Yes. **いたします** is commonly taught as **JLPT N4** grammar.

That means learners should be able to:
- recognize it in reading
- understand its nuance in context
- use it in simple original sentences

For test preparation, do not only memorize the English gloss. Practice identifying the words around the grammar point, because JLPT questions often test structure and context together.

## Practice questions for いたします

Try making your own sentences with these prompts:
- Write one sentence using the basic pattern.
- Rewrite the sentence with する to compare register.
- Compare it with the related pattern from the comparison section.

Keep the sentences short at first. Once the form feels natural, add time words, places, reasons, or contrast to make the sentence more realistic.

## Learning path for いたします

Use **いたします** as part of your **JLPT N4** keigo and politeness grammar toolkit. Remember that this pattern specifically lowers your own action; it is not used to describe someone else's behavior.

A good review order is:
1. First, make sure you can form **いたします** from common nouns and verb stems without looking at the chart.
2. Next, compare it with **します** in the same sentence to feel the difference in humility.
3. Finally, write three sentences: one using a set expression like 失礼いたします, one with a noun like 説明, and one with a verb stem like 確認. Try swapping in **します** and ask whether the humble nuance is necessary for the listener.
