自信がある vs 自信を持つ: What’s the Difference in Japanese?

Introduction

If you are learning Japanese, you have probably seen both of these expressions:

「日本語には自信があります。」
I’m confident in my Japanese.

「もっと自信を持って話してください。」
Please speak with more confidence.

Both 自信がある (jishin ga aru / to be confident) and 自信を持つ (jishin o motsu / to have or develop confidence) are related to believing in yourself or your abilities.

Because their meanings are so close, many learners wonder whether they can simply use them interchangeably.

Not quite.

The key difference is what the speaker is focusing on.

One describes your current state, while the other focuses more on having, developing, or showing confidence.

Understanding this distinction will help you sound more natural and can also make JLPT vocabulary and reading questions easier.

The Short Answer

自信がある (jishin ga aru / to be confident) describes a state in which confidence already exists.

自信を持つ (jishin o motsu / to have or develop confidence) focuses on having, gaining, or consciously maintaining confidence.

A simple way to remember the difference is:

• 自信がある = being in a confident state
• 自信を持つ = having, gaining, or actively showing confidence

If you are describing how confident someone is now, 自信がある is often the natural choice.

If you are talking about becoming more confident, encouraging someone, or changing their attitude, 自信を持つ is often more suitable.

Understanding 自信がある

自信がある literally contains:

• 自信 (jishin) = confidence
• ある (aru) = to exist, to have

The expression describes a situation in which a person already feels confident about an ability, decision, result, or other matter.

For example:

「私は日本語の発音に自信があります。」
I’m confident in my Japanese pronunciation.

The speaker is describing their current assessment of their pronunciation.

The focus is not on becoming confident. The confidence already exists.

You will also frequently hear the opposite expression:

「自信がない」
to lack confidence / not be confident

For example:

「数学にはあまり自信がありません。」
I’m not very confident in math.

「今回の試験には自信があります。」
I’m confident about this exam.

In these sentences, 自信がある describes the speaker’s present state.

Understanding 自信を持つ

自信を持つ literally uses the verb 持つ (motsu / to have, hold, possess).

It means to have confidence in yourself, your abilities, your ideas, or your decisions.

However, compared with 自信がある, this expression often gives more attention to attitude, intention, or a change in confidence.

Consider this sentence:

「もっと自信を持ってください。」
Please have more confidence in yourself.

The speaker is encouraging someone to change their attitude.

The listener may already have some ability, but they need to believe in themselves more.

Another common example is:

「練習を続けて、自信を持てるようになりました。」
By continuing to practice, I became able to feel more confident.

Here, the sentence describes a change:

little confidence
↓
practice
↓
greater confidence

Because this process of change is important, 自信を持つ is very natural.

When Should You Use Each Expression?

Describing your current ability: 自信がある

When you want to explain what you are good at or what you believe you can do well, 自信がある is commonly used.

「パソコンの操作には自信があります。」
I’m confident in my computer skills.

「料理には自信があります。」
I’m confident in my cooking.

「人と話すことには自信があります。」
I’m confident when it comes to talking with people.

These sentences describe the speaker’s current level of confidence.

This pattern is especially common in introductions, job interviews, school situations, and conversations about personal strengths.

Encouraging someone: 自信を持つ

自信を持つ is especially common when giving encouragement.

「あなたの日本語は上手ですよ。もっと自信を持ってください。」
Your Japanese is good. Have more confidence in yourself.

Here, the speaker wants the other person to believe in their own ability.

Other natural examples include:

「自信を持って話してください。」
Please speak with confidence.

「自信を持って試験を受けてください。」
Go into the exam with confidence.

「自分の考えに自信を持ちましょう。」
Let’s have confidence in our own ideas.

These sentences focus on attitude and behavior rather than simply describing a current state.

Describing growth or change: 自信を持つ

自信を持つ is also useful when someone becomes more confident through experience, practice, or success.

「毎日会話を練習したことで、自信を持って日本語を話せるようになりました。」
By practicing conversation every day, I became able to speak Japanese with confidence.

The important point here is the change from being less confident to being more confident.

Examples of 自信がある

Example 1

「私は料理には自信があります。」
I’m confident in my cooking.

The speaker believes that their cooking ability is good. This describes their current state.

Example 2

「今回の試験にはかなり自信があります。」
I’m quite confident about this exam.

The speaker believes that they performed well or are likely to achieve a good result.

Example 3

「彼は自分の判断に自信があるようです。」
He seems confident in his judgment.

This describes how strongly he believes in his own judgment.

Example 4

「人前で話すことにはあまり自信がありません。」
I’m not very confident about speaking in front of people.

The speaker is describing an area in which they currently lack confidence.

Examples of 自信を持つ

Example 1

「もっと自信を持って話してください。」
Please speak with more confidence.

The speaker is encouraging the listener to believe in themselves more.

Example 2

「毎日練習を続けたことで、少しずつ自信を持てるようになりました。」
By practicing every day, I gradually became more confident.

The sentence emphasizes a change that happened through practice.

Example 3

「自分の考えに自信を持つことも大切です。」
It is also important to have confidence in your own ideas.

The focus is on maintaining a confident attitude toward your own thinking.

Example 4

「先生に褒められてから、自信を持って発表できるようになりました。」
After my teacher praised me, I became able to give presentations with confidence.

The praise caused a change in the speaker’s attitude.

A Common Point of Confusion: 自信がある vs 自信を持っている

You may also encounter 自信を持っている (jishin o motte iru / to have confidence).

Compare these sentences:

「彼は自分の技術に自信がある。」
He is confident in his skills.

「彼は自分の技術に自信を持っている。」
He has confidence in his skills.

Both sentences are natural, and their meanings are very close.

自信がある describes the state of confidence more directly.

自信を持っている comes from 自信を持つ and can place slightly more focus on the person’s attitude of believing in their own ability.

In many everyday situations, however, the difference is small.

For JLPT learners, the important point is not to assume that the two expressions always have completely different meanings. Instead, look at what the whole sentence emphasizes.

Common Mistakes

Incorrect: 自信をある

A common learner mistake is:

「私は日本語に自信をあります。」

This is incorrect.

Use:

「私は日本語に自信があります。」
I’m confident in my Japanese.

You can also say:

「私は日本語に自信を持っています。」
I have confidence in my Japanese.

The grammatical patterns are:

「自信がある」

and

「自信を持つ」

Do not mix がある and を持つ into one structure.

Encouragement usually requires 自信を持つ

Consider:

「あなたはもっと自信があります。」

This sounds unnatural if the intended meaning is “You should be more confident.”

A much more natural sentence is:

「もっと自信を持ってください。」
Please have more confidence in yourself.

Why?

自信があります describes a state.

自信を持ってください asks someone to adopt or develop an attitude.

When you see encouragement, advice, or a request for change, 自信を持つ is therefore often the better choice.

How to Tell Them Apart on the JLPT

On the JLPT, simply memorizing an English translation is often not enough.

You need to look at what is happening in the sentence.

Current state or ability → 自信がある

Consider:

「田中さんは長年海外で働いているので、英語にはかなり＿＿＿。」

Tanaka has worked overseas for many years, so he is quite ______ in his English.

The sentence describes his current confidence based on experience.

「自信がある」
is a natural choice.

Encouragement or advice → 自信を持つ

Consider:

「発音はとても上手ですよ。もっと＿＿＿話してください。」

Your pronunciation is very good. Please speak with more ______.

Here, the speaker is encouraging someone.

「自信を持って」
is natural.

A change expressed by ～ようになる → 自信を持つ

Consider:

「練習を続けた結果、人前でも自信を＿＿＿話せるようになった。」

As a result of continued practice, I became able to speak confidently even in front of people.

The phrase 話せるようになった shows a change.

Therefore:

「自信を持って」
fits naturally.

A Quick JLPT Strategy

If you are unsure which expression to choose, ask yourself:

• Is the sentence describing someone’s current state? → 自信がある
• Is someone being encouraged? → 自信を持つ
• Is the person becoming more confident? → 自信を持つ
• Is the sentence describing something someone is good at? → 自信がある
• Do you see words such as もっと or ～ようになる? → 自信を持つ is often likely

Do not focus only on the word 自信.

Look at the verbs and expressions around it. They often tell you whether the sentence is describing a state or a change in attitude.

Summary

自信がある and 自信を持つ both relate to confidence, but they focus on different aspects.

• 自信がある = confidence already exists; it describes a state
• 自信を持つ = to have, develop, or consciously show confidence; it often focuses on attitude or change

Compare:

「私は日本語に自信があります。」
I’m confident in my Japanese.

This describes the speaker’s current state.

「もっと自信を持って日本語を話しましょう。」
Let’s speak Japanese with more confidence.

This encourages a change in attitude or behavior.

At JLPT N3–N2 level, knowing the dictionary meaning of a word is only the first step. You also need to recognize which expression sounds natural in a particular context.

RJT (Rapid Japanese Training) helps you practice exactly this kind of decision-making through multiple-choice Japanese questions. By repeatedly choosing between similar expressions in context, you can build the ability to recognize the natural answer quickly instead of relying only on memorized translations.

If you often think, “I know what both choices mean, but I still don’t know which one to choose,” try practicing with real question patterns on RJT.
