Looking Up Information or Searching for Something?

Introduction

The Japanese verbs 調べる (shiraberu / to look up, investigate, or examine) and 探す (sagasu / to search or look for) can be confusing because both involve trying to find something you do not currently have.

This often leads Japanese learners to think:

Don’t both words mean “to look for” or “to find out”?

They do overlap in some situations, but their main purposes are different.

調べる (shiraberu) is used when you want to obtain information, check facts, or understand something in detail.

探す (sagasu) is used when you want to find a person, object, place, job, opportunity, or another specific target.

Because the meanings are close, using the wrong word will not always make your sentence impossible to understand. However, it can make otherwise correct Japanese sound slightly unnatural.

Let us begin with mistakes that Japanese learners often make.

Common Mistakes

Consider the following sentence:

インターネットで日本の歴史を探しました。
I searched for Japanese history on the internet.

The meaning is understandable, but the sentence sounds slightly unnatural if your goal was to learn about Japanese history.

A more natural sentence is:

インターネットで日本の歴史を調べました。
I looked up information about Japanese history on the internet.

Here is another common mistake:

なくした財布を一時間調べました。
I examined the wallet I had lost for an hour.

This sentence is also understandable, but it does not naturally express the idea of trying to find a missing wallet.

The natural expression is:

なくした財布を一時間探しました。
I looked for my lost wallet for an hour.

Both 調べる and 探す describe actions that bring you closer to an answer or a target. The important difference is what you are trying to obtain.

Why Do These Sentences Sound Unnatural?

The difference becomes easier to understand when you think about the desired result of the action.

The purpose of 調べる (shiraberu) is to obtain information or confirm facts.

For example, you can 調べる:

• the meaning of a word
• a train schedule
• the cause of an accident
• the price of a product
• information about history or culture

In these situations, you are not trying to find the object itself. You are trying to learn information about it.

The purpose of 探す (sagasu), on the other hand, is to find the person, object, place, opportunity, or option that you need.

For example, you can 探す:

• a lost key
• a hotel near a station
• a suitable job
• a person you want to meet
• a book you want to read

A useful way to remember the difference is:

• Use 調べる when you want to know or confirm information.
• Use 探す when you want to find a person, object, place, or suitable option.

When learners overlook this difference in purpose, they may produce slightly unnatural combinations such as 日本の歴史を探す or 財布を調べる.

Natural Corrections

Let us correct the earlier examples.

Mistake 1

インターネットで日本の歴史を探しました。
I searched for Japanese history on the internet.

Natural Expression

インターネットで日本の歴史を調べました。
I looked up information about Japanese history on the internet.

In this sentence, the speaker is not trying to find Japanese history itself.

The goal is to read information and learn more about Japanese history. Therefore, 調べる is the natural choice.

However, 探す is correct in the following sentence:

インターネットで日本の歴史について書かれた本を探しました。
I searched online for a book about Japanese history.

Here, the specific target is a book. Because the speaker wants to find that book, 探す is natural.

Mistake 2

なくした財布を一時間調べました。
I examined the wallet I had lost for an hour.

Natural Expression

なくした財布を一時間探しました。
I looked for my lost wallet for an hour.

The speaker does not want to obtain information about the wallet. The goal is to find the missing wallet itself.

That is why 探す is used.

However, 調べる can be used with 財布 when someone examines its contents or condition.

警察は、見つかった財布の中身を詳しく調べました。
The police carefully examined the contents of the wallet that had been found.

Even when the same noun appears, the correct verb changes depending on whether the purpose is to find the item or examine it.

The Basic Difference Between 調べる and 探す

What Does 調べる Mean?

調べる (shiraberu / to look up, investigate, examine, or check) means gathering information or checking details in order to understand something more clearly.

It is often used when you consult books, dictionaries, websites, records, or other information sources.

It is also used when doctors, police officers, researchers, or other professionals investigate a condition or cause.

言葉の意味を辞書で調べる。
Look up the meaning of a word in a dictionary.

病気の原因を調べる。
Investigate the cause of an illness.

電車の出発時間を調べる。
Check the train’s departure time.

The important question is:

What information do you want to know?

What Does 探す Mean?

探す (sagasu / to search or look for) means trying to find something that is missing or something that meets your needs.

It can be used for people and physical objects, as well as jobs, homes, methods, opportunities, and solutions.

なくした鍵を探す。
Look for a lost key.

新しい仕事を探す。
Look for a new job.

静かに勉強できる場所を探す。
Look for a quiet place to study.

The important question is:

What do you want to find?

An Easy Way to Remember

When you are unsure which verb to use, ask yourself:

Do I want to know more, or do I want to find something?

Use 調べる when you want to know or confirm information.

Use 探す when you want to find a person, object, place, or suitable option.

Learn the Difference Through Examples

Example 1

分からない漢字の読み方を辞書で調べました。
I looked up the reading of an unfamiliar kanji in a dictionary.

The speaker wants to obtain information about how the kanji is read. Therefore, 調べる is natural.

Example 2

図書館で日本語の文法書を探しました。
I looked for a Japanese grammar book in the library.

The speaker wants to find a particular type of book. Therefore, 探す is used.

Example 3

旅行の前に、京都の天気を調べておきます。
I will check the weather in Kyoto before the trip.

The speaker is confirming weather information, so 調べる is natural.

Example 4

京都で安く泊まれるホテルを探しています。
I am looking for an inexpensive hotel in Kyoto.

The speaker wants to find a hotel that meets a particular condition. Therefore, 探す is used.

Example 5

この商品の値段をインターネットで調べました。
I checked the price of this product online.

The speaker is checking price information. Therefore, 調べる is natural.

Example 6

もっと安い商品を探して、いくつかの店を回りました。
I visited several stores looking for a cheaper product.

The goal is to find a product that is cheaper. Therefore, 探す is the correct verb.

Example 7

医師が痛みの原因を詳しく調べています。
The doctor is carefully investigating the cause of the pain.

The doctor is examining the condition and trying to identify its cause. Therefore, 調べる is used.

Example 8

医師を探しています。
I am looking for a doctor.

The speaker wants to find a doctor who can provide treatment, or perhaps locate a particular doctor. Therefore, 探す is natural.

When Both Words Seem Possible

There are situations in which both 調べる and 探す can be used, but the focus changes.

Compare the following sentences:

留学できる学校を調べています。
I am researching schools where I can study abroad.

留学できる学校を探しています。
I am looking for a school where I can study abroad.

学校を調べています focuses on checking information such as location, tuition, courses, admission requirements, and school reputation.

学校を探しています focuses on finding a suitable school to attend.

The noun is the same, but the speaker’s purpose is different.

Now compare these sentences:

新しい仕事について調べています。
I am researching new types of work or job opportunities.

新しい仕事を探しています。
I am looking for a new job.

仕事について調べる means checking information such as job responsibilities, qualifications, salaries, or working conditions.

仕事を探す means trying to find an actual job to apply for.

The particles can also help you notice the difference:

• 仕事について調べる
  Research information about a job.

• 仕事を探す
  Look for a job.

Learning these common patterns will help you choose the natural verb more quickly.

Common JLPT Traps

In JLPT vocabulary and reading questions, 調べる and 探す may appear together as answer choices.

Consider the following question:

明日の電車の時間をインターネットで＿＿＿。
I checked tomorrow’s train schedule on the internet.

• 探した
• 調べた
• 拾った
• 見つめた

The correct answer is 調べた.

The speaker is not trying to find the train itself. The speaker is checking information about its departure time.

Now consider another question:

駅でなくした傘を＿＿＿が、見つからなかった。
I looked for the umbrella I had lost at the station, but I could not find it.

• 調べた
• 探した
• 確かめた
• 数えた

The correct answer is 探した.

The speaker is trying to find the missing umbrella itself, not gather information about it.

On the JLPT, two words may seem close when you only look at their dictionary meanings. The surrounding context shows which action is required:

• checking or obtaining information
• finding a person, object, place, or suitable option

Also, do not assume that インターネットで automatically requires 調べる.

インターネットで近くのレストランを探しました。
I searched online for a nearby restaurant.

In this sentence, the goal is to find a restaurant that meets the speaker’s needs. Therefore, 探す is natural.

Do not choose the verb based only on the tool or location being used. Focus on the final purpose of the action.

Summary

調べる and 探す both describe actions related to something unknown, but their purposes are different.

• 調べる is used when you check information, facts, details, conditions, or causes.
• 探す is used when you try to find a person, object, place, job, opportunity, or suitable option.
• Use 調べる when your goal is to know more.
• Use 探す when your goal is to find something.

To master similar Japanese words, do not memorize only their translations. Pay attention to what the speaker wants to achieve in the sentence.

Words with similar meanings frequently appear in JLPT vocabulary and reading questions. Reading explanations is helpful, but solving many contextual questions is the best way to develop a natural sense of which word fits.
