働く vs 勤める vs 勤務する vs 仕事をする: The Difference Between Working, Being Employed, Working at a Company, and Doing Work in Japanese

Imagine you’re writing a Japanese self-introduction for a language class. You want to say “I work at a company,” so you write: 会社（かいしゃ）で勤めています. Your teacher circles the particle and writes に above it. But why? Isn’t で the particle for places?

This is one of the most common and most instructive mistakes Japanese learners make — and it points to something important. Japanese has four verbs that all translate roughly as “to work” in English: 働く（はたらく）, 勤める（つとめる）, 勤務する（きんむする）, and 仕事をする（しごとをする）. They are not interchangeable. Each one focuses on a different aspect of work — the activity, the employment relationship, the formal duty, or the task at hand — and each one triggers different particles and registers.

This guide breaks down exactly what each verb means, when to use it, which particle goes with it, and what mistakes to avoid. By the end, you’ll know exactly which “work” word to reach for — whether you’re writing a resume, chatting with a friend, or introducing yourself at a Japanese company.

What Does 働く Mean?

働く as the Activity of Working

働く（はたらく）is the most fundamental “work” verb in Japanese. It describes the act of working itself — the physical or mental labor you perform. Think of it as the verb of action: your body and mind are engaged in productive effort. It carries no inherent claim about who employs you or what your job title is. A factory worker, a freelance designer, a farmer, and a student working a part-time job all 働く.

The key particle is で, which marks the location where the action takes place.

会社で働く vs 会社に働く — Why で Is Correct

This is the core particle rule for 働く: the place where you perform work is marked with で, not に. The particle で indicates the site of an action. Since 働く describes the activity of working, the location naturally takes で.

会社に働く is grammatically awkward because に implies destination or affiliation rather than the site of an action. You’ll sometimes see に used with 働く in older or poetic Japanese, but in modern standard Japanese, で is the natural choice.

在宅で働く — Working from Home

One practical modern use: 在宅（ざいたく）で働く means “to work from home.” 在宅 literally means “being at home,” and で marks it as the location of the work activity. This is natural everyday language you’ll hear in conversation.

フリーランスとして働く — Working as a Freelancer

When you describe your role or capacity rather than your location, use として (as / in the role of) with 働く. フリーランスとして働く means “to work as a freelancer.” This pattern is very useful for self-introductions when you don’t work for a specific organization.

Common Example Sentences with 働く

彼（かれ）はレストランで働いています。
He works at a restaurant. (activity focus — that’s where he’s laboring)

毎日（まいにち）よく働く人（ひと）ですね。
You’re someone who works really hard every day.

私（わたし）はフリーランスとして東京（とうきょう）で働いています。
I work in Tokyo as a freelancer.

在宅で働くのが好きです。
I like working from home.

将来（しょうらい）、海外（かいがい）で働きたいです。
In the future, I want to work abroad.

What Does 勤める Mean?

勤める as an Employment Relationship

勤める（つとめる）shifts the focus from the activity of working to the employment relationship. When you use 勤める, you are saying that you are affiliated with, employed by, or serving within an organization. The emphasis is not on what you are doing moment to moment, but on who you belong to professionally.

The key particle is に, which here marks the organization as the destination of your affiliation — the place you are attached to.

会社に勤める — Working FOR a Company

会社に勤める means “to be employed by a company” — you are a member of that company’s workforce. The particle に shows that the company is the entity you are tied to. This is the standard way to state your employer in a self-introduction or on a resume.

Compare this directly with 会社で働く: the first emphasizes the employment relationship (you are the company’s employee), while the second emphasizes the place where work activity happens (you work there).

銀行に勤めています — I Work at a Bank

This is one of the most natural self-introduction patterns in Japanese. 銀行（ぎんこう）に勤めています is a complete, natural sentence meaning “I work at a bank” with the implication that you are employed there — you are a bank employee. It’s slightly more formal and organizational-sounding than 銀行で働いています.

公務員として勤める — Serving as a Civil Servant

Just like 働く, you can combine 勤める with として to describe your role. 公務員（こうむいん）として勤める means “to work / serve as a civil servant.” The use of 勤める here subtly implies a formal position within a public organization.

勤め先 — Your Employer / Workplace

A very useful compound: 勤め先（つとめさき）means “one’s employer” or “one’s workplace.” You’ll encounter this on forms that ask where you work. 勤め先はどこですか？ means “Where do you work?” (i.e., who is your employer?).

Common Example Sentences with 勤める

彼女（かのじょ）は大手（おおて）の商社（しょうしゃ）に勤めています。
She works at a major trading company. (she is employed there)

私の父（ちち）は市役所（しやくしょ）に勤めています。
My father works at the city office.

勤め先の名前（なまえ）を教えてください。
Please tell me the name of your employer.

彼は10年間（じゅうねんかん）、同（おな）じ会社に勤めています。
He has been working at the same company for 10 years.

公務員として市に勤めることになりました。
I have come to work for the city as a civil servant.

What Does 勤務する Mean?

勤務する as Formal Employment / Being on Duty

勤務する（きんむする）is the formal register equivalent of being at work or performing one’s official duties. You will rarely hear this in casual conversation between friends. Instead, you encounter it in employment contracts, HR documents, official schedules, formal announcements, and written reports. It has a bureaucratic, institutional flavor.

Think of 勤務する as the word a company uses to describe its employees’ official work status — as opposed to the word the employee uses to describe themselves.

勤務時間 — Working Hours

勤務時間（きんむじかん）is “working hours” or “hours of service.” You’ll see this on job postings, HR documents, and employee manuals. For example: 勤務時間は9時から18時までです (Working hours are from 9:00 to 18:00).

勤務地 — Work Location

勤務地（きんむち）means “place of work” or “work location” — the site where an employee is officially assigned. It appears constantly on job application forms and contracts. 勤務地：東京都内 means “Work location: within Tokyo.”

在宅勤務 — Remote Work / Working from Home

在宅勤務（ざいたくきんむ）is the formal compound for “remote work” or “work from home.” It became extremely common after 2020. Notice how this uses 勤務 rather than 働く — because it typically appears in official company communications and HR policy. Compare with 在宅で働く, which is more casual conversation.

Business and HR Example Sentences with 勤務する

現在（げんざい）、大阪（おおさか）支社（ししゃ）に勤務しております。
I am currently assigned to / working at the Osaka branch. (formal/written)

勤務時間は週（しゅう）40時間です。
The working hours are 40 hours per week.

勤務地は東京本社（とうきょうほんしゃ）となります。
The work location will be the Tokyo head office.

週3日（しゅうみっか）、在宅勤務が可能（かのう）です。
Remote work is possible 3 days a week.

夜勤（やきん）で勤務するスタッフを募集（ぼしゅう）しています。
We are recruiting staff to work night shifts.

What Does 仕事をする Mean?

仕事をする as “Do Work” or “Do a Task”

仕事をする（しごとをする）is the broadest of the four expressions. 仕事（しごと）means “work,” “job,” or “task,” and をする means “to do.” Together they form a general, flexible phrase meaning “to do work,” “to work,” or “to do one’s job.” Unlike the other three verbs, this is a noun + する construction, which makes it more versatile — you can modify 仕事 with adjectives and make nuanced statements.

It’s also the most common in casual conversation for describing working on any given day.

今日は仕事をします — “I Have Work Today”

今日（きょう）は仕事をします is a very natural, everyday sentence: “I have work today” or “I’m working today.” This is conversation-level language — exactly what you’d say to a friend who asks what you’re doing. You wouldn’t use 勤務する here.

いい仕事をする — Do a Good Job

Because 仕事 is a noun, you can describe the quality or type of work. いい仕事をする means “to do good work” or “to do a great job.” 丁寧（ていねい）な仕事をする means “to do careful / attentive work.” This flexibility is one reason 仕事をする is so common in daily speech.

仕事ができる — Capable / Skilled at Work

This is a fixed expression worth memorizing: 仕事ができる（しごとができる）means “to be capable at work” or “to be good at one’s job.” 彼は仕事ができる人です means “He’s someone who is really capable / competent at work.” This is a compliment in a professional context. Be careful — it does not mean “I can do work right now” (which would be 今、仕事ができます).

Common Example Sentences with 仕事をする

今日は家（いえ）で仕事をします。
I’m doing work at home today.

週末（しゅうまつ）も仕事をすることが多い。
I often end up working on weekends too.

もっと丁寧な仕事をしてください。
Please do more careful work / take more care with your work.

彼女は仕事ができる人として知られています。
She is known as someone who is very capable at work.

今日は仕事がたくさんあります。
I have a lot of work today.

働く vs 勤める

Activity vs Employment Relationship

The clearest way to understand the difference between these two: 働く describes what you are doing (performing labor), while 勤める describes your relationship to an organization (being employed there). You can 働く without having any employer — a freelancer or self-employed person 働く but may not 勤める anywhere. An office worker 勤める at a company and also 働く at that company — but the nuances are distinct.

会社で働く vs 会社に勤める — The Particle Difference

This is the most important practical distinction to internalize:

会社で働く — working AT the company (focus: the action of labor is happening at this place)
会社に勤める — working FOR the company (focus: you are an employee affiliated with this organization)

Both are correct in the right context. But if someone asks あなたの職業（しょくぎょう）は？ (What is your occupation?) or どこに勤めていますか？ (Where do you work?), the expected answer uses 勤める + に. A self-introduction says ○○会社に勤めています, not ○○会社で勤めています.

フリーランスとして働く (Works — No Employer)

A freelancer or self-employed person naturally uses 働く because there is no organization to 勤める at. フリーランスとして働く is the standard phrasing. Saying フリーランスとして勤める is unusual and sounds odd — 勤める implies an institutional employer.

公務員として勤める (Works For — Government)

By contrast, a civil servant works for a public institution and 勤める is perfectly natural: 市役所に勤める (to work at the city office). The institutional affiliation is exactly what 勤める expresses.

Common Particle Mistake

❌ 会社で勤めています → wrong particle for 勤める
✅ 会社に勤めています → correct
✅ 会社で働いています → correct (different verb, different focus)

Yuka

So if I want to say “I work at a hospital,” do I say 病院で働いています or 病院に勤めています?

Rei

Both are correct, but they say different things. 病院で働いています focuses on the activity — you perform your work at the hospital. 病院に勤めています says you are employed by the hospital as an organization. In a self-introduction, 病院に勤めています sounds more natural and professional.

勤める vs 勤務する

Everyday Employment Language vs Formal Register

勤める and 勤務する cover similar semantic ground — both describe being employed at an organization — but they differ sharply in register. 勤める is the natural, everyday word that any Japanese speaker would use in conversation. 勤務する belongs to formal written contexts: job postings, HR handbooks, contracts, and official communications.

Using 勤務する in casual conversation sounds stiff and overly formal — like saying “I am currently executing my professional duties at said financial institution” instead of “I work at a bank.”

銀行に勤める (Conversational) vs 銀行に勤務する (More Formal/Official)

Both sentences are grammatically correct:
銀行に勤めています — natural in conversation, self-introductions, ordinary descriptions of your job
銀行に勤務しております — formal written Japanese, official reporting, business correspondence (note: often uses the humble おります)

勤務先 / 勤務時間 / 勤務地 — Compound Vocabulary

勤務 appears in many useful compound words that you’ll see on Japanese forms and job listings:

• 勤務先（きんむさき）— one’s workplace / employer (on official forms; compare with 勤め先 which is slightly more casual)
• 勤務時間（きんむじかん）— working hours
• 勤務地（きんむち）— assigned work location
• 勤務形態（きんむけいたい）— work arrangement / employment type (full-time, part-time, etc.)
• 在宅勤務（ざいたくきんむ）— remote work / working from home

Resume and Contract Language

On a Japanese resume (履歴書（りれきしょ）), you will not write 「銀行で働きました」 — that is too casual. The standard form uses 勤める or lists the company name with 入社（にゅうしゃ）/退社（たいしゃ）patterns. But in job postings, you will frequently see 勤務 compounds: 勤務地・勤務時間・勤務形態 are standard job ad fields. Recognizing this vocabulary will help you read job listings in Japan.

Yuka

I keep seeing 勤務地 and 勤務時間 on Japanese job websites. Is it okay to use 勤務する in my cover letter?

Rei

Yes, in a formal cover letter or job application, 勤務する fits perfectly. You might write: 現在、○○社に勤務しております。 That said, in a conversational self-introduction at a job interview, 勤めています is also natural and slightly warmer.

働く vs 仕事をする

General Labor Activity vs Doing Specific Work or Tasks

働く focuses on labor as an activity — you are in a working state, expending effort. 仕事をする is more task-oriented — you are doing work, completing tasks, or engaged in a job. The distinction is subtle, but it becomes clearer in context:

Working hard in general → よく働く
Doing work / getting things done → 仕事をする

よく働く人 (A Hardworking Person)

よく働く人 is a natural, idiomatic expression for a hardworking person — someone who labors diligently. You would not say よく仕事をする人 as naturally for this nuance. 働く captures the idea of earnest, continuous effort.

週末に仕事をする (Doing Work on Weekends)

For specific instances of doing work — especially on a particular day or for a task — 仕事をする is more natural. 週末（しゅうまつ）に仕事をする means “to do work on the weekend.” You could say 週末に働く too, but 仕事をする feels more task-focused and is more commonly heard in conversation.

Natural Usage Examples

彼はよく働く。
He works hard / He is a hard worker. (general character trait)

今日は仕事をしたくない気分だ。
I don’t feel like doing work today. (task/activity focus)

いつまでも働き続けるのは大変だ。
It’s tough to keep working without end. (labor as activity)

もう少し仕事をしたら帰ります。
I’ll head home once I finish up a bit more work. (task-focused)

Particle Patterns Summary

で + 働く (Working AT a Place — Action Focus)

The particle で marks the location where an action takes place. Since 働く is an action verb describing labor, the site of that labor takes で. This is about where the work activity happens.

東京で働く / カフェで働く / 工場（こうじょう）で働く

に + 勤める (Employed BY an Organisation — Affiliation)

The particle に marks the organization as the target of your professional affiliation — the entity you are attached to as an employee. 勤める is not primarily an action verb; it expresses a state of being employed somewhere.

会社に勤める / 銀行に勤める / 学校（がっこう）に勤める

に / で + 勤務する (Assigned To / Stationed At)

勤務する can take either に (assigned to an organization: 本社に勤務する) or で (stationed at a location: 海外で勤務する). In practice, に is more common when the object is an institution or department; で appears when emphasizing the geographic location of duty.

Side-by-Side Particle Comparison Table

Common Mistakes English Speakers Make

Using 会社で勤める Instead of 会社に勤める

This is the most frequent mistake. English speakers naturally reach for a location particle (で) because “at” in “I work at a company” suggests location. But 勤める is about employment affiliation, not where the action happens, so it takes に. Always pair 勤める with に when naming your employer.

❌ 会社で勤めています
✅ 会社に勤めています

Using 勤務する in Casual Conversation

If your Japanese friend asks where you work and you reply 現在、○○社に勤務しております, they will probably smile politely but find it very formal — like reading from an official document. In casual conversation, use 勤めています or 働いています.

Translating Every “Work” as 働く

Because 働く is often the first “work” verb taught to beginners, many learners use it for every situation. But in a self-introduction, どこに勤めていますか is the natural question, and ○○会社に勤めています is the natural answer. Using 働く here is not wrong, but it sounds less precise and slightly less natural for stating your employer.

Missing 勤め先 for “My Employer / Workplace”

English speakers often try to express “my workplace” as 私の仕事場 or 私の会社, which can work but may sound awkward depending on context. The natural word on most Japanese forms and in many situations is 勤め先 — learn this word and use it.

Confusing 在宅で働く and 在宅勤務

Both refer to working from home, but 在宅勤務 is the formal compound (used in company communications and HR documents), while 在宅で働く is conversational. Saying 我が社では在宅で働くを導入（どうにゅう）します in an official announcement sounds odd — 在宅勤務を導入します is the correct, natural form in that register.

Not Knowing 仕事ができる Means “Capable / Skilled”

仕事ができる is a fixed expression meaning “capable at work” or “skilled professionally.” It is not the same as 仕事をすることができる (to be able to do work = to be available to work). If a colleague describes someone as 彼は本当に仕事ができる, they mean he is highly competent — not that he is physically capable of performing tasks.

Yuka

This is so helpful! I finally get why my teacher corrected 会社で勤める to 会社に勤める. 勤める is about affiliation, so it takes に instead of で. And I should save 勤務する for formal writing.

Rei

Exactly right! And remember: if you’re a freelancer with no employer, 働く is your go-to since 勤める implies belonging to an organization. Each verb has its own focus — activity, affiliation, formal duty, or task — and once you see that, the particles and contexts all make sense.

Decision Rule: Which Work Verb Should You Use?

Are You Describing the Activity of Working?

If you want to say that work is happening — that someone is performing labor at a place — use 働く. The focus is on the act. Particle: で + place.

Are You Saying Who You Are Employed By?

If you want to state your employer or organizational affiliation — who you work for — use 勤める. Particle: に + organization name.

Is This a Formal / HR / Contract Context?

If the context is a job posting, employment contract, official document, or formal written communication, use 勤務する. Also use it for 勤務地, 勤務時間, 在宅勤務 compounds.

Are You Describing Doing a Task or Doing Work Today?

For casual, task-focused statements — “I have work today,” “I’m doing work from home,” “do a good job” — use 仕事をする. It’s the most flexible and conversational of the four.
