Explicação 依頼 in your Level:

At the A1 level, you don't need to use 'irai' (依頼) in your own speech yet, but you might see it in simple contexts like a 'Quest' in a video game or a 'Request Form' at a school or office. Think of it as a very polite way to say 'Please do this for me' in a professional setting. If you see '依頼する' (irai suru), it means someone is asking for help or a service. It is a 'big' word for a 'big' favor. Most of the time, you will use 'Onegai shimasu' instead, but knowing 'irai' helps you understand when a situation is formal. For example, if a teacher gives you a special task, they might call it an 'irai'. You can remember it as 'I + Rely' (I rely on you to do this). At this stage, focus on recognizing the kanji and the fact that it involves two people: one who asks and one who performs the task.

As an A2 learner, you should start recognizing 'irai' in business or formal environments. You might see it on a website button that says 'Contact/Request' (お問い合わせ・ご依頼). At this level, you can start using 'irai suru' when talking about hiring someone or asking for a professional service. For example, 'I requested a repair' (Shuuri wo irai shimashita). It's important to differentiate this from 'tanomu' (to ask). While 'tanomu' is fine for friends, 'irai' makes you sound more professional when dealing with companies or strangers. You will also see it in the form 'Go-irai' (ご依頼), which is the polite version used by businesses when they talk to you. Learning this word helps you navigate formal Japanese society where 'onegai' might feel a bit too casual or childish for serious matters like legal work or technical services.

At the B1 level, you are expected to use 'irai' (依頼) correctly in professional emails and formal conversations. You should understand the common collocations such as 'irai wo ukeru' (to accept a request) and 'irai wo dasu' (to issue a request). This is the level where you distinguish between 'irai' and 'yousei' (official demand). You should be comfortable using 'irai' in a Suru-verb form to describe business transactions. For example, 'We requested a translation from that company' (Sono kaisha ni honyaku wo irai shimashita). You should also be aware of the noun form 'iraisho' (written request) and how it's used in office administration. This word is essential for anyone planning to work in a Japanese environment or deal with Japanese clients, as it sets the correct professional tone and establishes a clear boundary between personal favors and professional commissions.

By B2, you should master the nuances of 'irai' (依頼) and its related vocabulary. You should understand the subtle difference between 'irai' and 'itaku' (entrusting/outsourcing). 'Irai' is the act of requesting, while 'itaku' often refers to the legal or structural arrangement of the work. You should also be able to use honorifics correctly with 'irai', such as using 'go-irai' when referring to a client's request and 'irai moushiageru' in very formal humble speech. At this level, you can handle complex sentences like 'Upon receiving the request, we immediately began the investigation' (Irai wo uke, tadachi ni chousa wo kaishi shimashita). You should also recognize 'irai' in legal and journalistic contexts, where it might refer to formal petitions or the commissioning of expert testimony. Your usage should reflect an understanding of the social 'distance' and professional 'trust' (the 'rai' in irai) inherent in the word.

At the C1 level, your understanding of 'irai' (依頼) should be comprehensive, including its use in legal, academic, and high-level business Japanese. You should be able to discuss the ethics of 'irai' (e.g., conflict of interest in legal requests) and use the word in abstract contexts. You should be familiar with related terms like 'irai-shin' (a spirit of dependence), which has a slightly negative connotation of relying too much on others. You can use 'irai' to analyze social structures—for instance, how the 'irai' system in Japanese guilds differs from Western contracting. You should be able to use the word fluently in complex grammatical structures, such as passive-causative forms or within highly formal 'keigo' frameworks. Your ability to distinguish 'irai' from 'kon-gai' (earnest prayer) or 'chin-jou' (petition) based on the specific social and legal implications is a hallmark of this level.

At the C2 level, you possess a native-like grasp of 'irai' (依頼), including its historical development and its place in the Japanese legal and linguistic system. You understand the nuances of the kanji '依' (to depend) and '頼' (to trust) and can explain how this word reflects Japanese concepts of mutual obligation and professional reliance. You can use 'irai' in high-level literary or philosophical discourse, and you are aware of its use in archaic or highly specialized technical documents. You can navigate the most complex honorific exchanges involving 'irai' without hesitation, and you can identify when 'irai' is being used euphemistically or with irony. Your mastery allows you to use the word to negotiate complex professional relationships, recognizing the weight of the 'trust' being placed in the recipient of the 'irai'. You are also fully aware of the legal definitions of 'irai' in various contract laws and can use the term accurately in a court or board-room setting.

依頼 em 30 segundos

Irai means a formal or professional request, distinct from casual favors.
It is commonly used as a 'Suru-verb' (依頼する) to mean 'to commission' or 'to request'.
In business, it appears in phrases like 'go-irai' (your request) and 'iraisho' (request form).
It implies a level of trust (rai) and professional reliance (i) between two parties.

The Japanese word 依頼 (irai) is a fundamental noun that translates most accurately to 'request' or 'commission' in a formal or professional context. While the common word お願いおねがい (onegai) is used for everyday favors, irai carries a weight of formality, often implying a transaction, a professional engagement, or a serious appeal for assistance. It is the standard term used when a client asks a professional to perform a task, such as a lawyer taking a case or a designer creating a logo.

Professional Context: Used when hiring freelancers, consultants, or specialists. For example, 'design no irai' means a request for design work.
Formal Tone: It appears in business emails, contracts, and official announcements where 'onegai' would sound too casual or personal.
Legal and Official: Frequently used in legal documents to describe the act of retaining counsel or requesting official intervention.

弁護士に調査を依頼しました。(I requested an investigation from a lawyer.)

In Japanese society, where levels of politeness are strictly observed, knowing when to switch from 'onegai' to 'irai' demonstrates professional maturity. For instance, if you ask a colleague to pass a pen, you use 'onegai'. If you ask a translation agency to translate a manual, you use 'irai'. The kanji themselves are telling: 依い means 'depend on' or 'rely', and 頼らい means 'trust' or 'request'. Together, they represent an act of entrusting a task to someone based on their expertise or capability. This word is also extremely versatile as a 'Suru-verb' (依頼する), allowing you to describe the action of making the request directly.

新しいプロジェクトの依頼が来ました。(A request for a new project has arrived.)

Grammatical Flexibility: It can function as a noun (the request itself) or a verb when combined with 'suru'.

Understanding 'irai' is your gateway to professional Japanese. It signals that you are moving beyond basic survival Japanese into the realm of business and professional cooperation. Whether you are the one making the request (依頼者 - iraisha) or the one receiving it, this word frames the interaction as a serious, respectful exchange of services.

Using 依頼 (irai) correctly involves understanding its role as both a noun and a verb. In its noun form, it often takes the particle 'no' to modify other nouns or follows 'wo' when it is the object of an action. As a verb, 'irai suru' is the engine of professional communication.

Noun + 依頼: When you want to specify what kind of request it is, use [Topic] + [no] + 依頼. Example: 'Shuuri no irai' (Request for repair).
依頼 + する: This turns the noun into the action of requesting. 'Kare ni irai shita' (I requested [it] from him).

原稿の執筆を依頼されました。(I was requested to write a manuscript.)

When constructing sentences, pay attention to the particles. The person you are making the request *to* is usually marked with 'ni'. The task or object of the request is marked with 'wo'. If you are receiving a request, you might use 'irai wo ukeru' (to receive/accept a request). If you are turning one down, 'irai wo kotowaru' (to refuse a request) is the standard phrasing.

専門家に依頼するのが一番です。(It is best to request [help from] an expert.)

In business settings, you will often hear 'irai' used with humble or honorific verbs. For example, 'go-irai' (adding the polite prefix 'go') is used when referring to a request made by a client or superior. 'Go-irai arigatou gozaimasu' (Thank you for your request) is a standard opening line for customer support or freelance responses. Using 'irai' instead of 'onegai' in these situations immediately elevates your Japanese to a professional level.

急な依頼で申し訳ありません。(I am sorry for the sudden request.)

Common Verb Pairings: Irai wo dasu (To send out a request), Irai wo hikiukeru (To take on a request).

You will encounter 依頼 (irai) in a variety of real-world scenarios, ranging from corporate boardrooms to digital platforms. It is a staple of the Japanese working world. If you use services like CrowdWorks or Lancers (Japanese freelance platforms), the word 'irai' will be everywhere, as every job post is essentially a 'work request'.

クライアントからの依頼を確認します。(I will check the request from the client.)

In the world of entertainment, specifically anime and manga, 'irai' is a keyword in the 'mystery' or 'detective' genres. A classic scene involves a mysterious client walking into a detective agency and saying, 'Irai ga arimasu' (I have a request/case for you). Similarly, in fantasy settings, adventurers visit the 'Guild' to pick up 'irai' (quests) posted on a bulletin board. This usage highlights the word's connection to a specific task that requires a specialist's skill.

Business Emails: Subject lines often read: 【ご依頼】見積もりのお願い (Request: Quotation Request).
News and Media: Reports on government actions often use 'irai' for formal appeals to the public or international bodies.

今回の依頼内容は以下の通りです。(The details of this request are as follows.)

Finally, in daily administrative life, you might see 'irai' on forms at the city hall or bank. For example, a 'furikomi irai-sho' is a bank transfer request form. In these cases, it is purely functional, indicating a formal instruction given to an institution to perform a specific service. Whether it is a high-stakes legal case or a simple bank transfer, 'irai' is the word that bridges the gap between a need and a professional solution.

The most common mistake for English speakers is overusing 依頼 (irai) in casual situations. Because 'irai' is often translated as 'request', learners might think it's a direct synonym for 'ask'. However, using 'irai' when you should use 'onegai' can make you sound strangely robotic or overly formal, like you are trying to hire your friend to pass the salt.

Mistake: Casual Favors: Incorrect: 'Tomodachi ni mizu wo irai shita' (I commissioned my friend for water). Correct: 'Tomodachi ni mizu wo tanonda'.
Mistake: Confusing with 'Tanomu': 'Tanomu' is a verb that can be casual or formal. 'Irai' is strictly formal. Don't use 'irai' with close family members unless you're joking.

❌ 友だちに宿題を依頼した。
✅ 友だちに宿題を教えてと頼んだ。

Another mistake is failing to use the correct particles. Since 'irai' is a noun that becomes a verb with 'suru', learners sometimes forget the 'wo' or 'ni'. Remember: [Person] **ni** [Action] **wo** irai suru. If you omit 'ni', the sentence might imply you are requesting the person themselves, rather than requesting *from* them.

Lastly, don't confuse 'irai' (依頼) with 'irai' (以来). Although they are pronounced the same, '以来' means 'since' or 'henceforth'. Context usually makes the difference clear, but in writing, the kanji are completely different. If you write 'since yesterday' using the kanji for 'request yesterday', your sentence will make no sense!

To truly master 依頼 (irai), you must see how it fits into the broader landscape of Japanese words for 'asking' and 'requesting'. Depending on the level of formality and the nature of the request, you might choose a different term.

お願い (Onegai): The all-purpose word. Use this for everything from 'Please look at this' to 'I beg you'. It is softer and more personal than 'irai'.
要請 (Yousei): Even more formal than 'irai'. It implies an 'appeal' or a 'demand' for something necessary, often used by governments or organizations (e.g., 'emergency request').
注文 (Chuumon): Specifically for 'ordering' goods or services in a commercial sense (like at a restaurant or on Amazon).

依頼 vs 要請: 依頼 is a professional request; 要請 is a high-level demand or official appeal.

There is also 委託いたく (itaku), which means 'entrusting' or 'outsourcing'. While 'irai' is the act of asking, 'itaku' is the formal arrangement of handing over the responsibility. In a business contract, you might 'irai' a service, which results in an 'itaku' agreement.

Finally, consider 懇願こんがん (kongan), which means 'entreaty' or 'supplication'. This is used when the request is desperate or emotional. 'Irai' is cold and professional; 'kongan' is warm and pleading. Choosing the right word is about matching the emotional temperature of the situation.

How Formal Is It?

Curiosidade

The kanji for 'Rai' (頼) also appears in 'Tayori' (reliance/news). In ancient times, making a request was seen as an act of placing your trust entirely in another person's hands.

Como usar

frequency

Very common in professional, legal, and formal contexts. Essential for N3+ levels.

Erros comuns

Using 'irai' for passing a drink. → Mizu wo totte (tanomu).
'Irai' is for professional/formal tasks, not small physical favors.
Saying 'Irai wo suru' instead of 'Irai suru'. → Irai suru.
While 'wo suru' is grammatically okay, 'irai suru' is the more natural compound verb.
Confusing 'Irai' (Request) with 'Irai' (Since). → Check the kanji or context.
They sound the same but mean totally different things.
Using 'irai' with close family members. → Tanomu / Onegai.
It sounds weirdly cold and distant with family.
Forgetting the 'ni' particle for the person. → Tanaka-san NI irai suru.
The 'ni' shows who you are directing the request to.

Dicas

Business Etiquette

Always add 'go-' (ご依頼) when talking to a client about their request to show respect.

Nailing the Nuance

Think of 'irai' as 'commissioning' someone. It implies they have a skill you need.

Verb Forms

Remember it's a Suru-verb. 'Irai shimasu' is the polite present form.

Gaming Tip

If you play Japanese RPGs, look for the '依頼' (Quest) menu to find tasks.

Kanji Tip

Both kanji start with the 'person' radical. Requests are between people!

Trust Factor

The 'rai' in 'irai' is the same as in 'shinrai' (trust). A request is a sign of trust.

Avoid Dependency

Don't let people say you have 'irai-shin' (too much dependency). Be independent!

Pitch Check

Listen for the flat pitch to distinguish it from 'since' (以来).

Email Subject

Use 【ご依頼】 in your email subject to get a faster response for business.

Level Up

Mastering 'irai' marks your transition from 'survival Japanese' to 'professional Japanese'.

Memorize

Mnemônico

Think: 'I' + 'Rely'. 'I' (依) and 'Rai' (頼) both mean rely. So, I-Rai means 'I rely on you to do this professional job'.

Associação visual

Imagine a detective (like Sherlock Holmes) receiving a formal letter (an 'irai') from a mysterious client.

Word Web

Business Client Contract Request Professional Trust Expert Task

Desafio

Try to use 'irai suru' instead of 'tanomu' the next time you talk about hiring someone or getting a professional service like a haircut or a repair.

The word comes from Middle Chinese roots. '依' (I) means to lean on or rely on. '頼' (Rai) means to trust, rely on, or request.

Significado original: To rely on someone's trust to get a task done.

Sino-Japanese (Kango).

Contexto cultural

Be careful using 'irai-shin' (spirit of dependency) as it can be an insult, implying someone is lazy or lacks independence.

In English, we often just say 'I asked them to...' regardless of formality. In Japanese, 'irai' is a crucial level of formality that English lacks a single specific word for.

The 'Irai' board in the anime 'Fairy Tail'. Case files in 'Detective Conan' are often called 'irai'. Freelance sites like Lancers use 'irai' for job postings.

Usually no. It sounds too formal, like you are trying to hire them. Use 'tanomu' or 'onegai' instead.

It is a 'written request form'. Companies use them to formally document what they want someone to do.

It's close. It means to request a specific task. You might 'irai' a freelancer for one job, but 'yatou' (hire) an employee for long-term work.

In business, say 'Go-irai arigatou gozaimasu'.

It refers to a 'dependent mindset' where someone relies too much on others' help.

No, it's for tasks or services. You don't 'irai' a book; you 'chuumon' (order) it.

Yes, very often! Adventurers in RPG settings get 'irai' (quests) from guilds.

'Irai' is the act of asking; 'itaku' is the contract of outsourcing the work.

Use 'Irai wo okotowari suru' or 'Irai ni oujikane-masu'.

The first one (依) is easy, but the second one (頼) has many strokes. Practice it carefully!
