At the A1 level, you don't need to use '通知する' (tsuuchi suru) very often in your own speaking, but you will see it on your phone! When you use a Japanese app, you might see a button that says '通知' (Notification). Think of it as a special word for 'messages from your phone or computer.' At this stage, instead of saying 'tsuuchi suru,' you should use 'shiraseru' (to let someone know) or 'oshieru' (to tell/teach). For example, if you want to tell your teacher you will be absent, you 'shiraseru.' If your phone vibrates with a new message, that is a 'tsuuchi.' Just remember: 'Tsuuchi' is for machines and official things. 'Shiraseru' is for people. You might see it in simple phrases like '通知が来ました' (A notification came). This is a great way to start recognizing the word in your daily life in Japan or while using Japanese technology.
At the A2 level, you should begin to recognize '通知する' (tsuuchi suru) in more formal settings, such as school or work. You will see it in emails from your university or workplace. For example, '明日、テストの結果を通知します' (Tomorrow, I will notify you of the test results). You are learning that Japanese has different words for 'telling' depending on the situation. 'Tsuuchi suru' is used when the information is important and formal. You might also see '通知設定' (tsuuchi settei) in your phone settings, which means 'Notification Settings.' This is where you can turn sounds on or off. In your own writing, you can use 'tsuuchi suru' when writing a formal email to a group of people, but for one-on-one emails to friends, stick to 'renraku suru' (to contact). Understanding the difference between 'renraku' (casual/business contact) and 'tsuuchi' (formal notification) is a key part of moving to the next level.
At the B1 level, you are expected to use '通知する' (tsuuchi suru) correctly in business and formal writing. You should understand the grammatical structure: [Target] に [Information] を 通知する. You should also be comfortable with the passive form, '通知される' (tsuuchi sareru), which is very common in official documents. For example, '家賃の値上げが通知された' (I was notified of a rent increase). This level requires you to distinguish between 'tsuuchi' and other similar verbs like 'houkoku' (reporting progress) and 'kokuchi' (publicly announcing). You should use 'tsuuchi' when you are the one sending out official information, such as an organizer notifying participants of a schedule change. It is also important to know the noun form '通知' and how it combines with other words, like '通知書' (official notification document) or 'プッシュ通知' (push notification). This word is essential for navigating life in Japan, from understanding bank letters to following company procedures.
At the B2 level, you should have a nuanced understanding of '通知する' (tsuuchi suru) and its role in administrative and legal language. You will encounter it in contracts (e.g., '30日前に通知しなければならない' - must notify 30 days in advance) and in technical documentation for software development. You should be able to use it in complex sentences involving honorifics, such as 'お客様にメールにて通知させていただきます' (We will humbly notify the customer via email). At this stage, you should also recognize the difference between 'tsuuchi' and 'tsuutatsu' (administrative directives). You should be able to discuss the 'notification' features of an application or the legal requirements for notifying citizens about public works. Your vocabulary should also include related terms like '事前通知' (prior notification) and '事後通知' (subsequent notification). You are expected to use this word naturally in professional meetings when discussing how to communicate changes to clients or stakeholders.
At the C1 level, your mastery of '通知する' (tsuuchi suru) includes its use in highly specialized fields such as law, high-level administration, and software architecture. You should understand the legal implications of a 'tsuuchi'—how it serves as official proof that information was delivered. You will encounter this in discussions about the 'Notification Principle' in administrative law or the 'Observer Pattern' in programming where objects 'notify' each other of state changes. You should be able to critique the tone of various notifications, ensuring they meet the required level of formality or 'Keigo' (honorific language). You should also be familiar with archaic or highly formal variations like '通牒' (tsuuchou - a formal note or memorandum, often in diplomacy). In writing, you can use 'tsuuchi' to describe the dissemination of information in a sociological or organizational context, discussing how information flows through a hierarchy. Your use of the word should be precise, distinguishing it from 'shiji' (instructions) or 'kankoku' (recommendations).
At the C2 level, you possess a native-like command of '通知する' (tsuuchi suru), including its most subtle connotations and historical context. You can navigate the most complex legal statutes where 'tsuuchi' is defined and regulated, understanding the difference between 'effective notification' and 'actual receipt.' You can use the word in philosophical or academic discourse regarding communication theory, or in high-level business negotiations where the timing and method of notification can have significant financial or legal consequences. You are comfortable with the word in all its forms, from its use in automated API documentation to its appearance in classical-style formal announcements. You can effortlessly switch between 'tsuuchi' and its synonyms to achieve specific rhetorical effects, and you understand the cultural weight of receiving a 'tsuuchi' from various Japanese institutions. At this level, the word is not just a vocabulary item but a tool for precise, professional, and legally sound communication in any Japanese-speaking environment.

通知する در ۳۰ ثانیه

  • A formal verb meaning 'to notify' or 'to inform officially.'
  • Commonly used in business, government, and mobile app notifications.
  • Follows the grammar pattern: [Target] に [Information] を 通知する.
  • Essential for understanding official Japanese documents and system alerts.

The Japanese verb 通知する (つうちする - tsuuchi suru) is a cornerstone of formal and functional communication in Japan. At its core, it means 'to notify' or 'to formally inform.' While everyday words like 知らせる (shiraseru) cover general informing, tsuuchi suru carries a weight of officiality, precision, and often, a one-to-many or system-to-user relationship. It is the word you encounter when a government office sends a tax bill, when an app sends a push notification to your smartphone, or when an employer officially informs a candidate of their hiring status.

Etymology and Nuance
The word is composed of two kanji: 通 (tsuu), meaning 'to pass through' or 'communicate,' and 知 (chi), meaning 'to know.' Combined, they represent the act of making knowledge pass from one entity to another in a structured manner. Unlike 'renraku' (contact), which implies a two-way dialogue, 'tsuuchi' is often unidirectional—providing information that the recipient needs to be aware of for legal, administrative, or functional reasons.

合格者にはメールで結果を通知する予定です。(We plan to notify the successful candidates of the results via email.)

In the modern digital age, this word has found a permanent home in technology. Every 'notification' on your phone—be it a message, a low battery warning, or a software update—is referred to as a 通知 (tsuuchi). When you toggle settings in an app, you are often looking for the 通知設定 (tsuuchi settei - notification settings). This usage highlights the word's role in conveying specific data points or status changes that require the user's attention. Outside of tech, it remains vital in the 'Shinbun' (newspaper) and 'Houritsu' (law) domains, where official announcements of policy changes or court rulings are issued as formal notifications. Understanding this word requires recognizing that it is not just about 'talking'; it is about 'notifying' with a purpose and, usually, a paper or digital trail.

Formal Contexts
In business, 'tsuuchi suru' is used for official board decisions, layoff notices, or changes in terms of service. It implies that the information is final and has been processed through the correct channels.

新しい規約の変更をユーザーに通知する必要があります。(It is necessary to notify users of the changes to the new terms.)

Using tsuuchi suru correctly involves understanding its grammatical particles. Because it describes the act of delivering information to someone, it typically follows the pattern: [Person/Group] に [Information] を 通知する. The person being notified is marked with the indirect object particle に (ni), and the information or content of the notification is marked with the direct object particle を (wo).

Passive Construction
In many formal situations, the passive form 通知される (tsuuchi sareru) is used. This is common when the recipient is the subject of the sentence, particularly in bureaucratic contexts where the 'notifying entity' is an abstract organization like the government or a university. For example, 'I was notified of the results' becomes '結果が通知された' (kekka ga tsuuchi sareta).

採用の可否は、来週までに書面で通知されます。(The decision on hiring will be notified in writing by next week.)

Another important aspect is the medium of notification. This is often indicated by the particle で (de). Common mediums include メールで (by email), 書面で (in writing/by document), 電話で (by phone), or プッシュ通知で (via push notification). When writing business emails, you might see the noun form 通知 (tsuuchi) used as a heading, such as '採用結果のご通知' (Notification of hiring results), where the honorific 'go' is added to show respect to the recipient.

警報が発令されたことを住民に通知した。(We notified the residents that an alarm had been issued.)

Finally, consider the timing. Phrases like '事前に通知する' (to notify in advance) are extremely common in contracts and service agreements. This ensures that the recipient has enough time to prepare for the upcoming change or event. Conversely, '事後に通知する' (to notify after the fact) might be used in emergency situations where action had to be taken before informing the parties involved.

If you live in Japan or use Japanese software, tsuuchi suru is unavoidable. The most frequent encounter is likely your smartphone. Every time an app asks for permission to 'Send Notifications,' the prompt will use the word 通知. In the settings menu, you will see options like '通知を許可する' (Allow notifications) or '通知をオフにする' (Turn off notifications). This has made the word part of the daily lexicon for everyone from children to the elderly.

The Workplace
In a Japanese office, you will hear this word during HR announcements or IT system updates. If the company is changing its health insurance provider, the HR department will 'tsuuchi suru' all employees. If the server is going down for maintenance, the IT department will 'tsuuchi suru' the staff. It denotes a formal, non-negotiable dissemination of information.

会議の時間が変更になったら、すぐにメンバーに通知してください。(If the meeting time changes, please notify the members immediately.)

Another critical area is education and government. Students receive a 通知表 (tsuuchihyou), which is their report card. This 'notification table' is the official record of their grades. Similarly, when the Japanese government issues the 'My Number' card or tax assessments, these arrive as 通知書 (tsuuchisho) or notification documents. In these cases, 'tsuuchi' isn't just a message; it's a legal record. You also hear it in news broadcasts regarding international relations—for example, when one country 'notifies' another of its intent to withdraw from a treaty.

市役所から税金の支払いに関する通知が届いた。(A notification regarding tax payments arrived from the city hall.)

The most common mistake learners make with tsuuchi suru is using it in casual, interpersonal contexts where it feels too cold or robotic. For instance, if you want to tell a friend that you're going to be late for dinner, you should not say '遅れることを通知する' (I notify you that I will be late). This sounds like you are an automated bot or a very stern boss. Instead, use 連絡する (renraku suru) or 知らせる (shiraseru).

Confusing with 'Houkoku'
Another frequent error is confusing 'tsuuchi' with 報告 (houkoku - report). 'Houkoku' is generally upwards (subordinate to superior) and describes the progress or result of a task. 'Tsuuchi' is generally downwards or lateral and describes an official announcement or data delivery. You 'houkoku' your progress to your boss, but the company 'tsuuchi' the holiday schedule to you.

友達に私の新しい電話番号を通知した
友達に新しい電話番号を教えた。(I told my friend my new number.)

Grammatically, some learners forget the に (ni) particle for the recipient. Because 'tsuuchi suru' feels like 'sending,' people sometimes mistakenly use 'e' (direction), but 'ni' is the standard for the target person. Also, be careful with the noun form 'tsuuchi.' While 'tsuuchi' is the notification itself, 'tsuuchisho' is the physical or digital document. Using them interchangeably is usually fine, but in legal contexts, 'tsuuchisho' is more precise.

Finally, remember that 'tsuuchi suru' doesn't necessarily imply that the recipient has *read* the message, only that it was *sent* or *issued*. In technical terms, it refers to the 'dispatch' of the notification. If you want to confirm they understood, you need to use words like 'kakunin suru' (confirm) or 'ryoukai suru' (understand).

Japanese has many words for 'informing,' and choosing the right one depends on the level of formality and the relationship between the speaker and listener. 通知する (tsuuchi suru) sits in the middle-to-high range of formality.

通知 (Tsuuchi) vs. 連絡 (Renraku)
Renraku is the most versatile word. It means 'to contact' or 'to get in touch.' It implies a two-way flow. If you 'renraku' someone, you might expect a reply. 'Tsuuchi' is more like a broadcast; the sender provides info, and the receiver acknowledges it.
通知 (Tsuuchi) vs. 告知 (Kokuchi)
Kokuchi is used for public announcements, like a movie release date or a concert notice. It is often used for 'advertising' or 'publicizing' something to an undefined large group. 'Tsuuchi' is usually directed at specific individuals (e.g., specific customers, specific students).
通知 (Tsuuchi) vs. 報告 (Houkoku)
Houkoku is 'reporting' results to a superior. You 'houkoku' your sales numbers to your manager. You 'tsuuchi' the company's new policy to the staff.

イベントの開催を告知する。(Publicly announce the holding of an event.)
合格を本人に通知する。(Formally notify the person of their passing.)

For very casual situations, stick to 知らせる (shiraseru) or 教える (oshieru). 'Shiraseru' is the direct equivalent of 'to let someone know.' It is perfectly polite for daily use but lacks the 'official' stamp of 'tsuuchi.' For example, 'Let me know when you arrive' is 'tsuitara shirasete,' never 'tsuuchi shite.'

ریشه کلمه

Composed of Sinitic roots (Kango). 'Tsuu' (通) means to pass through or communicate. 'Chi' (知) means to know or knowledge. It entered the Japanese lexicon through formal administrative language.

معنای اصلی: To pass knowledge to another person.

بافت فرهنگی

Be careful when 'notifying' someone of bad news (like firing or failure). Use very polite Keigo to soften the blow.

In English, we use 'notification' for everything from a Facebook like to a legal summons. In Japanese, 'tsuuchi' is slightly more formal than a mere 'app alert' in nuance, though it is used for both.
