解析告知 in your Level:

At the A1 level, you can think of '告知' (kokuchi) as a very formal way to say 'news' or 'announcement.' You might see it on a poster for a Japanese festival or a concert. Even if you don't use it yourself yet, recognizing it on signs is helpful. It basically means 'Official Notice.' Imagine a big sign that says 'IMPORTANT ANNOUNCEMENT'—that is what '告知' feels like in Japanese. You will mostly see it as a noun at this stage.

At the A2 level, you should understand that '告知' is used in formal situations. You might encounter it in simple business emails or on official websites. You can start using it as a verb: '告知する' (to announce). For example, if you are organizing a small study group, you might 'kokuchi' the time and place. It's more formal than 'oshirase' (notice). You should also be able to recognize it in the context of 'event announcements' on social media.

告知 30秒了解

告知 (kokuchi) is a formal Japanese word for an official announcement or notice, used by authorities or organizations.
It is commonly found in business press releases, event notices, and serious medical diagnoses like cancer.
Grammatically, it functions as a noun or a suru-verb, often appearing in patterns like 'event no kokuchi'.
Compared to 'oshirase', it is much more formal and carries a sense of official weight and finality.

The Japanese word 告知 (kokuchi) is a formal noun that translates most accurately as 'announcement,' 'notification,' or 'notice.' While English has several words for sharing information, kokuchi occupies a specific linguistic space defined by formality, officialdom, and often a one-way flow of critical information. It is not the kind of word you use when telling a friend you bought a new pair of shoes; rather, it is the word a corporation uses to announce a merger, a government uses to notify the public of a new law, or a doctor uses to deliver a significant medical diagnosis.

Etymological Breakdown: The first kanji, 告 (koku), means to tell, inform, or announce. It depicts a mouth and a sign, representing the act of making a proclamation. The second kanji, 知 (chi), means to know or wisdom. Together, they literally mean 'to make known' in a structured, authoritative manner.

政府は新しい税制の導入を公式に告知した。
(The government officially announced the introduction of the new tax system.)

In business contexts, kokuchi is frequently seen on posters, websites, and in press releases. It carries a weight of finality and importance. For instance, an 'event notice' on a website would be labeled as イベントの告知. It implies that the details provided are the official version that the public needs to be aware of. Unlike shirase (お知らせ), which is a softer, more general term for 'news' or 'notice,' kokuchi feels more legalistic and rigorous.

Public Service Usage: When a city council decides to change trash collection dates, they issue a 告知. It is a formal declaration of fact intended to reach a specific audience who must act upon that information or acknowledge its truth.

The word is also a suru-verb (告知する), meaning 'to notify' or 'to announce.' When used as a verb, it emphasizes the action of the authority figure or entity disseminating the information. Because of its formal nature, you will rarely hear it in casual conversation unless the topic is inherently serious or professional. Using it in a casual setting might make you sound overly stiff or like you are mimicking a news anchor.

裁判所からの告知を無視してはいけない。
(You must not ignore the notification from the court.)

Marketing Nuance: In the world of advertising, 告知物 (kokuchibutsu) refers to promotional materials like flyers or posters that 'announce' a sale or a new product launch. It is a technical term used within marketing departments.

Using 告知 (kokuchi) correctly requires an understanding of its grammatical versatility. It functions primarily as a noun but frequently transforms into a verb by adding suru. In its noun form, it often appears in the pattern [Topic] + の + 告知 (Announcement of [Topic]). In its verb form, it follows the pattern [Information] + を + 告知する (To announce [Information]).

Pattern 1: The Noun Usage: When using it as a noun, it often acts as the subject or object of a sentence. For example, 'The announcement was late' becomes 告知が遅れた (Kokuchi ga okureta). This is the most common way to refer to the 'notice' itself as a physical or digital entity.

ウェブサイトでイベントの告知を確認してください。
(Please check the event announcement on the website.)

When you want to describe the act of notifying someone, the verb form kokuchi suru is used. This is common in professional settings where a specific person or group is being informed of a decision. It is more formal than shiraseru (to inform) and suggests a level of authority or official capacity held by the person doing the announcing.

Pattern 2: The Verb Usage: The verb form 告知する is transitive, meaning it takes a direct object (the thing being announced). Example: 結果を告知する (Kekka o kokuchi suru - To announce the results).

医師は患者に病名を告知した。
(The doctor notified the patient of the name of their illness.)

A key distinction in usage is the recipient. If you are notifying a specific person of something important, kokuchi is appropriate. If you are announcing something to the general public for entertainment purposes, happyou or senden might be more common, though kokuchi is still used for the 'official notice' part of that promotion.

Passive Usage: In formal reports, you might see the passive form: 告知された (kokuchi sareta - was announced/notified). This is used when the focus is on the person who received the news rather than the one who gave it.

Finally, consider the time aspect. Kokuchi is often used for things that *will* happen. It is the preliminary notice that sets the stage for a future event. Therefore, you will often see it paired with dates and times.

次回の会議の日程を告知します。
(I will announce the schedule for the next meeting.)

In daily life in Japan, you will encounter 告知 (kokuchi) in several specific environments. Understanding these contexts helps you grasp the word's 'weight' and social standing. It is a staple of professional communication and public administration.

1. The Medical Field: This is perhaps the most somber context. In Japan, the term 告知 is synonymous with the formal disclosure of a serious diagnosis. Historically, doctors in Japan sometimes withheld a cancer diagnosis from the patient, telling only the family. This practice has changed, and the 'act of informing the patient' is strictly called 告知.

本人への病名告知について家族と相談した。
(I consulted with the family regarding the notification of the disease name to the patient themselves.)

2. **Corporate and Tech Announcements**: When you follow Japanese companies on social media (like X/Twitter) or visit their official blogs, you will see 'Kokuchi' used for official updates. If a game developer is going to release a new patch or a singer is going to hold a concert, the post will often start with or be tagged as 【告知】. This signals to the reader: 'This is an official piece of news you should pay attention to.'

3. Legal and Administrative Notices: If you live in an apartment in Japan, you might see a 告知 from the management company about water pipe maintenance or fire alarm testing. These are official notices that require your attention and cooperation.

4. **Event Marketing**: In the entertainment industry, 'kokuchi' is the standard term for the 'reveal' of a project. A voice actor might say, 'I have an important kokuchi today!' to build hype. This usage is slightly more modern and leans into the 'exciting news' side of the word, though it maintains the sense that the information is 'official.'

新番組の告知動画が公開された。
(The announcement video for the new program has been released.)

5. Insurance and Contracts: In the insurance industry, there is a term called 告知義務 (kokuchi gimu), or the 'duty to disclose.' This refers to the legal requirement for the person taking out insurance to tell the company about their health history truthfully.

While 告知 (kokuchi) is a powerful word, English speakers often misuse it by confusing it with other Japanese words for 'announcement' or 'information.' The primary pitfall is using kokuchi in contexts that are too casual or where the information flow is informal.

Mistake 1: Confusing with 'Oshirase' (お知らせ): Many learners use 告知 when they should use お知らせ. Oshirase is polite and friendly, used for things like 'We are closing early today' or 'Here is a photo of my cat.' Using 告知 for a cat photo would sound like you are issuing a formal government decree about your pet.

❌ 友達にランチの場所を告知した。
✅ 友達にランチの場所を教えた/知らせた。
(I told my friend the lunch location.)

Mistake 2: **Confusing with 'Happyou' (発表)**. *Happyou* is used for presentations, public releases of creative works, or announcing results (like exam results). While there is overlap, *kokuchi* is more about the 'notice' or 'notification' of a fact, whereas *happyou* is the 'unveiling' or 'presentation' of something new.

Mistake 3: Overusing in Casual Speech: In spoken Japanese, you rarely say 'I will announce...' using 告知します unless you are in a meeting or on a stage. For daily life, use 言います (iimasu) or 伝えます (tsutaemasu). 告知 is a 'written-style' or 'public-style' word.

Mistake 4: Incorrect Kanji: Be careful not to confuse 告知 with 公表 (kouhyou). Kouhyou means to make something public that was previously private (like data or a scandal). 告知 is simply the act of notifying.

Finally, remember the specific medical nuance. If you use kokuchi in a hospital setting, people will immediately assume you are talking about a terminal or life-altering diagnosis. Use setsumei (explanation) for routine medical updates.

To truly master 告知 (kokuchi), you must see where it sits among its synonyms. Japanese has a rich vocabulary for 'telling,' each with a different level of formality and direction.

1. お知らせ (Oshirase): The most common alternative. It is polite but not overly formal. Used by shops, schools, and in emails. 告知 is the 'official version' of an お知らせ.

2. 発表 (Happyou): Means 'presentation' or 'public announcement.' Use this for creative works, research findings, or election results. 告知 is the notice that the 発表 is going to happen.

Comparison: 告知 (The notice of an event) vs. 発表 (The unveiling of the event's content).

3. **通知 (Tsuuchi)**: This means 'notification' or 'report.' It is often used for individual notifications, like a grade report (tsuuchihyou) or a notification from an app. While kokuchi is often public, tsuuchi is often private or directed at a specific recipient.

4. 報告 (Houkoku): Means 'report.' This is used when you are telling a superior about the progress of a task. It is a 'bottom-up' communication, whereas 告知 is usually 'top-down.'

5. 告示 (Kokuji): This is an even more formal version of 告知, used almost exclusively by the national government for official gazettes or public notices of laws.

6. **宣伝 (Senden)**: This means 'advertisement' or 'publicity.' If your 'announcement' is actually an attempt to sell something, senden is the more accurate term, though companies will use kokuchi to make their marketing sound like 'news.'

小贴士

When in doubt, use 'Oshirase'

If you aren't sure if a situation is formal enough for 'kokuchi', 'oshirase' is almost always a safe, polite alternative.

Medical Sensitivity

Remember that 'kokuchi' in a hospital can be very heavy. Use 'setsumei' (explanation) for minor medical updates.

Bracket Usage

In digital media, '告知' is often put in square brackets like 【告知】 to grab attention at the start of a post.

Suru-Verb Transformation

Don't forget that 'kokuchi' is a noun that needs 'suru' to become an action. 'Kokuchi shita' (I announced).

Listen for 'Koushiki'

You will often hear 'Koushiki kokuchi' (Official announcement). This is the redundant but common way to say 'Official Official Notice'.

Kanji Meaning

Focus on the 'Tell' (告) and 'Know' (知) components to remember the meaning: 'Tell so they Know'.

Marketing Strategy

Influencers use 'kokuchi' to make their followers feel like they are part of an important event or community milestone.

Duty to Disclose

If you ever sign a Japanese insurance contract, look for 'kokuchi gimu'. It's vital to be honest there.

Short Vowels

Ensure the 'u' in 'koku' is short. If you elongate it too much, it sounds like 'kookuchi', which is incorrect.

Context Clues

If you see '告知' followed by a date and time, it's almost certainly an event or maintenance notice.

文化背景

Be extremely careful using this word in medical contexts; it carries a heavy implication of serious illness.

English speakers might use 'announcement' for everything from a pregnancy to a sale. Japanese is more specific; 'kokuchi' is for the official notice part.

Medical dramas like 'Shiroi Kyoto' often feature intense 'kokuchi' scenes. The phrase 'Juuyou Kokuchi' (Important Announcement) is a common trope in anime cliffhangers. Insurance commercials in Japan frequently mention 'kokuchi gimu' (duty to disclose).
