Erklärung 通報 in your Level:

At the A1 level, you should learn 通報 (tsūhō) as a word related to safety and emergencies. Think of it as the word you use when you need to call '110' for the police or '119' for a fire. You don't need to know complex legal details yet. Just remember the phrase 'Keisatsu ni tsūhō suru' (Report to the police). It is an important 'survival' word. In Japan, you might see this word on posters near schools or in train stations. If you see a crime or a fire, you 'tsūhō' to the authorities. It is a 'suru-verb,' so you can say tsūhō shimasu (I will report) or tsūhō shimashita (I reported). Even at this basic level, knowing this word helps you understand that some reporting is only for the police or fire department, not for friends or teachers.

At the A2 level, you can start using 通報 (tsūhō) in more complete sentences. You should understand that it is used for specific emergency situations. For example, 'Kaji o tsūhō suru' (to report a fire). You also learn the particle ni to show who you are reporting to: 'Shōbōsho ni tsūhō suru' (to report to the fire station). At this level, you might also see the word used on the internet. If you see a bad comment on a website, you might see a button that says 'Report' in English, but in Japanese, it might say tsūhō. You can also distinguish it from renraku (contact). Renraku is for calling a friend; tsūhō is for calling the police. This distinction is key for natural Japanese communication.

At the B1 level, you should be able to use 通報 (tsūhō) to describe events you see in the news. You will notice that news reporters often say 'Jūnin kara no tsūhō' (a report from a resident). You should also understand the passive form 'tsūhō sareru' (to be reported). For instance, 'Kare wa fushin-sha to shite tsūhō sareta' (He was reported as a suspicious person). This level involves understanding the social responsibility associated with the word. You might also encounter the word in workplace safety contexts, such as what to do if you find a gas leak or a security breach. You should be comfortable using the word in both spoken and written Japanese when discussing public safety or rules violations.

At the B2 level, you will encounter 通報 (tsūhō) in more formal and legalistic contexts. This includes terms like 'Naibu-tsūhō' (internal whistleblowing) and 'Tsūhō-sha hogo' (protection of informants/whistleblowers). You should understand the nuance of 'mandatory reporting' (tsūhō gimu). For example, in Japan, if a person suspects child abuse, they have a legal duty to report it. You can discuss the ethics of reporting and the difference between tsūhō (official report) and mikkoku (snitching). Your vocabulary should expand to include synonyms like kokuhatsu (denunciation) and how they differ in legal weight. You should be able to read newspaper articles about police investigations and understand the role of the tsūhō in starting the investigation.

At the C1 level, your understanding of 通報 (tsūhō) should include its administrative and systemic implications. You can analyze how the reporting system functions in Japanese society, such as the effectiveness of the '110-ban' system or the societal pressure that leads to certain types of tsūhō. You will encounter the word in legal documents, government white papers, and academic texts on sociology or law. You should be able to use the word in nuanced debates about privacy versus public safety. For example, discussing whether the increase in social media tsūhō (reporting) is leading to more censorship. You should also be familiar with the historical evolution of the word and its kanji components, understanding how 'communication' (通) and 'report' (報) combine to create this formal concept.

At the C2 level, you have a masterly grasp of 通報 (tsūhō) across all registers. You can use it in high-level legal discourse, policy-making contexts, or literary analysis. You understand the subtle emotional undertones when the word is used in literature to describe a character's betrayal or their commitment to justice. You can differentiate between the various types of reporting systems (e.g., shōbō-tsūhō vs. kaijō-hoan-tsūhō for maritime safety). You are also aware of the international equivalents and can translate the specific Japanese cultural nuance of 'community monitoring' that tsūhō often implies. You can write professional reports or academic papers that utilize the term with absolute precision, acknowledging its legal definitions and societal consequences.

通報 in 30 Sekunden

Formal report to authorities (police/fire).
Used for crimes, accidents, and emergencies.
Often combined with 'suru' to mean 'to report.'
Key for public safety and emergency situations.

The Japanese word 通報 (つうほう - tsūhō) is a formal noun that translates most accurately to 'report,' 'notification,' or 'alert' in the context of contacting official authorities. Unlike the general word for reporting information in a business setting (報告 - hōkoku) or simply contacting someone (連絡 - renraku), tsūhō is specifically reserved for situations involving the police, fire department, or other regulatory bodies. When you witness a car accident, a theft, or a suspicious person, the act of dialing 110 (the Japanese emergency number for police) and providing details is termed 通報. It implies a sense of urgency and a request for official intervention. In the modern digital age, this word has also expanded to include reporting inappropriate content or harassment on social media platforms, though the core meaning of 'alerting an authority to a problem' remains consistent.

Official Reporting: The most common usage is in emergency services. For example, keisatsu ni tsūhō suru means to report something to the police.

近所で火事を見つけたので、すぐに消防署に通報しました。(I saw a fire in the neighborhood, so I immediately reported it to the fire department.)

Furthermore, 通報 is used in legal and administrative contexts. For instance, 'mandatory reporting' (義務的通報) refers to the legal obligation of certain professionals, like doctors or teachers, to alert authorities if they suspect child abuse or elder neglect. The word carries a weight of responsibility; it is not merely sharing news, but initiating a formal process that may lead to investigation or emergency response. In news broadcasts, you will frequently hear the phrase kinrin no jūnin kara no tsūhō (a report from a nearby resident), which sets the stage for how a crime or incident was first discovered by the authorities.

Social Media Context: On apps like X (Twitter) or YouTube, the 'Report' button is often labeled as tsūhō or hōkoku, used to flag violations of terms of service.

不適切な投稿を見つけたら、運営に通報してください。(If you find an inappropriate post, please report it to the management.)

Understanding the nuance of 通報 is vital for navigating life in Japan safely. It is a word associated with civic duty and public safety. While it might sound intimidating, knowing how to use it correctly ensures that you can communicate effectively in high-pressure situations where every second counts. It is a 'high-register' word, meaning it sounds professional and serious, fitting its role in law enforcement and emergency response contexts.

Using 通報 (tsūhō) correctly involves understanding its function as both a noun and a suru-verb. As a noun, it often appears in phrases like tsūhō o ukeru (to receive a report) or tsūhō ga hairu (a report comes in). As a verb, tsūhō suru (to report), it typically takes the target authority as the indirect object marked by the particle に (ni). For example, 'Report to the police' is keisatsu ni tsūhō suru. The reason for the report is often marked by the particle を (o) or phrased as a separate clause ending in to (that).

Verb Usage: The verb form tsūhō suru describes the action of making the call or filing the alert. It is active and direct.

通行人が、道端で倒れている人を見つけて警察に通報した。(A passerby found a person collapsed on the roadside and reported it to the police.)

In passive contexts, tsūhō sareru (to be reported) is often used when someone is the subject of a report, usually due to suspicious or illegal behavior. For example, 'He was reported by a neighbor' would be kare wa kinrin no jūnin ni tsūhō sareta. This highlights the social monitoring aspect of the word. In formal reports or news, you might see the noun form coupled with ni yoru (due to/by way of), as in shimin no tsūhō ni yori (thanks to a report from a citizen).

Passive/Receiving: Police officers often describe their arrival at a scene by saying they received a report: tsūhō o ukete genba ni kyūkō shita (rushed to the scene after receiving a report).

「怪しい男がいる」という通報を受け、警察官が駆けつけた。(Police officers arrived after receiving a report saying 'there is a suspicious man.')

Finally, the word appears in compound nouns like tsūhō sōchi (reporting device/alarm) or tsūhō gimu (duty to report). These terms are common in legal documents and safety manuals. For students of Japanese, mastering the collocation keisatsu ni tsūhō suru is the most practical starting point, as it appears in almost every crime-related news story or detective drama.

You will encounter 通報 (tsūhō) in several specific environments in Japan. The most frequent is the daily news cycle. Whether on television, radio, or news websites, reports of accidents, fires, and crimes invariably mention how the authorities were alerted. You will hear anchors say, 'Tōri-kakatta hito ga tsūhō shimashita' (A person who happened to be passing by made the report). This phrasing is standard and helps establish the timeline of the event.

TV News & Media: In crime dramas (keisatsu-mono), characters often shout into their radios, 'Tsūhō ari!' (Report received!) or 'Tsūhō shiro!' (Make the report!).

ニュース：「午前3時ごろ、住民から『叫び声が聞こえる』と警察に通報がありました。」(News: Around 3 AM, there was a report to the police from a resident saying 'I can hear screaming.')

Another place you'll see this word is on social media and internet forums. Because of 'cyber-patrols' and community moderation, users are encouraged to tsūhō (report) accounts that engage in hate speech, spam, or scams. In Japanese internet slang, sometimes people use the word tsūhō humorously when someone posts something slightly 'illegal' or 'too lewd,' implying 'I'm calling the police on you' as a joke, though the word itself remains formal.

Daily Life & Safety: In apartment buildings, there are often notices about noise complaints or suspicious visitors, urging tenants to tsūhō the management or police.

掲示板：万引きを見つけたら、直ちに店員へ通報してください。(Bulletin Board: If you spot shoplifting, please report it to a staff member immediately.)

Finally, in professional settings like hospitals, schools, or social work offices, 通報 is a technical term used in meetings to discuss legal obligations. If a teacher sees signs of abuse on a child, they must discuss the 'tsūhō' process to the Child Guidance Center (Jidō Sōdan-jo). In these contexts, the word represents a serious, bureaucratic step taken to protect individuals, emphasizing that it is an official action rather than a personal choice.

One of the most frequent mistakes learners make is confusing 通報 (tsūhō) with 報告 (hōkoku). While both involve 'reporting' information, their contexts are mutually exclusive. Hōkoku is used for reporting progress to a boss, giving a summary of a trip to your parents, or providing a status update on a project. Using tsūhō in a business meeting to say 'I reported the sales figures to the manager' would sound very strange, as it implies you called the police to tell them about your sales numbers!

Tsūhō vs. Hōkoku: Tsūhō: Police, Fire, Authorities, Emergencies.
Hōkoku: Boss, Work, General Information Sharing.

❌ 上司に売上を通報しました。 (Incorrect: Reported sales to the boss like a crime.)
✅ 上司に売上を報告しました。 (Correct: Reported sales to the boss.)

Another mistake involves the particles. Many learners use o (direct object) for the person they are reporting to, but ni (indirect object) is much more natural for the authority receiving the report. For example, keisatsu o tsūhō suru is grammatically possible but often interpreted as 'reporting the police (for doing something wrong),' whereas keisatsu ni tsūhō suru means 'reporting (an incident) TO the police.'

Particle Confusion: Use に for the police/fire station. Use を for the crime or the person being reported.

✅ 泥棒を警察に通報する。(Report the thief to the police.)

Lastly, don't use tsūhō for reporting a simple sickness or absence from school. If you are sick and calling your teacher, use renraku (contact) or todoke (notice). If you use tsūhō, the teacher might think you are reporting a crime or a major public health emergency. Keep tsūhō in your 'emergency/official' vocabulary bucket to avoid causing unnecessary alarm or sounding overly dramatic.

Japanese has many words for 'reporting' or 'notifying,' and choosing the right one depends on the target and the severity of the information. 報告 (hōkoku) is the general-purpose word for reporting facts or results in a hierarchy, like a subordinate to a superior. 連絡 (renraku) is for general communication or staying in touch. 通知 (tsūchi) is used for formal notifications, often from an institution to an individual, like a 'Notice of Acceptance' or a 'Payment Notice.'

Tsūhō vs. Todokede: Tsūhō: Often urgent, reporting an incident or crime (e.g., calling 110).
Todokede (届け出): Official filing of paperwork (e.g., registering a birth or marriage).

役所に住所変更を届け出る。(File a notice of address change at the ward office.)

When the reporting involves accusing someone of a crime specifically to seek punishment, the word 告訴 (kokuso) or 告発 (kokuhatsu) is used. Kokuso is a complaint filed by a victim, while kokuhatsu is a report filed by a third party. These are much more legalistic and heavy than a simple tsūhō. Another related word is 密告 (mikkoku), which means 'secretly informing' or 'snitching,' often with a negative connotation of betrayal.

Comparison Table

通報 (Tsūhō): Emergency/Incident alert.
告発 (Kokuhatsu): Formal legal denunciation.
密告 (Mikkoku): Snitching/Secret reporting.
申告 (Shinkoku): Declaration (e.g., tax return).

彼は税務署に申告を忘れた。(He forgot to file his declaration at the tax office.)

In summary, 通報 sits in a unique spot: it is more serious than a casual contact, more urgent than a standard report, and more 'public-safety' oriented than a formal legal accusation. By understanding these alternatives, you can precisely describe the act of sharing information based on the gravity of the situation and the person receiving the news.

Tipps

Authority Only

Always remember that 'tsūhō' is for authorities. Don't use it for your friends or family unless you are being dramatic or joking.

Particle Choice

Use 'ni' for the agency (Police ni) and 'o' for the event (Fire o). This is the most natural way to structure the sentence.

110 and 119

In Japan, 110 is for police and 119 is for fire/ambulance. Both acts are described as 'tsūhō'.

Reporting Posts

If you see the word '通報' on a Japanese website, it's the button you press to report a user or a post.

Whistleblowing

The word for whistleblowing is 'naibu-tsūhō'. It's a key term in Japanese corporate governance.

Calling 110

When you call 110, the operator will ask 'Jiken desu ka, jiko desu ka?' (Is it a crime or an accident?). Your answer is part of the 'tsūhō'.

Long Vowels

The first kanji 'tsū' means to pass through. The second 'hō' means to report. It's 'passing information through to the top'.

Don't confuse with Hōkoku

Hōkoku = Boss/Work. Tsūhō = Police/Emergency. This is the most important distinction for learners.
