설명 口頭発表 in your Level:

At the A1 level, the word '口頭発表' (kōtō happyō) might seem a bit long and difficult, as it contains four kanji characters. However, it is an essential word for students. At this stage, you should understand that it means 'speaking in front of the class.' You might hear your teacher say, 'Ashita, happyō shimasu' (Tomorrow, you will present). Adding 'kōtō' (oral) just makes it more specific. Think of it as 'talking homework.' You don't need to use this word in complex sentences yet. Just recognize that when you see '口' (mouth) and '発表' (announcing), it means you have to speak. A1 learners can use it with simple verbs like 'shimasu' (do) or 'arimasu' (there is). For example, 'Kōtō happyō ga arimasu' means 'I have an oral presentation.' This is a great way to start using more formal vocabulary early on.

For A2 learners, '口頭発表' becomes a word used to describe school life and basic activities. You are beginning to understand that 'kōtō' (口頭) specifically means 'by mouth' or 'verbal.' You might use this word to explain your schedule to others. For example, 'Kōtō happyō no tame ni, eigo o renshū shimasu' (I practice English for my oral presentation). At this level, you can start to use particles like 'no' to connect it to other nouns, such as 'kōtō happyō no shiryō' (presentation materials). You should also be able to distinguish between a 'speech' and a 'kōtō happyō.' While a speech is often just words, a 'kōtō happyō' usually involves some kind of preparation or slides. If you are studying in Japan, you will hear this word often in your Japanese language school when projects are assigned.

At the B1 level, you are expected to use '口頭発表' in more professional or academic contexts. This is the level where you start to care about the quality of the presentation. You might use verbs like 'junbi suru' (prepare), 'seikō saseru' (make successful), or 'kinchō suru' (get nervous). B1 learners should understand the structure of a 'kōtō happyō,' including the introduction and the Q&A session (質疑応答 - shitsugi ōtō). You can use this word to talk about your research or a project you are working on. For instance, 'Kōtō happyō no saichū ni, shitsumon o uketsukemasu' (I will take questions during the oral presentation). You are also starting to see how this word fits into the larger vocabulary of 'happyō' (presentation/announcement), distinguishing it from written reports or poster sessions. This level is about using the word accurately in formal environments.

B2 learners should have a firm grasp of '口頭発表' and be able to use it in complex sentences with sophisticated grammar. You will encounter this word in academic papers, conference programs, and formal business reports. At this level, you should be able to discuss the 'composition' (kōsei) and 'delivery' (dentatsu) of the presentation. You might use phrases like 'kōtō happyō o o行う' (to conduct an oral presentation) instead of the simpler 'suru.' You should also understand the nuances of register—knowing when to use 'purezen' (casual/business) versus 'kōtō happyō' (formal/academic). B2 learners can also describe the feedback received, such as 'Kōtō happyō no naiyō ga takaku hyōka sareta' (The content of the oral presentation was highly evaluated). This level requires a deep understanding of the word's role in Japanese institutional culture.

For C1 learners, '口頭発表' is a tool for professional and academic excellence. You should be able to analyze the rhetorical strategies used in a 'kōtō happyō.' You might discuss the 'effectiveness' (yukōsei) of the presentation or the 'logical consistency' (ronriteki seigōsei) of the spoken content. At this level, you are not just giving a presentation; you are mastering the art of the 'kōtō happyō.' You will encounter the term in contexts like 'kōtō happyō no gijutsu' (the technique of oral presentation) or when discussing the historical development of academic communication in Japan. You should be able to use the word in the passive voice, causative-passive, and other advanced structures fluently. For example, 'Kōtō happyō o saserareru' (to be made to give an oral presentation). You understand that this word carries the weight of academic tradition and professional standards.

At the C2 level, you have a native-like understanding of '口頭発表.' You can use it to discuss the nuances of communication theory or the sociological aspects of academic discourse. You might use the word in highly specialized contexts, such as 'kōtō happyō ni okeru hi-gengo dentatsu' (non-verbal communication in oral presentations). You are comfortable using the word in any register, from high-level academic debates to formal policy discussions. You understand the historical roots of the term and how it contrasts with older forms of public speaking in Japan, such as 'enzetsu' (oratory). For a C2 learner, '口頭発表' is just one part of a vast repertoire of communication terms, and you can switch between them with precision and elegance. You could even lead a workshop on how to improve 'kōtō happyō' skills for native Japanese speakers, focusing on clarity, impact, and cultural appropriateness.

口頭発表 30초 만에

口頭発表 (kōtō happyō) means 'oral presentation,' a formal way to share information verbally in academic or business contexts.
It combines 'oral' (口頭) and 'presentation' (発表), distinguishing it from written reports or poster sessions.
Commonly paired with verbs like 'を行う' (to conduct) or 'の準備をする' (to prepare for).
Essential for university students and researchers in Japan for thesis defenses and academic conferences.

The Japanese term 口頭発表 (こうとうはっぴょう - kōtō happyō) is a formal compound noun that translates directly to 'oral presentation.' It is a fundamental term in academic, professional, and educational settings across Japan. To understand its essence, one must look at its constituent parts: kōtō (口頭), meaning 'oral' or 'by word of mouth,' and happyō (発表), meaning 'announcement,' 'publication,' or 'presentation.' Together, they describe the act of delivering information, research findings, or proposals verbally to an audience, typically supported by visual aids like slides or posters.

Academic Context: In universities, students engage in kōtō happyō during seminars (zemi) or to defend their graduation thesis. It implies a level of formality and structured delivery that distinguishes it from a casual talk.
Professional Context: At academic conferences (gakkai) or business symposiums, this term is the standard label for scheduled sessions where speakers present their work to peers.

来週のゼミで、私の研究に関する口頭発表を行います。
(I will give an oral presentation regarding my research in next week's seminar.)

When people use this word, they are highlighting the medium of communication. In contrast to a poster presentation (ポスター発表) or a written report (レポート), the emphasis here is on the speaker's ability to articulate thoughts clearly and handle a Q&A session (質疑応答). The word carries a weight of responsibility; it suggests that the speaker has prepared a logical flow of information intended to persuade or inform an audience.

学会での口頭発表は、一人十五分と決められています。
(Oral presentations at the conference are limited to fifteen minutes per person.)

Culturally, the kōtō happyō is a rite of passage for many Japanese students. It represents the transition from passive learning to active contribution. The structure usually follows a strict 'Introduction, Methods, Results, Discussion' (IMRAD) format in scientific fields, or a 'Ki-Sho-Ten-Ketsu' (Introduction, Development, Twist, Conclusion) structure in more humanities-based or traditional presentations. Understanding this word is key to navigating any formal environment where ideas are exchanged.

Register: Formal (Keigo-adjacent). You would rarely use this when talking about telling a story to a friend. It implies a podium, slides, and an audience.

彼は口頭発表の準備のために、毎日遅くまで大学に残っています。
(He stays late at the university every day to prepare for his oral presentation.)

Furthermore, the word 'kōtō' (口頭) is often contrasted with 'hikki' (筆記 - written). In exams, for instance, you might have a 'hikki shiken' (written exam) and a 'kōtō shiken' (oral exam). This distinction is vital for learners to grasp, as it helps categorize various forms of evaluation and communication.

緊張して、口頭発表の内容を一部忘れてしまった。
(I got nervous and forgot part of the content of my oral presentation.)

Etymology Note: The kanji 口 (mouth) represents the verbal nature, while 頭 (head) in this context refers to the 'front' or 'immediate' aspect of speech. Together with 発表 (announcing/expressing), it creates a comprehensive image of speaking one's thoughts forward.

審査員は、彼の口頭発表を高く評価した。
(The judges highly evaluated his oral presentation.)

Using 口頭発表 (kōtō happyō) correctly involves pairing it with the right verbs and particles to indicate the stage of the presentation process. Because it is a noun, it often functions as the object of a sentence or the subject of a passive construction. The most common verb used with it is okonau (行う - to perform/conduct) or suru (する - to do).

Common Verb Pairings: 口頭発表を行う (To give a presentation), 口頭発表の準備をする (To prepare for a presentation), 口頭発表を聞く (To listen to a presentation).

明日の会議で、新プロジェクトに関する口頭発表を行う予定です。
(I plan to give an oral presentation regarding the new project at tomorrow's meeting.)

When discussing the quality or state of a presentation, you might use adjectives or modifying phrases. For example, a 'successful' presentation is seikō shita kōtō happyō. To describe the act of preparing, you use the particle no tameno (のための - for the purpose of).

Modifiers: 素晴らしい口頭発表 (A wonderful oral presentation), 形式的な口頭発表 (A formal oral presentation), 準備不足の口頭発表 (An ill-prepared oral presentation).

口頭発表の資料を作成するのに、三日もかかりました。
(It took me three days to create the materials for the oral presentation.)

In academic writing, you might see this word in the passive voice or as part of a list of requirements. For example, 'Presentations will be conducted in English' would be Kōtō happyō wa eigo de okonawaremasu. This usage is very common in conference guidelines and syllabi.

この研究の結果は、昨年の国際会議での口頭発表に基づいています。
(The results of this research are based on an oral presentation at last year's international conference.)

In a classroom setting, a teacher might say, 'Next, we will begin the oral presentations.' In Japanese, this would be Tsugi ni, kōtō happyō o hajimemasu. Notice how the word remains unchanged regardless of the complexity of the sentence; it is a stable, formal block of meaning.

Interaction with Time: 口頭発表の直前 (Just before the oral presentation), 口頭発表の後で (After the oral presentation), 口頭発表の最中に (During the oral presentation).

口頭発表の最中に、プロジェクターが故障してしまった。
(During the oral presentation, the projector broke down.)

Lastly, when giving feedback, you might say, 'Your oral presentation was very clear.' This would be Anata no kōtō happyō wa totemo meikaku deshita. Using this specific term rather than just 'presentation' shows a respect for the formal structure of the event.

彼は、初めての口頭発表とは思えないほど堂々としていた。
(He was so dignified it was hard to believe it was his first oral presentation.)

If you are living in Japan or interacting with Japanese institutions, 口頭発表 (kōtō happyō) is a word you will encounter in specific, high-stakes environments. It is not a word you usually hear at a bar or a casual family dinner, but it is ubiquitous in the following four areas.

1. Higher Education: From undergraduate seminars to PhD defenses, the 'kōtō happyō' is the primary way students prove their mastery of a subject. You will see it on syllabi, university bulletin boards, and in emails from professors.

卒業論文の審査には、口頭発表が含まれます。
(The graduation thesis examination includes an oral presentation.)

In these academic settings, the word is often used to distinguish the 'live' part of an assignment from the 'written' part. A student might say, 'I finished the paper, but I'm still nervous about the kōtō happyō.'

2. Academic Conferences (Gakkai): In Japan, 'Gakkai' culture is massive. Thousands of researchers meet annually to share findings. On the official programs, sessions are clearly divided into 'Poster Sessions' and 'Oral Presentations' (口頭発表). Hearing this word here signals a formal talk in a lecture hall.

今回の学会では、ポスター発表ではなく、口頭発表に選ばれた。
(At this conference, I was selected for an oral presentation rather than a poster presentation.)

When you attend these events, the chairperson will introduce speakers by saying, 'The next oral presentation is by [Name] from [University].' This formal introduction reinforces the status of the speaker.

3. Formal Business and Government: While 'purezen' is common in tech startups, traditional Japanese companies and government agencies use 'kōtō happyō' for official reports or when presenting to a committee. It sounds more authoritative and traditional.

市役所の会議で、新しい公園の計画について口頭発表を行った。
(I gave an oral presentation about the new park plan at the city hall meeting.)

In these contexts, the 'kōtō happyō' is often recorded in the official minutes (gijiroku). It is a matter of public or corporate record.

4. Language Proficiency Exams (JLPT/EJU): If you are taking the JLPT N2 or N1, or the Examination for Japanese University Admission (EJU), you will see this word in reading passages about education or in listening tasks describing school schedules. It is a 'vocabulary of the educated.'

試験の要項によると、二次試験では口頭発表の能力が問われる。
(According to the exam guidelines, the second exam tests oral presentation ability.)

彼女の口頭発表は、図表の使い方が非常に巧みだった。
(Her oral presentation was very skillful in its use of charts and diagrams.)

When using 口頭発表 (kōtō happyō), English speakers often fall into a few common traps. Because the word 'presentation' is so versatile in English, learners tend to over-apply or under-apply the Japanese equivalent.

Mistake 1: Using it for casual sharing: If you are just showing photos of your vacation to friends, do NOT call it a 'kōtō happyō.' This sounds incredibly stiff and robotic. Use 'misetai mono ga aru' (I have something to show) or 'hanashitai koto ga aru' (I have something to tell you).

❌ 友達に旅行の口頭発表をした。
✅ 友達に旅行の写真を見せた。
(I showed my travel photos to my friends.)

The term kōtō happyō requires a formal structure, usually involving a specific topic, research, or a proposal, and a clear audience-speaker distinction.

Mistake 2: Confusing it with 'Speech' (スピーチ): A 'speech' (supīchi) is often focused on the speaker's personal feelings, a wedding toast, or a political address. A 'kōtō happyō' is data-driven or information-heavy. If you are giving a toast at a wedding, calling it a 'kōtō happyō' would make people think you are about to present a PowerPoint on the couple's relationship statistics.

❌ 結婚式で口頭発表をした。
✅ 結婚式でスピーチをした。
(I gave a speech at the wedding.)

Another error is the incorrect use of the verb. While 'suru' is acceptable, in formal contexts, 'okonau' (行う) is much more natural. Using 'iu' (言う - to say) with kōtō happyō is a common beginner mistake.

Finally, watch out for the pronunciation of 'happyō.' Many learners forget the small 'tsu' (っ) sound, making it 'hapyō.' This changes the rhythm and can make the word hard to understand. It should be hap-pyō with a distinct pause.

❌ 口頭はぴょう (Hapyō)
✅ 口頭発表 (Happyō)
(Ensure the double 'p' sound is clear.)

Mistake 3: Particle Errors: Learners often say 'kōtō happyō ni' when they mean 'at the presentation.' Usually, 'kōtō happyō de' (using the location/means particle 'de') is more appropriate when describing what happened during the event.

❌ 口頭発表に質問をした。
✅ 口頭発表で質問をした。
(I asked a question at the oral presentation.)

Japanese has several words for 'presentation' or 'speaking in public.' Choosing the right one depends entirely on the context and the level of formality required. Here is a comparison of 口頭発表 (kōtō happyō) against its closest relatives.

1. プレゼンテーション (Purezentēshon): Often shortened to プレゼン (purezen). This is the modern, loanword equivalent. It is used heavily in business, marketing, and tech. It feels more 'dynamic' and 'visual' than 'kōtō happyō.' While 'kōtō happyō' feels like a lecture, 'purezen' feels like a pitch.

クライアントに向けて、新商品のプレゼンを行う。
(Give a presentation/pitch to a client about a new product.)

2. 講演 (Kōen): This means 'lecture' or 'address.' It usually refers to a one-sided talk given by an expert or celebrity to a large audience. Unlike 'kōtō happyō,' which implies sharing specific research/results, a 'kōen' is often about sharing wisdom, experiences, or a broad overview of a field.

有名な作家の講演を聞きに行った。
(I went to hear a lecture by a famous author.)

3. スピーチ (Supīchi): As mentioned before, this is 'speech.' It is personal, emotional, or ceremonial. It rarely involves slides or technical data. Think of an Oscar acceptance speech or a graduation speech.

卒業生代表としてスピーチをした。
(I gave a speech as the representative of the graduates.)

4. 報告 (Hōkoku): This means 'report.' It is the most common word for sharing progress in a business setting. It doesn't necessarily have to be 'oral.' A 'hōkoku' is about facts and status updates rather than the formal 'performance' aspect of a 'kōtō happyō.'

Understanding these nuances will make your Japanese sound much more natural. If you are a student, stick with kōtō happyō when talking to professors. If you are in a startup, purezen is your best friend.

研究成果の発表は、二つの形式があります。一つは口頭発表、もう一つはポスター発表です。
(There are two formats for presenting research results. One is oral presentation, and the other is poster presentation.)

frequency

High in educational and professional spheres; low in daily casual conversation.

자주 하는 실수

Using 'kōtō happyō' for a casual chat. → Hanashi o suru / Misete ageru.
Kōtō happyō is reserved for formal, structured events.
Saying 'kōtō happyō o iu'. → Kōtō happyō o suru / okonau.
You 'do' or 'conduct' a presentation, you don't 'say' it.
Forgetting the 'u' in 'kōtō'. → Kōtō (こうとう).
Without the 'u', it sounds like 'koto' (thing), which is confusing.
Using it for a written report. → Repōto / Happyō.
Kōtō specifically means 'oral'. If you just wrote it, it's not 'kōtō'.
Thinking 'purezen' is the only word. → Kōtō happyō (in academic settings).
Using 'purezen' in a formal thesis defense might sound too casual to some professors.

팁

Use 'Okonau' for Formality

While 'kōtō happyō o suru' is okay, 'kōtō happyō o okonau' sounds much more professional and is preferred in writing.

The Bow

Always start and end with a bow. It shows respect to the audience and the formal nature of the 'kōtō happyō'.

Contrast with Poster

Remember that 'kōtō happyō' is often paired with 'poster happyō'. Knowing both helps you navigate conference programs.

Clear Enunciation

In a 'kōtō happyō', speaking clearly (hakkiri hanasu) is more important than speaking fast. Take your time.

Visual Aids

Don't just talk; 'kōtō happyō' almost always implies you have some 'shiryō' (materials) for the audience to look at.

Q&A Grace

When asked a question during 'shitsugi ōtō', start by saying 'Go-shitsumon arigatō gozaimasu' (Thank you for your question).

Abstracts

Learn the word 'yōshi' (要旨). You will almost always have to write one before you can do your 'kōtō happyō'.

Pitch Check

Keep the pitch relatively flat and steady. Over-emphasizing syllables can make you sound like you're reading a storybook.

JLPT Context

This word often appears in N2/N1 listening sections where students discuss their seminar schedules.

Job Hunting

In Japanese job interviews (shūshoku katsudō), you might be asked to do a 'mini kōtō happyō' about your research.

암기하기

기억법

Think of a 'Mouth' (口) at the 'Top' (頭) of a person who is 'Happy' (ハッピー) because they are 'Presenting' (発表).

시각적 연상

Imagine a person standing behind a podium with a giant cartoon 'mouth' icon on the screen behind them.

Word Web

口 (Mouth) 頭 (Head) 発 (Emit) 表 (Surface) プレゼン (Presentation) 大学 (University) 学会 (Conference) 緊張 (Nervous)

챌린지

Try to say 'Kōtō happyō' five times fast without missing the small 'tsu' in 'happyō'.

어원

The word is a Sino-Japanese (Kango) compound. 'Kōtō' (口頭) comes from 'Mouth' (口) and 'Head/Front' (頭). 'Happyō' (発表) comes from 'Emit/Start' (発) and 'Surface/Express' (表).

원래 의미: The combination literally means 'to express something forward via the mouth.'

Japonic / Sinitic loanwords (Kango).

문화적 맥락

Be careful not to confuse 'kōtō' with 'kōtō' (high school). They sound the same but have different kanji and pitch.

In English-speaking countries, 'oral presentation' can sound very formal; students often just say 'giving a talk' or 'doing a presentation.'

Graduation thesis (Sotsuron) presentations in anime like 'Honey and Clover'. Academic conference scenes in medical dramas like 'Doctor X'. Business pitch scenes in 'Hanzawa Naoki'.
