A2 interjection #1,500 가장 일반적인 9분 분량

はい、そうです

hai, sou desu 상위 1,500

At the A1 level, learners encounter 'はい、そうです' as one of the very first phrases in their Japanese language journey. It is typically introduced in the first few chapters of any standard textbook, such as Genki or Minna no Nihongo, alongside basic introductions and noun sentences (A wa B desu). For a beginner, the primary goal is rote memorization and immediate practical application. Learners are taught to use this phrase as a universal 'Yes, it is' to answer simple, direct questions about identity, nationality, occupation, and basic object identification. For example, when asked 'Are you an American?' or 'Is this a book?', the A1 learner confidently replies 'Hai, sou desu.' At this stage, the grammatical breakdown of the phrase is less important than its functional utility. The learner relies on it as a safe, polite, and universally understood mechanism for confirming facts. It provides a sense of accomplishment, allowing the beginner to participate in basic question-and-answer exchanges without needing to construct complex sentences. The focus is entirely on pronunciation, recognizing the 'desu ka' question prompt, and responding with the appropriate affirmative phrase.

As learners progress to the A2 level, their understanding of 'はい、そうです' deepens beyond mere rote memorization. They begin to analyze the phrase grammatically, recognizing 'sou' as a demonstrative adverb meaning 'in that way' and 'desu' as the polite copula. This analytical understanding allows them to see how the phrase fits into the broader ko-so-a-do system of Japanese demonstratives. More importantly, A2 learners begin to grasp the crucial grammatical restriction: 'sou desu' can only be used to replace noun phrases, not verb phrases. They learn to avoid the common beginner mistake of answering 'Do you eat apples?' with 'Hai, sou desu,' instead correctly repeating the verb 'Hai, tabemasu.' Furthermore, A2 learners start to notice the phrase being used in everyday listening materials, such as simple dialogues, announcements, and basic interactions in stores or restaurants. They begin to use it more naturally, not just as a textbook response, but as a genuine tool for communication in predictable, everyday situations. They also start to experiment with dropping the 'hai' in slightly less formal, though still polite, contexts.

At the B1 level, learners transition from using 'はい、そうです' as a simple factual confirmation to utilizing it as a tool for conversational management. They become highly aware of 'Aizuchi,' the Japanese art of backchanneling, and begin to use variations of the phrase to show active listening and empathy. The B1 learner frequently employs 'そうですね' (sou desu ne) to express shared agreement or to soften their responses, recognizing that a blunt 'sou desu' can sometimes sound too direct or factual in a casual conversation about opinions. They also begin to understand the nuances of intonation; a drawn-out 'sooo desu ne' indicates deep thought or hesitation, while a crisp 'sou desu' indicates absolute certainty. At this stage, learners are comfortable navigating mixed registers, knowing when to use the polite 'sou desu' with acquaintances and when to switch to the casual 'un, sou' with close friends. The phrase becomes a dynamic part of their vocabulary, adaptable to the emotional and social context of the conversation, rather than a static, one-size-fits-all answer.

By the B2 level, the learner's use of 'はい、そうです' is characterized by a high degree of naturalness, precision, and social calibration. They possess a deep understanding of Japanese pragmatics and can seamlessly integrate the phrase into complex, fast-paced conversations. B2 learners rarely make the mistake of using it with verbs, and they instinctively know when a simple 'hai' or a nod is more appropriate than the full phrase, avoiding the robotic overuse common in lower levels. They also begin to encounter and actively use more advanced synonyms and related expressions, such as 'その通りです' (sono toori desu) for emphatic agreement or 'おっしゃる通りです' (ossharu toori desu) when speaking respectfully to superiors. In professional or academic settings, they use 'はい、そうです' confidently to confirm complex data, clarify misunderstandings, and validate the statements of others. Their pronunciation and intonation perfectly mimic native speakers, allowing them to convey subtle emotional undertones—such as enthusiasm, reluctance, or professional detachment—simply through the way they articulate the phrase.

At the C1 level, learners have mastered the entire spectrum of Japanese affirmative expressions, and 'はい、そうです' is just one tool in a vast, highly refined communicative arsenal. They operate effortlessly in high-level business, academic, and formal social environments, where the choice of words carries significant weight. C1 learners understand the historical and cultural underpinnings of Japanese politeness (Keigo) and can effortlessly transition from 'sou desu' to the highly formal '左様でございます' (sayou de gozaimasu) when dealing with VIP clients or in formal hospitality settings. They use these phrases not just to communicate facts, but to actively manage social harmony (Wa), demonstrate profound respect, and navigate complex hierarchical relationships. They are also adept at using the phrase rhetorically or strategically in debates or negotiations, perhaps using a slow, measured 'hai, sou desu' to concede a minor point before presenting a counterargument. Their usage is indistinguishable from an educated native speaker, characterized by flawless timing, perfect contextual appropriateness, and deep cultural resonance.

At the C2 level, the learner possesses a near-native, intuitive mastery of 'はい、そうです' and all its variations, encompassing the deepest subtleties of Japanese pragmatics, sociolinguistics, and cultural psychology. They understand how the phrase functions not just linguistically, but as a reflection of the Japanese high-context communication style, where what is left unsaid is often as important as what is spoken. C2 learners can manipulate the phrase to achieve highly specific communicative goals—using it ironically, humorously, or to subvert expectations in literary or creative contexts. They are fully capable of analyzing the phrase's usage in classic literature, contemporary media, and regional dialects, understanding how its pronunciation and application might shift across different demographics and regions of Japan. They can seamlessly code-switch between the absolute highest levels of Sonkeigo (respectful language) and the most intimate, localized slang, always knowing exactly where 'sou desu' fits on the spectrum. For the C2 learner, the phrase is a transparent medium through which they express their complete integration into Japanese linguistic culture.

연습하기 예시 노트와 팁

はい、そうです 30초 만에

Means 'Yes, that is right' or 'Yes, it is'.
Used to politely confirm facts or states of being.
Cannot be used to answer questions involving action verbs.
Essential for basic, polite Japanese communication.

The Japanese phrase 'はい、そうです' (hai, sou desu) is one of the most fundamental and ubiquitous expressions in the Japanese language, serving as the standard, polite way to affirm a statement, answer a yes-or-no question affirmatively, or express agreement with an interlocutor's assessment of a situation. To truly understand its meaning, we must break down its constituent parts and examine how they function together to create a seamless expression of agreement. The first component, 'はい' (hai), is typically translated as 'yes,' but its pragmatic function in Japanese extends far beyond simple affirmation. It acts as an acknowledgment, a marker of active listening, and a signal of respect toward the speaker. When used in isolation, 'hai' simply means 'I hear you' or 'I understand,' which is why it is often paired with 'そうです' to explicitly confirm the factual accuracy of a statement. The second component, 'そう' (sou), is a demonstrative adverb meaning 'so' or 'in that way.' It belongs to the ko-so-a-do series of demonstratives and specifically refers to something that is closer to the listener than to the speaker, or something that has just been mentioned in the conversation. By using 'sou,' the speaker is pointing directly to the listener's previous statement. Finally, 'です' (desu) is the polite copula, roughly equivalent to the English 'is,' 'am,' or 'are.' It elevates the register of the sentence, making it appropriate for interactions with acquaintances, colleagues, superiors, or strangers. Therefore, the literal translation of 'はい、そうです' is 'Yes, it is that way,' which naturally translates to 'Yes, that is right' or 'Yes, it is' in English. This phrase is indispensable for learners because it forms the backbone of polite, affirmative communication in Japanese society.

Literal Translation: Yes, it is that way.

Pragmatic Meaning: I completely agree with what you just said, and I confirm its factual accuracy.

Register: Polite (Teineigo), suitable for most everyday interactions.

Are you a student? はい、そうです.

Is this your umbrella? はい、そうです.

Is the meeting at 3 PM? はい、そうです.

Are you Mr. Tanaka? はい、そうです.

Is it raining outside? はい、そうです.

Understanding the profound simplicity of this phrase is the first step toward mastering Japanese conversational dynamics. It provides a reliable, universally understood mechanism for establishing mutual understanding and moving a dialogue forward without unnecessary friction or ambiguity.

Using 'はい、そうです' correctly requires an understanding of Japanese conversational structures, particularly the distinction between confirming a state of being versus confirming an action. This phrase is exclusively used to answer questions that end in a noun or an adjective followed by the copula 'desu' (or its informal equivalent 'da'). For example, if someone asks 'Nihonjin desu ka?' (Are you Japanese?), the appropriate response is 'Hai, sou desu' because the question is asking about a state of being or an identity. However, if someone asks 'Nihon ni ikimasu ka?' (Are you going to Japan?), you cannot answer with 'Hai, sou desu.' Instead, you must repeat the verb: 'Hai, ikimasu' (Yes, I am going). This is a crucial grammatical boundary that many beginners struggle with, as English allows 'Yes, I am' or 'Yes, I do' for both types of questions. Furthermore, 'はい、そうです' plays a vital role in the Japanese concept of 'Aizuchi,' which refers to the frequent interjections listeners make to show they are paying attention. While 'hai' alone is the most common Aizuchi, adding 'sou desu' elevates the interjection from mere acknowledgment to active agreement. When a speaker is explaining a complex situation, the listener might interject with 'sou desu, sou desu' (often dropping the 'hai' in rapid conversation) to enthusiastically validate the speaker's points. In formal settings, maintaining the full 'はい、そうです' demonstrates respect and attentiveness.

Noun Questions: Perfectly appropriate. Example: 'Is this a pen?' -> 'Yes, it is.'

Verb Questions: Incorrect usage. You must repeat the verb instead of using 'sou desu'.

Adjective Questions: Generally acceptable, but repeating the adjective is often more natural.

Is that your car? はい、そうです.

Are you the new employee? はい、そうです.

Is the capital of Japan Tokyo? はい、そうです.

Is this the train to Shinjuku? はい、そうです.

Are you American? はい、そうです.

Mastering the contexts in which this phrase is appropriate will significantly improve your conversational fluency and prevent awkward misunderstandings when interacting with native Japanese speakers.

The phrase 'はい、そうです' is ubiquitous across virtually all domains of Japanese life, from the highly formalized environment of corporate boardrooms to the casual interactions of daily commerce. In a business context, it is the standard, polite way to confirm details with clients, superiors, or colleagues. For instance, if a manager asks, 'Is the report finished?' (assuming the question is phrased with a noun state, like 'Kansei desu ka?'), the subordinate will promptly reply, 'Hai, sou desu.' It projects competence, clarity, and respect. In customer service scenarios, such as at a restaurant or a retail store, shop staff frequently use this phrase to confirm orders or answer customer inquiries about products. If a customer points to a pastry and asks, 'Is this matcha flavored?' the clerk will respond with a bright, polite 'Hai, sou desu.' In educational settings, students use it to answer teachers' questions, and teachers use it to validate students' correct answers. Furthermore, you will hear it constantly in Japanese media, including television dramas, anime, news interviews, and talk shows. It serves as a structural pillar of dialogue, allowing characters to quickly establish facts and move the plot forward.

Business Meetings: Used to confirm data, schedules, and factual inquiries from colleagues and bosses.

Customer Service: Used by staff to politely confirm customer questions about items or services.

Everyday Life: Used with neighbors, acquaintances, and strangers to confirm simple facts.

Is this the line for the register? はい、そうです.

Did you drop this wallet? はい、そうです.

Is the doctor available now? はい、そうです.

Is this your first time in Japan? はい、そうです.

Are these documents for the presentation? はい、そうです.

Because it is so common, learners will have ample opportunity to hear and practice this phrase in real-world environments, making it one of the most quickly acquired and frequently utilized expressions in a beginner's vocabulary.

Despite its apparent simplicity, learners frequently make subtle but significant errors when using 'はい、そうです'. The most prevalent mistake, as mentioned earlier, is using it to answer questions that involve action verbs. If someone asks, 'Kinoo, eiga o mimashita ka?' (Did you watch a movie yesterday?), answering with 'Hai, sou desu' sounds incredibly unnatural to a native speaker. The correct response is 'Hai, mimashita' (Yes, I watched it). 'Sou desu' specifically replaces a noun phrase, not a verb phrase. Another common error is overusing the phrase when a simple 'hai' would suffice. While 'hai, sou desu' is polite, using it to respond to every single statement in a conversation can make the speaker sound robotic, overly formal, or even dismissive, as if they are mechanically confirming facts rather than engaging in a fluid dialogue. Native speakers naturally mix 'hai,' 'ee,' 'sou desu ne,' and simple nods to create a rhythmic flow. Furthermore, learners sometimes confuse 'sou desu' with 'sou desu ne.' While 'sou desu' is a definitive statement of fact ('Yes, that is right'), 'sou desu ne' (with the particle 'ne') is used to express empathetic agreement, thoughtfulness, or to buy time while thinking ('That is right, isn't it?' or 'Let me see...').

Verb Confusion: Using it to answer 'Do you eat sushi?' instead of repeating the verb 'eat'.

Overuse: Sounding robotic by using it for every single affirmative response in a long conversation.

Particle 'Ne' Omission: Failing to add 'ne' when you actually mean to express shared empathy rather than cold factual confirmation.

Incorrect: Will you go? はい、そうです.

Correct: Will you go? Hai, ikimasu.

Incorrect: Is it delicious? はい、そうです. (Better: Hai, oishii desu)

Correct: Are you a teacher? はい、そうです.

Correct: Is this Tokyo? はい、そうです.

By consciously avoiding these common pitfalls, learners can ensure their Japanese sounds natural, contextually appropriate, and socially calibrated to the situation at hand.

The Japanese language is rich with varied expressions of agreement, each carrying its own distinct nuance, level of politeness, and contextual appropriateness. While 'はい、そうです' is the standard, polite baseline, understanding its synonyms and related phrases is essential for achieving fluency and expressive depth. One of the most common variations is 'そうですね' (sou desu ne). While it translates similarly, the addition of the particle 'ne' shifts the meaning from a cold confirmation of fact to a shared, empathetic agreement. It is often used to agree with an opinion rather than a hard fact (e.g., 'It's hot today, isn't it?' -> 'Sou desu ne'). Another highly useful phrase is 'その通りです' (sono toori desu), which translates to 'That is exactly right' or 'Just as you said.' This is a stronger, more emphatic form of agreement, often used when someone has perfectly summarized a complex situation or deduced a correct conclusion. In casual speech, 'はい、そうです' transforms into 'うん、そう' (un, sou) or 'そうだよ' (sou da yo), which are used exclusively with close friends and family. Conversely, in hyper-formal business or customer service settings, you will hear 'はい、左様でございます' (hai, sayou de gozaimasu), which is the sonkeigo (respectful language) equivalent.

そうですね (Sou desu ne): Empathetic agreement, used for shared opinions or observations.

その通りです (Sono toori desu): Emphatic agreement, meaning 'That is exactly right' or 'Spot on.'

左様でございます (Sayou de gozaimasu): Extremely formal agreement, used in high-level business or hospitality.

Casual: うん、そうだよ.

Empathetic: そうですね.

Emphatic: その通りです.

Formal: 左様でございます.

Standard: はい、そうです.

By carefully selecting the appropriate variation of agreement based on the social hierarchy, the nature of the conversation, and the desired emotional resonance, learners can navigate Japanese social interactions with grace and precision.

はい、そうです vs

문장 패턴

사용법

nuance

Definitive, factual confirmation. Lacks the emotional empathy of 'sou desu ne'.

formality

Polite (Teineigo). Safe for use with strangers, teachers, and colleagues.

restrictions

Cannot be used to answer verb-based questions.

자주 하는 실수

Using it to answer verb questions (e.g., Q: 行きますか？ A: はい、そうです -> Incorrect).
Confusing it with 'そうですね' when agreeing with an opinion about the weather or food.
Using it to accept an invitation (e.g., Q: 映画を見ませんか？ A: はい、そうです -> Incorrect).
Using it with close friends, which sounds overly formal and distant.
Pronouncing 'sou' with a short 'o' instead of a long 'o' (so-o).

팁

The Verb Rule

Never use 'sou desu' to answer a question ending in '-masu'. If the question is 'Nomi-masu ka?' (Will you drink?), answer 'Nomi-masu'. Only use 'sou desu' for questions ending in 'desu ka'.

Elongate the 'O'

Make sure to pronounce 'sou' with a long 'o' sound (so-o). If you cut it short, it sounds unnatural. It should take two 'mora' (beats) to say 'sou'.

The Power of the Nod

In Japanese, verbal agreement is almost always accompanied by physical agreement. A slight, crisp nod of the head while saying 'hai, sou desu' makes you look instantly more fluent and culturally aware.

Facts vs. Opinions

Remember the golden rule: 'sou desu' is for confirming hard facts (names, times, places). 'Sou desu ne' is for agreeing with opinions (weather, feelings, subjective thoughts).

Listen for 'Sou desu ka'

Don't confuse 'sou desu' (Yes, it is) with 'sou desu ka' (Is that so? / I see). The rising intonation and the 'ka' particle completely change the meaning from an answer to an acknowledgment.

Know Your Audience

Use 'hai, sou desu' with teachers, colleagues, and strangers. Switch to 'un, sou' with your friends. Using polite forms with close friends creates an awkward, invisible wall between you.

Punctuation Matters

When writing this phrase, always put a Japanese comma (、) after 'hai'. It represents the natural micro-pause native speakers take before confirming the statement. 'はい、そうです。'

Upgrade to 'Sono toori'

Once you master 'sou desu', try using 'sono toori desu' (That is exactly right) when someone makes a really good point. It shows a higher level of vocabulary and enthusiastic agreement.

Don't Overuse It

Beginners often sound like robots by answering every single question with 'hai, sou desu'. Mix it up. Sometimes just say 'hai'. Sometimes repeat the noun. Variety is the key to natural speech.

Aizuchi Mastery

Understanding 'sou desu' is your gateway to Aizuchi (backchanneling). Japanese conversations are a two-way street where the listener must constantly prove they are listening. This phrase is your best tool for that.

자주 묻는 질문

10 질문

Yes, you can. In Japanese, 'like' (suki) is an adjective, not a verb. The question is 'Sushi ga suki desu ka?' Because it ends with an adjective + desu, 'sou desu' is grammatically acceptable. However, repeating the adjective ('Hai, suki desu') is often considered more natural. Still, 'sou desu' is not incorrect here.

Because 'going' (ikimasu) is an action verb. 'Sou desu' literally means 'it is that way' and is used to replace noun states. You cannot say 'Yes, it is that way' to an action. You must repeat the verb: 'Hai, ikimasu' (Yes, I will go). This is a strict grammatical rule in Japanese.

'Sou desu' is a cold, factual confirmation. It means 'Yes, that fact is correct.' 'Sou desu ne' includes the particle 'ne', which seeks or expresses shared emotion. It means 'That's right, isn't it?' or 'I agree with your opinion.' Use 'sou desu' for facts, and 'sou desu ne' for opinions or observations.

No, 'hai' is not rude. In fact, it is the most common way to say yes. However, adding 'sou desu' makes the response slightly more polite, definitive, and complete. If someone asks a very direct question about your identity, 'hai, sou desu' sounds more professional and attentive than a brief 'hai'.

To a close friend or family member, you drop the polite copula 'desu' and often change 'hai' to 'un'. The most common casual forms are 'うん、そう' (un, sou) or 'うん、そうだよ' (un, sou da yo). Never use 'sou desu' with close friends, as it sounds unnaturally stiff and distant.

No. If someone says 'Let's go to the movies' (Eiga ni ikimashou), you cannot say 'Hai, sou desu.' That would mean 'Yes, it is a movie.' To agree to an invitation, you should say 'Hai, ikimashou' (Yes, let's go) or 'Ii desu ne' (That sounds good).

The standard negative equivalent is 'いいえ、違います' (iie, chigaimasu), which literally means 'No, it is different' or 'No, that is wrong.' Another option is 'いいえ、そうではありません' (iie, sou de wa arimasen), which literally means 'No, it is not that way,' but 'chigaimasu' is much more common in daily conversation.

Not always. In a fast-paced conversation, native speakers often drop the 'hai' and simply say 'そうです' (sou desu). This is still polite but feels slightly more conversational and less rigid. However, beginners are encouraged to use the full phrase until they get a feel for the rhythm of the language.

In highly formal situations, such as speaking to a very important client or in high-end customer service, 'sou desu' is elevated to '左様でございます' (sayou de gozaimasu). This is the sonkeigo (respectful language) equivalent. It carries the exact same meaning but shows the highest level of deference.

Repeating 'sou' rapidly is a very common casual Aizuchi (backchanneling). It means 'Yes, exactly!' or 'Right, right, right!' It shows enthusiastic agreement with what the speaker is saying. However, this rapid repetition is strictly casual and should not be used with superiors or in formal settings.
