第??課: Yes Phrases: Hai はい,  はあ, Ē  ええ, & Un うん

Way back in Lesson 7, we learned briefly that the words for “yes” and “no” were hai はい and iie いいえ respectively. However, it couldn’t be further from the truth that this is all you need to know to use these two words correctly, or even to express “yes” and “no” correctly in every circumstance. These words, aside from being literal replies to yes-no questions, can also be used as aizuchi 相槌 in back-channeling, where one interjects to indicate that one is paying attention.

Incidentally, a lot can be said about both the words for “yes” and about the words for “no.” Meaning, there are several ways to go about saying both, and each word brings along with it usages that you may not necessarily think of as an English speaker. In this lesson, we will focus solely on the words that translate as “yes.”

Hai はい
Ē ええ
Un うん

Curriculum Note: Because these words, at times, require context to be understood, there will be some grammar used that has not been formally introduced. At those points, simply focus on understanding the yes-phrase at hand. 

The Usages of Hai はい・ はあ

1. The most fundamental usage of hai はい is meaning "yes" in answering “yes-no” questions

1. 「はい」を()してください。
“Hai” wo oshite kudasai.
Please press “Yes.”


Ei-shi: Ashita, kaimono ni ikimasu ka?
Bii-shi: Hai(, Kosutoko ni kaimono (shi) ni ikimasu).
Person A: Are you going to go shopping tomorrow?
Person B: Yes(, I’m going to go shop at Costco).

Although simply saying hai はい could suffice in answering a yes-no question, explicitly stating an answer is often needed because this isn’t the only function hai はい has. Tone, for one, is very important. If one’s tone doesn’t convey affirmation, then hai はい won’t likely be interpreted as a simple “yes.” Also, if you are speaking to a superior/client where giving a succinct answer is expected, just answering with hai はい would be inappropriate. The same could be said in the English-speaking business world if one were to continuously say “yes” without providing anything substantive.

2. Hai はい also shows confirmation, which is in and of itself an offshoot of above. If the question is in the affirmative, hai はい confirms the affirmative. However, if it the question is in the negative, hai はい confirms the negative. This is unlike English where the latter situation would be answered with “no.”


Ei-shi: Kotoshi Sesu wa nijūyonsai ni narimasu ne.
Bii-shi: Hai(, sō desu ne).

Person A: Seth turns 24 this year, right?
Person B: Yes(, that’s right).

Phrase NoteSō desu ne そうですね and its variants can often be treated as beings synonymous to “yes” and do not need to be used with a yes-word to be used as such. This is no different than the English expression “that’s right.”


Ei-shi: Asu, Kyōto e ikanai n desu ka?
Bii-shi: Hai, ikimasen ne. Tabun kotoshi wa ikanai to omoimasu.

Person A: Are you not going to Kyoto tomorrow?
Person B: No, I’m not. I probably won’t go this year.


Sachiko: Yasumu n desu ka?
Yasuhiko: Hai, chotto kyū na yoji ga arimashite.

Sachiko: Are you taking the day off?
Yasuhiko: Yes, I have an urgent thing to attend to.  


Dōryō Ei: Ikanai n desu ka?”
Dōryō Bii: Hai, ikimasen.

Colleague A: Are you not going?
Colleague B: No, I’m not going.

3. Hai はい may also show agreement to a request, in which case it is accompanied with an affirmative tone. This can also be viewed as an offshoot of answering to a yes-no question, only with “no” not being an option.


Kachō: Kono fairu wo Tsuji-san ni tensō shite kudasai.
Shain: Hai(, shōchi shimashita).

Section Manager: Please forward these files to Tsuji-san.
Employee: Yes(, understood).

8. はい、わかりました。
Hai, wakarimashita.

Phrase Note: The phrases for "understood" are listed below in order of how polite/humble they are.

 Most Humble Kashikomarimashita 畏まりました
 Very Humble Shōchi itashimashita 承知いたしました
 Humble Shōchi shimashita 承知しました
 Polite (To those equal or below oneself) Ryōkai shimashita 了解しました
 Polite (General-Use) Wakarimashita わかりました
 Polite (To equals) Ryōkai desu 了解です
 Casual Wakatta わかった・Ryōkai 了解

4. Hai はい is the go-to phrase when responding to someone calling (for) you, both in person and on the phone.


Fujita: Kaneko-san.
Kaneko: Hai.
Fujita: Kochira ni kite moratte ii desu ka?

Fujita: Kaneko-san.
Kaneko: Yes.
Fujita: Could you please come here?


母親(ははおや):もしもし。 (電話(でんわ)
Hahaoya: Moshimoshi. (Denwa)
Musume: Hai. A, o-kā-san!

Mother: Hello. (Phone)
Daughter: Hello. Oh, mom!

5. Another usage of hai はい is to indicate the start of a joint activity.

11. では、調理開始(ちょうりかいし)ですね、はい。
De wa, chōri kaishi desu ne, hai.
Well then, cooking begins. Yes. 

12. これをあのベンチに()いときましょう。ちょっと(おも)いので()をつけましょう。じゃ、いち、にいの、さん、はい!
Kore wo ano benchi ni oitokimashō. Chotto omoi node ki wo tsukemashō. Ja, ichi, nii no, san, hai!
Let’s place this on the bench over there. It’s a little heavy, so let’s be careful. Alright, one, two, three, here we go!

6. One usage of hai はい that is far removed from the English concept of “yes” is indicating to the speaker that one is listening. The purpose here is not to interrupt who is talking, which is how it may seem to an English speaker. Once the other person is done speaking, however, simply responding with hai はい would be inappropriate as its interpretation would default to this usage.


Ei-shi: Tsugi no gurafu wo mite morau to.
Bii-shi: Hai.
Ei-shi: Wakaru to omoimasu ga.
Bii-shi: Hai.

Person A: If I have you look at the next graph.
Person B: Mm.
Person A: I believe you’ll understand, but…
Person B: Mm.

It may not always be the case that one is the intended listener when using hai はい in this fashion. This is especially the case in TV programs where one person may be directing comments to the audience while another person is to the side nodding off and making interjections as the person speaks. This is done largely to encourage engagement from the audience.

The applications of this usage thus far have been harmless, but it can also be used to tell the speaker you’ve heard enough.

14. はいはい、もう()かってますよ。
Hai hai, mō wakattemasu yo.
Yes, yes, I know already.

With a change in intonation to that of a question, hai はい can be used when you would otherwise indicate that you’re listening to imply that you’re shocked by what is said—simultaneously asking that the speaker repeat oneself.

Come again?

7. Responding to sō desu ka? そうですか is an important function of hai はい.


Ryōko: Kinō, Shirakobato Suijō Kōen ni ikimashita yo.
Sara: A, sō desu ka?
Ryōko: Hai, sugoku tanoshikatta desu yo. Zehi itte mite kudasai.

Ryoko: I went to Shirakobato Water Park yesterday.
Sara: Oh, really?
Ryoko: Yeah, it was really fun. Definitely try going there.

8. Hai はい is often used as an anticipatory answer at the end of a sentence, especially by store clerks.


Kyaku: Ima no shun no shokuzai wa nan deshō ka?
Tenchō: So desu nē. Ima no jiki, oishii sakana wa ippai aru n desu kedo, toku ni oishii no wa yappari tai desu ne, hai.
Customer: What ingredients are in season now?
Shop Manager: Well, there are a lot of delicious fish this season, but the one that’s especially delicious would have to be sea bream. Yes.

9. Hai はい is used when presenting something to someone. This can also be said when arriving somewhere, with the destination being what one is bringing attention to.

18. はい、()()みご(はん)です。どうぞ。
Hai, takikomi-gohan desu. Dōzo.
Here’s mixed rice. Feel free.

19. はい、こちらはスターバックスコーヒー1(いち)号店(ごうてん)でございます。
Hai, kochira wa Sutābakkusu Kōhii Ichigōten de gozaimasu.
Now right here is Starbucks Coffee’s first store.

20. はい、到着(とうちゃく)しました。
Hai, tōchaku shimashita.
Alright, we’ve arrived.

10. Hai はい is frequently used right as one is giving instructions.

21. はい、スタート!
Hai, sutāto!

22. はい、冷蔵庫(れいぞうこ)()れて。
Hai, reizōko ni irete.

11. Hai はい is used to indicate to others they stop what they’re doing. 

23. はい、そこまで(だ)!
Hai, soko made (da)!
Alright, stop there!


Seito Ei: Watashi wa shōrai uchū-hikōshi ni naritai desu!
Sensei: Hai. Ja, Kenta-kun wa?

Student A: I want to become an astronaut in the future!
Teacher: Alright. Now how about you, Kenta-kun?

12. Hai はい can also be used to get people’s attention.

25. 先生(せんせい):はい、はい。みな()()いてください。
Sensei: Hai, hai. Mina ochitsuite kudasai.
Okay, okay, everyone settle down, please.

13. Hai はい is frequently used in response to being asked for commentary.


Saitō: Katō-san, dō omoimasu ka?
Katō: Hai, ano, watashi mo hantai desu ne.

Saito: What do you think, Kato-san?
Kato: Yes, um, I’m also against it.

14. Hai はい is also frequently used after someone makes a comment to get the individual to say more. This can be viewed as an offshoot of Usage 6.


Higaisha: Watashi wa ao ni kawatta no wo kakunin shite kara chokushin ni hassha sasemashita.
Kensatsukan: Hai.
Higaisha: Hai, sono ato, hidarigawa kara kuruma ga miete burēki wo fumimashita ga, ma ni awazu jiko ni narimashita.
Kensatsukan: Hai.
Higaisha: Sono toki, taikōsha wa ichidai deshita.

Injured Party: I went straight in my car after verifying that the light had turned green.
Prosecutor: Continue.
Injured Party: Ok, afterward, I could see a car from the left. I braked but didn’t make it in time, which led to the accident.
Prosecutor: Continue.
Injured Party: At that time, there was one oncoming car. 

15. At times, hai はい is simply used to create a rhythm, especially in folk songs. It may also be used as an interjection when pounding mochi 餅 (sticky rice cake).  

28. はい、はい、はい、はい。
Hai, hai, hai, hai.
One, two, one, two. 

Variation Note: There also exists hā はあ, which is treated as a simple alteration of hai はい that is used by male speakers, but its usage remains exactly the same.

29. はあ、承知(しょうち)しました。
Hā, shōchi shimashita.
Yes, understood.

30. はあ!
Yes, sir!

31. はあ、その地震(じしん)大変(たいへん)でしたね。
Hā, sono jishin wa taihen deshita ne.
Yeah, that earthquake was terrible, huh.

32. はあ、なんでしょうか。
Hā, nan deshō ka?
Yes, what is it?

33. はあ、それはそうですが。
Hā, sore wa sō desu ga.
Yes, that’s true, but…

34. はあ、(うそ)でしょう?
Hā, uso deshō?
What, you’ve got to be kidding!?

35. はあ、しまった!
Hā, shimatta!
Ah, damn it!

Usage Note: One usage that はあ has that it doesn’t share with hai はい is being used as an interjection when one is really in a rut over failing at something, etc.

The Usages of Ē ええ

Hai はい is the most multi-faceted word used in this lesson. It is also the most formal. With that being said, ē ええ is not as complicated. Regardless of how it’s used, it is an affirmative response of one’s thought and/or emotions, which is why it can at times be perceived as rude if used out of place. Below are various scenarios most suited for using ē ええ:

・To show confidence.
・To make it known that you already know about what’s been talked about.
・Indicative of being older, composed, and being able to affirmatively look back.
・To show elitism.
・To give an at-home feeling to those especially close.
・Responding to audience but without appeal unless mixed together with hai はい.
・Seemingly able to talk on and on, indicative of female conversation.
