The こそあど family has one branch that behaves like an adverb rather than a pronoun: こう, そう, ああ, どう. Where これ・それ・あれ point at things and この・その・あの attach to nouns, this set points at ways of doing things — "like this," "like that," "how." They modify verbs and whole clauses. One of them, そう, is quietly one of the most-used words in all of spoken Japanese, so this small four-member set repays very close attention.
The four forms at a glance
The manner series maps cleanly onto the こ・そ・あ・ど distances you already know: こ- is the speaker's sphere, そ- is the listener's or the just-described, あ- is distant/recalled, and ど- is the question.
| Form | Reading | Core meaning | Typical partners |
|---|---|---|---|
| こう | kō | this way, like this | こうする, こうやって, こう書く |
| そう | sō | that way, so, like that | そう思う, そうする, そうです |
| ああ | ā | like that (distant / recalled / abstract) | ああいう, ああする, ああ言う |
| どう | dō | how, in what way | どうする, どうやって, どうですか |
Note the long vowels: every one of these is a long syllable (kō, sō, ā, dō), never a short "ko/so/a/do." Clipping them short is one of the fastest ways to sound non-native.
こう — the way I'm showing you
こう describes doing something the way the speaker is demonstrating, or is about to demonstrate. It clings to verbs of doing and making: する, やる, 書く（かく, to write）, 言う（いう, to say）.
こうやってください。
kō yatte kudasai
Please do it like this.
この漢字、こう書くんですか？
kono kanji, kō kaku n desu ka?
This kanji — do you write it like this?
こう見えて、彼はもう六十歳なんだ。
kō miete, kare wa mō rokujussai nan da
Believe it or not, he's already sixty.
That last one is a set phrase — こう見えて（みえて）literally "looking this way" — meaning "despite how it/I/he look(s)." It shows how こう can refer to the whole visible situation, not just a hand gesture.
そう — the workhorse of agreement
On paper そう simply means "that way / so," pointing to a manner already on the table — one just described, or one in the listener's world. In practice, そう is the single busiest word in Japanese conversation, because it is the backbone of agreeing, confirming, and reacting.
私もそう思います。
watashi mo sō omoimasu
I think so too.
これでいいですか？ ― はい、そうです。
kore de ii desu ka? — hai, sō desu
Is this okay? — Yes, that's right.
Here そうです does not mean "it is that way" in any literal sense — it is the standard way to confirm a whole proposition: "correct / that's the case." When someone asks 田中（たなか）さんですか？("Are you Tanaka?"), the native reply is はい、そうです, not a repeated verb.
The reactions built on そう are endless, and you will hear them every few seconds:
明日、休みなんだって。 ― へえ、そうなんだ。
ashita, yasumi nan datte — hē, sō nan da
Apparently tomorrow's a day off. — Oh, is that so.
そうそう、それが言いたかったの！
sō sō, sore ga iitakatta no!
Yes, exactly — that's what I wanted to say!
そう also builds the adnominal そういう ("that kind of," modifying a noun) — parallel to そんな. When you need to describe a type rather than a manner, reach for そういう / そんな instead; see こんな・そんな・あんな.
ああ — like that, over there and long ago
ああ is the distal member: it points to a manner removed from the here-and-now — physically distant, abstract, or (very often) recalled from memory the speaker assumes the listener shares. Its most common shape is ああいう ("that kind of," distant).
ああいう人には気をつけたほうがいいよ。
ā iu hito ni wa ki o tsuketa hō ga ii yo
You'd better watch out for people like that.
若い頃は、よくああやって遊んだなあ。
wakai koro wa, yoku ā yatte asonda nā
When we were young, we used to mess around like that, didn't we.
That second sentence leans on shared memory — "like that" refers to a way of behaving both speaker and listener remember. This memory-based use of the あ-series is central to intimate conversation and is covered in depth in こそあ in discourse.
どう — the question member
どう asks "how / in what way." It is the interrogative anchor of the set: どうする ("what'll you do"), どうやって ("by what means"), どうですか ("how is it / how about"), and the everyday cry of dismay どうしよう.
どうしよう、財布を忘れちゃった。
dō shiyō, saifu o wasurechatta
What do I do — I forgot my wallet.
週末はどうでしたか？
shūmatsu wa dō deshita ka?
How was your weekend?
これ、どうやって食べるんですか？
kore, dō yatte taberu n desu ka?
How do you eat this?
どう has a wide reach — it also means "how about" in suggestions (コーヒーはどう？) and hides inside どうして and どうも. Its full range is mapped in どう・どんな・どうして.
Why English speakers under-use そう
English has no dedicated "manner demonstrative." We say "do it like this," "I think so," "that kind of thing" — recycling the same this/that/so used for objects. Japanese instead has a purpose-built adverb series, and crucially it front-loads agreement onto そう. English speakers, translating word-for-word, keep grabbing これ (a thing) when they mean こう (a way), and answer confirmation questions with a verb ("yes, I am") instead of the ready-made そうです. Rewiring these two habits closes a large part of the gap between textbook Japanese and the real thing.
Common Mistakes
❌ この書いてください。
Incorrect — この is adnominal ('this ___'), it can't mean 'this way'.
✅ こう書いてください。
kō kaite kudasai
Please write it like this.
❌ 田中さんですか？ ― はい、います。
Incorrect — grabbing a verb ('I exist') to confirm your identity, an English-style 'yes, I am'.
✅ 田中さんですか？ ― はい、そうです。
Tanaka san desu ka? — hai, sō desu
Are you Tanaka? — Yes, that's right.
❌ どう映画が好きですか？
Incorrect — どう is 'how', an adverb; it cannot attach to a noun like 映画.
✅ どんな映画が好きですか？
donna eiga ga suki desu ka?
What kind of movies do you like?
❌ 私はそう思いません。
Understandable but unnatural — negating そう with a bare 思いません sounds blunt.
✅ 私はそうは思いません。
watashi wa sō wa omoimasen
I don't think so.
The last pair is subtle: when you negate そう思う, natives normally insert は (そうは思いません), because は naturally marks the negated element for contrast. Say it the short way and it lands abruptly — fine among friends, jarring in a discussion.
Key Takeaways
- こう・そう・ああ・どう are manner adverbs ("this way / that way / like that / how"), not pronouns; they modify verbs, not nouns.
- All four are long vowels — kō, sō, ā, dō.
- そう is the hub of agreement and back-channeling (そうです, そうですね, そうそう, そうなんだ). Learning to deploy it fluently is the fastest route to natural-sounding conversation.
- Confirm a whole statement with そうです, not by echoing a verb.
- The hearsay/appearance そうだ is a different, homophonous suffix — don't mix it up with the manner adverb.
