そうです has two meanings: "it looks like" and "I heard

There are two completely separate そう in Japanese: one says "it looks like it's about to," the other says "I heard that." They are told apart by what shape the word in front takes — not by context, and not by tone.

あめりそうです。 — It looks like it's going to rain. (I'm looking at the sky) あめるそうです。 — I hear it's going to rain. (someone told me)

One syllable apart. Different evidence, different meaning, and no way to recover if you pick the wrong one. This is one of the few places in Japanese grammar where a small slip produces a sentence that is fully grammatical and simply says something you did not mean.

The basics

The first そう: "it looks like"

This one reports what your eyes are telling you. You are looking at something and making a guess from its appearance.

How to attach it:

Word type Rule Example
Verb ます-stem + そう る → そう
い-adjective drop い + そう おいしい → おいしそう
な-adjective attach directly 元気げんき元気げんきそう
いい irregular よさそう
ない irregular なさそう

おいしそうですね。 — That looks delicious. (you haven't tasted it yet) このほんむずかしそう。 — This book looks hard. (casual, judging by the cover) 元気げんきそうですね。 — You look well. (polite, a normal greeting to someone you haven't seen in a while)

With verbs it usually means "about to happen" rather than "appears to be":

あめりそうです。 — It looks like it's about to rain. きそう。 — I'm about to cry. (casual)

This そう behaves like a な-adjective afterwards, which is the second thing to learn about it:

おいしそうな料理りょうり — Food that looks delicious. (before a noun: そうな) おいしそうにべる。 — To eat as if it's delicious. (before a verb: そうに)

The second そう: "I heard"

This one reports information you received. You are not guessing — you are passing something on.

How to attach it: take the plain form of the sentence, in any tense, and add そうです. Nothing changes shape.

Word type Example
Verb る → そうです
Verb, past った → ったそうです
い-adjective たかい → たかそうです
な-adjective しずかだ → しずかだそうです
Noun 学生がくせいだ → 学生がくせいそうです

田中たなかさんはないそうです。 — I hear Tanaka isn't coming. あのみせたかいそうです。 — I hear that shop is expensive. 天気予報てんきよほうによると、明日あしたゆきだそうです。 — According to the forecast, tomorrow will be snow.

Notice that な-adjectives and nouns keep their だ here. しずかだそうです, 学生がくせいだそうです. That だ is exactly what tells you this is the hearsay そう — the plain form is the giveaway.

And unlike the first そう, this one never conjugates. There is no 〜そうな料理りょうり meaning "food I heard about," and no 〜そうに. If you see そうな or そうに, it is always the "looks like" そう.

The one test that separates them

Look at the word immediately in front of そう and ask what shape it is in.

In front of そう Which そう Meaning
ます-stem (り, べ, き) Appearance about to / looks like
Plain form (る, べる, く) Hearsay I heard
い-adjective without い (たか, おいし) Appearance looks
い-adjective with い (たかい, おいしい) Hearsay I heard
Noun / な-adj with だ (学生がくせいだ, しずかだ) Hearsay I heard
Noun / な-adj without だ (元気げんき, しずか) Appearance looks

That is the entire distinction. It is mechanical, and once you can see it, the two stop blending together.

Beyond the basics

Why is it よさそう and not いいそう?

いい is irregular almost everywhere in Japanese, and this is one of those places. The old form よい is what actually conjugates, so:

このみせ、よさそうですね。 — This shop looks good. 時間じかんがなさそうです。 — It looks like there's no time.

ない follows the same pattern for the same reason: なさそう, not なそう. If you say いいそうです, a listener will parse it as hearsay — "I heard it's good" — which may not be what you meant.

How do you make the "looks like" version negative?

Three options, and they are not interchangeable.

おいしくなさそう。 — It doesn't look tasty. (negative adjective + そう) あめりそうにない。 — It doesn't look like it will rain. (そうにない — the standard negative for verbs) 間に合まにあいそうもない。 — There's no way we'll make it in time. (そうもない — stronger, more resigned)

For verbs, らなそう exists in casual speech but りそうにない is the form to produce. For adjectives, move the negative into the adjective itself: おいしくなさそう, not おいしそうじゃない — that last one means "it doesn't appear delicious" in a much narrower, odder sense.

When can you not use the "looks like" そう?

When the quality is directly visible. そう is for inference about something you cannot see straight on.

✗ このりんごはあかそうです。 。○ このりんごはあかいです。 — This apple is red.

Redness is not an inference — it is right there. Tastiness, difficulty, health, weight, expense: those are all inferred from appearance, so they take そう. Colour, shape, and size do not.

What about ようだ, みたい and らしい?

They overlap, and the differences are about where your evidence comes from:

Form Evidence Example
〜そう (appearance) What it looks like right now あめりそう
〜ようだ Reasoning from several clues あめったようだ (the ground is wet)
〜みたい Same as ようだ, casual あめったみたい
〜らしい Hearsay or reputation あめるらしい
〜そうだ (hearsay) A specific report you received 天気予報てんきよほうによるとあめるそうだ

らしい and hearsay そうだ are close. The difference is commitment: そうだ passes on a specific source faithfully, らしい is vaguer — "apparently," "from what I gather." A weather forecast gives you そうだ; an overheard rumour gives you らしい.

How does it sound in anime?

The "looks like" そう is everywhere in dialogue, usually shortened and emotional. If you watch with the sound on, these three will come up within the first episode of almost anything:

おいしそう! — That looks so good! にそう。 — I'm dying. (literally "about to die" — exhaustion, not danger) きそうだった。 — I was about to cry.

にそう is worth flagging: it almost never means actual danger. It is the standard exaggeration for hot, tired, hungry, or embarrassed, in exactly the way English uses "I'm dead."

Common mistakes

  • りそう vs るそう. ます-stem = you are looking at the sky. Plain form = someone told you. Getting this backwards produces a correct sentence with the wrong meaning, which nobody will correct.
  • いいそう for "looks good." It has to be よさそう. いいそう will be read as hearsay.
  • Dropping だ in hearsay. 学生がくせいそうです is wrong. Hearsay takes the plain form, so a noun keeps its だ: 学生がくせいだそうです.
  • Conjugating the hearsay そう. There is no そうな or そうに for hearsay. Those endings only exist on the appearance そう.
  • そう for visible qualities. あかそう, おおきそう for something right in front of you sounds strange — you can just see it. Use そう for what you are inferring, not for what you are observing.
  • おいしそうじゃない as the negative. Put the negative in the adjective: おいしくなさそう.

Practice

Answers are hidden — build yours first, then open. Questions 1 and 2 are a pair: one syllable moves, and the whole meaning goes with it.

1. What does あめりそうです mean, and what is your evidence?

Show answer

It looks like it's going to rain — you are looking at the skyり is the ます-stem, which is the appearance そう. Your own eyes are the source.

2. What does あめるそうです mean, and what is your evidence?

Show answer

I hear it's going to rain — someone told youる is the plain form, which is the hearsay そう. This is the pair to question 1: same words, different attachment, opposite source.

3. Say "this cake looks delicious."

Show answer

このケーキ、おいしそうです — drop the い from おいしい and add そう. You have not eaten it, so appearance is exactly right.

4. Something is wrong here: このみせはいいそうです(「よくえる」の意味いみで)。

Show answer

このみせはよさそうです — いい is irregular and becomes よさ before そう. いいそうです would be read as "I hear it's good."

5. Fill in: 田中たなかさんは学生がくせい( )そうです。("I hear Tanaka is a student.")

Show answer

学生がくせいだそうです。Hearsay attaches to the plain form, and a noun's plain form keeps だ. 学生がくせいそうです is not possible.

6. Say "it doesn't look like it's going to rain."

Show answer

あめりそうにありません / りそうにない — for verbs, the negative of appearance そう is そうにない, not そうじゃない.

7. Put おいしそう in front of a noun: "food that looks delicious."

Show answer

おいしそうな料理りょうり — appearance そう behaves like a な-adjective, so it takes な before a noun. Hearsay そう can never do this.

8. Why is このりんごはあかそうです strange?

Show answer

Redness is directly visible, not inferred — appearance そう is for guessing at something you cannot see straight on. Just say あかいです.

9. What does にそう usually mean in conversation?

Show answer

Exhausted, boiling, starving — not actual dangerに is the ます-stem, so it is "about to die," used exactly the way English says "I'm dead."

10. What is the difference between あめるそうだ and あめるらしい?

Show answer

How firm the source is — そうだ passes on a specific report faithfully (a forecast, something you were told). らしい is vaguer — "apparently", from reputation or a rumour you cannot fully vouch for.

FAQ

Can I use だ with the appearance そう? Yes, and it is normal in casual speech: おいしそうだ, りそうだ. The polite version is おいしそうです. What you cannot do is add だ to the front of the appearance そう the way hearsay does.

Does hearsay そう have a past tense? The tense lives in the clause in front, not on そう: ったそうです ("I heard it rained"). るそうでした is not used — you report what you heard in the present, and the reported event carries its own tense.

How do I name the source of hearsay? 〜によると at the front: 天気予報てんきよほうによると, ニュースによると, 友達ともだちはなしによると. It is optional, but it makes the sentence much more natural in writing.

Is そうに different from ように? Yes. おいしそうにべる means "eat in a way that looks delicious" (real enjoyment, visible on your face). おいしいようにべる is not a natural sentence. ように compares to something: 子供こどものようにべる = "eat like a child."

Can appearance そう be used about myself? For feelings and physical states, constantly: きそう, たおれそう, ねむそう… though ねむそう about yourself is odd, since you know whether you are sleepy. Use it for things that are about to happen to you, not for describing your own inner state you already know.

Is there a そう that means "that's right"? Yes, and it is unrelated to both of these — そうです as an answer means "that's correct," and そうですね means "let me think" or "you're right" depending on tone. Same sound, different word entirely.

I'm Yuuki, a Japanese teacher based in Tokyo. I've taught on italki as a Top 1% teacher and watched over 1,500 anime. In lessons this one hides for months, because a mixed-up そう is never a broken sentence — it is a perfectly polite sentence that quietly says you saw something you were actually only told about.
