Appearance そう in Japanese

In Brief

Add そう to an adjective stem or a verb's ます-stem to describe an impression based on what you can directly observe: おいしそうです means “It looks delicious,” while 雨が降りそうです means “It looks like it will rain.” With an い-adjective, remove the final い; with a な-adjective, remove な. Do not confuse this with hearsay そうです, which attaches to a complete plain form and means “I hear that…”.

Overview

Appearance そう lets you describe how something strikes you from the evidence available now. You may see a beautifully presented cake and say おいしそう, notice dark clouds and say 雨が降りそう, or look at someone's expression and say 元気そう. English often uses “looks,” “seems,” “appears,” or “looks like it is going to.” The Japanese construction focuses on an immediate impression rather than a confirmed fact.

This is a core A2 pattern. Its formation is short, but it changes according to the kind of word before it. A stem is the part left after an ending has been removed. For example, remove い from おいしい to get おいし-, and take the part before ます in 降ります to get 降り-.

English speakers should pay attention to the source of the judgment. English “seems” can cover visual impressions, logical conclusions, and reported information. Japanese commonly distinguishes these meanings. Appearance そう is a natural choice when the situation itself gives you an immediate clue; other patterns such as ようだ and みたい handle broader inference and resemblance.

How It Works

The beginner rule

The attachment rule depends on the word class (the grammatical type of word):

Word type	Base form	Change	Form with そう	Usual meaning
い-adjective	おいしい	Remove final い	おいしそう	looks delicious
い-adjective	難しい	Remove final い	難しそう	looks difficult
な-adjective	元気な	Remove な	元気そう	seems well/energetic
な-adjective	静かな	Remove な	静かそう	seems quiet
Verb	降ります	Remove ます	降りそう	looks likely to rain/fall
Verb	泣きます	Remove ます	泣きそう	looks about to cry

With adjectives, そう describes an apparent quality. You are not stating that the cake is definitely delicious or that the task is definitely difficult; you are describing the impression it gives.

• おいしいです。 — It is delicious. You know or present this as a fact.
• おいしそうです。 — It looks delicious. You are judging from its appearance or another immediate clue.

With verbs, そう usually expresses a prediction based on present signs or an event that appears close to happening:

• 雨が降りそうです。 — It looks like it is going to rain.
• コップが落ちそうです。 — The glass looks like it is about to fall.

Making the ます-stem

The ます-stem is the form immediately before ます in the polite present form. This avoids having to memorise a separate rule for each verb group.

Dictionary form	Polite form	ます-stem	Appearance form
食べる	食べます	食べ	食べそう
行く	行きます	行き	行きそう
降る	降ります	降り	降りそう
する	します	し	しそう
来る	来ます	来（き）	来（き）そう

Notice that 降るそうです is not the appearance form. Because 降る is a complete plain form, 降るそうです normally means “I hear it will rain.”

Using the result in a sentence

An appearance expression with そう behaves much like a な-adjective. It can end a sentence, modify a noun with な, or modify an action with に.

Function	Pattern	Example	Meaning
Sentence predicate	stem + そうです	この料理は辛そうです。	This dish looks spicy.
Before a noun	stem + そうな + noun	面白そうな映画	a movie that looks interesting
Before a verb	stem + そうに + verb	楽しそうに話す	speak as if having fun
Past impression	stem + そうでした	彼は眠そうでした。	He looked sleepy.

A predicate is the part of a sentence that says something about the topic. In この料理は辛そうです, 辛そうです is the predicate.

Two important irregular forms

Two very common words do not follow the simplest remove-い rule:

Base form	Correct appearance form	Not
いい / よい (good)	よさそう (looks good)	× いそう / × いいそう
ない (not; nonexistent)	なさそう (does not seem; seems absent)	× ないそう

The inserted さ also appears when ない is part of a negative adjective or verb form:

• 高くなさそうです。 — It does not look expensive.
• 雨は降らなさそうです。 — It does not look like it will rain.

Two kinds of negative meaning

Japanese can distinguish “it does not look X” from “it looks not-X.” In everyday translation they may overlap, but the focus differs.

Form	Example	Main idea
そうではない / そうじゃない	おいしそうではない。	It is not the case that it looks delicious.
Negative base + そう	おいしくなさそうだ。	It looks as though it is not delicious.
Negative verb + そう	彼は来なさそうだ。	It looks as though he will not come.

For a beginner, おいしくなさそう and 来なさそう are the most useful patterns when the negative impression itself is what you want to express.

Common Mistakes

Keeping the final い of an い-adjective

• Wrong: おいしいそうです。
• Right: おいしそうです。
• Why: Appearance そう attaches to the stem, so remove the final い from おいしい. The wrong form can also be heard as an attempted hearsay construction: “I hear it is delicious” is おいしいそうです, with the full adjective before hearsay そうです.

Adding な between a な-adjective and そう

• Wrong: 元気なそうです。
• Right: 元気そうです。
• Why: Remove な before adding appearance そう. Use な after そう only when the whole expression modifies a noun: 元気そうな人 (“a person who looks well”).

Attaching appearance そう to a dictionary-form verb

• Wrong: 雨が降るそうです。 when you mean “It looks like rain.”
• Right: 雨が降りそうです。
• Why: Appearance そう uses the ます-stem, 降り. 降るそうです means “I hear it will rain,” so this small form difference changes the source of the information.

Forming “looks good” as いいそう

• Wrong: この案はいいそうです。 when judging the idea yourself
• Right: この案はよさそうです。
• Why: Appearance そう uses the irregular form よさそう. いいそうです normally means “I hear it is good.”

Forgetting な or に after そう

• Wrong: おいしそうケーキ / 楽しそう話しています
• Right: おいしそうなケーキ / 楽しそうに話しています
• Why: Use そうな before a noun (a person, place, thing, or idea) and そうに before a verb when describing how an action appears.

Using appearance そう for a known fact

• Awkward: このケーキを食べました。おいしそうです。 when you mean that it tasted good
• Natural: このケーキを食べました。おいしかったです。
• Why: Once you have tasted the cake, おいしかった directly states your experience. おいしそう describes the impression it gives, usually before you confirm the taste.

Usage Notes

Appearance そう is common in both conversation and writing. そうだ is plain style, while そうです is polite. In casual speech you will often hear reactions such as おいしそう！ (“Looks delicious!”) or 楽しそう！ (“Looks fun!”) with no final だ.

The evidence need not be purely visual. A voice can make someone 元気そう (“sound well”), and current circumstances can make a plan うまくいきそう (“look likely to work”). The key is that the speaker is responding to available signs rather than reporting another person's statement. Context decides whether English translates the form as “look,” “sound,” “seem,” or “be likely to.”

Be thoughtful when judging people. Forms such as 疲れそう and 疲れていそう do not say the same thing: 疲れそう means “looks likely to become tired,” whereas 疲れていそう means “seems to be tired.” For a current state produced by an earlier action, Japanese often puts そう after a ている-based stem, as discussed below.

Beyond the Basics

You do not need to master every contrast at A2, but these forms explain many sentences you will meet later.

Appearance そう versus hearsay そう

The two patterns sound alike but attach differently and answer different questions.

Meaning	Attachment	Example	Translation
Appearance	adjective stem / verb ます-stem + そう	雨が降りそうです。	It looks like it will rain.
Hearsay	complete plain form + そう	雨が降るそうです。	I hear it will rain.
Appearance	おいし + そう	おいしそうです。	It looks delicious.
Hearsay	おいしい + そう	おいしいそうです。	I hear it is delicious.

Hearsay そう reports a source. Appearance そう presents the speaker's impression. In speech, the surrounding context and the attachment form make the distinction clear.

そう with ongoing and completed-looking states

Appearance そう can follow the stem of a polite ている form. This allows you to infer a current state rather than predict a future action:

• 彼は疲れていそうです。 — He seems to be tired.
• 田中さんはその答えを知っていそうです。 — Ms Tanaka seems to know the answer.
• この店はもう閉まっていそうです。 — This shop seems to be closed already.

Compare 泣きそう (“about to cry”) with 泣いていそう (“seems to be crying”). The first predicts the start of an action; the second infers that the action is in progress.

そうにない and そうもない

A verb stem followed by そうにない expresses that something appears unlikely to happen. そうもない can strengthen the sense of “not at all likely.” These are useful alternatives to なさそう:

• 雨は降りそうにありません。 — It does not look likely to rain.
• 今日中には終わりそうもない。 — It does not look at all likely to be finished today.

The polite そうにありません is common in careful speech and writing. At first, it is enough to recognise it as the negative of “looks likely to happen.”

Contrast with ようだ and みたい

ようだ and conversational みたい have a wider range. They can express a conclusion drawn from evidence, resemblance, or comparison, and they attach to complete clauses and nouns in ways appearance そう does not.

• 雨が降りそうです。 — Dark clouds make rain look imminent.
• 道がぬれています。雨が降ったようです。 — The road is wet; it appears that it rained.
• この雲は動物みたいです。 — This cloud looks like an animal.

A useful first distinction is: choose appearance そう for the quality or event that the present scene directly suggests; expect ようだ / みたい when reasoning from evidence or saying that one thing resembles another.

Practice Tips

1. Use a three-column drill. Write the base form, the stem, and the result: 難しい → 難し → 難しそう, 元気な → 元気 → 元気そう, 降ります → 降り → 降りそう. Include いい → よさそう and ない → なさそう every time until they feel automatic.
2. Describe what is around you. Look at a menu, the weather, or people's expressions and make five immediate observations: おいしそう, 雨が降りそう, 忙しそう. Then add a noun or action with な or に: おいしそうな料理, 楽しそうに笑う.
3. Practise the information-source contrast aloud. Pair sentences such as 雪が降りそうです (“It looks likely to snow”) and 雪が降るそうです (“I hear it will snow”). Hearing the stem difference helps prevent confusion between appearance and hearsay.
