<blockquote class="pullquote">
  およそ is not just ”about”—in negative sentences it means ”utterly” or ”not at all”. That double identity makes it N1‑level.
</blockquote>

**およそ** means **about; roughly; generally; approximately; completely​ ~**. It is a **JLPT N1** Japanese grammar pattern used to approximate a quantity, degree, or state—and, conversely, to completely negate something.

This grammar point appears often in formal writing, news, and JLPT N1 reading passages. If you need a single word that can both soften a number and harden a denial, **およそ** is a pattern you’ll want to master.

## What does およそ mean?

Use **およそ** when you want to express an approximate quantity, a general tendency, or a total negation.

Natural translations include:
- about; roughly; generally; approximately; completely (not)

The key is context: with numbers it softens precision; with negative predicates it erases doubt entirely. Always check the sentence polarity before picking an English equivalent.

## How to form およそ

**およそ** is an adverb that attaches to numbers, counters, nouns, or negative predicates.

<div class="formation">
  <span class="ftoken t-core">およそ</span>
  <span class="fplus">+</span>
  <span class="ftoken t-stem">quantity / time / people</span>
</div>
<div class="formation">
  <span class="ftoken t-core">およそ</span>
  <span class="fplus">+</span>
  <span class="ftoken t-stem">Verb‑<ruby>ない<rt>ない</rt></ruby> / <ruby>形容詞<rt>けいようし</rt></ruby>‑<ruby>否定<rp>(</rp><rt>ひてい</rt><rp>)</rp></ruby></span>
</div>
<div class="formation">
  <span class="ftoken t-core">およそ</span>
  <span class="fplus">+</span>
  <span class="ftoken t-aux">の</span>
  <span class="fplus">+</span>
  <span class="ftoken t-stem">Noun (as modifier)</span>
</div>

Examples of the patterns:
- およそ5<ruby>分<rp>(</rp><rt>ぶん</rt><rp>)</rp></ruby>
- およそ30<ruby>人<rp>(</rp><rt>ひと</rt><rp>)</rp></ruby>
- およそ<ruby>理解<rp>(</rp><rt>りかい</rt><rp>)</rp></ruby>できなかった
- およその<ruby>見当<rp>(</rp><rt>けんとう</rt><rp>)</rp></ruby>

When used as an adverb directly before a negative form, the に particle is not needed. The wrong answer choices on the JLPT often add unnecessary particles.

## When is およそ used?

Use **およそ** in situations like:
- giving an approximate number or time in a formal report
- describing a general trend that isn’t exact
- strongly denying something in a written argument
- setting an approximate scope in a discussion

Tone and register:
- formal, slightly literary; common in news, business writing, and academic prose
- not typical in casual conversations; there it feels stiff

In spoken Japanese, you would more often hear <ruby>大体<rt>だいたい</rt></ruby> or <ruby>約<rt>やく</rt></ruby> for ”about”. Reserve およそ for situations that demand a polished, weighty tone.

    <div class="example-en">It looks like the meeting has more or less ended.</div>
    <div class="example-foot"><span class="example-tag">general state</span></div>
  </div>
</div>

After reading each sentence, ask what job およそ is doing: softening a number, painting a general picture, or slamming the door on a possibility. The nuance sticks better when you identify the function first.

## Nuance of およそ

The core nuance is duality: **approximation vs. total negation**.  
When the sentence is positive, およそ signals ”not exactly, but near enough”. When the sentence is negative, it flips into ”not at all / not in any way / scarcely”.

This matters because learners often learn およそ only as ”about” and then misread a negative sentence. A pattern that looks simple can dramatically change meaning based on polarity.

Another subtle point: およそ with a noun plus の（およその<ruby>計画<rp>(</rp><rt>けいかく</rt><rp>)</rp></ruby> etc.）implies ”a rough outline” rather than a precise estimate. That outline can be ”almost nothing” in a negative context.

<div class="note-callout">
  <div class="note-icon">⚠️</div>
  <div class="note-body">Don’t assume およそ is always ”approximately”. When it meets a negative verb, it intensifies the negation. Treat it as two separate entries in your mental dictionary.</div>
</div>

## およそ vs <ruby>約<rp>(</rp><rt>やく</rt><rp>)</rp></ruby>

Both **およそ** and **<ruby>約<rp>(</rp><rt>やく</rt><rp>)</rp></ruby>** can be translated as ”about”, but they carry different registers and ranges.

<div class="compare">
  <div class="cmp">
    <div class="cmp-head">およそ</div>
    <div class="cmp-sub">roughly, generally, utterly not</div>
    <div class="cmp-when">Used before numbers, nouns, and negative predicates. Carries a formal, literary tone. Emphasizes the ”approximately” idea or a broad outline, not precise rounding.</div>
    <div class="cmp-eg">およそ100<ruby>人<rp>(</rp><rt>ひと</rt><rp>)</rp></ruby>の<ruby>参加者<rp>(</rp><rt>さんかしゃ</rt><rp>)</rp></ruby></div>
    <div class="cmp-eg-en">roughly 100 participants</div>
    <div class="cmp-eg">お<ruby>金のこ<rp>(</rp><rt>かなのこ</rt><rp>)</rp></ruby>とはおよそ<ruby>考え<rp>(</rp><rt>かんがえ</rt><rp>)</rp></ruby>ていない。</div>
    <div class="cmp-eg-en">I’m not thinking about money at all.</div>
  </div>
  <div class="vs">vs</div>
  <div class="cmp">
    <div class="cmp-head"><ruby>約<rt>やく</rt></ruby></div>
    <div class="cmp-sub">approximately (numeric)</div>
    <div class="cmp-when">Strictly for numeric quantities. Very common in data, journalism, and presentations. Rarely appears in negative sentences, and cannot mean ”utterly”.</div>
    <div class="cmp-eg"><ruby>約<rp>(</rp><rt>やく</rt><rp>)</rp></ruby>100<ruby>人<rp>(</rp><rt>ひと</rt><rp>)</rp></ruby>の<ruby>参加者<rp>(</rp><rt>さんかしゃ</rt><rp>)</rp></ruby></div>
    <div class="cmp-eg-en">approximately 100 participants</div>
  </div>
</div>

If both translations seem possible, check whether the sentence is purely numeric and whether the overall tone is written and formal. <ruby>約<rp>(</rp><rt>やく</rt><rp>)</rp></ruby> fits best in a report; およそ broadens the scope to general tendencies and strong denials.

    </div>
    <div class="note">In casual conversation, およそ sounds overly stiff. だいたい or ほぼ are more natural.</div>
  </div>
  <div class="mistake">
    <div class="mline bad">
      <span class="mark bad">❌</span>
      <span class="mline-body"><ruby>試験<rt>しけん</rt></ruby>はおよそ<ruby>全滅<rt>ぜんめつ</rt></ruby>だ。</span>

      <span class="mline-body"><ruby>試験<rp>(</rp><rt>しけん</rt><rp>)</rp></ruby>はほぼ<ruby>全滅<rp>(</rp><rt>ぜんめつ</rt><rp>)</rp></ruby>だ。</span>
    </div>
    <div class="note">When you want ”almost entirely / nearly”, ほぼ is safer. およそ in a positive sentence leans toward ”roughly”, not ”virtually”.</div>
  </div>
</div>

A helpful habit: after writing a sentence with およそ, replace it with <ruby>約<rp>(</rp><rt>やく</rt><rp>)</rp></ruby> or だいたい. If the nuance doesn’t shift, you probably used it correctly. But when the replacement breaks the negative force or the formal feel, keep およそ.

## Is およそ on the JLPT?

<div class="jlpt-card">
  <div class="jlpt-shield">N1</div>
  <div class="jlpt-info">
    およそ is firmly a <strong>JLPT N1</strong> grammar item. It appears in reading comprehension sections and, less frequently, in grammar/vocabulary questions where they test whether you know its negative-intensifying use.
  </div>
  <div class="jlpt-checks">
    <div class="check"><span>✔</span> Recognize both approximate and negative usages</div>
    <div class="check"><span>✔</span> Differentiate from <ruby>約<rp>(</rp><rt>やく</rt><rp>)</rp></ruby>, だいたい, ほぼ</div>
    <div class="check"><span>✔</span> Understand its formal register</div>
  </div>
</div>

N1 passages often embed a single およそ inside a long sentence to test if you catch the shift from ”about” to ”not at all”. Read the sentence aloud and listen for the polarity.

Keep your early sentences straightforward, then add more situational flavor (news report, academic summary, formal apology) so the formal tone becomes natural.

  <div class="path-step">
    <div class="step-num">3</div>
    <div class="step-body">
      <strong>Read formal texts.</strong> Scan a Japanese news article or an academic abstract. Circle every およそ and decide whether it means ”about” or ”not at all”. This trains your brain to use context instantly.

</div>

The goal isn’t just memorizing ”およそ = about”. It’s knowing exactly when its formal, literary bite is the right tool.

## Related grammar to review next

- [さ](/blog/n1-sa/) — the sentence‑ending particle さ can mark a quality or degree; in some contexts it overlaps with およそ when approximating a general feeling, and both live in the N1 formal‑spoken toolkit.
- [<ruby>折<rt>おり</rt></ruby>に](/blog/n1-ori-ni/) — <ruby>折<rp>(</rp><rt>おり</rt><rp>)</rp></ruby>に means ”on the occasion of”, a formal phrase for setting context. It shares the polished register of およそ and appears in similar written passages.
- [さも](/blog/n1-samo/) — さも intensifies a statement (”truly, indeed”), much like およそ intensifies a negation. Learning them together helps you sense emphatic adverbs in formal Japanese.
- [<ruby>思<rt>おも</rt></ruby>いをする](/blog/n1-omoi-o-suru/) — <ruby>思い<rp>(</rp><rt>おもい</rt><rp>)</rp></ruby>をする expresses ”to feel / to have an experience”. Combined with およそ, it can convey an approximate feeling (およその<ruby>思い<rp>(</rp><rt>おもい</rt><rp>)</rp></ruby>), a construction that deepens your control over abstract descriptions.
