〜について vs 〜として: "about" and "as", and why swapping them changes the sentence

〜について means "about, concerning" — it marks what you are talking about. 〜として means "as, in the capacity of" — it marks the role someone is filling. アイドルについて話はなす is "to talk about idols"; アイドルとして話はなす is "to speak as an idol." Same noun, entirely different sentence.

These two are taught together because learners reach for the wrong one under pressure, and the error is not a small one — it changes who is doing what.

The basics

〜について: the topic

Attach について directly to a noun. No particle in between.

日本にほんの文化ぶんかについて話はなしました。 — I talked about Japanese culture. (polite) その問題もんだいについて考かんがえています。 — I'm thinking about that problem. (polite)

について is built from につく ("to attach to") and means "attached to the matter of." It is the standard way to name a topic when the verb needs one: 話はなす, 書かく, 考かんがえる, 質問しつもんする, 説明せつめいする.

〜として: the capacity

Also attaches directly to a noun, and means "in the role of."

教師きょうしとして働はたらいています。 — I work as a teacher. (polite) 友達ともだちとして言いいますが… — I'm saying this as a friend, but… (polite — a warning that honesty is coming)

That second one is worth memorizing. 〜として言いいますが is the standard preamble for saying something uncomfortable, and the として tells the listener which hat you are wearing.

Side by side

アイドルについて話はなしました。 — I talked about idols. (polite — idols were the topic) アイドルとして話はなしました。 — I spoke as an idol. (polite — I was the idol)

The difference is not subtle in meaning, only in form. One syllable apart, and the second sentence claims you are a pop star.

Beyond the basics

についての: modifying a noun

To attach an について phrase to a noun, insert の.

日本にほんについての本ほんを読よみました。 — I read a book about Japan. (polite)

日本にほんについて本ほん is missing a piece. The の is required, and this is the same pattern as 〜からの and 〜までの — any adverbial phrase attaching to a noun needs の.

について vs に対たいして: topic vs target

に対たいして also translates as "toward" or "with regard to," and the two get confused.

  • について — the topic being discussed
  • に対たいして — the target an attitude or action is aimed at

彼かれについて話はなしました。 — I talked about him. (polite — he was the subject matter) 彼かれに対たいして怒いかっています。 — I'm angry at him. (polite — he is the target of the anger)

The test: can you replace it with "on the subject of"? If yes, について. If the sentence is about an attitude or force directed at someone, に対たいして.

に対たいして is also the word for contrast in writing: AAに対たいしてBBは… ("whereas A, B…"), which is a different use worth recognizing separately.

What does にとって mean, and how is it different from について?

にとって marks a viewpoint: "for X", "from X's perspective", "as far as X is concerned". Where について tells you what is being discussed and に対たいして tells you what an action is aimed at, にとって tells you whose scale a judgement is being measured on.

私わたしにとって、これは大おおきな決断けつだんです。 — For me, this is a big decision. (polite — measured against my own scale) 子こどもにとって難むずかしい本ほんです。 — It's a difficult book for a child. (polite — difficult from a child's position)

The clearest way to separate it from について is that にとって almost always sits next to an evaluation — 大事だいじ, 難むずかしい, 必要ひつよう, いい — because a viewpoint only matters when something is being judged. 私わたしについて大おおきな決断けつだんです is not a sentence; 私わたしにとって大おおきな決断けつだんです is.

Two things to watch. First, にとって takes a person or a group, not usually a thing: 会社かいしゃにとって, 日本人にほんじんにとって, 私わたしにとって. Second, it is not a substitute for は — 私わたしは大変たいへんです says I am having a hard time, while 私わたしにとって大変たいへんです says the thing is hard by my standards, which leaves open that someone else might find it easy.

The polite written form is にとりまして, which you will meet in business email and speeches: 弊社へいしゃにとりまして, "for our company".

に関かんして: the formal について

に関かんして (にかんして) means the same as について and belongs to business and written Japanese.

その件けんに関かんしては、後あとほどご連絡れんらくします。 — Regarding that matter, I'll be in touch later. (formal, business)

その件けんに関かんして is boilerplate in Japanese business email. You do not need to produce it as a learner, but it appears constantly, and recognizing it as "about that" saves you a dictionary look-up every time.

として in its other uses

として also appears in patterns that have drifted from the plain "as."

結果けっかとして、うまくいきました。 — As a result, it went well. (polite) 一人ひとりとして反対はんたいしませんでした。 — Not one person objected. (polite — 一人ひとりとして + negative means "not a single")

That second one is a fixed pattern: 一人ひとりとして, 一ひとつとして and 一度いちどとして all take a negative and mean "not a single one." It reads as emphatic and slightly formal.

とすると and としたら: the conditional cousins

Not the same grammar, but close enough in shape to confuse.

行いくとしたら、いつがいいですか。 — If you were to go, when would be good? (polite — hypothetical)

としたら supposes a hypothetical, and it is a conditional rather than a role marker. The として inside it is doing the "treating it as" job, which is why it looks familiar.

Common mistakes

  • Using として when you mean について. アイドルとして話はなす claims you are an idol. The topic version is について.
  • Adding a particle before について. 日本にほんについてを話はなしました is wrong. について already does the particle's job.
  • Dropping the の in についての. 日本にほんについて本ほん is incomplete. It is 日本にほんについての本ほん.
  • Using について for the target of an emotion. 彼かれについて怒いかっています is odd. Anger has a target: 彼かれに対たいして.
  • Using に関かんして in casual speech. It is correct but reads as a business email out loud. Say について.
  • Translating として as "like". として is a role, not a comparison. For "like," you want みたい or のように — see みたい, らしい, ようだ.

について, として and their neighbours

Japanese Meaning Example
〜について About, concerning 文化ぶんかについて話はなす
〜についての About (before a noun) 文化ぶんかについての本ほん
〜に関かんして About (formal, written) その件けんに関かんして
〜として As, in the capacity of 教師きょうしとして働はたらく
〜に対たいして Toward, aimed at 彼かれに対たいして怒いかる
〜に対たいして Whereas (contrast, written) AAに対たいしてBBは
〜としたら If we suppose 行いくとしたら

Practice

Questions 1 and 2 are the pair: one syllable apart, and the second one makes you a pop star.

1. Say "I talked about idols," politely.

Show answer

アイドルについて話はなしました。 — について marks the topic.

2. Say "I spoke as an idol," politely.

Show answer

アイドルとして話はなしました。 — として marks the capacity you were acting in. Very different claim.

3. Say "I work as a teacher," politely.

Show answer

教師きょうしとして働はたらいています。 — として attaches straight to the noun, no particle.

4. Say "I read a book about Japan," politely.

Show answer

日本にほんについての本ほんを読よみました。 — The の is required to attach the phrase to 本ほん.

5. Say "I'm angry at him," politely.

Show answer

彼かれに対たいして怒いかっています。 — Anger has a target, so に対たいして rather than について.

6. Say "I talked about him," politely.

Show answer

彼かれについて話はなしました。 — Here he is the subject matter, so について.

7. Preface something uncomfortable: "I'm saying this as a friend, but…"

Show answer

友達ともだちとして言いいますが… — として tells the listener which role you are speaking from. Worth memorizing whole.

8. Write the business version of "regarding that matter."

Show answer

その件けんに関かんして — Boilerplate in Japanese business email. Recognize it rather than produce it.

9. Fix this: 日本にほんについてを話はなしました。

Show answer

日本にほんについて話はなしました。 — について already does the particle's job. No を.

10. Fix this: 日本にほんについて本ほんを読よみました。

Show answer

日本にほんについての本ほんを読よみました。 — Attaching the phrase to a noun requires の.

FAQ

Is について N3 or earlier? It is normally introduced around N3, but it appears in beginner textbooks as a set phrase because it is unavoidable once you want to say what you talked about. Learning it early costs nothing.

What is the difference between について and のこと? のこと is softer and more conversational: 彼かのことを話はなしました ("I talked about him") sounds warmer and less formal than 彼かれについて話はなしました. In casual speech のこと is more common.

Can について attach to a verb? Not directly. Nominalize first: 行いくことについて ("about going"). See こと vs の for which nominalizer to use.

Is として the same as the quotative と? Historically related, but treat them as separate. として is a fixed unit meaning "as." The bare quotative と marks speech and thought.

When would I actually use に対たいして? Whenever an emotion, action or policy is directed at someone or something: 怒いかる, 失礼しつれいだ, 厳きびしい, 優やさしい. Also in written contrast: これに対たいして ("in contrast to this").

Does 〜として ever mean "even one"? In the fixed pattern 一人ひとりとして, 一ひとつとして, 一度いちどとして plus a negative: 一度いちどとして遅おくれたことがない ("has never once been late"). It is emphatic and slightly formal.

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. The について/として swap is the kind of error that is funnier than it is damaging, and it makes the point neatly: として is a claim about who you are, not about what you are discussing.
