〜という: the grammar for naming, quoting, and defining things

〜という is quotation particle と plus 言いう ("to say"), and it means "called ~" or "that ~". It attaches a name, a quote or a whole clause to a noun: 田中たなかという人ひと is "a person called Tanaka," 高たかいということ is "the fact that it is expensive." Once you see the と, every use of it stops looking like a separate grammar point.

という is one of those pieces of Japanese that appears everywhere, gets taught four separate times under four separate names, and turns out to be one thing doing one job. Getting the underlying idea saves you memorizing the variants.

The basics

What is という literally doing?

と marks quoted content. 言いう means "to say." So という is "saying that," and everything in front of it is what gets said.

田中たなかという人ひとから電話でんわがありました。 — There was a call from a person called Tanaka. (polite — 田中たなか is the content being said) 「もったいない」という言葉ことばがあります。 — There is a word called もったいない. (polite, introducing a term)

Put simply: X という Y means "the Y that is called X." The と is the seam between the name and the thing.

Naming: introducing something unfamiliar

The most common use is introducing something the listener does not know yet.

「たこ焼やき」という食べ物たべものを食たべました。 — I ate a food called takoyaki. (polite, introducing a new noun) 東京とうきょうという町まちは大おおきすぎます。 — Tokyo, this city, is too big. (polite — a slight distancing, "this thing called Tokyo")

Notice the second one. Using という with something the listener obviously knows adds a flavour: it frames the thing as a concept rather than a familiar object. That is a real nuance, not an error, and it is common in writing and in speeches.

Defining: 〜ということ

Attach ということ to a clause and you turn the whole clause into a noun meaning "the fact that."

彼かれが来こないということは、忙いそがしいんでしょう。 — The fact that he isn't coming means he must be busy. (polite, reasoning aloud)

This is the move that lets Japanese talk about sentences. こと alone nominalizes a clause; ということ nominalizes it as a proposition — something reportable, arguable, a piece of information rather than an activity. For the plain nominalizer, see こと vs の.

Beyond the basics

っていう and って: the same grammar, spoken

In speech という contracts, and it contracts hard.

田中たなかっていう人ひと、知しってる? — Do you know a guy called Tanaka? (casual) 田中たなかって人ひと、知しってる? — Same, shortened further. (casual) もう終おわったって。 — They said it's already over. (casual — って alone carries the whole "they say")

That last one is the important one. Sentence-final って is a reported-speech marker meaning "apparently" or "they said," and it is enormously common. It is という with everything except the と worn away.

〜ということだ: "apparently" / "which means"

Attached to the end of a sentence, ということだ reports or concludes.

明日あしたは休やすみだということです。 — Apparently tomorrow is a holiday. (polite, reporting) つまり、行いかないということですね。 — So in other words, you're not going. (polite, confirming a conclusion)

The second use — confirming that you have understood — is one of the most useful sentences in any real conversation. つまり〜ということですね lets you check your understanding without asking the person to repeat themselves, which is far less disruptive than 「もう一度いちどお願ねがいします」.

という vs the quotation と: what changes

Bare と quotes speech. という attaches that quote to a noun.

「行いきます」と言いいました。 — He said "I'll go." (polite — quoting speech) 行いくということでした。 — It was to the effect that he'd go. (polite — reporting the content)

The second is vaguer on purpose. Japanese often prefers reporting the gist rather than the words, and ということ is the tool for that. See 〜と思おもいます for the same と doing the same job with thought instead of speech.

〜というか: "or rather"

Attach か and you get a self-correction marker, extremely common in speech.

嫌きらいというか、興味きょうみがないんです。 — It's not that I dislike it — more that I'm not interested. (polite-casual, softening)

というか lets you walk back a word you just used without retracting the whole sentence. It is a politeness tool as much as a grammar point: it softens a blunt word by replacing it mid-sentence.

〜といっても: "although I say ~"

日本語にほんごができるといっても、まだ初級しょきゅうです。 — I say I can speak Japanese, but I'm still a beginner. (polite, hedging a claim)

This one exists to pre-empt an overestimate. It is the grammar of modesty, and you will hear it constantly from Japanese speakers describing their own abilities.

Common mistakes

  • Using という with a noun the listener already knows, by accident. 私わたしの母ははという人ひと sounds odd — it distances your own mother into a concept. Use it for things that need introducing.
  • Forgetting the と in writing. 田中たなかいう人ひと is dialect at best; standard Japanese needs 田中たなかという人ひと.
  • Treating ということ and こと as interchangeable. 泳およぐこと is "swimming" as an activity. 泳およぐということ is "the fact/idea that one swims."
  • Reading 言いう here as a real verb. In という it is grammaticalized — nobody is literally saying anything in 東京とうきょうという町まち.
  • Overusing ということです in writing. It softens and distances. Two in a paragraph reads as evasive.
  • Missing sentence-final って. Learners often hear it as a particle they do not know. It is という, and it means "apparently."

The という family

Form Meaning Example
X という Y A Y called X 田中たなかという人ひと
〜ということ The fact that ~ 来こないということ
〜ということだ Apparently ~ / which means ~ 休やすみだということです
〜というか Or rather ~ 嫌きらいというか
〜といっても Although I say ~ できるといっても
〜って (casual) Called ~ / apparently ~ 田中たなかって人ひと / 終おわったって

Practice

Questions 3 and 4 are the pair: the same clause with こと and with ということ, and they are not the same sentence.

1. Say "there was a call from a person called Tanaka," politely.

Show answer

田中たなかという人ひとから電話でんわがありました。 — X という Y: the name, then the thing it names.

2. Introduce a food called takoyaki.

Show answer

「たこ焼やき」という食べ物たべものです。 — という is for things the listener may not know yet.

3. Turn 泳およぐ into "swimming" as an activity.

Show answer

泳およぐこと — Plain nominalizer. This is the activity itself.

4. Turn 泳およぐ into "the fact that one swims."

Show answer

泳およぐということ — ということ makes it a proposition, something reportable rather than something done.

5. Confirm politely that you have understood: "so, you're not going."

Show answer

つまり、行いかないということですね。 — The single most useful comprehension check in conversation.

6. Report casually that something is apparently over.

Show answer

もう終おわったって。 — Sentence-final って is という worn down. It means "they said" or "apparently."

7. Soften "I dislike it" into "more that I'm not interested."

Show answer

嫌きらいというか、興味きょうみがないんです。 — というか walks back a blunt word mid-sentence.

8. Hedge: "I say I can speak Japanese, but I'm still a beginner."

Show answer

日本語にほんごができるといっても、まだ初級しょきゅうです。 — といっても pre-empts an overestimate. Very common about one's own abilities.

9. Fix this: 田中たなかいう人ひとから電話でんわがありました。

Show answer

田中たなかという人ひとから電話でんわがありました。 — Standard Japanese needs the と. Without it you are writing dialect.

10. Why does 私わたしの母ははという人ひと sound strange?

Show answer

という is for introducing something unfamiliar. — Applying it to your own mother turns her into a concept, which is a very odd thing to do to a family member.

FAQ

Is という the same as the quotation と? It contains it. と marks the quoted content; 言いう makes it into something attachable to a noun. Everything という does follows from that.

Why do I keep hearing って at the end of sentences? That is という compressed. It reports what someone said: 雨あめだって means "apparently it's raining." Recognizing it will unlock a large amount of casual speech.

When is という required rather than optional? When introducing an unfamiliar name: 田中たなかという人ひと is necessary if the listener does not know Tanaka. When the noun is already known, dropping it is usually better.

What is the difference between ということです and そうです? そうです ("I heard") points at a source you are relaying. ということです is closer to "which amounts to saying," and is also used to draw a conclusion. See そうです for the two meanings that word carries.

Is というか rude? The opposite — it is a softener. It lets you correct your own word choice mid-sentence rather than leaving a blunt word standing.

Does という ever take a past form? The 言いう part can conjugate: といった, といっていた. ~といっても and ~といえば are fixed forms built from those, and each has its own meaning, so treat them as separate items rather than tenses.

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. という is the point where students stop learning grammar items and start seeing the machinery — and sentence-final って is the moment casual anime dialogue suddenly becomes parseable.
