〜という (to iu)
Have you ever been reading a Japanese manga or listening to a podcast and felt like you were following along perfectly, only to be stopped in your tracks by the phrase 〜という (to iu)? It seems to pop up everywhere—between nouns, at the end of sentences, and even in the middle of complex descriptions. You might have learned in your first few weeks of Japanese study that “iu” (言う) means “to say,” but as you progress toward the JLPT N4 and N3 levels, you quickly realize that 〜という is much more than just a verb for speaking.
In fact, 〜という is one of the most versatile “glue” expressions in the Japanese language. It acts as a bridge that connects specific names to general categories, summarizes complex ideas, and adds a layer of explanation that makes your Japanese sound more natural and sophisticated. If you’ve ever struggled to explain a specific dish from your home country or tried to relay a message someone else told you, this grammar point is your best friend.
In this guide, we are going to break down the mystery of 〜という. We’ll look at its basic rules, dive into some real-world examples you can use tonight, and highlight the common traps that trip up even the most dedicated students. Let’s get started!
Before diving into the grammar detail, here is the JLPT N4 complete guide:
The Ultimate JLPT N4 Complete Guide: Your Gateway to Working and Living in Japan
The Basic Mechanics of To Iu
At its core, 〜という is used to define, name, or describe something. Think of it as a way to say “called,” “named,” or “the thing that is…” in English. While it technically comes from the verb “to say,” in this grammatical context, it’s functioning more like a particle or a linking phrase.
The Naming Pattern
The most common way you will see this is in the pattern: [Noun A] という [Noun B]. In this structure, Noun A is a specific name or title, and Noun B is the general category it belongs to. It translates to “The [Noun B] called [Noun A].”
For example, if you want to talk about a friend named Tanaka whom the listener doesn’t know, you would say 田中さんという人 (Tanaka-san to iu hito)—”The person called Tanaka-san.” This provides context to the listener, letting them know that “Tanaka” is the name of a “person.”
The Descriptive Pattern
Another way we use this is to explain the content of a piece of information, such as a rumor, a news report, or a feeling. The structure is [Sentence/Clause] という [Noun]. This is often translated as “The [Noun] that [Sentence].” For instance, “The news that the price of bread is rising” would use this structure to link the specific news content to the word “news” (ニュース).
Practical Examples for Daily Life
To really get a feel for how 〜という flows in a conversation, let’s look at three scenarios you are likely to encounter while living or traveling in Japan.
Introducing Something New
Imagine you are at a party and you’ve brought a traditional snack from your home country. Your Japanese friends have never seen it before. You wouldn’t just say the name; you would use 〜という to explain what it is.
Example:
これは「ラミントン」というオーストラリアの菓子です。
(Kore wa ‘Raminguton’ to iu Oosutoraria no kashi desu.)
Translation: This is an Australian sweet called a “Lamington.”
In this case, “Lamington” is the specific name, and “Australian sweet” is the category. Without 〜という, the sentence might sound a bit blunt or confusing to someone who has never heard the word “Lamington” before.
Relaying a Message or Definition
Sometimes you need to talk about a concept or a specific rule. Maybe you’re at work and you’re explaining a company policy, or you’re at school discussing a specific term.
Example:
最近、「ワーケーション」という言葉をよく聞きます。
(Saikin, ‘waakeshon’ to iu kotoba wo yoku kikimasu.)
Translation: Lately, I often hear the word called “workation” (work + vacation).
By using という here, you are identifying that “workation” is a “word” (言葉 – kotoba). This is a very common way to introduce new vocabulary or slang into a conversation.
Summarizing an Idea or Fact
This is where 〜という becomes essential for JLPT N3 level and above. You can use it to wrap up a whole sentence and turn it into a single noun phrase. This is often used with words like こと (koto – thing/fact) or ニュース (nyuusu – news).
Example:
彼が会社を辞めるという噂は本当ですか？
(Kare ga kaisha wo yameru to iu uwasa wa hontou desu ka?)
Translation: Is the rumor that he is quitting the company true?
Here, the entire thought “he is quitting the company” is being linked to the noun “rumor” (噂 – uwasa). This allows you to talk about the rumor itself as the subject of your question.
Common Pitfalls and How to Avoid Them
Learning 〜という seems simple enough at first, but there are a few areas where students often trip up. Let’s look at how to avoid those common mistakes.
Don’t Forget the Particle “To”
In casual speech, Japanese people often shorten things, but when you are writing for the JLPT or speaking in a semi-formal setting, you must include the と (to). Some learners accidentally say “iu Noun” instead of “to iu Noun.” Remember that と acts as the quotation mark here. It signals that the word before it is the name or the content being described.
Confusing “To Iu” with “To Iimasu”
While という comes from 言います (iimasu), they are used differently in a sentence. When you are using it as a grammar bridge (the way we discussed above), you almost always use the dictionary form という, even if the rest of the sentence is polite (ending in ~masu or ~desu).
Correct: 田中さんという人を知っていますか？ (Do you know the person called Tanaka-san?)
Incorrect: 田中さんと言います人を知っていますか？ (This sounds very unnatural.)
You only use と言います (to iimasu) when you are actually reporting speech at the end of a sentence, such as “He said…” or “My name is…”
Overusing it for Famous Things
If something is incredibly famous and everyone knows it, you don’t always need to use という. For example, if you say “The mountain called Mt. Fuji,” it sounds a bit strange because everyone knows what Mt. Fuji is. You would usually just say “Mt. Fuji.” Use という when you think the listener might need the category to understand the specific name you’re using.
The Casual Cousin: Using Tte
As a bonus for your daily life in Japan, it’s important to know that in casual, spoken Japanese, という almost always transforms into って (tte).
If you’re hanging out with friends, you’ll hear:
「田中さんって人」 (Tanaka-san tte hito)
instead of
「田中さんという人」 (Tanaka-san to iu hito).
While って is great for conversation, stick to という for your JLPT exams and formal writing. Understanding that they are the same thing will help you realize just how often this grammar point is used in real life!
Summary
The phrase 〜という is a powerful tool in your Japanese toolkit. It allows you to define new words, introduce people, and summarize complex ideas into simple nouns. By mastering this “bridge,” you move away from simple “Subject-Verb-Object” sentences and start building the kind of nuanced, descriptive Japanese that native speakers use every day.
Remember these three key takeaways:
- Structure: [Specific Name/Content] + という + [General Category].
- Purpose: To define, name, or explain what something is.
- Flexibility: Use it for people, places, things, rumors, and even entire sentences.
Next time you’re out at a restaurant or talking to a language partner, try using 〜という to explain something from your own culture. It’s the perfect way to practice and will make your Japanese sound much more fluent. Keep practicing, and good luck with your JLPT studies!
