💡What is the difference between「は」and「が」?└🇯🇵 Japanese Grammar Tips 「は」vs「が」
If you are learning Japanese, you have probably wondered what’s the difference between 「は」and 「が」? 🤔
You may have learned that 「は」 is a topic marker and 「が」 is a subject marker.
This is a useful starting point, but it does not explain every situation.
In fact, both particles can sometimes appear in very similar sentences, while the meaning or the information the speaker wants to highlight changes.
Instead of trying to find one English translation for each particle, let’s look at five common situations that can help you understand how 「は」 and 「が」 are actually used.
①New information⇨「が」Known topic⇨「は」
💡You can think of it this way
「が」⇨ introduces something new
「は」⇨talks about something already known
Imagine that someone enters the room and you say
👩女(おんな)の人(ひと)が来(き)ました。(A woman came.)
At this point, the woman has not appeared in the conversation before, so she is new information.
In this kind of situation, 「が」 is often used when a person or thing is introduced for the first time.
A little later, you find out who she is and say
👩🏫その女(おんな)の人(ひと)はたけ先生(せんせい)でした。(The woman was Take Sensei.)
Now both the speaker and listener already know which woman they are talking about. Since she has already been introduced, she can become the topic of the conversation, which makes 「は」 natural in the second sentence.
So, as a general guideline, you can think of 「が」 as introducing something new, while 「は」 is often used when talking about someone or something that has already been established in the conversation.
②“Who?” or “What?” ⇨「が」
When you are asking who or what did something, 「が」 is normally used with the question word.
だれが来(き)ましたか。(Who came?)
🙅♂️We would not normally say「だれは来(き)ましたか。」
The answer also normally uses 「が」.
たけ先生(せんせい)が来(き)ました。(Take Sensei came.)
In this conversation, the important information is not the action of coming.
What we want to know is who came, so 「が」 is used to identify the person.
This is a useful pattern to remember because the question and answer often match.
If the question is 「だれが」, the person you identify in the answer will also commonly be followed by「が」
③Something you suddenly see, hear or notice⇨「が」
Imagine you look outside.
🗻あ、富士山(ふじさん)が見(み)える！ (Oh, I can see Mt. Fuji!)
Or you notice your dessert.
🍦あっ、アイスクリームが溶(と)けてる！(Oh, the ice cream is melting!)
In all of these examples, the speaker is reacting to something that has just become noticeable in that moment.
Rather than choosing an established topic and explaining something about it, the speaker is simply describing what they have just seen or heard, so 「が」 often sounds natural in these situations.
④「が」 can mean “this person / this thing”
Another important use of 「が」 appears when you want to identify one particular person from several possibilities.
Compare these two sentences.
1.「は」: たけ先生(せんせい)は日本語(にほんご)の先生(せんせい)です。
2.「が」: たけ先生(せんせい)が日本語(にほんご)の先生(せんせい)です。
(Take Sensei is the Japanese teacher.)
The first sentence simply gives us information about Take Sensei.
We are already talking about her, and the sentence tells us that she is a Japanese teacher.
The second sentence has a different feeling.
It can be used when there are several people and you want to make clear which person is the Japanese teacher.
In this case, 「が」 gives the sentence a feeling similar to “Take Sensei is the one.”
For example, imagine that you see several teachers and ask
A：だれが日本語(にほんご)の先生(せんせい)ですか。(Who is the Japanese teacher?)
B：たけ先生(せんせい)が日本語(にほんご)の先生(せんせい)です。(Take Sensei is the Japanese teacher.)
Here, 「が」 helps identify Take Sensei as the particular person the speaker is referring to.
⑤「は」and 「が」 can appear in the SAME sentence!
「は」 and「が」can even appear in the same sentence, which is one reason why it can be confusing to think of 「は」 simply as the subject marker.
For example
🐘象(ぞう)は鼻(はな)が長(なが)いです。(Elephants have long noses.)
In this sentence,「 象(ぞう)は」tells us what we are talking about, while 「鼻(はな)が長(なが)いです」 tells us something about elephants.
So even though the natural English translation is simply “Elephants have long noses,” the Japanese sentence has two different parts.
「は」 introduces elephants as the overall topic, while 「が」 is used within the information being given about them.
This is a good example of why「は」and「が」should not always be understood simply by translating them directly into English.
They can play different roles in the same Japanese sentence.
どうでしたか。(How’s my explanation?)
日本語(にほんご)は難(むずか)しいですが、おもしろいですよね😊
The more Japanese you hear and read, the more natural the difference will start to feel.🔍
I hope you enjoy learning and speaking Japanese! 👍✨
