は and が are foundational Japanese particles. The difference becomes clearer if you think about information flow.
What does は vs が mean?
は marks the topic: it tells the listener what the sentence is about. Natural translations include “as for…” or “speaking of…”.
が marks the subject, especially when it is new, important, or the answer to an implied question. It often carries the feeling of “this one” or “this person”.
Together, these two particles manage the flow of information in nearly every Japanese sentence.
How to form は vs が
Both particles attach directly to nouns and noun phrases.
There is no conjugation. Place the particle after the word you want to mark.
When is は vs が used?
は marks the topic
Use は when you want to say what the sentence is about. It sets the stage for whatever comes next.
が marks the subject you are identifying
Use が when the subject is new, important, or the answer to an implied question. It points out the specific person or thing doing the action.
Tone and register:
- Foundational; used in every register from casual speech to formal writing
- Essential for JLPT N5 listening and reading comprehension
は vs が example sentences
After reading each sentence, ask what job the particle is doing: setting a topic or identifying a subject.
Nuance of は vs が
The key nuance is information flow.
は sets the stage. It tells the listener, “This is what I am talking about.” Everything after it is a comment on that topic.
が delivers the new information. In an answer to a question, it singles out the one thing the listener does not yet know.
If you can translate the feeling as “speaking of…”, try は. If you are pointing out “this one / this person”, try が.
は vs が vs も
Both は and が single out one item in the sentence, but they do different jobs. も is another particle that resembles them in placement yet changes the meaning entirely.
If you need to mark a topic, use は. If you need to identify a subject, use が. If you mean “also”, use も.
Common mistakes with は vs が
A helpful practice method is to take one sentence and swap the particle, then explain how the meaning shifts.
Is は vs が on the JLPT?
Yes. は and が appear in JLPT N5 as core particle questions.
For test preparation, study the grammar point in full sentences. JLPT questions often test whether you understand the surrounding context, not just the dictionary meaning.
Practice questions for は vs が
