は and が: a practical first distinction
Both は and が can follow a noun, but they guide the listener differently. Use topic, identification, and context to make a practical first choice.

MAP NOTES
What to take with you
- は sets the topic or creates a contrast
- が often identifies what or who fits the description
- The natural choice depends on what is already known in the conversation
は tells us what we are talking about
In わたしは 学生です, は presents わたし as the topic. The sentence then says something about that topic. は can also create contrast, as in コーヒーは 飲みます, which may imply that another drink is different.
が can identify the answer
When someone asks だれが 来ましたか, the unknown information is “who.” The answer 田中さんが 来ました identifies that person. が also appears naturally with descriptions such as 日本語が 好きです.
Context decides more than translation
Both particles may be possible in grammatically correct sentences while creating a different focus. Do not memorize “は equals is” or “が equals subject.” Listen for what the conversation already knows and what the speaker is adding.
Use a first-pass decision
Choose は when you establish or return to a topic. Choose が when you identify the person or thing that answers a question, or when a common pattern requires it. Refine this distinction as you meet more real examples.
