がga“subject marker”

が is the particle that marks the subject of a sentence: the person or thing that does the action, exists, or has a quality. It also marks the thing you like, want, understand, or are good at. Most importantly, が points at new or answering information, which is what makes it different from は.

If a question uses 誰(だれ)が or 何(なに)が, the answer uses が too. That one habit fixes half of all beginner は/が mistakes.

What does が mean?

が has no English translation of its own. It is a label that says “this word is the subject.” In 雨(あめ)が降(ふ)っています (“It’s raining”), が marks 雨 as the thing that is falling.

What makes が special is focus. When you use が, you are telling the listener “this is the new part” or “this is the answer.” Compare two ways English could stress a sentence:

• Tanaka is coming (not someone else) → 田中(たなか)さんが来(き)ます
• Tanaka is coming (as for Tanaka, he’s coming) → 田中さんは来ます

At N5 you also need が for a small group of words that describe feelings and abilities rather than actions: 好き (like), きらい (dislike), 上手 (good at), 下手 (bad at), ほしい (want), わかる (understand), and できる (can do). In English the thing you like is an object, but in Japanese it takes が: 音楽(おんがく)が好きです — “I like music.”

You may also meet が between two clauses meaning “but” (高(たか)いですが、おいしいです). That is a different が, a conjunction. This lesson is about the subject marker.

How to form が

が always follows a noun or a pronoun, including question words.

A few rules to remember:

• Question words that are the subject always take が: 誰が, 何が, どれが, どこが. Never 誰は.
• が replaces を with the “feeling and ability” words above: 日本語を好き is non-standard; say 日本語が好き.
• Inside a description of a noun, the subject takes が, not は: 私(わたし)が作(つく)ったケーキ — “the cake I made.”

When is が used?

Use が in these situations:

• Existence: ある and いる almost always pair with が when you introduce something. 駅(えき)の前(まえ)に銀行(ぎんこう)があります.
• Noticing something: when you describe what you see or hear right now, as neutral news. あ、電車(でんしゃ)が来(き)た! (“Oh, the train’s here!”)
• Questions and answers about “who / what”: the question word and the answer both take が.
• Likes, wants, skills, understanding: 好き, ほしい, 上手, わかる, できる.
• Describing a part of the topic: この部屋(へや)は窓(まど)が大(おお)きい — “This room has big windows.” は sets the topic (the room), が marks the part being described.

が is neutral in register. It appears the same way in casual and polite speech. In very casual conversation, speakers sometimes drop it (雨、降ってる), but in writing and on the test you should always include it.

が example sentences

Sentences 5 to 7 use both particles. は sets the topic (me, my sister, this room), and が marks what is liked, what she’s good at, or which part is big. This AはBが pattern is extremely common, so get used to seeing both particles in one sentence.

Nuance of が

The key nuance is identification: が picks out one thing as “the one.” That’s why 私(わたし)が行(い)きます sounds like “I’ll go” — you are volunteering yourself, possibly instead of someone else. 私は行きます is a plain statement about your plans.

This also explains why が can sound wrong in a self-introduction. 私が田中です means “I’m the Tanaka (you were looking for).” It is perfect when someone at a reception desk asks for Tanaka, but strange when you’re just introducing yourself.

With description sentences, が reports a scene without comment. 空(そら)が青(あお)い is a fresh observation (“The sky is blue!”). 空は青い sounds like a general fact or sets up a contrast (“The sky is blue, but…”).

💡 Quick test: Could you add “it’s ~ that…” or stress the word in English? (“It’s Tanaka who’s coming.”) If yes, you probably want が.

が vs は

This is the most tested particle choice in N5. Both can sit after the subject, but they do different jobs.

Notice where the new information sits. With が, the new part is the word before the particle (Yamada-san). With は, the new part comes after the particle (teacher). Let the question guide you: whatever particle the question word used, keep the same slot in your answer. For the full picture, see は vs が basics and the は topic marker lesson.

Common mistakes with が

Is が on the JLPT?

A typical item gives you 部屋(へや)に誰(だれ)（　）いますか and four particle options. The existence verb and the question word both point to が. Listening questions also rely on it: when a speaker says 私が, they are usually telling you who does the task.
