The Japanese particle が is commonly used after question words when asking who or what performs an action, exists in a particular place, or is being identified.
The most common question words used with the Japanese particle が are:
| Japanese | Romaji | Meaning |
|---|---|---|
| 誰 | dare | who |
| 何 | nani / nan | what |
| どれ | dore | which one |
| どの | dono | which + noun |
| どこ | doko | where |
The basic pattern is:
Question word + Japanese particle が + Predicate
For example:
誰が来ましたか。
Dare ga kimashita ka?
Who came?
Here, 誰 (dare) asks for the identity of the person who came, and the Japanese particle が marks that person as the subject.

How to Use the Japanese Particle が With どの
どの (dono) means “which” and must be followed by a noun.

How the Japanese Particle が Identifies the Answer
A particularly important pattern is:
Question word + が + Predicate
followed by:
Specific noun + が + Predicate
For example:
誰が先生ですか。
Dare ga sensei desu ka?
Who is the teacher?
田中さんが先生です。
Tanaka-san ga sensei desu.
Tanaka is the teacher.
The question asks for the subject. The answer identifies the subject.
Another example:
どれがあなたのかばんですか。
Dore ga anata no kaban desu ka?
Which one is your bag?
これが私のかばんです。
Kore ga watashi no kaban desu.
This is my bag.
This is one of the clearest situations in which the Japanese particle が marks the information being identified.

Japanese Particle が and は With Question Words
Question words provide an important example of the difference between the Japanese particles が and は.
Compare:
誰が来ましたか。
Dare ga kimashita ka?
Who came?
誰は来ましたか。
Dare wa kimashita ka?
The first sentence asks which person came and is the normal structure for this question.
The Japanese particle は does not simply replace が here. は marks a topic and can introduce contrast or a specific topic under discussion.
For example:
田中さんは来ましたか。
Tanaka-san wa kimashita ka?
Did Tanaka come?
This question already establishes 田中さん (Tanaka-san) as the topic. It asks about that person’s participation.
By contrast:
誰が来ましたか。
Dare ga kimashita ka?
Who came?
This asks for the identity of the person who came.

Common Mistakes With the Japanese Particle が and Question Words
One common mistake is confusing どれ and どの.
どれ can stand alone:
どれが好きですか。
Dore ga suki desu ka?
Which one do you like?
どの must be followed by a noun:
どの本が好きですか。
Dono hon ga suki desu ka?
Which book do you like?
Another mistake is using は simply because the English question contains “who” or “what.” Japanese particle choice depends on the grammatical role of the question word and the information structure of the sentence.
A third mistake is forgetting that the answer to a question using 誰が, 何が, or どれが commonly uses the Japanese particle が as well.
