- Turn a sentence into a question by adding か at the end: これはすしですか.
- The question word goes where the answer will go. No need to move it to the front.
- Core words: なに (what), だれ (who), どこ (where), いつ (when), どうして (why), いくら (how much).
- Question words take が, never は, as subjects: だれがきましたか.
Making questions with か
Japanese questions are easy: take a statement and add か. No change in word order.
- これはすしですkore wa sushi desuThis is sushi.
- これはすしですかkore wa sushi desu kaIs this sushi?
In casual speech, people often drop か and simply raise their voice: すし?

“Where is the station?”
“How much is it?”
“Who came?”

Frequently asked questions
How do you ask a question in Japanese?
Add the particle か to the end of a sentence: これはすしです (this is sushi) becomes これはすしですか (is this sushi?). In casual speech, rising intonation alone is enough.
What are the Japanese question words?
なに/なん (what), だれ (who), どこ (where), いつ (when), どれ (which), どう (how), どうして/なぜ (why), いくら (how much) and いくつ (how many / how old).
What is the difference between nani and nan?
Both mean 'what'. なん is used before sounds like d, n and t and before counters (なんですか, なんじ), なに elsewhere (なにがすきですか).
