In Japanese, converting from normal sentence to question is pretty easy, as long as you know to add the particle, “Ka” at the end of the sentence.

“Ka”- “か”　is the key particle in Japanese when you are asking questions.  You will need to add “Ka”- “か” at the end of the sentence. Word order will not change.  See below.

これは、あなたの帽子です。　（これは、あなたのぼうしです。）

Korewa anatano boushi desu.  (This is your hat.)

This sentence turns into a question when you add “Ka”=”か” at the end of the sentence.

これは、あなたの帽子ですか。　（これは、あなたのぼうしですか。）

Korewa anatano boushi desu ka.  (Is this your hat?)

It’s pretty easy, right?  In Japanese, we typically don’t use ? (Question Mark) at the end of each sentence.  We end the questions with Maru (。) even for questions.

Japanese might be considered one of the hardest languages to learn, but there are some aspects of learning Japanese, that is pretty easy as well. This grammar rule is one of them for sure! 🙂

Let’s go over some more examples to get used to this particle.

Transparent has a great tutorial video to explain this.
