Japanese questions are super easy! All you have to do is add “ka” to the end of the sentence.

Shiba
Question Rule: A wa B desu ka? ( A = B? )
wa :
Topic marker
It marks the subject. Think of it as “As for…”
desu :
am / is / are
The polite ending of the sentence.
ka :
Question marker (?)
Just add it to the end to make a question!

Wow, that’s even simpler than in English! So, how do we make a sentence negative?

Shiba Sensei

You can make a sentence negative by changing “desu” to “dewa arimasen.” It’s a bit long, but you’ll just have to memorize this part!

Watashi wa
I
daigakusei
a university student
dewa arimasen.
am not.
Shiba
Negative Rule: A wa B dewa arimasen ( A ≠ B )
wa :
Topic marker
It marks the subject. Think of it as “As for…”
dewa arimasen :
am not / is not / are not
The polite negative ending of the sentence.

I’ll do my best! By the way, in the manga above, it said “daigakusei de wa arimasen,” and the subject “watashi wa” was missing. Why is that?

Shiba Sensei

Actually, in Japanese, the subject is more often omitted than not. It’s a culture where we expect the listener to “sense” who the subject is, almost like a ninja!

Shiba
Ninja Rule: Subject Omission ( Hide the Subject! )
In Japanese, we often hide the subject like a Ninja.
  • Hide: If the listener already knows who you’re talking about.
  • Show: Only if it’s unclear or you want to emphasize it.
Example 1: Speaking about yourself
(Watashi wa) 日本人にほんじんです。
Nihonjin desu.
I am Japanese.
Example 2: When Ken is already the topic
(Ken wa) カナダじんです。
Kanadajin desu.
Ken is Canadian.
💡 Shiba’s Study Advice

In Japanese language schools and textbooks, the subject is usually not omitted to prevent students from getting confused.

In my lessons, too, we’ll keep the subjects most of the time to help you master the grammar properly!

In the next manga, let’s fill in the pink blanks and read it out loud!

If I remember correctly, I just need to add “ka” to “desu” to make a question, right?

Shiba: Mr. Ken, are you a university student? / Ken: No, I am not a university student.

Shiba: Mr. Ken, are you an office worker? / Ken: No, I am not an office worker.

Shiba: Then… who are you, Mr. Ken?

Now, let’s try to fill in the pink blanks for the negative sentences too!

Shiba: Mr. Ken, are you a university student? / Ken: No, I am not a university student.

Shiba: Mr. Ken, are you an office worker? / Ken: No, I am not an office worker.
