7 Japanese Question Words and Examples

Certainly, it’s more helpful to learn question words in context. Once you start understanding the use of each question word in everyday life, you’ll quickly learn them by heart. Let’s take a look at the common question phrases in Japanese.

What in Japanese

The question “what” can be expressed in 2 ways. It can be なに (nani) or なん (nan). Although, they both mean “what”, there can be a difference in usage.

なに (nani) can be used without being attached to other Japanese words and it can’t be used with ですか (desu ka). On the other hand, なん (nan) can’t stand alone so it needs to be attached with ですか (desu ka). Let’s take a look at the examples below:


(あなたのなまえはなんですか | Anata no namae wa nan desuka?)

What is your name?


(なにかこまっていますか | Nanika komatte imasuka?)

What is the matter? May I help you?

Where in Japanese

どこ (doko) is used to ask “where”. It is written as 何処 in Kanji. Here are some examples:


Dokokara kima shitaka?

Where are you from?


(どこ に すんでいます か? | Doko ni sunde imasuka?)

Where do you live?

When in Japanese

If you’re going to ask for time or date, you can use the Japanese word いつ (itsu). Here’s how to use the question word いつ (itsu):


(いつ から にほんご を べんきょうしています か? | Itsu kara Nihongo wo Benkyou shiteimasuka?)

Since when have you been studying Japanese?


(つぎ の れっすん は い つ です か? | Tsugi no ressun wa itsu desuka?)

Why in Japanese

The question word “why” can be expressed in 3 ways. なぜ (naze), なんで (nande) and どうして (doushite) are used to say “why”. The difference among these words is based on emotions and rationality.

なぜ (naze) is used when asking about reason or motive and cause. どうして (doushite) can also be used for asking about reason or motive but is also used to ask for method or process. なんで (nande) can be used as なぜ (naze) and どうして (doushite) are used. However, it’s important to note that なぜ (naze) and なんで (nande) are commonly used in conversations as they are less formal. どうして (doushite) is less used since it is a formal word for “why”.


(なぜ にほんご を べんきょうしている の です か? | Naze Nihongo wo benkyou shiteiruno desuka?)

Why do you study Japanese?


(どうして にっぽん に きた の です か? | Doushite Nihon ni kitano desuka?)

Who or Whom in Japanese

When asking for the questions who and whom in Japanese, you’ll use だれ (dare). Here are some examples:


(あの ひと は だれ です か? | Anohito wa dare desuka?)

Who is the person over there?


(だれ と いっしょ に きました か? | Dare to isshoni kima shitaka?)

With whom did you come with?

Which in Japanese

There are 3 ways to say which in Japanese. You can say it as どれ (dore) or どちら (dochira) or どちらの (dochira no) or どの (dono).

どれ (dore) and どちら (dochira) both mean “which” but どちら (dochira) is the polite form. However, in usage, どれ (dore) is used when there are 3 or more options to choose from. どちら (dochira), on the other hand, is used when there are 2 things to choose from.

どの (dono) is also used when there are more than 2 choices, but it functions as an adjective. It is used when asking which noun. It follows the form “どの (dono) + noun”. どちらの (dochira no) can mean “whichever”.


(どの えき に いきたい です か? | Dono Eki ni ikitai desuka? )

Which station do you want to go?


Dochira ga anata no kaban desuka?

Which is your bag?

Whose in Japanese

The word だれの (dareno) is used when you’re asking for the who the owner of an object. Here are sample sentences for だれの (dareno).

Whose passport did you lose?

How in Japanese

There are 3 ways to ask “how” in Japanese. You can say it as どう(dou), どうやって (dou yatte), or どのように (dono youni). どう(dou) can simply be used when asking how are things.

On the other hand, どのように and どうやって are both question words used to ask “how” to do something. The only difference between the two Japanese phrases is in their formality level. どのように is more formal (and polite) than どうやって.


Kore wa dou desu ka?

How is this?


Kokomade dou yatte kimashitaka?
