Quick Summary Of The Japanese Question Words

Here is the list of Japanese question words. We will elaborate on each of them as you scroll through the post.


What Japanese Question Words Should You Learn?

Ling Mascot asking Japanese Question Word 何 Nani means What

What? (何,なに,なん) – Nani

The Japanese word for ‘what’ has two forms: nani(なに) and nan(なん). Both of them are written with the same kanji . Nan is used before the copula such as ‘desu’ in Japanese. The Japanese language doesn’t allow movement principle, unlike English. So, usually, the sentence patterns stay the same. We say ‘What is this?’ in English, but when it comes to the Japanese language, you should think ‘This is what?’

Nani? is used more like an exclamation phrase such as ‘What? or Huh?’

Example: これはですか(Kore wa nan desu ka?)

English: What is this?

Example: 何が食べたいですか。(Nani ga tabetai desu ka?)

English: What do you want to eat?

Where? (どこ)

The Japanese question word for ‘Where?’ is doko (どこ). It doesn’t have a kanji version. Doko (どこ) can be answered with the words such as koko (ここ) here, soko (そこ) there, and asoko (あそこ) over there.

Example: トイレはどこですか?(Toire wa doko desu ka?)

English: Where is the bathroom?

Example: どこに行くの? (Doko ni iku no?)

English: Where are you going?

When? (いつ)

The Japanese question word for ‘when’ is itsu (いつ). It’s important to remember that this is only used as a question word. However, you can’t use it as a conjunction because they are expressed in different words, and ‘when’ needs a different grammar structure since it isn’t a question word.

Example: いつ帰りますか? (Itsu kaerimasu ka?)

English: When will you go home?

Example: 誕生日はいつですか? (Tanjyoubi wa itsu desu ka?)

English: When is your birthday?

Ling Mascot Gaia asking Japanese Question Word なぜ/なん Naze/Nande meaning Why

Why? (なぜ / なんで)

The Japanese question word for ‘why’ is nande (なんで). The more formal version is naze (なぜ). Doushite (どうして) can also be used to say ‘why’ but it also means ‘how’ depending on context. So, you must be careful if you want to use that word.

Example: なぜ日本語を勉強するのですか? (Naze nihongo wo benkyou suruno desu ka?)

English: Why do you study Japanese?

Example: なぜあなたはここにいるのですか? (Naze anata wa koko ni iru nodesu ka?)

English: Why are you here?

Ling Mascot asking Japanese Question Wordどう Dou meaning How

How? (どう)

You can use doushite (どうして) or dou (どう) to say ‘how’ in Japanese. You can use dou on its own or you can place it right before a verb.

Example: どうですか?(Dou desu ka?)

English: How is it?

Example: どう思いますか? (Dou omoimasu ka?)

English: What do you think?

Who? (だれ)

In Japanese, the question word for ‘who’ is dare (だれ). The level of formality always stays the same, no matter how many people you’re talking about. You can say dare in any situation.

Example: だれですか? (Dare desu ka?)

English: Who is it?

Example: あの女の子はだれ?(Ano on’nanoko wa dare?)

English: Who is that girl?

Question Mark In Japanese

Japanese punctuation includes various written marks besides characters and numbers, but they differ from those used in European languages. Punctuation is not widely used in formal Japanese writing but is often found in more casual writing, like exclamation and question marks.

Japanese can be written horizontally or vertically, and some punctuation marks adapt to this change in direction. These include parentheses, curved brackets, square quotation marks, ellipses, dashes, and swung dashes, which are rotated clockwise 90° when used in vertical texts.

However, Japanese punctuation marks are usually full-width, so they occupy an area similar to the surrounding characters. Punctuation was not widely used in Japanese writing until translations from European languages became popular in the 19th century.

In formal Japanese, no particular symbol is used to mark question sentences, which end with the normal Japanese full stop (。), but the question mark is commonly used in casual text-based conversations and creative writing and in manga.
