1. Intro to Japanese Question Words

There are 9 main Japanese question words that cover who, what, when, where, why, and which. Some words have multiple options compared to English — hence 9 words. So, you’ll need to know which one to use.

An important difference between English and Japanese question words is that you have to maneuver the politeness of each phrase depending on who you’re talking with.

As you learn each word, see the example phrases to learn how to make it polite or casual.

2. What – 何

How do you say what in Japanese?

The Japanese word for “what” is 何. You can also combine it with a wide range of verbs and particles to create interesting questions. Make sure not to use this word for making interjections like “what?!”. Although you’ll hear this in manga and anime, it can be weird for daily speech. 何 can have two different pronunciations, nani or nan, that are used in certain phrases to make it flow better. However, both mean the same thing.

  • 何?
    • What? (casual)
    • Nani?
  • 何ですか?
    • What is it? (polite)
    • Nan desuka?
  • 何食べたい?
    • What do you want to eat? (casual)
    • Nani tabetai?
  • 何を食べたいですか?
    • What do you want to eat (polite)
    • Nani o tabetai desu ka?

By the way, a common question you’ll need to know is… “What’s your name?” So, here’s how you say it in Japanese.

  • 名前は何ですか?
  • Namae wa nan desu ka?

3. Who – 誰

Let’s start with one of the most common Japanese words.

This is the word for when you want to make a “who” question sentence. You can combine it with a variety of verbs and particles to ask specific questions. The last two examples show how it can be combined with the verb “to come”, or 来る (kuru). Try making your own sentences by adding a verb that you know. It’s also good to understand that 誰 (dare) can sometimes be used to talk about no one, someone, or everyone. For example, 誰もいない (dare mo inai) means “no one is here”. Don’t get confused if you see it in a different context than a question phrase.

  • 誰?
    • Who? (casual)
    • Dare?
  • 誰ですか?
    • Who is it? (polite)
    • Dare desu ka?
  • 誰が来るの?
    • Who is coming? (casual)
    • Dare ga kuru no?
  • 誰が来ますか?
    • Who is coming (polite)
    • Dare ga kimasu ka?

4. When – いつ

Use the “when” question word to find out about someone’s past, to make plans, and more. Combining the question word with a verb like 行くor “to go” can be a great way to ask about upcoming travel. This question word also makes up other phrases that mean different things from “when”. For example, いつも (itsumo) means “always”, いつでも (itsudemo) means “whenever”, and いつか (itsuka) can mean “someday”.

  • いつ?
    • When? (casual)
    • itsu?
  • いつですか?
    • When is it? (polite)
    • Itsu desu ka?
  • いつ行くの?
    • When are you going? (casual)
    • Itsu iku no?
  • いつ行きますか?
    • When are you going? (polite)
    • Itsu iki masuka?

5. Where – どこ

If you somehow find yourself lost in Japan, you’ll find that “where” is a lifesaver. This word can be used as a way to form many different sentences to ask about locations. To ask for specific locations, you can add the location at the beginning followed by はどこ?(wa doko?). どこ (doko) is also a great icebreaker word when you want to know where someone lives or comes from.

  • どこ?
    • Where? (casual)
    • Doko?
  • どこですか?
    • Where is it? (polite)
    • Doko desu ka?
  • どこに住んでるの?
    • Where do you live (casual)
    • Doko ni sunderu no?
  • どこに住んでいますか?
    • Where do you live (polite)
    • Doko ni sunde imasu ka?

With “why”, there are two main options that you can use. なぜ (naze) sounds formal or old fashioned. なんで (nande) is more casual. However, both words can be used in both situations. By changing up the phrasing, you can make it sound polite or casual. These question words are highly recommended if you want to have a conversation with someone. Asking “why” is a great way to have someone elaborate on a topic and you’ll learn more about them.

7. Which – どれ / どっち / どちら

How do you say which in Japanese?

Well, this is one of the more complicated question words in Japanese. There are 3 main ways to say “which.” First, there’s どれ (dore) which is the most neutral “which” word that fits into both casual and polite situations. Then, どっち (docchi) has a more casual connotation. Then, どちら (dochira) sounds a bit more formal. If you’re asking for direction, like asking “which way is it?”, you can only use どっち (docchi) or どちら (dochira). Knowing how to use these in the right situations takes practice and listening to native speakers.

  • どれが好き?
    • Which do you like? (casual)
    • Dore ga suki?
  • 銀行はどちらですか?
    • Which way is the bank? (polite)
    • Ginkou wa dochira desu ka?
  • どっちの方が可愛い?
    • Which is cuter? (casual)
    • Docchi no hou ga kawaii?
  • どっちの方が可愛いですか?
    • Which is cuter? (polite)
    • Docchi no hou ga kawaii desu ka?
