Japanese Question Word Markers & the ka (か) Particle (in romaji)

If you’re like me and mostly want to speak Japanese, not read or write it, this post is for you. Everything here is written in romaji (the Romanized version of Japanese). If you’re interested in learning hiragana, katakana, or kanji, I recommend using other resources, or even asking ChatGPT for a custom plan.
(Feel free to check out the r/languagelearning and r/LearnJapanese subreddits for extra resources or recommendations).

πŸ”° I don’t have any certificates, just a learner sharing what I know, so if I get something wrong, feel free to double-check or correct me!

πŸ’¬ I’m still learning Japanese too, (on my journey from bronze to grandmaster), I document everything in my weekly language progress logs.
Every week I post a page with:

  • A short speaking video or update
  • My test assessment
  • Notes and improvements
  • What rank I’m at (from Bronze to Grandmaster)

Most questions in Japanese will end with the ka (か) particle, think of it as the equivalent of a question mark in English. It always comes at the end of the sentence, even after polite endings like desu or masu, except when using kudasai, where it’s not typically used.

🧠 The only particle that comes after “ka” is “na”, used in ka na phrases when wondering or thinking out loud, or to oneself:
Nani ka na… – I wonder what it is.

✨ There are also confirmation tags like ne, na, and deshou that can form questions without using ka, but those are for another page.

πŸ—£οΈ Tone of Voice

When asking a question, your intonation should rise at the end, much like English. This helps indicate you’re asking a question even in informal speech when ka is dropped.

Examples:

  • Nan sai desu ka? – How old are you?
  • Namae wa nan desu ka? – What’s your name?
  • Kore, tabemasu ka? – Do you want to eat this?
  • Ashita, Tokyo ni ikimasu ka? – Are you going to Tokyo tomorrow?

🧠 β€œNani” (what) often changes to β€œnan” before certain consonants like d, t, n, or j. This change isn’t a grammar rule, but rather a pronunciation adjustment.

Japanese naturally favors smooth, rhythmic speech, so nani shortens to nan in cases where saying “nani” followed by one of these sounds would feel clunky or unnatural.

Examples:

  • Nan desu ka? – What is it?
  • Nan ji desu ka? – What time is it?
  • Nan to iu? – What did (they) say?

When followed by particles or softer sounds, nani usually stays as-is:

  • Nani wo tabemasu ka? – What will you eat?
  • Nani ga suki desu ka? – What do you like?

πŸ”Š In very informal speech, ka can be dropped because the question word alone makes it obvious that you’re asking something. But be careful, omitting ka can come off as rude or blunt unless you’re in a casual setting or with close friends.

  • Fix the β€œNan desu ka = How old are you” mix-up
  • Use a clearer β€œnan” example like Nan ji desu ka?
  • Update small typos and polish wording slightly

🧠 Practice Tips:

  • Use ChatGPT to quiz you on making sentences.
  • Try making your own sentences and get feedback!
