Questions without か: の?, っけ, でしょ? and a rising voice
Casual Japanese questions usually drop か. Learn how の? asks for an explanation, how っけ checks your memory, and how でしょ? asks for agreement.

Where did か go?
Textbooks teach one simple rule: add か to the end of a sentence and it becomes a question. 行きますか? means "Are you going?" and 学生ですか? means "Are you a student?" The rule is correct, but it describes polite speech. Among friends, family, and comedy partners, most questions have no か at all. They end in の?, っけ or でしょ?, or they are plain statements said with a rising voice.
The counts below come from machine-made transcripts of the 1,905 routines in our library, so treat them as rough guides rather than exact figures.
か is alive, but mostly polite
か has not disappeared. In our library, lines ending in か? appear on 2,373 lines. Many of those are polite questions: どうですか?, いいんですか?, or the clipped junior-style すか (see 〜っす). In speech, か is most at home after です and ます.
か after a plain form is a different story. 行くか? or 本当か? sounds blunt, and in everyday speech it is traditionally associated with a rougher, more masculine style. Plain か with a falling voice often has a different job altogether. It can be a suggestion (帰るか, "shall we head home"), or someone talking to themselves (そうか, "I see").
A rising voice is enough
The simplest casual question is a plain statement with the pitch going up at the end:
- 行く? (Are you going?)
- これ、食べる? (Want to eat this?)
- 学生? (Are you a student?)
- 寒い? (Are you cold?)
The words are identical to the statement. Only the intonation tells you it is a question. One trap: you cannot keep だ in a rising question. 学生だ? is not natural, so drop the だ and say just 学生?
Short reactions work the same way. なにそれ? ("What's that?!") has no particle at all, and it is a classic line a comedian fires at a partner's strange idea. See なにそれ.
の?: "what's the story?"
One of the most common replacements for か is の?. Lines ending in の? appear on 2,458 lines in our library, from 224 of the 283 comedians. That is about as many lines as end in か?, roughly 1 to 1.
の? is the casual form of んですか. Like んですか, it does more than ask yes or no. It asks for an explanation of the situation in front of you:
- どうしたの? (What happened? / What's wrong?)
- 行かないの? (You're not going? How come?)
- なんで泣いてるの? (Why are you crying?)
After a noun or a な-adjective, insert な: カフェなの? ("It's a café?"), 好きなの? ("You like it?").
Because の? asks "what's going on here?", it suits the reactions of a straight man to a partner's nonsense. A なんで at the front turns it into a challenge: なんで〜の? ("Why on earth would you…?"). Combine it with the contractions from our note on casual contractions and you get 何してんの?, which ranges from a friendly "what are you up to?" to a sharp "what are you doing?!" depending on the tone. See 〜てんの?.
The rough version is のか?. Aimed at someone instead of の?, it can sound pushy or confrontational.
っけ: "…again?"
っけ is what you add when you know you once knew something but can't remember it now. It most often appears as だっけ or as たっけ after a past form. With a plain present verb, use んだっけ (行くんだっけ?) rather than adding っけ directly:
- 名前、なんだっけ? (What was your name again?)
- 会議って明日だっけ? (The meeting's tomorrow, right? Or was it…?)
- どこに置いたっけ? (Where did I put it?)
The last example is often muttered to yourself rather than asked. In comedy, っけ shows up when a character fakes a memory lapse or checks a detail that doesn't add up. It also has a polite form, でしたっけ or ましたっけ, which works with coworkers: お名前、何でしたっけ? ("Sorry, what was your name again?").
We won't give a count for っけ here. In the transcripts, the same letters also appear in かっけー ("cool"), 高っけえ ("pricey") and 乗っけた ("put on top"), so the raw number overstates it. Browse lines with なんだっけ and でしたっけ instead. More on 〜でしたっけ?.
One person learns that a friend failed the college entrance exam, yet the friend is here anyway.
いいんだっけー
Wait, is that allowed again?
Textbookそれでいいのでしたか?「いいのでしたか」 becomes 「いいんだっけ」: 「の」 shrinks to 「ん」, 「でした」 turns plain 「だ」, and 「っけ」 checks a half-remembered rule.
でしょ?: "right?"
でしょ is the shortened でしょう. Textbooks teach でしょう as "probably", but in casual questions it does something else. With a rising voice, it asks the listener to agree with something the speaker already believes:
- かわいいでしょ? (Cute, right?)
- 覚えてるでしょ? (You remember, don't you?)
- 行くんでしょ? (You're going, aren't you?)
In our library, でしょ? appears on 314 lines from 113 comedians.
With a falling or pressing tone, the same でしょ stops being a question and becomes "See? I told you" or "Obviously!": 違うでしょ! ("That's wrong, obviously!"). It also appears in うそでしょ ("No way!"; see うそ!/うそでしょ). The rougher partner of でしょ is だろ, which sounds blunter and is common in comebacks; see 〜だろ!.
Someone explains why they won't switch to an electronic wind instrument, then complains about tax increases.
Culture note Japan's consumption tax has been raised several times, and people often complain about it.
今ドからファまで税金でしょ
These days, Do through Fa is all tax, right?
Textbook今はドからファまで税金でしょう?「でしょう」 clips to 「でしょ」, presenting a fact the listener should already know: 'it's all tax now, right?'
Using them yourself
- Rising voice (行く?, 学生?): fine with friends, family, and anyone you already speak casually with. With a boss or a stranger, keep the です/ます form: 行きますか?
- の?: casual. Its polite partner is んですか, as in どうしたんですか? That form is fine at work and is one of the most useful patterns to learn. Avoid のか? unless you want to sound confrontational.
- っけ: だっけ is for friends. でしたっけ is fine with coworkers and is a soft way to admit you forgot something. With someone very senior, a fuller apology is safer: 失礼ですが、お名前は…
- でしょ?: for friends and family. It presumes agreement, so it can sound presumptuous to a superior. Use ですよね? with them instead. だろ is rougher and best kept to close friends, or left for listening only.
- Plain か (行くか?): blunt. Understand it, but as a learner you rarely need to use it as a question.

Try it
- Turn these into casual questions three ways: with a rising voice, with の?, and with でしょ?. 行きますか?, 好きですか?, 知っていますか? Notice how the meaning shifts from "are you…?" to "what's the story?" to "you are, right?"
- Search the library for でしょ and だっけ. For each line, decide whether the speaker is asking or insisting.
- Watch the scenes on 〜てんの? and なにそれ, and repeat each question with the same rise in pitch.
