Intro: quick answer
what does kaku kaku mean? Short answer: it depends on context, most often a Japanese onomatopoeia for something feeling angular, stiff, or choppy, and sometimes part of the phrase “kakukaku shikajika” that means “such and such.”
Okay so, that sounds abstract. Stick with me. Kaku kaku pops up in anime reaction posts, gaming threads, and casual Japanese speech, and it has a few flavors. You will hear it used to complain about lag, describe an awkward movement, or as a narrative shorthand in older Japanese phrases.

What Does Kaku Kaku Mean: Main Meanings
When someone asks what does kaku kaku mean, they usually want one of three senses. First, カクカク describes a jerky, stuttering motion: think low frame rate video, or a robot moving like it has bad joints.
Second, かくかく can mean “angular” or “rigid,” like a drawing with hard corners or a stiff posture. Third, in the phrase かくかくしかじか, which is old-school Japanese, it functions as a filler meaning “such and such” when summarizing a story. All of these share a feeling of rigidity or clipped detail.
What Does Kaku Kaku Mean in Gaming and Video
If you hang out in gaming Discords or watch anime clips, you will frequently see カクカク used to complain about framerate. Someone streams a boss fight and it looks like a slideshow? Commenters type “カクカクしてる” or “kaku kaku” to call out the choppiness.
English equivalents are “laggy,” “choppy,” or “stuttering.” So if you see a tweet like “この動画カクカクだわ” that means “this video is choppy.” It became common on Japanese Twitter and gamer forums once streaming and emulation got mainstream.
Origins and Etymology
The term is onomatopoeic, part of the broad class of Japanese mimetic words that describe sound, motion, or feeling. If you want a primer on Japanese onomatopoeia, Tofugu has a tidy guide that explains giongo and gitaigo, which is useful background: Tofugu on Japanese onomatopoeia.
For the English-side definition of onomatopoeia, look at the Merriam-Webster entry: Merriam-Webster. And if you want to read a general overview, Wikipedia’s onomatopoeia article gives the linguistic framing: Wikipedia: Onomatopoeia.
Examples in Conversation
People actually use kaku kaku in casual chat. Here are real-feeling examples, with translations so you can steal them for your messages.
Tweet: 昨日の配信めっちゃカクカクだった、音ズレも酷い。Translation: Yesterday’s stream was super kaku kaku, and the audio was out of sync too.
Chat: そのアニメ、作画は綺麗だけど動きがカクカク。Translation: That anime has pretty drawings, but the movement is kaku kaku.
Conversation: A: どうして早口？ B: かくかくしかじかで端折った。Translation: A: Why did you rush? B: Long story short, such-and-such, I cut details. (Here かくかくしかじか works like “such and such.”)
Ngl, the gaming example is the one you will see most online. People type カクカク in replies like an instant complaint. It is as common as saying “lag” on English streams.
How to Use Kaku Kaku Like a Native
If you want to use kaku kaku in Japanese chat, remember to match tone and script. Use カクカク in casual posts about video or animation lag. Use かくかくしかじか if you want to be a bit old-school or jokingly vague about a story.
Examples to drop into convo: “これカクカクしてるから設定落としたほうがいい” meaning “this is kaku kaku so you should lower the settings,” or “その話、かくかくしかじかで終わった” meaning “that story ended up as such-and-such.” Sounds natural, honest.
Common Mistakes and Similar Words
People sometimes confuse kaku kaku with kakko kakko or kakko-shiki which is different. Also, the English speakers who just romanize Japanese might type “kakukaku” without spacing. That is fine, native readers get it.
Another mix-up is treating kaku kaku like a direct noun in English. It is better to use it as an adjective or a mimetic verb phrase in Japanese contexts. Say “the video is kaku kaku” only among friends who know the term.
Final Thoughts
So, what does kaku kaku mean? It is a small, flexible mimetic word that usually flags stiffness, angularity, or choppiness, and sometimes surfaces in the idiomatic かくかくしかじか. Once you recognize the contexts, you will spot it everywhere from anime replies to stream complaints.
