Kaku-kaku (written variously in Japanese depending on the creator or source) is an onomatopoeic term. In everyday terms, it points to movement or motion that isn’t smooth—something that feels staggered, stop-start, or mechanical.
If you’ve ever seen an object or character move in a way that looks like it’s skipping frames—like a choppy animation loop—you’re already close to the vibe. Kaku-kaku suggests that kind of jerky pacing, where each motion happens in small bursts rather than one continuous flow.
Importantly, translations can vary. One source might render it as “jerkily,” another as “stiffly,” and another as “clicky” depending on the scene. But the center of gravity is the same: non-smooth motion.
