Have you ever seen dark clouds gathering before a storm?
Or admired someone’s thick, jet-black hair shining in the sunlight?
Japanese has a vivid expression for scenes like these:
“Kuro Guro” (くろぐろ / 黒々)
Although it isn’t considered a true Japanese onomatopoeia, it shares something important with one.
Let’s hear how it sounds!
What is “Kuro Guro” (くろぐろ / 黒々)?
“Kuro Guro” describes:
- A deep, rich black color

Cultural Note
“Kuro Guro” is not considered a traditional Japanese onomatopoeia.
Instead, it belongs to what we call Almost Onomatopoeia—expressions that aren’t true onomatopoeia but feel surprisingly similar.
Like many Japanese onomatopoeic words, “kuro guro” repeats its sounds to make an image more vivid.
Rather than simply describing something as black, it emphasizes depth, richness, and a strong visual presence.
It suggests:
Depth
Strength
A vivid visual impression
