The Hidden Language of
Japanese Onomatopoeia
ใใชใณใใใชใณโฆchirin, chirin...
We already know what onomatopoeia is.
...or do we?
When you hear the word onomatopoeia, what comes to mind?
Maybe something like this.
These words imitate sounds.
That's how the English Comics usually uses onomatopoeia.
So naturally, we expect manga to work the same way.
But let's look a little closer.

Yes, Onomatopoeia represents sounds, like the sound of metal falling,
the cry of a child, the loud laughter of a group.

Japanese manga, however, uses onomatopoeia to capture much more than what we hear.
These expressive words describe voices, nature and object sounds, movement, appearance, texture, feelings, atmosphere, and situationsโgiving language to experiences that are often left unspoken. Instead of simply asking, "What does this sound like?" Japanese manga asks, "What does this moment feel like?" At first glance, they all look like sound effects, but many are actually used to express movement, emotion, atmosphere, texture, and other sensory experiences.
Let's see how much is actually sound.

The majority of manga onomatopoeia isn't describing sounds.
It is describing perception.

Sound is only one part of the language..
Breaking down the language
How Japanese manga categorizes everyday experiences?
Beyond Sound: The Five Faces of Japanese Onomatopoeia
Japanese groups onomatopoeia into five linguistic types, each representing a different way of experiencing the world. Two types focus on soundโLiving Voices (Giseigo) and Nature & Object Sounds (Giongo). The remaining three describe perception: States & Appearance (Gitaigo), Movement & Behaviour (Giyougo), and Feelings & Emotions (Gijougo). Together, they show that manga onomatopoeia extends far beyond sound, giving language to movement, texture, atmosphere, and emotion.
The Complete Classification of Japanese Onomatopoeia
Japanese onomatopoeia follows a layered system of classification. Every word first belongs to a semantic category, describing what it representsโsuch as texture, movement, weather, emotions, or human sounds. These categories are then grouped into five linguistic types that we saw above. This classification shows that Japanese onomatopoeia is more than a collection of sound effects.
It's a structured system for expressing how the world is experienced.

Japanese manga uses onomatopoeia as more than a way to imitate soundsโit uses it to communicate the texture of everyday life. From a quiet sparkle to a racing heartbeat or the feeling of hesitation, these expressive words capture experiences that often have no direct equivalent in English. Through this rich classification system, Japanese onomatopoeia demonstrates that language can represent not only what we hear, but also what we see, feel, and perceive.
Footnote
This project began with a simple question: Are manga onomatopoeia really just sound effects? While exploring the language, I discovered that many of these words describe experiences that have no sound at allโfeelings, movement, texture, atmosphere, and appearance. Rather than presenting a comprehensive linguistic study, this project aims to visualize one aspect of how Japanese manga uses onomatopoeia to express perception, making a complex language system more accessible through data storytelling.

Disclaimer
The classifications and visual groupings presented in this project are based on the editorial taxonomy provided by Ono.Jepang.org and have been simplified to support visual storytelling. Some onomatopoeic expressions can overlap across meanings or linguistic functions, so the visualizations are intended to communicate broader patterns rather than definitive linguistic rules.
