Japanese Onomatopoeia: Sound Words and Their Meaning Explained
A Complete Guide to Japanese Onomatopoeia

Japanese onomatopoeia, also known as オノマトペ is one of the most fascinating and expressive parts of the language.
Far beyond the typical “bang” or “meow” you might find in English, Japanese has a vast and nuanced system of sound-based words that describe everything from animal noises to emotional states.
These words aren’t just found in manga and anime—they’re part of everyday speech, used to vividly describe feelings, actions, textures, and even silence.
In this guide, we’ll explore the different categories of Japanese onomatopoeia

Japanese Onomatopoeia Words || Introduction
Onomatopoeia in Japanese is called オノマトペ in Japanese.

Japanese is a particularly rich language in onomatopoeia, and the Japanese Onomatopoeia Dictionary contains as many as 4,500 words of onomatopoeia.
Considering that English has 1,000 to 1,500 onomatopoeia and French has about 600, it is clear that Japanese has an extremely large number of onomatopoeia.
Onomatopoeia is frequently used in everyday conversation and is also an important part of the techniques of expression in cartoons and other forms of expression.
Why is there so much onomatopoeia in the Japanese language? One reason is that Japanese verbs express only the basic meaning of actions.
For example, the verbs look, see, witness, gaze, and glance in English are basically translated as 見る みる miru in Japanese.
Of course, each verb is translated according to its nuance, and onomatopoeia is used for this purpose.
For example, gaze is じっと見る じっとみる jitto miru and glance is ちらっと見る ちらっとみる chiratto miru.
Such onomatopoeia is frequently used in manga. Not only the characters just gazing at someone, onomatopoeia such as じっ ji is also written on the screen as a sound effect. The abundance of onomatopoeia may also be closely linked to the development of manga in Japan.
By increasing your knowledge of Japanese onomatopoeia, you will be able to enjoy anime and manga even more.
Linguist Kindaichi Haruhiko – 金田一春彦 きんだいちはるひこ classified onomatopoeia into five types.
The five categories are: those that represent human or animal voices, those that represent sounds in nature, those that represent the state of inanimate objects, those that represent the state of living things, and those that relate to a person’s psychological state or spirit.
In the following sections, we will look at what each of these categories includes according to this classification.

A dog’s cry is considered a “wan-wan” and a cat’s a “nya-nya.”
Puppies are sometimes referred to as “wanko” in Japanese, which is an onomatopoeic word “wan” for the sound of a puppy’s cry, with the diminutive “ko” added.
The clucking sound of a chicken is “koke-kokko.” When you say “koke-kokko,” Japanese people immediately think of chickens.
A baby’s cry is “ogya,” and birth is often described as “born with a cry of ogya” in Japanese.
“Gera gera” represents laughing in a somewhat vulgar way. “Pecha kucha” also represents chatter, and it implies that they are wasting time and talking nonsense.

Onomatopoeia about emotions is the most effective way to show emotions in a dynamic way. Japanese people are sometimes said to be poor at expressing emotions, and this may be partly due to the fact that in Japanese, emotions are expressed through onomatopoeia, which is difficult to translate into English.
Onomatopoeic expressions tend to be avoided in official situations. However, in casual situations, they are very useful because they can intuitively express feelings and emotions.
Unlike kanji, onomatopoeia is not something that has a clear reason for being expressed that way.
Therefore, it is necessary to accumulate one’s own understanding of onomatopoeia by coming into contact with many examples of actual usage.
The onomatopoeia introduced here are just a few examples. Did you find something you liked? Let’s start by learning the onomatopoeia that fits your own sense!
