JAPANESE ONOMATOPOEIA
Simply put, Onomatopoeia is the formation of a word from a sound.
These sound words bring life to our conversation. While most languages have onomatopoeic words, Japanese onomatopoeia are much more common.

TYPES OF ONOMATOPOEIA
There are thousands of onomatopoeias in Japanese, but we can divide them into 3 main types or categories.
・Giseigo (擬声語) – Animal and human sounds
・Giongo (擬音語) – Sounds made by inanimate objects and nature
・Gitaigo (擬態語) – Describe the condition and states
INTRODUCTION TO GISEIGO
擬声語
Giseigo
Giseigo are pretty simple and straightforward. They are only used for voice-related sounds made by living things such as animals and humans. Some of them may sound similar to English onomatopoeia, others may sound quite different.
| わんわん | Wan wan | Woof (Dog) |
| ぶーん | Buun | Buzz (Bee) |
| もーもー | Moo moo | Moo (Cow) |
| めーめー | Mee mee | Baa (Sheep) |
| にゃん | Nyan | Meow (Cat) |
| あはは | Ahaha | Hahaha (Laugh) |
| うわーん | Uwaan | Baby or Child crying loudly |
| うぎゃー | Ugyaa | A surprised scream |
INTRODUCTION TO GITAIGO
擬態語
Gitaigo
Gitaigo are slightly different from the other 2 types of Japanese onomatopoeia.
Rather than mimicking a sound to describe something, these words describe conditions, feelings, or states.
Gitaigo is probably the most unique type of onomatopoeia in the Japanese language.
| びしょびしょ | Bisho bisho | Completely wet by a large amount of water |
| がーん | Gaan | Feeling shocked |
| べとべと | Beto beto | Feeling sticky with lots of sweat |
| ひんやり | Hinyari | Feeling cool |
| つるつる | Tsuru tsuru | Slippery |
| さらさら | Sara sara | Something feels very smooth |
| はらはら | Hara hara | Feeling anxious and worried about something |
| ぐちゃぐちゃ | Gucha gucha | Messy condition, especially used for desk or room |
WRITING JAPANESE ONOMATOPOEIA
There are no specific rules regarding onomatopoeia writing. But in most cases, Japanese onomatopoeia are written using either hiragana or katakana.
In mangas, you see both hiragana and katakana are used to write these words. So, this is another reason why learning both components is really important to understand the emotion of the Japanese language.
Some onomatopoeia have kanji as well. But you’ll rarely see them used even though they do exist. Here’s what it looks like:
| 燦燦(さんさん) | San san | Lots of sunlight |
| 昏昏(こんこん) | Kon kon | Long deep sleep |
| 齷齪(あくせく) | Akuseku | Feeling like you don’t have enough time |
| 煌煌(こうこう) | Kou kou | Bright and shining condition |
| 凸凹(でこぼこ) | Dekoboko | Uneven ground condition |
| 轟轟(ごうごう) | Gou gou | The sound of the running train |
