Japanese Onomatopoeia – A Guide to Interesting Word Sounds

Japanese onomatopoeia doesn’t really get the shine it deserves at the textbook level. When learning Japanese, so much time is spent focusing on grammar and vocabulary that there’s just no thought of these sound words.

But that’s cool because this article is completely dedicated to Japanese onomatopoeia and how you can use them to make your Japanese language skills one hundred times stronger!

What’s the meaning of onomatopoeia?

An onomatopoeia is a process of naming a thing or action using a vocal imitation. Usually, the imitation sound used will be associated with the thing in some way, the same way “woof” is an English onomatopoeia of a dog barking, or “meow meow” for a cat’s sound. That’s the actual representation of the sound or sound effects we hear.

You’ll mostly come across Japanese onomatopoeia as what is used to describe sound effects as if you are reading manga. However, in a broader sense, an onomatopoeia can be any word that is used to represent a sense of some kind. Some words, like in Japanese, do not describe actual animal sounds, nature, emotional feelings, or movements.

You’ll better understand this once you’ve learned the five classifications of Japanese onomatopoeia, which we’ll go over below!

How do you say “Onomatopoeia” in Japanese?

The word onomatopoeia in Japan is ぎせいご (onomatope | 擬声語). This actually means the same thing as the English word “onomatopoeia.”

It’s hard to spell, right? That is because it originates from Greek. “Onomatopoeia” is formed by combining two Greek words that mean “sound” and “I.” It essentially means “the sounds I make.” It doesn’t get any more straightforward than that!

Understanding Japanese Onomatopoeia

You may ask yourself, “Well, how many Japanese onomatopoeiae are there anyway?” The reality may surprise you; there are over one thousand Japanese onomatopoeic expressions! That’s three times more than in English!

That’s a somewhat refreshing fact, as Japanese has a reputation for being quite a vague and under-descriptive language. The overt use of this sound symbolism and words perfectly adds color and visuals to an otherwise gray language. These words have made their mark on the Japanese language, and we’ll discover in exactly which ways as we continue along.

Classification of Japanese Onomatopoeia

Unlike English, Japanese onomatopoeia words can be broken down and classified into different categories. Each category describes sounds of a specific quality or mimetic sound.

Below are the five different kinds of onomatopoeia words in Japanese.

Giongo (ぎおんご | 擬音 語)

Technically, giongo is the umbrella term for all true onomatopoeia words in Japanese. The character “擬” (gi | ぎ) in “擬音語” means to mimic or imitate. The last two characters mean “sound” and “language,” respectively.

Giongo, when specified, are mimic sounds made by non-living or inanimate objects, including sounds in nature.



JapaneseEnglish (Meaning)
ぱらぱら (para para)The sound of raining lightly with small droplets
ごろごろ (goro goro)Tunder rumbling or rolling (of something large and heavy)
ひゅー・ぴゅー (pyuu pyuu)Onomatopoeia for the wind blowing


JapaneseEnglish (Meaning)
カリカリ (kari kari)Eating something crunchy


JapaneseEnglish (Meaning)
ピンポン (pin poon)Doorbell or bell sounds such as "ding dong! or ding ding!"
JapaneseEnglish (Meaning)
かたかた (kata kata) Clattering or typing
たたたた (tata tata)Onomatopoeia for running fast

Giseigo (ぎせいご | 擬声語 )

These onomatopoeia words represent sounds made by living things, like dogs barking or waitresses laughing. It refers to both Japanese animal sounds and human sounds.



Humans also make a lot of different noises. Here are some of them.

JapaneseEnglish (Meaning)
すーすー (suu suu)Peaceful breathing while asleep
おいおい泣く (oioi)To wail or cry loudly
きゃっ きゃっ (kya kya)Children playing and having fun


Listed below are sound effects produced by animals in Japanese, such as the “oink oink” of a pig or the “meow” of a cat.

JapaneseEnglish (Meaning)
にゃあにゃあ (nyaa nyaa)Meow/cat
ぶーぶー (buu buu)Oink/pig
げろげろ (kero kero) ribbit/frogRibbit/frog

Gitaigo (ぎたいご | 擬態語 )

Gitaigo words reflect a condition or state. These words don’t mimic actual sounds but rather describe feelings (emotional). They are also referred to as ideophones or mimetic words. You’ll mostly see this in manga.

Its sound patterns were constructed to be similar to giongo patterns. Actually, the 態 (tai |たい) in 擬態語 means appearance or condition.

This kind of onomatopoeia really makes Japanese onomatopoeic expressions so colorful – we don’t have such onomatopoeia in English. Also, some Japanese onomatopoeia words have qualities of both gitaigo and giongo.

For example, a word may have the same pronunciation but can be used in 2 different ways depending on the application. It’s pretty cool.

These three categories of onomatopoeia are the most important and most commonly taught to any Japanese language learner (including Japanese natives).

To summarize, giseigo and gitaigo are words that express sounds, whereas gitaigo expresses feelings/conditions.


JapaneseEnglish (Meaning)
ぴかぴか (pika pika)To describe what is shiny or sparkling or with glitter
むしむし (mushi mushi)Too humid or hot

2 Types of Gitaigo Onomatopoeia

For further subdivision, there are two types of Japanese onomatopoeia under gitaigo:

Gijougo (ぎじょうご | 擬情語 ) – these are words used to describe feelings.


JapaneseEnglish (Meaning)
わくわく (waku waku)The sound when you feel excited from anticipation, pleasure, or happiness
こぺこ (peko peko)Feeling hungry or the sound of a grumbling stomach

Giyougo (ぎようご | 擬容語) – these onomatopoeia words describe motions and movements.


JapaneseEnglish (Meaning)
じろっと (jirotto)Giving an accusing look. Occasionally, this is due to anger or an uncomfortable feeling
のっそり (nossori)To move slowly or sluggishly

When you learn Japanese, onomatopoeia is used as/in place of verbs quite frequently. You may hear someone say, おれはぐっすりねむりました (ore ha gussuri nemurimashita | 俺はぐっすり眠りました). The ぐっすり (gussuri) here is an onomatopoeia that refers to falling into a deep sleep.

Gitaigo, gijougo, and giyougo are all known as ideophones. These kinds of words represent something that has no actual sound of its own. It’s a different application of onomatopoeia than probably most languages, so take your time getting used to the unique patterns.

If you know your kanji, remembering which term reflects which kind of onomatopoeia isn’t so difficult. Each type of onomatopoeia is written using the same first and third kanji characters – only the middle character is different.

Here are the meanings of each middle character to make memorizing the significance a bit easier:

JapaneseEnglish (Meaning)
音 (on |おん)Sound or noise
態 (tai |たい)Condition or appearance
声 (sei |せい)Voice. Think of the voice of living things.
情 (jou | じょう)Emotions or feelings
容 (you | よう)Form

How to recognize Japanese Onomatopoeia

All onomatopoeia words in Japanese come in one of four forms. Here are the four main grammatical forms that you should know:

Double Form

The first form is the double form, where the onomatopoeia is a repetition of one or more characters. いらいら (iraira) is one example of this double form.

Onomatopoeia in this form is usually used as adjectives, but sometimes they are used as adverbs too. It’s the most common form you’ll see for onomatopoeia words in Japanese.

Ri (り) Form

Next is the ~り form, where the word ends in the character り(ri). This is an adverbial form of onomatopoeia. This form usually conveys a feeling of smoothness or softness.

Tto (と) Form

The third is the ~っと form, where the word ends in the character っと(tto). Also, mostly an adverbial form of onomatopoeia. Such words refer to things that stop suddenly and abruptly. It’s quite the opposite of the previous ~り form.

An Important Note: Although the rules of Japanese state that all words must end in a syllabic vowel (aside from ん), sometimes onomatopoeia end in っ (tsu) alone. This is to create an effect known as a glottal stop – it’s a sudden stop. Basically, the と (to) gets omitted to create a more dramatic effect. You see this all the time, especially in manga or films.

N (ん) Form

Lastly is the ~ん form, where the word ends in the character ん (n). This form is always used as an adverb right before a verb. It concludes with a nasal gulp when describing a sound, which creates an additional reverberating presence. It becomes a descriptor of continuous action when used as an adverb.

Technically, onomatopoeia words can change their form ending depending on the situation, but that rarely happens. When studying onomatopoeia, just focus on remembering the most popular form and leave it at that.

There are also plenty of non-onomatopoeia words that end in these patterns, too. Get acquainted with the grammatical structure of Japanese onomatopoeia words, and always double-check in the dictionary if you are unsure!

Hiragana Onomatopoeia vs. Katakana Onomatopoeia

There are no hard rules as to when to use (hiragana) or (katakana) for onomatopoeia. That being said, hiragana is usually used more for soft sounds, while katakana is used for harder, emphatic sounds. Perhaps the cause for this relates to the general look and feel of the two scripts – hiragana being more smooth and rounded and katakana more rigid and pertinent.

It’s not so important in the end, so don’t be surprised to see either or. Some onomatopoeia also have kanji, an example is 燦燦 (brilliant, shining sunlight), but you’ll almost never see them used.

How sounds influence Japanese onomatopoeia

That’s right. The sounds of Japanese characters themselves influence the meaning of different onomatopoeia. Aside from that, sometimes onomatopoeia words are grouped or paired together to create some coherency between them and the sound they share. Let’s start by considering the idea of sound as human beings perceive it.

There have been countless experiments conducted concerning our perception of sound and its relation to texture, shape, size, color, etc. The Kiki Bouba test is one of the most well-known of these tests nowadays. Whether the science holds true on every occasion or not, the Japanese seem to have recognized this association to some degree.

Here is some popular Japanese onomatopoeia. Can you guess which definition is correct?

ぱりぱり (pari pari)Soft and round or hard and stiff?
つるつる (tsuru tsuru)Slippery or firmly in place?
かんかん (kan kan)Heavy rain or bright sunshine?
ぱらぱら (parapara)Light rain or wind blowing leaves?
わくわく(waku waku)Excitement or boredom?

Odds are, you got most of those correct. It’s a small example of how sound can be more than just sound and how we can intuitively pick up on that. Cool.

Japanese Consonants Sound

Furthermore, subtle variations are made in Japanese onomatopoeia words to create subtly different qualities of sounds. The Japanese language consists of voiced and unvoiced consonants without going into it too deeply.

The voiced consonants are “unmanipulated” consonants and are typically associated with a stronger overall presence. Unvoiced consonants are less “pure” and have less presence.

Take a look at our article on Japanese consonants for all the details. Anyway, utilizing voiced and unvoiced consonants together is a nifty way to create easy-to-understand pairs of onomatopoeia and will help you speak fluently.

Here are some examples:

さら さら (sara sara)Silky
ざら ざら (zara zara)Rough
とん とん (ton ton)Tapping
どん どん (don don)Beating/drumming
はら はら (hara hara)Fluttering
ばら ばら (barabara)Clattering

Finally, consonants themselves affect the meaning of an onomatopoeia, just like whether or not they’re voiced or unvoiced:

ぐら ぐら (gura gura)Wobble or shake
げらげら (gera gera)Guffaw or haw-haw

For this example, both words represent a sense of rumbling surfacing of a tremor.

ぐらぐら(guragura) refers to the more violent shaking of an object, like a building during an earthquake. げらげら(geragera) is the rumbling laughter of a human being.

The two consonants here are almost the same but different enough to distinguish the meaning of onomatopoeia.

How to use onomatopoeia in Japanese

Of course, like any other part of the Japanese language, onomatopoeia must be used in tandem with proper grammar. Below, we show the rule for the grammar point and what the onomatopoeia is treated as in the sentence.

Some words are more flexible in grammar, while others are quite strict (there are thousands of these things). Practice and exposure will be your best teacher in the long run, so don’t stick to any hard rules until you’ve mastered a pattern.

Direct Quotation + と

When you want to directly quote a sound in Japanese, you can add と(to) after the onomatopoeia. This is a grammatical rule that can be used in a myriad of scenarios, including this one.


花火を見て思わず「ウワー!」呼んできた! (hanabi wo mite omowazu uwaa to yondekita!)

She saw the fireworks and screamed “wow!” without thinking! 

Adjective + の

For adjectives, simply add (no) after the word before directly adding the noun.

昨日の夜ざあざあの雨が突然に降っていた (kinou no yoru zaazaa no ame ga totsuzen ni futteita)

Last night, pouring rain suddenly began coming down.

空のふわふわの雲を見つめた (sora no fuwafuwa no kumo o mitsumeta)

We stared at the fluffy cloud in the sky.

Adverb + に/と

Remember, adverbs can be used with any verb so long as it makes sense. Some use the particle に(ni) while others may use と(to).

乗り物はぐるぐるに回っている (norimono ha guruguru ni mawatteiru)

The ride keeps spinning around and around.

お父さんは毎日仕事で頑張るので服はボロボロになってしまいました。(otousan ha mainichi shigoto de ganbaru node fuku ha boroboro ni natteshimaimashita)

Dad really works hard every day at work, so his clothes are becoming worn out.

雷がごろごろと鳴り始めました (kaminari ga gorogoro to narihajimemashita)

The thunder began to ring.

えりかさんは日本語をすらすらと読めるよね (erika san ha nihongo wo surasura to yomeru yone)

Erika can read Japanese effortlessly, you know.

Onomatopoeia + Be

The verb です(desu) means “to be” in Japanese. The short form of this verb is だ (da). When used with onomatopoeia, they function as a copula or connecting words between the subject and compliment. The verb always comes at the end of the sentence and right after the onomatopoeia.

サツマイモはもううんざりだぜ! (satsumaimo ha mou unzari daze!)

I’m already sick of sweet potatoes!

買った古着屋からマフラーはどっさりだ。(katta furugiya kara mafuraa wa dossarida)

I bought a lot of scarves from the second-hand shop.
