Japanese Onomatopoeia: ぴかぴか, どきどき, and More -- Japanese Study Guide -- SimpleLits

語 (giongo) for actual sounds and 擬態語 (gitaigo) for states and sensations, are an essential part of everyday conversation, manga, anime, and literature. Mastering them will make your Japanese sound much more natural and expressive.

擬音語 (Giongo): Words for Actual Sounds

These words mimic real, audible sounds made by people, animals, objects, or nature.

わんわん wan wan woof woof (dog barking)

にゃー nyā meow

ざあざあ zā zā sound of heavy rain pouring

ぺちゃくちゃ pecha kucha chattering, gossiping

ごろごろ goro goro thunder rumbling, purring (cat)

ぱちぱち pachi pachi clapping, crackling (fire)

Many giongo are repeated twice (e.g., わんわん, ざあざあ) to indicate a continuous or repetitive sound.

擬態語 (Gitaigo): Words for States and Sensations

These words describe conditions, feelings, or manners—things that don’t actually make a sound.

ぴかぴか pika pika sparkling, shiny

じめじめ jime jime damp, humid, gloomy

ふわふわ fuwa fuwa fluffy, soft, light

pera pera fluent (in a language), thin (paper/object)

さくさく saku saku crispy, crunching (e.g., walking on dry leaves)

Words for Emotions and Feelings

Some onomatopoeia are especially useful for describing internal states and emotions.

どきどき doki doki heart-pounding (nervous or excited)

わくわく waku waku excited, thrilled

いらいら ira ira irritated, frustrated

がっかり gakkari disappointed, let down

うっかり ukkari carelessly, unintentionally

ほっと hotto relieved

Many emotion words like どきどき and わくわく are often used with する (suru) to mean "to feel [that way]." For example: どきどきする (doki doki suru) — "to feel nervous/excited."

Body Feelings and Physical Sensations

You can also describe how your body feels using onomatopoeia.

ずきずき zuki zuki throbbing pain

くたくた kuta kata exhausted, worn out

ぽかぽか poka poka warm and cozy

ぞくぞく zoku zoku shivering (from cold or excitement)

むかむか muka muka nauseous, sick to one’s stomach

How Onomatopoeia Are Used in Sentences

Onomatopoeia are very flexible and can be used as adverbs, adjectives (with な or の), or verbs (with する).

As Adverbs (with と)

雨がざあざあと降っている。 Ame ga zā zā to futte iru. The rain is pouring down.

As な-Adjectives

ぴかぴかな車 pika pika na kuruma a shiny car

With する (to Feel/Be)
