Japanese Adverbs: A Complete Guide

Japanese Adverbs: A Complete Guide
Japanese Grammar

Japanese adverbs play a big role in expressing yourself naturally. Adjectives describe nouns, but adverbs do much more. They add nuance, emotion and detail to verbs, adjectives and even other adverbs. Once you start noticing them, you will realize that Japanese uses adverbs everywhere.

In Japanese, adverbs are called ふく (fukushi). Some simply modify actions or descriptions, while others show things like frequency such as often or rarely, or express ideas like maybe, never or probably.

One nice thing is that Japanese adverbs almost never change their form. You learn them once and you can use them as they are.

How to Use Japanese Adverbs

Japanese word order is pretty flexible, but adverbs typically go before the word they modify. Since verbs go at the end of a sentence in Japanese, the adverb will usually appear before the verb.

Look at these two sentences. They both mean the same thing, with just a slight shift in emphasis:

よくともだちとえいきます。
Yoku tomodachi to eiga o mi ni ikimasu.
"I often go to the movies with friends."

ともだちとよくえいきます。
Tomodachi to yoku eiga o mi ni ikimasu.
"I go to the movies with friends often."

When sentences get more complex with multiple clauses, place the adverb as close as possible to the word it modifies to keep things clear:

はるがもうすぐわってますますあつくなります。
Haru ga mou sugu owatte masu masu atsuku narimasu.
"Spring will be ending soon and it'll get hotter and hotter."


Turning Adjectives into Adverbs

You can turn many Japanese adjectives into adverbs. This works a lot like English, and the rules are simple once you learn them.

i-Adjectives: い → く

Adjective Adverb Meaning
おそ おそ slow → slowly
はや はや early → early
すごい すごく amazing → amazingly
はや はや fast → quickly
わる わる bad → badly
いい よく good → well

おきなわはすごくうつくしい!
Okinawa wa sugoku utsukushii!
"Okinawa is incredibly beautiful!"

na-Adjectives: な → に

Adjective Adverb Meaning
(な) serious → seriously
しずか(な) しずかに quiet → quietly
じょう(な) じょう skillful → skillfully
(な) poor → poorly

こっせつしたくびのせいでまえいてしまいました。
Kossetsu shita tekubi no sei de namae o heta ni kaite shimaimashita.
"I wrote my name poorly because of my broken wrist."


Adverbs About Time

Time adverbs add context to when something happens. You do not always know the specific hour, but these words let you focus on what matters.

Adverb Reading Meaning
いつも itsumo always
ときどき tokidoki sometimes
よく yoku often
しばらく shibaraku for a while
ずっと zutto the entire time; always
すぐに sugu ni right away

すでに sude ni already
はじめて hajimete for the first time
また mata again

ずっといっしょにいたい!
Zutto issho ni itai!
"I want to be together forever!"

宿しゅくだいがやっとできました。
Shukudai ga yatto dekimashita.
"I finally finished my homework."


Adverbs About Frequency

How often does something happen? These adverbs tell you.

たいてい taitei usually

Adverbs About Degree

A day at the beach is not just hot, it is very hot. These adverbs add intensity and emotion.

Adverb Reading Meaning

"The book became more and more interesting."

いちばんきなものはピザです!
Ichiban suki na tabemono wa piza desu!
"My favorite food is pizza!"


Adverbs About Manner

These adverbs describe how an action is done. If you're just starting out with Japanese, you will probably ask someone to speak ゆっくり (slowly) and はっきり (clearly) quite often.

Adverb Reading Meaning
ゆっくり yukkuri slowly
はっきり hakkiri clearly
しっかり shikkari firmly, properly
きちんと kichinto neatly
なるべく narubeku as...as possible
とにかく tonikaku anyway, at any rate
せっかく sekkaku with effort; at great pains
だんだん dandan gradually
やはり・やっぱり yahari/yappari as expected

せっかくつだってくれたのに…
Sekkaku tetsudatte kureta no ni...
"Even after you went through all that trouble to help me..."

なるべくはやおくっておきます。
Narubeku hayaku okutte okimasu.
"I'll send it as soon as possible."


Adverbs About Certainty

Making guesses? Expressing confidence? These adverbs handle probability and conjecture.

Adverb Reading Meaning
ぶん tabun probably (confident)
おそらく osoraku probably (less confident)
きっと kitto surely, definitely
もちろん mochiron of course
たし tashika perhaps (based on memory)
zehi by all means

ほんてください!
Zehi nihon ni kite kudasai!
"Please come to Japan. I really mean it!"


Negative Adverbs

Some adverbs require negative verb endings. The sentence must end with ない, ません, or another negative form.

Adverb Reading Meaning
まだ〜ない mada~nai not yet
あまり〜ない amari~nai not very
ほとんど〜ない hotondo~nai hardly
ぜんぜん〜ない zenzen~nai not at all
けっして〜ない kesshite~nai absolutely not; never
べつに〜ない betsu ni~nai not particularly
めったに〜ない metta ni~nai rarely, hardly ever

さっぱりからないよ。
Sappari wakaranai yo.
"I have no idea." (Literally: I don't understand at all.)

ふゆかならずしもさむくありません。
Fuyu no hi wa kanarazu shimo samuku arimasen.
"Winter days aren't necessarily cold."

Modern Usage Note:

In casual modern Japanese, ぜんぜん is sometimes used with positive statements to mean "totally", for example 全然いい ("totally fine") or 全然大丈夫 ("completely okay"). It's informal and technically non-standard, but you'll hear it all the time.


Onomatopoeic Adverbs

Japanese onomatopoeia is way more common than in English. These words evoke vivid images and feelings, and they also function as adverbs.

Adverb Reading Meaning
にこにこ nikoniko smiling happily
くすくす kusukusu giggling
しくしく shikushiku weeping
ぺらぺら perapera fluently
ふらふら furafura dizzy, unsteady
わくわく wakuwaku excited
どきどき dokidoki heart pounding
きらきら kirakira sparkling

おんなはきらきらかがやいていた。
Onna no ko no me wa kirakira kagayaiteita.
"The girl's eyes were sparkling."

きなひとわたしとなりせきすわってむねがどきどきした!
Suki na hito ga watashi no tonari no seki ni suwatte mune ga dokidoki shita!
"The person I like sat next to me and my heart was pounding!"
