Japanese Words for Laughing and Crying: Geragera, Kusukusu, Shikushiku

English has laugh, giggle, chuckle, smirk, sob, bawl and weep. Japanese has fewer verbs and many more sound words: warau (to laugh) and naku (to cry) are combined with mimetic words that paint the sound and the face. Geragera is a loud, helpless laugh; kusukusu is a giggle you try to hide; niyaniya is a sly grin you would rather not see. Shikushiku is quiet crying, wanwan is a child's loud wailing, and poroporo is the tears themselves rolling down. These words are everywhere in conversation, manga and storytelling, and they make your Japanese sound vivid at once. This guide sorts them by feeling, explains the grammar for using them, warns about a few that carry judgement, and ends with you retelling a film to a friend.

Geragera is a loud laugh, kusukusu a hidden giggle, kerakera a light one

Nikoniko is a warm smile; niyaniya is a smirk with a hint of something sly

Shikushiku is quiet sobbing, wanwan loud bawling, poroporo falling tears

Mesomeso describes weepy self-pity and is often a criticism

Two laughs, two cries

Start with four words that cover the extremes: a loud laugh and a quiet one, a loud cry and silent tears. They are written in katakana here, as they usually are in manga and on screens; hiragana is just as common in messages.

わんわん泣くwanwan nakuto bawl loudly
涙がポロポロnamida ga poroporotears rolling down

Kinds of laughing

Each laughing word suggests a sound, a face and a feeling. Choose by asking: was it loud or quiet, open or hidden, kind or not?

JapaneseRomajiMeaning
みんなでゲラゲラ笑った。Minna de geragera waratta.We all roared with laughter.
子供たちがケラケラ笑ってる。Kodomotachi ga kerakera waratteru.The kids are laughing away.
後ろの人がクスクス笑ってた。Ushiro no hito ga kusukusu waratteta.The people behind us were giggling.
お腹がよじれるほど笑った。Onaka ga yojireru hodo waratta.I laughed so hard my sides hurt.
WordWhat it sounds and looks likeFeeling
gerageraLoud, helpless laughter, head thrown backUncontrolled fun
kerakeraLight, bright, high laughterCarefree, often children or young people
kusukusuMuffled giggle, hand over mouthTrying not to be heard
gahahaBig, booming laughHearty; a cartoon boss or uncle
fufuSoft, closed-mouth chuckleGentle, amused

Kusukusu often has a social edge: people giggling quietly may be laughing at someone. Kerakera is innocent and bright. Gahaha is mostly a manga sound and is rarely used to describe real people unless you are joking.

Smiles without sound: nikoniko and niyaniya

Two of the most common words in this family describe faces, not sounds, and they are used with suru rather than warau. Nikoniko suru is to beam, to smile happily, often for a while: a baby, a kind shop owner, a friend who just got good news. It is purely positive.

Niyaniya suru looks similar in English, to grin, but the feeling is very different. It is the grin of someone enjoying a secret, laughing at you, or thinking something they should not. A friend who saw your text from a crush might niyaniya at you. A stranger who niyaniya at you on the train is unsettling. Never use niyaniya when you mean a warm smile.

JapaneseRomajiMeaning
赤ちゃんがニコニコしてる。Akachan ga nikoniko shiteru.The baby is all smiles.
何ニヤニヤしてるの?Nani niyaniya shiteru no?What are you grinning about?
彼女はニコッと笑った。Kanojo wa nikotto waratta.She gave a quick smile.

Kinds of crying

Crying words split into how the person cries and what the tears do. Shikushiku, wanwan and oioi describe the crying; poroporo and boroboro describe the tears.

JapaneseRomajiMeaning
妹がしくしく泣いていた。Imōto ga shikushiku naite ita.My little sister was crying quietly.
子供がわんわん泣いてる。Kodomo ga wanwan naiteru.A child is bawling.
いつまでもめそめそしないで。Itsu made mo mesomeso shinaide.Stop moping around.
涙がボロボロ出てきた。Namida ga boroboro dete kita.The tears just poured out.
WordWhat it describesTypical use
shikushikuQuiet sniffling sobsCrying alone, trying to hide it
wanwan / ēn ēnLoud wailingSmall children, or adults who let go completely
oioiLoud, open wailingOlder, dramatic; often in stories
mesomesoWeepy, whimpering self-pityOften a criticism: stop whining
poroporoTears falling drop by dropMoving moments
boroboroTears pouring, big and heavyOverwhelmed by emotion

Wanwan is also how Japanese dogs bark, so wanwan naku about a person only works because naku follows. Mesomeso is the one to be careful with: it implies that the crying is excessive, so saying it to a friend who is genuinely upset can feel harsh.

Moved, teary and crying your eyes out

Some of the most useful words describe the moment before or after tears. Uruuru suru is when your eyes fill and shine. Jīn to kuru describes the warm ache of being moved, and needs no tears at all. Gōkyū, written with kanji, literally means wailing loudly, but in casual speech people use it as I cried my eyes out, especially about films and dramas.

JapaneseRomajiMeaning
目がうるうるしてきた。Me ga uruuru shite kita.My eyes started to well up.
最後の手紙、ジーンときた。Saigo no tegami, jīn to kita.The last letter really got to me.
映画館で号泣した。Eigakan de gōkyū shita.I cried my eyes out at the cinema.
泣ける映画だね。Nakeru eiga da ne.It's a real tearjerker, isn't it?

The grammar: to, suru, or straight in

Sound words behave like adverbs. With warau and naku you can put them straight before the verb, or add to: geragera warau and geragera to warau mean the same, and the version without to is more common in speech. Words that describe a state, such as nikoniko, niyaniya, mesomeso and uruuru, more often take suru and become verbs.

JapaneseRomajiMeaning
もう、ゲラゲラ。Mō, geragera.Oh, we were in stitches.
最後はポロポロ。Saigo wa poroporo.By the end, I was in tears.
PatternExampleMeaning
Sound word + warau / nakukusukusu warauto giggle
Sound word + to + verbshikushiku to nakuto sob quietly
Sound word + suruniyaniya suruto smirk
Namida ga + sound word + derunamida ga poroporo derutears roll down

In storytelling, the sound word usually carries the stress and the emotion, so say it with energy: GERAgera waratta, not a flat geragera. Japanese listeners often repeat the sound word back to you, geragera?, as a way of showing they are following.

You can also use the sound words without a verb at all in casual speech, especially in reply to a question: dō datta? mō, geragera. How was it? Oh, we were in stitches. This clipped style is very natural with friends and sounds lively.

Scenario: retelling a film to a friend

You saw a comedy-drama last night and your friend Aoi asks how it was. Good storytelling in Japanese often uses sound words to replay the audience's reactions as well as the plot.

Two friends walking along a quiet evening street lined with trees and lanterns, one acting out a laughing scene with big gestures while the other laughs along.
Sound words replay the scene: who laughed, who cried, and how.
JapaneseRomajiMeaning
昨日の映画、どうだった?Kinō no eiga, dō datta?Aoi: How was the film yesterday?
最初はみんなゲラゲラ笑ってたよ。Saisho wa minna geragera waratteta yo.You: At first everyone was roaring with laughter.
でも最後は涙がポロポロ出てきて。Demo saigo wa namida ga poroporo dete kite.You: But at the end my tears just kept falling.
隣の人も号泣してた。Tonari no hito mo gōkyū shiteta.You: The person next to me was sobbing too.
へえ、泣ける映画なんだ。Hē, nakeru eiga na n da.Aoi: Oh, so it's a tearjerker.
うん、ジーンときた。Un, jīn to kita.You: Yeah, it really got to me.

Common mistakes

  • Using niyaniya for a friendly smile: it suggests something sly. Say nikoniko.
  • Using geragera in a polite story about your boss laughing: it can sound like he lost control. Try ōgoe de warau, to laugh loudly.
  • Saying mesomeso to comfort someone: it criticises them. Say daijōbu? instead.
  • Forgetting that shikushiku is also a dull pain: onaka ga shikushiku itai is a stomach ache, not a sad tummy.
  • Adding warau after nikoniko: nikoniko suru is the natural verb.
Key points

A practical way to improve

These words only stick when you use them to tell stories. First, pick a funny moment and a sad moment from your own week and describe each in two sentences, using one laughing word and one crying word. Second, retell the ending of a film you love in Japanese, using at least one of poroporo, gōkyū or jīn to kita. Third, in Unihongo's immersive 3D classroom, ask your AI Sensei to play a friend who has not seen the film, and tell the story while the Sensei asks questions; ask the Sensei to speak more slowly if the questions come too fast. Afterwards, check the session report for corrections to your particles, especially whether you used suru with nikoniko and niyaniya, and warau or naku with the other sound words.

FAQ

Frequently asked questions

What does geragera mean in Japanese?

Geragera (ゲラゲラ) describes loud, unrestrained laughter, like roaring or howling with laughter. It is used with warau, to laugh: geragera waratta. It suggests the person could not hold it in and did not care who heard.

What is the difference between nikoniko and niyaniya?

Nikoniko (ニコニコ) is a warm, happy smile, often a cheerful face over time, such as a baby smiling. Niyaniya (ニヤニヤ) is a grin or smirk with something hidden behind it: amusement at someone, a private joke or a slightly creepy look. Calling someone's smile niyaniya is not a compliment.

How do you say to cry a lot in Japanese?

Gōkyū suru (号泣する) means to cry hard or sob uncontrollably, and people use it casually about films: eiga de gōkyū shita, I cried my eyes out at the movie. For a child crying loudly, wanwan naku is common.

What does shikushiku mean?

Shikushiku (しくしく) describes quiet, sniffling crying, the kind someone tries to keep to themselves: shikushiku naku. The same word also describes a dull, continuous pain, such as a stomach that aches shikushiku, so context tells you which meaning is meant.
