Japanese Swear Words: 25 Real Insults and Curses

🇯🇵 Japanese · 26 cards · B1 · by Haruka Sato

Japanese has no f-word. Almost nothing on this list is taboo the way English obscenities are — offence here comes from rudeness: dropping polite forms, choosing a blunt pronoun, barking a plain-form command. That is why 黙れ (damare, "shut up") lands harder than any anatomical word.

Every card gives you kanji, kana and romaji, because at the start you need all three. I have ordered them from everyday irritation (うざい, キモい) up to the ones that end friendships (死ね, くたばれ). Read the notes before you open your mouth: a few are normal between friends in Osaka and unthinkable in a Tokyo office. Mostly, learn these so you understand what you are hearing.

1バカ
Kanji 馬鹿. The default insult in Tokyo and the east. Mild — friends and couples use it playfully — but tone decides everything.
bakaidiot, stupid
もう、バカじゃないの?
Come on, are you stupid?
2アホ
Kanji 阿呆. Example is Kansai dialect. In Osaka アホ is the light, joking word and バカ is the heavy one; in Tokyo it is the other way round.
ahoidiot, fool
何言うてんの、アホやな。
What are you talking about, you idiot.
3うるさい
Kanji 煩い / 五月蝿い. Literally "noisy", but shouted at a person it means "shut up". Very common, mild to medium.
urusaishut up; noisy, annoying
うるさい!今、集中してるの。
Shut up! I'm trying to concentrate.
4うざい
Youth slang, shortened from うざったい. Constant among teens and twenties; rude but not shocking.
uzaiannoying, irritating
あいつ、マジでうざい。
That guy is seriously annoying.
5キモい
Short for 気持ち悪い; also written きもい. Aimed at a person it is genuinely hurtful — it implies physical disgust.
kimoigross, creepy
その言い方、ちょっとキモいよ。
The way you said that is kind of creepy.
6むかつく
A verb used about the thing that angers you, not shouted at a person. Originally "to feel nauseous".
mukatsukuto piss (someone) off, to be infuriating
あの態度、マジでむかつく。
That attitude really pisses me off.
7下手くそ
下手 (bad at) + くそ (shit) as an intensifier. Blunt but normal between friends or teammates; never to a customer or a senior.
hetakusoterrible at something, hopeless
運転、下手くそすぎでしょ。
You're way too bad at driving.
8黙れ
Plain-form command of 黙る. Colder and far more aggressive than うるさい — this is fight language, and masculine-sounding.
damareshut up
黙れ、お前には関係ない。
Shut up, this has nothing to do with you.
9ブス
Aimed at women. Strong and genuinely cruel. ブサイク (busaiku) is the more general word and is used for men too.
busuugly woman
人のことブスって言うな。
Don't call people ugly.
10デブ
Body insult, strong. Some people use it about themselves as a joke, but never say it to someone else.
debufatso
デブって言われて、ずっと泣いてた。
She cried for ages after being called fat.
11ハゲ
Kanji 禿げ. A classic insult thrown at middle-aged men; medium strength, often intensified as クソハゲ.
hagebaldy
ハゲって言うなよ、気にしてるんだから。
Don't call me baldy, I'm sensitive about it.
12ババア
Rough form of おばあさん, aimed at women. Strong. Male counterpart: ジジイ (jijii, "old geezer").
babaaold hag
あのババア、また文句言ってる。
That old hag is complaining again.
13クズ
Kanji 屑, literally "scraps". Attacks character rather than looks. Strong.
kuzuscum, trash (of a person)
約束破るなんて、ほんとにクズだな。
Breaking your promise like that — you really are scum.
14変態
In Japanese this is a serious accusation of sexual misconduct, not the English fandom meaning. Shouting it in public draws attention fast.
hentaipervert
近寄らないで、この変態!
Don't come near me, you pervert!
15お前
Not a swear word, but using it with a stranger, a boss or anyone older is itself an insult. Normal between close male friends.
omaeyou (rough)
お前に何がわかるんだよ。
What would you know about it?
16てめえ
Contracted from 手前; also written てめぇ. Openly aggressive and male-coded — the pronoun of a street fight or a yakuza film.
temeeyou (hostile)
てめえ、何様のつもりだ。
Who the hell do you think you are?
17貴様
Once an honorific, now pure contempt. Rare in real speech, everywhere in anime, manga and war films.
kisamayou (contemptuous)
貴様だけは絶対に許さない。
You are the one person I will never forgive.
18バカ野郎
野郎 (yarō) = "bastard, guy", directed at men. Strong, shouted in anger. クソ野郎 (kusoyarō) is harsher again.
bakayarōdamn idiot, you bastard
このバカ野郎、早く謝れ!
You damn idiot, apologize already!
19クソ
Kanji 糞. Used alone as a curse and as a prefix meaning "damn" (クソ暑い = damn hot). Vulgar but very common in casual speech.
kusoshit, damn
クソ、また負けた。
Dammit, I lost again.
20ちくしょう
Kanji 畜生, literally "beast". Frustration aimed at fate, not at a person. Slightly old-fashioned and masculine.
chikushōdamn it, dammit
ちくしょう、間に合わなかった。
Dammit, I didn't make it in time.
21クソガキ
クソ + ガキ (brat). Said about children, or about an adult behaving like one. Strong, though often half-joking.
kusogakilittle brat, damn kid
あのクソガキ、また窓割ったの?
That little brat broke the window again?
22ふざけるな
Contracts to ふざけんな or ざけんな in real speech. Strong — this is what you shout when you have been cheated.
fuzakeru nadon't screw with me, are you kidding me
ふざけるな、金返せよ。
Don't screw with me, give me my money back.
23なめるな
From 舐める, "to lick". Usually heard contracted as なめんな(よ). Aggressive, about wounded pride.
nameru nadon't underestimate me, don't disrespect me
なめるなよ、こっちは素人じゃないんだ。
Don't underestimate me, I'm no amateur.
24死ね
Two syllables, "shi-ne", not like English "shine". Very strong and tied to school bullying and online abuse. Listening vocabulary only — never say it, even as a joke.
shinedrop dead, die
死ねなんて言うのはやめなよ。
Stop telling people to drop dead.
25くたばれ
Vulgar command from くたばる (to croak, to die). Strong and a bit old-school; relationship-ending.
kutabaredrop dead, go to hell
くたばれ、二度と来るな。
Go to hell, and never come back.
26ちんこ
Vulgar anatomical slang, childish rather than hostile — unlike English, it is not thrown at people as an insult. Clinical word: 陰茎 (inkei).
chinkodick, cock
小学生の男子は、ちんこって言うだけで笑う。
Elementary school boys laugh just at the word "chinko".

Questions about this deck

Does Japanese have swear words as strong as the English f-word?
Not really. Japanese has very few taboo obscenities, and the anatomical ones like ちんこ sound childish rather than shocking. Offence comes from register: a blunt pronoun (てめえ), a plain-form command (黙れ), or dropping polite language with someone senior. A grammatically clean sentence in the wrong form can insult more than クソ does.
What is the difference between バカ and アホ?
Both mean "idiot", but the weight flips by region. In Tokyo and eastern Japan バカ is the everyday, often affectionate word and アホ sounds harsher. In Osaka and Kansai アホ is the light, joking one, while calling an Osakan バカ is a real insult.
Is 死ね (shine) as bad as it looks?
Yes. It is the plain-form command "die", pronounced "shi-ne", and in Japan it is strongly associated with school bullying and online harassment. It is not a jokey "go die" the way English speakers sometimes use it. Even among friends it kills the conversation, so keep it as listening vocabulary.
Which Japanese words for "you" are insulting?
お前 is rough but normal between close friends or from an older man to a younger one; used with a stranger or a boss it is rude. てめえ is openly hostile and signals a fight. 貴様 is contemptuous and mostly fictional today. Safest is the person's name plus さん, or simply dropping the pronoun, which is what native speakers usually do.
