Top 7 Most Offensive Japanese Swear Words
Japanese is known for being a nuanced and elegant language, but like any language, it also comes with a rich vocabulary of insulting words. In this week’s WTF Japan, we go beyond the familiar Baka and explore some of the most offensive terms in Japanese. Be warned: these words are NSFW and could cause serious offense. We’ll also provide examples to help you recognize them—though we strongly advise against using them yourself.
Let’s dive in!
7. “Nasty” Words: ブス (Busu), ブタ (Buta)
While not as extreme as some of the words below, these two are still highly offensive. Busu is a blunt way to call someone “ugly,” similar to calling someone a “dog” in English. Buta (pig) is especially hurtful when targeting someone’s weight or eating habits. In Japan, where appearance and social perception matter greatly, these insults cut deep.
Example:
あのブタ、またデブってるじゃん。
Ano buta, mata debutteru jan.
“Look at that pig—getting even fatter.”
6. “Disrespectful” Words: この野郎 (Kono Yarou), 死ね (Shine)
These expressions show extreme contempt. Kono Yarou is like calling someone a “damn bastard,” while Shine (“Die!”) is a direct, vicious command. Unlike English’s “Go to hell,” Shine is chillingly straightforward.
Example:
この野郎、二度と顔を見せるな！
Kono yarou, nido to kao o miseru na!
“You bastard, don’t ever show your face again!”
5. “Stupid” Words: キチガイ (Kichigai), カス (Kasu)
Beyond Baka, Japanese has harsher ways to insult intelligence. Kasu means “trash” or “scum,” implying someone is worthless. Kichigai (“crazy”) is so offensive it’s often censored—it’s a cruel slur against mental illness.
Example:
お前の意見はただのカスだ。
Omae no iken wa tada no kasu da.
“Your opinion is pure garbage.”
4. Gender-Specific Insults: あばずれ (Abazure), やりまん (Yariman)
Some insults target women specifically. Abazure (“hussy”) is an old-school insult, while Yariman is a modern-day “slut.” For men, Do’inpo (“useless”) or Yarichin (“dickhead”) are equivalents.
Example:
あのやりまん、また男を変えてるぞ。
Ano yariman, mata otoko o kaeteru zo.
“That slut’s already onto another guy.”
3. “Drop Dead” Tier: くたばれ (Kutabare), 消えろ (Kiero)
Telling someone to Kutabare (“Drop dead!”) or Kiero (“Disappear!”) is nuclear-level hostility. These phrases are so strong they’re often bleeped in media.
Example:
くたばれ、このクズ野郎！
Kutabare, kono kuzu yarou!
“Drop dead, you piece of trash!”
2. Fighting Words: くそったれ (Kusottare), ケツメド野郎 (Ketsumedo Yarou)
Kusottare (“shithead”) and Ketsumedo Yarou (“asshole bastard”) are the kind of insults that start brawls. Use them, and expect fists to fly.
Example:
てめえ、ケツメド野郎！ぶっ殺すぞ！
Temee, ketsumedo yarou! Bukkorosu zo!
“You asshole! I’ll kill you!”
1. The Ultimate Taboo: まんこ (Manko)
The Japanese equivalent of the “C-word,” Manko is so offensive it’s almost never spoken aloud. It’s deeply sexist and can even land users in legal trouble.
Example (contextual, not direct use):
芸術だと言ってまんこをスキャンしたら逮捕された。
Geijutsu da to itte manko o sukyan shitara taiho sareta.
“They got arrested for scanning their genitals, calling it ‘art.'”
Japanese insults range from crude to downright dangerous. While knowing them helps understand media or overheard arguments, never use them lightly—some can ruin relationships (or get you punched).
