The Best Japanese Swear Words

Now, we can break down some rude Japanese words and phrases. We will look at their literal translation and some context for when to use them.

Remember, when using crass words in Japanese in real-life situations, you need to remember that the culture is different than in your country. You might think you are joking around but cause real offense. Proceed with caution.


  • Kuso (くそ) - Shit/ f*ck
    This swear word roughly translates as "poo", but it is very rude and often used as an exclamation of anger. The closest translation in English would be bad words like "f*ck" or "shit"

Screw You/ Go Away

  • Kuso kurae (くそ くら え) - Eat shit
  • Fuzakeru na (ふざけるな) - F*ck off
    This phrase literally translates as “don't mess around”. However, when it is used aggressively, it essentially has the same meaning as "f*ck off" and is pretty strong.
  • Shinjimae (しんじまえ) - Go to hell
    Another rude way to tell someone to go away is to tell them to go to hell.


  • Chikusho (ちくしょう) - Damn it/ son of a b*tch/ oh crap!
    This word is not directed at someone, but instead, it is used as a way to exclaim in frustration or dismay.
    For example, you might hear someone on the side of the road in Japan shout chikushou, panku da (ちくしょう、パンクだ), meaning "damn it! I have a flat tire".
    However, this word can also be used when something really great happens. For example, when your favorite sports team wins a match. Of course, context and tone are everything here.

Stupid/ Fool

  • Baka (ばか) - Stupid
    This word is commonly used in the Kanto region of Japan, where Tokyo is located. So, when visiting Tokyo, you might hear the locals using baka with their friends.
  • Aho (アホ) - Moron/ idiot
    This swear word, meaning "idiot", is similar to baka. The difference is that aho is more commonly used in the Kansai region of the country.

Bastard/ Asshole

  • Yarou (や ろう) - Guy
    On its own, this word means "guy" and does not have a particularly negative connotation. However, when paired with baka, meaning "stupid", it becomes a Japanese swear word.
  • Bakayarou (ばか や ろう) - Stupid bastard/ total idiot
    Baka and yarou come together here to create a very crass word in Japanese.
  • Damare konoyarou (だまれこのやろう) - Shut up, you bastard/ shut your mouth!
    When you see yarou (や ろう) added to insults, you can assume someone is being called a "bastard", "asshole", or something similar. Do not use yarou when speaking to a woman, as this is not correct.


  • Busu (ブス) - Extremely ugly woman
    This rude word is a very demeaning term that should not be used lightly.
  • Buotoko (ブ男) - Extremely ugly man
    This is the male version of the same insult. You should never call a stranger in Japan "ugly" and only use this word with friends if you are very close and can joke in this way. Or else, if you really want to cause offense!

More Japanese Insults

  • Uzai (う ざ い) - Annoying
    This word translates as "annoying" or "pain in the ass". It is short for urusai (うるさい), which means "noisy".
    So, you can also use uzai to mean "shut up", as in "you're being so noisy, can't you shut up?!"
  • Warugaki (わる が き) - Brat
    You can use warugaki with someone younger than you who is annoying you. That is, if you mean to cause some offense. This word comes in handy when a kid is being noisy, acting spoilt, or bothering you endlessly.
  • Shinee (死ねえ) - Die!/ Drop dead!
    The word shinee is commonly used in anime, so learners might be familiar with it. However, just because it is used in anime, does not mean it is appropriate. Do not tell a Japanese person to die unless you are prepared to ruffle some serious feathers!

A Note on Japanese Culture

Now that you have learned a handful of useful and interesting Japanese curses, you can start to think about when you might use this language in real life. There is just one fun fact to be aware of before you get started!

In Japan, there is a certain social hierarchy and etiquette that you need to learn for social and professional situations. This social hierarchy dictates how formally or informally you are expected to speak.

Depending on who you are with and what their hierarchical position is compared with yours, you will need to address them accordingly.

If you find yourself in a situation where nobody in the vicinity speaks English and you need to use your Japanese language skills to get by, you will need to ensure that you are using the appropriate level of politeness when addressing people.

General rules include respecting your elders and respecting your professional seniors, but there is more to it than that. So, do your homework and make sure to use crass language only with people you can be very informal with.

When in doubt, it is always best to leave out the curses and insults!
