Japanese Swear Words: Ranked Strongest to Weakest

Japan is renowned for its politeness, discipline, and deep respect for others, but that doesn’t mean the Japanese can’t curse. Swearing in Japanese tends to be more subtle and indirect compared to Western cultures, relying heavily on tone, context, and clever wordplay. However, when emotions run high, Japanese profanity can deliver a sharp sting. Here’s your definitive guide to Japanese swear words, ranked from strongest to weakest.

The Strongest Swear Words in Japan

1. Kuso Yarou

The Aggressive Insult

“Kuso yarou,” meaning “f***ing bastard” or “shitty idiot,” is one of the harshest things you can say in Japanese. It’s direct, insulting, and guaranteed to make an impact in an argument.

Example:
- “Kuso yarou! Ore no mae kara kiero!” (You f***ing bastard! Get out of my sight!)
- “Kuso yarou, nani wo shiteiru da?” (What the hell are you doing, you idiot?)
Pro Tip: Avoid using this unless you’re ready to seriously escalate the situation.

2. Shine

The Ultimate Threat

“Shine,” meaning “die,” is an extremely offensive and aggressive command to tell someone to “go die.” It’s not used lightly and is considered one of the most severe phrases in Japanese.

Example:
- “Shine! Mou gaman dekinai!” (Die! I can’t take this anymore!)
Pro Tip: This phrase is extremely strong—use with caution as it’s highly offensive.

3. Kisama

The Hostile “You”

“Kisama” is an old-fashioned, ultra-rude way of saying “you.” While it doesn’t sound like a swear word on its own, it carries strong contempt and disrespect.

Example:
- “Kisama wa baka ka?” (Are you an idiot, you fool?)
- “Kisama nante shinji rareru ka!” (Why would I ever trust someone like you?)
Pro Tip: Paired with an angry tone, it can be as cutting as a curse.

Mid-Tier Japanese Insults (Still Pack a Punch)

4. Baka

The Classic Insult

“Baka,” meaning “idiot” or “fool,” is one of the most common and widely recognized Japanese insults. It can range from playful teasing to outright mockery.

Example:
- “Baka ka? Kore wa machigatteiru.” (Are you stupid? This is wrong.)
- “Mou baka mitai.” (You’re so stupid.)
Pro Tip: Tone matters—say it with a smile, and it’s playful; with a glare, it’s hurtful.

5. Kuso

The All-Purpose “Shit”

“Kuso,” meaning “shit,” is a versatile swear word used to express frustration or anger. It’s often said under someone’s breath when things go wrong.

Example:
- “Kuso! Mata shippai shita.” (Shit! I messed up again.)
- “Kuso, kono kuruma wa ugokanai!” (Shit, this car won’t move!)
Pro Tip: Add it to phrases for more intensity, like “kuso yarou” (shitty bastard).

6. Busu

The Cutting Insult

“Busu,” meaning “ugly” (typically aimed at women), is a sharp insult that’s often used cruelly. It’s considered highly offensive and should be avoided unless you’re deliberately trying to insult someone.

Example:
- “Busu wa shaberu na.” (Shut up, you ugly thing.)
Pro Tip: Use at your peril—this one hits below the belt.

The Playful and Milder Swears

7. Chikushou

The Frustrated Exclamation

“Chikushou” means “damn it” or “beast” and is commonly used to vent frustration. It’s mild enough for casual use but still packs emotional weight.

Example:
- “Chikushou! Kono pasokon wa dame da!” (Damn it! This computer is useless!)
- “Ah, chikushou, muri da!” (Damn it, it’s impossible!)

8. Uzai

The Annoyance Swear

“Uzai,” meaning “annoying” or “irritating,” is a go-to word for when someone is getting on your nerves.

Example:
- “Uzai! Chotto damatte.” (You’re annoying! Be quiet.)
- “Ano hito wa hontou ni uzai.” (That person is really annoying.)
Pro Tip: It’s not overly harsh and can even be playful among friends.

9. Yabai

The Versatile Word

“Yabai” originally meant “dangerous” but has evolved into a catch-all term for expressing anything extreme—good or bad. It’s often used in a lighthearted way.

Example:
- “Yabai! Osoi!” (Damn! I’m late!)
- “Yabai, sugoi umai.” (Wow, this is ridiculously delicious.)
Pro Tip: Its mildness makes it suitable for casual settings.

10. Hen na

The Polite Oddball

“Hen na,” meaning “weird” or “strange,” is a gentle jab often used for teasing or commenting on someone’s odd behavior.

Example:
- “Hen na koto wo suru na!” (Don’t do weird things!)
- “Kimi wa hen da ne.” (You’re weird, aren’t you?)

Honorable Mentions

Bakayaro: “You idiot!” (Harsher than just “baka.”)
Orokamono: “Foolish person.”
Damare: “Shut up.”

Swearing Pro Tips

Context Is Everything: Japanese swearing relies heavily on tone and situation—what’s mild in one setting can feel harsh in another.
Respect Matters: Swearing at elders or authority figures is considered highly disrespectful in Japanese culture.
Add Emphasis with Tone: Unlike English, Japanese swearing often depends more on how you say it than the word itself.

Bonus Word: “Komorebi”

Not a swear word, but quintessentially Japanese, “komorebi” refers to the sunlight filtering through the leaves of trees. It’s a poetic reminder of the beauty in life’s small moments.

Example:
- “Kono koen no komorebi wa utsukushii.” (The sunlight through the trees in this park is beautiful.)

Conclusion

Japanese swearing may be less direct than in other cultures, but it’s no less powerful. From the biting sharpness of “kuso yarou” to the playful annoyance of “uzai,” these words capture the intricacy and subtlety of Japanese expression. Use them wisely, and remember: in Japan, it’s often how you say it that counts. Ganbatte!
