What Does Yabai (やばい) Mean in Japanese? A Detailed Guide

The Meaning of Yabai in Japanese やばい ヤバい ヤバイ English Translation yabee, yabe, yaba

The Japanese word yabai (やばい) caused me a lot of confusion because of its many meanings and contradictory English translations. If you look up the word “yabai” in a dictionary to see what it means, you will probably get confused, too. However, after living in Japan for many years I have finally got the hang of it. So let me explain you all meanings and possible translations of the the Japanese word yabai (やばい) in English.

The Japanese word yabai (やばい) has 4 meanings. It can mean “amazing” or “omfg” when talking about someone or describing something awesome, “awful” or “oh no” when something bad happens, “crazy” or “funny” both in a good or a bad way, and last but not least “dangerous” which is its original meaning.

The different translations and seemingly contradictory meanings are exactly what makes the Japanese word “yabai” so difficult to understand for non-native speakers. If you are still confused you can find a detailed explanation of its meaning and how to use yabai in Japanese down below. We also look at the even slangier versionsyabe” and “yaba” that you can hear a lot in daily conversations before covering some common questions such as whether you should write yabai in hiragana or katakana.

The 4 Meanings & Common English Translations of Yabai (やばい)

Since yabai (やばい) has different meanings depending on when it is used and how it is said, there is not just one English translation that is suitable and correct, but dozens. Below you can find some of the most commonly used translations that I have encountered in dictionaries, anime, manga, and daily conversations with my friends in Japan.

  • amazing, cool, impressive, awesome, wow, OMFG
  • awful, terrible, crap, oh no, oh my god
  • crazy, insane, strange, weird, funny
  • dangerous, risky, suspicious

If you know some Japanese yabai (やばい) will immediately remind you of sugoi (すごい) which has the same contradictory meanings “amazing” and “terrible” in Japanese. Both are common words, but “yabai” is more slangy than “sugoi” and in contrast to “sugoi”, all four meanings of yabai (やばい) are as frequently used. So the correct English translation really depends on the situation and intonation.

1. Yabai Meaning “Amazing”, “Cool”, “Wow”, and OMFG

Yabai (やばい) is often used as an exclamation when you see something great or when you want to describe that something or someone is awesome. It can be translated as “amazing“, “cool“, “oh my god“, “omfg“, “wow“, “awesome“, etc. When “fangirling” over your favorite anime character or singer you can also say “yabai”.

Yabai! Mecha oishii!
Wow! This is so good!

Yabai! Kawaii!
Oh my god! It’s so cute!

Sasuke-kun kakkoo ii! Yabai!
Sasuke is so cool! OMFG!

Kono anime yabai!
This anime is amazing!

Kimi no tomodachi yabai ne!
Your friend is awesome!

In this situation yabai (やばい) is usually said with a lot of enthusiasm and/or amazement. It can be used to describe or praise really anything you find awesome including people, places, things, food, (anime) character, someone’s talent, abilities, skills, etc.

2. Yabai Meaning “Awful”, “Terrible”, “Oh no”, and OMG

However, yabai (やばい) can also be used as an exclamation when you panic or something bad happens and to express that something or someone is unpleasant. It this situation it can be translated as “awful“, “terrible“, “awful“, “oops“, “crap“, “oh no“, “oh my god“, and “oh my goodness“.

Yabai! Yabai! Yabai! Shukudai wasurechatta!
Oh no! Oh no! Oh no! I forgot my homework!

Kotoshi kafunshou yabai!
My hay fever is terrible this year!

Yabai! Hashiranai to ma ni awanai!

Atsusa yabai ne!
It’s terribly hot, isn’t it!
(It’s too hot, isn’t it)

Ame wa yabai naa…
The rain is terrible…
(What’s up with this heavy rain…)

When yabai (やばい) is used to describe something bad it is usually said with outrage, indignation, shock, or disgust. It should be pretty clear from the situation and the intonation that the person is in trouble or uses the word to describe something or someone unpleasant.

3. Yabai Meaning “Crazy”, “Insane”, “Strange”, and “Funny”

Another very common way to use yabai (やばい) is when you want to talk about something “crazy”, “insane“, “weird“, “funny“, or “strange“. Similar to “crazy” in English it can be used in both a positive and a negative way – usually depending on how you say it. The slang word “sick” is another really fitting translation in this case.

Kono neko maji yabai (warai).
This cat is so funny *lol*! (positive)

Kono neko maji yabai…
This cat is so weird… (negative)

Yabai yatsu desu ne…
Yeah, he is a strange guy… (negative)

Katta! Yabai jan!
I won! Isn’t that crazy? (positive)

Tomodachi chotto yabai ne…
Your friend is a bit crazy, huh? (negative)

4. Yabai Meaning “Dangerous”, “Risky”, and “Suspicious”

The original meaning of the Japanese word yabai (やばい) is “dangerous“, “risky“, “suspicious“, etc. Since it is also sometimes used to alert or warn someone you can also think of it meaning “Look out” or “Watch out“. Some people say that the word originated from the phrase “Iya! Abunai” which means “No! It’s dangerous!

Suzume bachi yabai!
Hornets are dangerous

Yabai! Kuma da!
Watch out! A bear!

Kono monsutaa maji yabai yatsu da.
This monster is really dangerous.

Kouen ni yabai hito ga iru…
There is a suspicious person in the park…

When you look at the example sentences above you will notice that in some cases you could also translate yabai as “crazy” or “oh my god” instead of “dangerous“. The best and most fitting translation really depends on the situation.

Just think of yabai (やばい) as the Japanese counterpart of the English slang word “sick“, “sic“, or “dope“. They are notbad words” and your friends won’t consider you rude when you use any of those words in front of them.

Yabee (やべー), yabe (やべっ), and yaba (やば, やばっ) are all different versions of the Japanese word yabai (やばい). The difference is that yabee, yabe, and yaba are slangier versions most commonly used in spoken Japanese and that they sound more casual and rather masculine in comparison to yabai.

Women can use the different variations, too. However you should only use them when you want to sound tomboyish or rather masculine. Definitely don’t use them when you want to come across as “kawaii”. Sometimes you will hear young female students use them when they talk to their close female friends, but rarely when they talk to guys.
