Bakushou (爆笑) literally translates to ‘explosive laughter.’ While learners often use it to mean ‘LOL’ or ‘hilarious,’ in Japanese, it traditionally refers to a large group of people laughing simultaneously. Understanding this distinction is key to sounding like a natural.
When I first arrived in Tokyo, I made the classic mistake of telling a friend at a local izakaya that their joke was ‘Bakushou!’ The table went silent, not because the joke wasn’t funny, but because the word felt fundamentally disconnected from the intimate setting of two people sharing a laugh. In Japanese, bakushou carries a sense of scale. It’s the roar of an audience at a manzai (stand-up comedy) show or the collective eruption of a crowded classroom.
The Linguistic Evolution: Why Definitions Don’t Always Match Reality
If you check a dictionary, it will tell you bakushou means ‘burst of laughter.’ However, the cultural usage has been shifting. Younger generations have begun using it much like the English ‘LOL’ or ‘ROFL,’ stripping away the requirement for a crowd. If you use it in a casual LINE message, you’ll be understood, but if you use it in a formal setting to describe a funny moment, you might sound like you’re over-dramatizing the situation. It’s a classic case where the Teinei (politeness) factor dictates your word choice.
Local Friend: “The comedian on TV tonight was amazing. The whole studio audience was in bakushou!”
You: “I see. So it’s not just a small chuckle?”
Local Friend: “Exactly. It’s the sound of a hundred people laughing at once. That’s the real power of the word.”
Common Mistakes Foreigners Make
The most common error is applying bakushou to a simple smile or a polite giggle. If someone tells you a cute story and you respond with “Bakushou!”, it creates a bizarre contrast. It’s like saying, “That story was a nuclear explosion of humor” in response to someone telling you their cat tripped. Keep your intensity levels matched to the situation, much like you would learn to navigate O-jama Shimashita when entering a home; context is everything.
Slang Variations and Tone
In the digital age, you might see bakushou abbreviated or replaced by internet slang like ‘草’ (kusa, meaning grass), which evolved from the ‘wwww’ (the ‘w’ stands for warai, meaning laugh) looking like blades of grass. If you want to be hip, kusa has largely replaced bakushou for digital humor.

Ultimately, becoming fluent in Japan isn’t just about the words; it’s about the scale of the emotion behind them. Use bakushou when the room is shaking, and you’ll find you fit right in.
