Kucha-kucha (クチャクチャ) is a Japanese onomatopoeia that mimics the sound of chewing food with an open mouth. In Japan, this sound is widely regarded as unpleasant and is considered a breach of table etiquette.
When someone chews audibly, particularly with their mouth slightly open, the repetitive squelching or smacking sound is represented by this term. Unlike many other Japanese onomatopoeic words that are fun or descriptive, kucha-kucha carries a negative connotation.
“A: Did you hear the person next to us? They were eating so loudly.
B: Yes, the kucha-kucha sound was quite distracting!”
In Japanese culture, eating quietly is a sign of respect for others at the table. While slurping noodles (like ramen) is perfectly acceptable and even encouraged, chewing solid food audibly is frowned upon.
Pro-Tips for Dining in Japan:
- Be mindful: Try to keep your lips closed while chewing solid food to avoid creating this sound.
- Slurping is okay: Remember that slurping noodles is considered a compliment to the chef, which is a major exception to general noise-making rules.
- Context matters: If you are looking to refine your cultural etiquette, check out our guide on O-jama shimashita to understand how to act when visiting a Japanese home, or learn about the importance of manners by reviewing Omoyari, the heart of empathy.
