Japanese Slang: ガチ (Gachi)

What is ガチ/”Gachi”? Using Japanese Slang

When you are learning a foreign language, studying slang is an easy and fun way to deepen your vocabulary. Not only will you speak more fluently but you will sound more like a native speaker. Moreover, slang gives you an interesting point of view on society. Let’s learn more about Japanese slang with the word “gachi”, “gachi de”.

A Sumo Match…?

Have you ever seen a sumo match? It is really impressive. When the rikishi (sumo wrestlers) rush into the fight, it is usually over in a second but not without a noise! On the contrary the violent clash of sumo wrestlers echoes in the arena… The Japanese onomatopoeia for that sound is “gatsun” (“crash”, “thump”).

Well, it is said that “gatsun” is the etymology for the word “gachinko” which originally meant a “serious match”, “a heated battle”, “a violent collision”. However, from the second half of 2000s, young Japanese people started to use “gachi” and “gachide” in conversation like “super” and “serious”. In short, Gachi is the short form of gachinko and is used as a prefix, often with the particle 「で」”de”.


Gachi comes to reinforce your opinion of something or to highlight a critical situation and has gained popularity among Japanese teenagers. In particular, it replaced the colloquial word maji which means “in earnest” and “seriously”.



Sentence Examples

Rei: Kono owarai konbi, gachi de omoshiroi!
Example: This comedy duo is super fun!

Rei: Daigaku no gakushoku no katsukarē tte, gachi de tsurai yo ne.
Example: The cutlet curry of our University’s cafeteria is seriously spicy!

Rei: Koko no o-ten no tanuki udon, gachi de shikotteru na.
Example: This shop’s tanu gyudon are super tasteful!


If one of your Japanese friend says that he is “on a gachi diet”, it means he is “seriously doing a diet” and “having a gachi match” means “having a battle seriously”. Of course, you should use gachi and gachi de only during conversations with people you know well.
