You are eating ramen.
Normal background music is playing.
A new song starts.
An Inmu fan freezes.
“...Wait.”
Another one looks up.
“Oi, matei.”
Everyone else keeps eating.
The staff keeps working.
Then the fan realizes what is playing.
“FA!?”
Staff: “It’s just USEN.”
That is the joke.
The funniest part is not simply that an Inmu meme song is playing in a public restaurant. It is the reversal:
people who know the meme often hesitate to play it openly, while people who know nothing about it can play it with absolute confidence as ordinary background music.
1. INMU KING really did reach a mainstream chart
On ORICON’s weekly YouTube chart for September 25–October 1, 2026, “INMU KING / YAJU-MC” ranked No. 2 with 3,866,043 views.
So numerically, this is no longer a tiny video watched only by a hidden corner of Japanese internet culture.
USEN also operates a weekly J-pop ranking channel built from airplay performance, listener requests, and other data.
But an important correction: there is no verified evidence here that “ORICON No. 2 automatically caused USEN to add INMU KING.” Nor did the sources checked confirm that INMU KING itself entered USEN’s official weekly ranking.
So do not turn this into:
ORICON chart → automatic USEN selection → mandatory Inmu in every ramen shop.
That part would be speculation.
What we can say is that sightings of INMU KING playing in restaurants have appeared online, and that is enough to create the comedy.
2. Knowledge becomes a brake
An Inmu fan choosing the song in their own workplace may think:
“Will customers get this?” “Will coworkers think I selected it?” “Am I about to reveal how much Inmu lore I know?”
Knowledge creates hesitation.
A restaurant that does not know the meme has no such brake.
Shop: “Popular song? Sounds fine.”
Fan: “That is not what ‘fine’ means here.”
Shop: “Is there a problem?”
Fan: “...No.”
This is the perfect inversion:
the person with the most context is the most cautious; the person with zero context is the most fearless.
3. The restaurant gets assigned a personality it never asked for
The next step is even better.
The restaurant may have done absolutely nothing except subscribe to a background-music service.
But fans see INMU KING playing and immediately build a story:
“This shop is run by an Inmu fan.” “Yarimasu ne!” “Good place.” “I need to visit.”
The shop denies it.
“We don’t know what you mean.”
Fans answer with the classic suspicious nod:
“Ah... fūn.”
The denial does not kill the joke. It improves it.
If the owner intentionally selected the track because they are a fan, that is simple.
If the owner genuinely has no idea what the meme means, yet is broadcasting it more confidently than actual Inmu fans would, that is much funnier.
4. The audience knows more than the actor
This resembles dramatic irony.
The staff thinks: “background music.”
Ordinary customers think: “some current song.”
The Inmu fan hears: “why is this specific internet artifact playing in a public dining room?”
Same audio. Different mental worlds.
The fan has extra information.
That knowledge turns an ordinary restaurant scene into an event.
Fan: “Stop this.”
Staff: “Why?”
Fan: “Explaining why would make things worse for me.”
Checkmate.
5. It is a “benign violation”
Humor researchers Peter McGraw and Caleb Warren proposed the benign-violation theory: something can become funny when it feels both wrong or norm-breaking and harmless at the same time.
That fits this situation unusually well.
Fan brain: “This is wildly out of context.”
Reality: “Nobody is actually being harmed. People are just eating noodles.”
So the emotional sequence becomes:
“This should not be here.” → “But nothing bad is happening.” → laughter.
It is socially misplaced, yet peaceful.
6. The internet basement leaks into everyday life
Inmu culture spent years as a meme ecosystem that was easy to recognize for insiders and awkward to explain to outsiders.
Then a song based on that culture reaches a major chart.
Then the music can appear in ordinary public environments.
Two contexts that were once separate suddenly collide:
internet meme space + lunch at a ramen shop.
Media researchers use “context collapse” for situations in which audiences or social contexts that were normally separate become mixed together.
Here, the collision itself is the joke.
Fan: “We had separate habitats.”
Background music system: “Not anymore.”
7. Why “the shop does not know” is funnier than “the shop is a fan”
Imagine two versions.
Version A:
Owner: “I love Inmu. I deliberately play INMU KING.”
Logical. Expected. Joke mostly finished.
Version B:
Owner: “What is Inmu?”
Speakers: INMU KING.
Fan: “FA!?”
Now the scene has information asymmetry, accidental boldness, and social risk for the person who understands it.
That is much stronger.
8. Accidental marketing
The final layer is that the shop can gain attention without trying.
Someone posts:
“INMU KING was playing in this ramen shop lol.”
Other fans become curious.
“I want to see that.” “Yarimasu ne.” “Arigato-nasu.”
The restaurant receives visitors because of a cultural signal it may not even understand.
The owner asks:
“Why are younger customers suddenly showing up?”
The internet replies:
“ii zo~ kore.”
At that point, is it reputational damage or free promotion?
Kore mō wakannē na.
9. Conclusion
The joke is not simply “Inmu became mainstream.”
It is more precise:
Inmu fans know enough to feel embarrassed about making the meme public.
The ordinary shop knows too little to feel embarrassed.
Therefore the shop publicly broadcasts the meme with more confidence than its own fans.
That inversion is the whole thing.
Shop: “It’s just USEN.”
Fan: “Correct.”
Shop: “Seems popular.”
Fan: “Correct.”
Shop: “Nice song.”
Fan: “...Correct.”
Internal voice:
FAAAAA!?
