The story
Morning Musume’s Satō Masaki (Ma-chan) revealed on her radio show that rumors spread last year claiming her tour logo was “made by AI,” and that when she pressed the creator about it, she was handed roughly 700 hours’ worth of footage documenting the production process as proof. On 5ch’s Hello! Project board, posters expressed shock that the accused party had to go to such lengths just to prove their innocence, while discussion continued comparing candidate images — the rose logo and what looks like Vesper’s umbrella logo. Meanwhile, the comments section spiraled into a generational clash over the merits of generative AI, often drifting far from the original topic of Satō Masaki herself.
What people said
So the question was, "What kind of preparations are you doing for the tour?"
Right now I think it's mostly about working hard on the logo — listen to this, apparently people were saying it was made by AI
If someone came at me out of nowhere with "Oh, so it's AI?!" based purely on rumor, I'd flip out and never work with them again.
They probably keep work-in-progress footage on hand just in case.
Pure self-defense.
Yesterday's episode had weirdly high energy.
From the way she talks about it, Satō probably had an acquaintance of hers make the logo.
Is this the rose logo?
Doesn't really look AI-made though
The other person probably understands Ma-chan's personality well
Judging by how she talks about them, maybe they're around the same age
The person who told her "people are saying it's AI" → agency staff?
Does making a logo really take that long?
Also, Ange le Vanille's "Vanilla" cover art and plenty of others look way more like that.
Satō's tour rose logo? If they actually used generative AI for something that simple, it's even more ridiculous — they should just quit the job.

Oh, the one on the left
This one does look pretty AI-generated
Even I'd be suspicious of this
I get why drawing stuff like this would be fun
If this is hand-drawn, that's impressive
The steampunk-ish umbrella logo from Vesper.
Better to ask and make sure.
I'm talking about the kind of people who, even when you post a time-lapse as proof, still refuse to accept it and keep insisting "it's AI, it's AI."
Or is it just an unskilled human being sloppy?
Hard to tell.
"This media is likely original and was not generated by AI."
No wait, Ma-chan uses AI too
Karin-chan also has a close friend who draws illustrations for her, right?
It's "looks good but is actually bad."
So it's probably human.
Is it actually normal for creators to record themselves working?
Just look at social media for a second
Where are the teens and 20-somethings happily slapping generative AI illustrations around like you guys do?
Background and key points of this discussion
The atmosphere in which a creator has to prove whether their own work is “AI or not” is a phenomenon that spread alongside the rapid rise of generative AI, and this time it was a Hello! Project tour logo designer who ended up on the receiving end. What divided opinion in the thread wasn’t the merits of the suspicion itself, but the sheer burden placed on the person forced to prove their innocence. As post 22 points out, 700 hours works out to roughly 29 days by simple math, prompting pushback over whether anyone actually reviewed footage that long. The other fault line was over generative AI itself, with supporters and opponents hurling insults like “geezer” and “moron” at each other, drifting the discussion away from Satō Masaki herself and the logo that started it all. It’s also worth noting that exactly which tour’s costumes and logo “last year” refers to was never pinned down — post 24 raises the possibility it actually means this past summer’s shows — and this remains unconfirmed within the thread.
※This article is excerpted and summarized from the 5ch (Hello! Project) thread “[Sad News] Satō Masaki: “Rumors spread that last year’s tour logo was AI-made, so I pressed the creator about it and they submitted 700 hours of proof footage” — isn’t this way too rude?“.
