The story

Toyo Keizai Online reports that former Juice=Juice member Kanon Miyamoto, despite having no development experience, is building a special tour website entirely on her own using “vibe coding” — writing code by conversing with AI. The trigger was the departure of her manager (nicknamed “Mg”). Struggling to communicate with staff, she reportedly started turning to AI for help. On 5ch’s Hello! Project board, the report sparked a lively discussion covering everything from the reasons behind the manager’s resignation to the treatment of Up-Front-affiliated staff and even assessments of Kanon’s own personality.

Using AI to draft proposals and even prepare revisions… Former Juice=Juice member Kanon Miyamoto shows a new era of idol who does more than just sing and dance

Kanon Miyamoto, who graduated from Hello! Project idol group Juice=Juice and is now active as a solo artist.

Despite having no prior development experience, she has been making use of “vibe coding” — writing code through natural-language conversation with AI —

She's not selling, sounds like they can't even afford staff anymore — better watch what you say

Re: #2
It's probably true
They're short-staffed
3AnonymousSep 10, 2026 12:14
Did 'Magnesium' run off on her? ("Mg" — the manager's nickname doubles as the chemical symbol for magnesium)
4AnonymousSep 10, 2026 12:15
That kind of thing is staff's job
65AnonymousSep 10, 2026 12:49
Re: #4
If she leaves it to the notoriously incompetent Up-Front staff
She'll end up like Michishige
5AnonymousSep 10, 2026 12:15
Couldn't she just use a Google Form for surveys?
6AnonymousSep 10, 2026 12:15
Going through that agency's upper management wasn't getting her anywhere
So I guess she found a language she can use to talk to the people on the ground as an equal
7AnonymousSep 10, 2026 12:16
She's about to turn 28 — done as an idol

Re: #7
Are you dissing Manakan, who's 29?
44AnonymousSep 10, 2026 12:39
Re: #7
Before she turns 30, I really wish she'd consider marrying me
9AnonymousSep 10, 2026 12:21
I mean, couldn't you call this DIY?
10AnonymousSep 10, 2026 12:21
Kanon-chan's drawing power keeps dropping
So they can't afford a dedicated manager who can handle her anymore
And she struggles to communicate with a regular manager
13AnonymousSep 10, 2026 12:21
Once she's no longer an idol, she's finished
She's the type who wants to be the center of attention herself, so she's not cut out for real behind-the-scenes work
14AnonymousSep 10, 2026 12:22
So with Mg gone, AI is the only one left she can talk to?

Narration: Kanon Miyamoto (Juice=Juice OG)


Go get 'em behind the scenes!
16AnonymousSep 10, 2026 12:22
Miyamoto always puts her effort in the wrong direction
This time's no different
25AnonymousSep 10, 2026 12:26
Re: #16
At least what she's done will leave something behind — it's just uncharted territory, which beats what came before
17AnonymousSep 10, 2026 12:23
Since she's such a smooth talker, she's probably more of a handful than Sato
18AnonymousSep 10, 2026 12:23
Re: #8
If it's true, they should be hiding it even harder
26AnonymousSep 10, 2026 12:27
Re: #18
It's not something to hide
The world's shifting toward cutting staff and using AI instead, so if anything she's right on trend
32AnonymousSep 10, 2026 12:28
Re: #26
It gives off such a grim vibe that it's just speeding up fans leaving
21AnonymousSep 10, 2026 12:25
Honestly, though
Kanon Miyamoto barely has any motivation for outside work anyway — she probably didn't need a dedicated manager to begin with
28AnonymousSep 10, 2026 12:27
Re: #21
She's plenty motivated for outside work
Whether the offers actually come in is a different story
22AnonymousSep 10, 2026 12:25
So it wasn't a transfer, she actually quit?
Maybe she went off to open a curry shop

So AI filled the gaping hole Mg left behind by running off
Well, I guess AI was fine for the job
36AnonymousSep 10, 2026 12:29
Re: #27
I wanted to be the one to fill that hole
34AnonymousSep 10, 2026 12:29
So it's come to the point where the talent has to do it herself…

Re: #34
It's the backlash from Miyamoto being the only one in the JP room who got a dedicated manager — she was living too large
39AnonymousSep 10, 2026 12:32
Mg was apparently also busy handling other JP members besides Miyamoto
The pay's bad, so it's not a job you stick with for long
40AnonymousSep 10, 2026 12:34
Re: #39
That's how it ended up partway through
Handling just Kanon-chan alone would leave you with too much downtime
43AnonymousSep 10, 2026 12:38
She was never really 'ours' to begin with, but it still feels like AI took Kanon-chan away from us
I'm aware that sounds creepy
45AnonymousSep 10, 2026 12:39
Re: #43
Isn't that just you being way too resistant to AI?
Think of it like she just started using PowerPoint
46AnonymousSep 10, 2026 12:40
I'm in the 'we don't need a new group' camp, but
if Karin-chan were producing it, I'd want to watch
51AnonymousSep 10, 2026 12:42
Re: #46
There's no way Kanon Miyamoto, who has zero interest in other people, could actually produce anything
53AnonymousSep 10, 2026 12:43
Isn't 'Magnesium' probably a former underground idol?
There's a lot of that going around
72AnonymousSep 10, 2026 12:56
Re: #53
A lot of female managers are pretty cute, right?
Though I've never seen Mg's face
58AnonymousSep 10, 2026 12:46
Up-Front's managers get paid less than at other agencies, after all
66AnonymousSep 10, 2026 12:49
Re: #58
So much rides on the manager, I really wish they'd pay the hardworking ones properly

Background and Points of Debate

The Toyo Keizai Online interview behind this article describes how Kanon Miyamoto uses a technique called “vibe coding” — writing code through natural-language exchanges with AI — and has AI handle everything from drafting proposals to presenting revisions. Opinions on the thread were split over whether to view this as a positive challenge or as a sign of a staffing shortage stemming from the lack of a manager. It’s worth noting that speculation about treatment and staffing at Up-Front-affiliated agencies reflects 5ch conjecture rather than any official statement from Miyamoto herself. Also, “Mg” is a nickname used within the thread to refer to the manager — the reason for departure and the person’s identity have not been disclosed.

*This article is compiled from excerpts and summaries of the 5ch (Hello! Project board) thread “Kanon Miyamoto: ‘Since Mg left, she started using AI to communicate with staff. Now she’s building the special tour site herself’.”
