Hana Kojima: “I’m Banned From Saying My Old Agency’s Name” — The Unspoken Rule Shared by Every Hello! Project Transfer Member

From our other sites

The story

The thread was sparked by a post noting that Morning Musume。’23’s Hana Kojima said her manager has forbidden her from naming the talent agency she used to belong to. Posters piled on with more examples of transfer members who avoid naming their former agencies — Kasahara (Angerme), Konno (a Morning Musume。 OG), Kawanishi (formerly of Amuse) — and opinions split over whether this is a Hello! Project-specific custom or standard practice across the entertainment industry as a whole. Some defended it (“It’d actually look more unnatural if she didn’t stay quiet about it,” “Might be a copyright or publicity-rights issue”), while others took it as proof that the agency is simply closed off.

That's common knowledge, isn't it
2AnonymousSep 12, 2026 22:30
Is saying "I'm banned from saying it" itself not banned?

Re: #2
Because it gives her a ready excuse when she needs to turn something down — "Sorry, my agency won't let me talk about that."
If anything, it'd look more unnatural if she didn't say that

Well, it's probably better not to go running your mouth about it yourself.
It's fine when fans bring it up on their own, but it kills the vibe once the idol herself starts turning it into a bit
5AnonymousSep 12, 2026 22:32
That's pretty much standard whenever anyone switches agencies.
Kasahara doesn't say Angerme's name either
11AnonymousSep 12, 2026 22:34
Re: #5
Announcer Kitagawa never brings up Morning Musume。 at all either
A little sad, but I guess that's just how it goes
21AnonymousSep 12, 2026 22:36
Re: #11
Konno used to casually say Morning Musume。's name back in her TV Tokyo days,
and even appeared alongside other OGs

Re: #11
Riorio probably can't bring it up because you guys keep grumbling about it

Hana Kojima: "If it weren't for Hello! Project, I think I'd have quit showbiz and gotten a part-time job"
9AnonymousSep 12, 2026 22:34
I wonder if she'll stop appearing on the official One Piece channel now
The cast and staff there clearly know her former agency and group

Hana-chan Kojima: "I can't really say the agency's name… but it's the one over in Ebisu"
13AnonymousSep 12, 2026 22:34
Isn't it just an industry custom?
Not that I'd know

15th Gen: "We're banned from saying there were three of us in our batch"
18AnonymousSep 12, 2026 22:35
Kamo never brought up "Hachikin" either (a former group/nickname reference)
19AnonymousSep 12, 2026 22:36
There's no way you'd name your old agency's other company in showbiz
20AnonymousSep 12, 2026 22:36
She's not allowed to say "People often tell me I look like Ichioka-san"
22AnonymousSep 12, 2026 22:36
Talking about ASH is the one thing that's allowed, right?
23AnonymousSep 12, 2026 22:37
Minamikawa talks about Shochiku all the time though
24AnonymousSep 12, 2026 22:38
There have been a few Hello! Project members over the years from Meguro (Hinode), and apparently there was even a time when naming your old school was off-limits too
26AnonymousSep 12, 2026 22:38
I wonder if she's even allowed to post "met up with a former coworker" on social media
30AnonymousSep 12, 2026 22:40
Re: #26
She's posted on Instagram about hanging out with former coworkers just fine since transferring
Kojima even showed up naturally in a TikTok video posted by an old Stardust colleague
28AnonymousSep 12, 2026 22:39
Doesn't Kawanishi avoid saying it too?
32AnonymousSep 12, 2026 22:43
Re: #28
She does say it
She's even written about Lupinranger vs. Patranger on her blog
34AnonymousSep 12, 2026 22:44
Re: #32
Has she ever actually said out loud, in her own words, that she was with Amuse?
29AnonymousSep 12, 2026 22:40
Even Shizuka Kudo never talks about the Seventeen Club
33AnonymousSep 12, 2026 22:43
Some members bring up their past entertainment careers and some don't
Not sure what the difference comes down to
36AnonymousSep 12, 2026 22:45
Well, it's best not to talk about your old agency at all if you can help it
37AnonymousSep 12, 2026 22:45
She doesn't name it specifically, but she's talked openly about having been in an idol group at a different agency before
38AnonymousSep 12, 2026 22:45
It's probably fine for members who properly graduated
41AnonymousSep 12, 2026 22:46
The other side might have put an NG on it
42AnonymousSep 12, 2026 22:46
People who graduated from Hello! Project and moved to other agencies talk about Up-Front just fine
Guess it's just this crappy agency being weird about it
53AnonymousSep 12, 2026 22:51
Re: #42
Maybe it's different when someone quits an idol group to do something totally unrelated to idol work,
versus switching agencies and going right back to being an idol in another group?
43AnonymousSep 12, 2026 22:47
Stardust's Hana Kojima and Hello! Project's Hana Kojima are different "products" — it's a copyright/publicity-rights thing
45AnonymousSep 12, 2026 22:48
It's because you guys hate their "past life" so much (fan slang for a member's pre-transfer career)
Kawanishi doesn't talk about Amuse either
46AnonymousSep 12, 2026 22:48
How did the conversation even end up here?

Background and Key Points of the Discussion

It’s not unusual in the entertainment industry for a talent who has switched agencies to avoid publicly naming their former one, and this is generally attributed to contractual confidentiality obligations along with the publicity and image rights still held by the former agency. The point raised in the thread (reply 43) about a possible “copyright or publicity-rights issue” lines up with this general understanding. That said, the thread’s reactions were split — some treated it as simply standard industry practice, while others saw it as evidence that Hello! Project (UFA) is especially closed off. Worth noting, though: both takes remain speculation within the thread, and there’s no primary sourcing confirming that any one agency in particular enforces this more strictly than others. It’s also been pointed out (reply 30) that posts about meeting up with former colleagues still appear on social media after a transfer, suggesting the restriction may apply only to publicly naming the agency itself, not to private contact with former colleagues.
