The story
In a voice training video for Hello! Project trainee unit Rosy Chronicle, vocal coach Hidetaka Sugai showed a stern expression while putting the members through their paces, sparking discussion on a 5ch live-commentary thread. Sugai has long been known for his fiery coaching style — famously once making Reina Tanaka cry during practice — and while some in the thread worried it bordered on power harassment (“pawahara”), plenty of others were appreciative, with comments like “I’m grateful he’s coaching them for real” and “the members seem used to it by now.” Some also read it as Sugai lighting a fire under Rosy Chronicle, who currently isn’t seen as a favorite to win.
What people said
Rosy Chronicle's been slacking on this
If they've been trainees for years and still can't be properly trained, that's on the staff, not them
watching it right now
It is pretty "legit," yeah

July 7, 2026 — Backstage at Juice=Juice's Ria Matsunaga Birthday Event 2026 @ Zepp Haneda, with Rosy Chronicle's Ayana Murakoshi (one of the trainees). Went ahead and posted it since we took the photo.

The idol championship showdown begins
youtu.be/bMDpoI62ZZI
so they need this kind of kick in the pants
Isn't EBiDAN a boy idol group?
Guess he's just nicer to guys, dunno
Do Stardust otaku not get that it's all part of the performance?
Kamei, who got yelled at for cracking up during the "nyaa" bit, had it way worse
Can't wait to get home and watch it lol
If anything I felt some kindness in there
Feels like he used to grill them way harder back in the day
Yumigeta's got that old-school hot-blooded vibe, not like most kids these days
she's probably Sugai's favorite
Yeah, it's streaming on YouTube
Sugai's always been quick to blow his fuse
He's basically a fairy who gifts skills through his rage-fits
They're used to it
our girls are well trained
Well, Reina's the one who makes Coach Sugai cry, lol
Background and Talking Points
Hidetaka Sugai has served as a vocal coach at Hello! Project for many years, and fans have long passed around stories illustrating both his harsh and human sides — from making Reina Tanaka cry during a lesson to unexpectedly indulging a member who said she was hungry. This video appears to be a clip from a YouTube stream tied to an audition project featuring trainee unit Rosy Chronicle, and the thread title’s “as always” nods to the fact that similar scenes have sparked discussion many times before. While some in the thread worried the harshness crossed into power-harassment territory, the more common reaction was positive — comments like “proof he’s taking it seriously” and “the members aren’t even fazed” dominated. Sugai’s coaching style has become something of a running bit (“rage-fit shtick”) among fans, and the gap between first-time viewers’ reactions and longtime fans’ takes is one of the notable features of this thread.
