Lately people around me has been talking about this, and I had kinda curiosity to know about this, I have years out of japan and H!P and I found out Sayumi is the actual leader and some new girls on the group.
OK I had to read the complete interview and I took the time to hear the recording (realizing my Japanese speaking is still good xD), I just have something to say….

THE FANS ARE OVERREACTING

Again,,, making a big scandal about something isn’t so important, and just spreading the panic/hate as always, that was one of the reasons I got tired about being a H!P fan, the “Fans” and later the girls started to fight to get more “Fans” that was I really hated about.
Ok as I could hear was a normal conversation about something so much of us already knew, Koharu always wanted to be a Model I remember some interview in … can’t remember the show… but was about resonant blue single ( I remember cause I translated that video) and in there Koharu mentioned she really wanted to be a model and started to playing jokes about. I mean that is something that has Years in Koharu’s mind seeing it like this is normal she told that in the radio show, cause that was her dream…

next and I think the real guilty about this are the show’s moderators,, Sanma and the someone other (Can’t remember) why?
I’m not new in that Radio shows, I know how that persons love to act. they are irritating people, yey they are funny but all their jokes are about making anyone get angry or make fun about them, that’s their job cause that is usual in the Japanese Showbiss being cruel and things like that, maybe new persons doesn’t remember the “International H!P fans” matter.
maybe not too much people know about in Japan there is a law which prohibit to make fun about Japanese wotas in TV shows. BUT that law doesn’t says anything about international Fans, then they went to Spain, Mexico, England and some other countries to film H!P wotas , I remember the fans were excited to appear in a Japanese TV show, even I was in the recording (backstage not appear xD) I must confess I was excited too, and was the surprise when the report appeared in the TV Show and the persons in there only made fun of how ridiculous they were, ok they never told that directly, but with the jokes they made was enough to understand it.

Well knowing how works the showbiss in Japan where make fun of someone is very popular in there, the persons in the radio show are used to provoke bad reactions. now Mix:
Koharu a liberal girl whose dream is becoming true
Sayumi a emotional girl whose love for the Idols is really big
and 2 cruel persons who enjoys made angry people.

Result: Easy

We know the rest of the story, Koharu felt bad about she said and Sayu finished angry and now everyone knows about “Young Town” and Sanma.
It is sad to see how Fans just hate only for hate I don’t think Koharu said something bad, she told
“I always wanted to be a model, and MM helped me to reach that dream”

And that is true. Ok was a bad way to say it but Koharu wasn’t always the smartest when about speech we discuss, and was worst say that in front of Sayu who loves Idols more than anyone, and even worse give that Radio show material to keep feeding the fire.
But is far from the reality to say that Koharu is saying She always hated MM and H!P.
cause I heard that comment, and that made me search about this.
This is just Fan Shitty who are overreacting (again).
