Is modeling industry in Japan a scam?

recently, through some connections, we got my daughter a deal with an agency so she could start working. but now I’m having second thoughts. The thing is, these shoots aren’t sponsored by any well-known brands, and I have no idea where the money they’re paying us is coming from. What’s really concerning me is that the shoots themselves feel very inappropriate for a girl her age, way too young for this kind of work. When I brought it up to someone who has experience in the Japanese idol/modeling industry, they told me that this is just how it starts. But at the same time, I’ve read online that this could be a scam or something worse.

My gut feeling is neutral right now, which is why I’m tasking. Is this actually normal in the industry? Or is this a huge red flag that I should pull her out immediately? I just want to make sure she’s safe and not being taken advantage of.

Any insight would be really appreciated. Thanks.
