>>2505810Being scouted is much less about your singing talent and much more about how you look and what you're willing to do. Vocalists that actually care about their craft and the integrity of their art are generally undesirable.
You want someone that looks like a model and will look great with their face on promotional material. If they can sing, that's a plus, but as long as they aren't completely Noel-tier tonedeaf the industry just assumes they can beat signing skills into them with months of grueling training, and then smooth out the edges post-production since all japanese music is horribly overproduced anyways.
Talent is literally not valued. What is valued is appearance and a complete lack of dignity. You should swing by /jp/s JAV thread sometime. It's nothing short of miraculous how many successful pop artists and idols in Japan end up as pornstars after a few years.
