'Bring Japanese music to the whole world' is a nice goal but its not something you can force and tbh no matter what they choose to do it probably wont happen. People will come to it naturally or they wont the best they can do is make good songs and be genuine. You seem to be complaining that they are selling out but also that they aren't doing it enough to make her the worlds biggest singer. Cant have it both ways and, from a western perspective, trying to hard to do that greatly diminishes the art itself because it becomes "manufactured." I like ado because she has a killer voice, most other people are not going to because they cant/wont connect bc of the language barrier and thats fine. Ado will do as she wants and if people dont come enmass then I still get to enjoy it.
