I honestly wish more JPs would do that. There is something endearing about people learning your language that translates well into streams imo. ESL talents that stream completely or majorly in EN are always fun, like Tenma, Pikamee or IRySMore like the JP side of vtubing has been saturated full for over 2 years, I am surprised at how few japanese streamers have picked the IRyS route and signed up for an EN group. I know the japanese in general do not care about english nor anything that happens outside their island, but surely they'd have caught on by now on how large a worldwide audience with disposable income is.
