Yes, fully Japanese, and I can recommend it. I think it's the #2 subscription MMO at the moment, the recent expansion was very well received and there's been a big influx of 'WOW Refugees' but that's mostly because BFA didn't land well.
If anyone is prompted to try it then be aware that everything under ARR (up to level 50) is a real slog. The slower pace didn't bother me but makes some people quit before the good bits.
