Japanese is easier to learn than English, like, way easier. The hard part is reading/writing but they'll understand fine if you just use Hiragana/Katakana instead of Kanji or use Romaji (English is taught in schools).

You are xenophobic. You joined a JP party and said "I don't speak Japanese" as if you were expecting them to communicate solely in English for your benefit. And now you're wanting segregated servers just because you're unwilling to try and communicate without using English. Auto-translate feature works well enough for parties...Behests on my server are usually completed 100% with auto-translate.

It also helps if you get on at UK/NA times and not Eastern EU/Asia times.
