Are you learning japanese? You might enjoy trying. Duolingo has a free tier which is annoying but the annual sub is reasonable (c. £60) if you look for offers.
Firefox will offer translations. On both sides.
Given the choice between not knowing an answer and having to translate it (using a built-in translator) I’d prefer the answer, but you could always use the translator for them even if the output is garbage-Japanese.
Taking offence is a choice.
I don’t study Japanese. I suggested the most popular app.
