I am a Japanese native speaker, whom learning Korean on the course.
First of all, “~은 (~는)” stands for “〜は; 〜が（助詞）”, which is not a problem.
However, there’s a word with a problem. “~이에요 (~예요)” also stands for “〜は; 〜が（助詞）”, but it’s an incorrect translation! It should stand for “～です”!
If I could contact the admins of this site, I could report the problem.
So to administrators, could you fix the translator right now, please?
