Question:

So i was wondering do people in Japan go by there first or last name ? Umm is it something like : the couples call each other by their first name ? Im soooo confused . I Desided to ask this because i was watching an Anime series , and one of the characters was really suprised when another character called her her name . Im not sure if i was first or last ......Please Help ! : )

Answer:

Well, not everything is anime is true - no matter how much you love anime T_T. But using someone's first name in Japan usually means you're closer to them. Many people in Japan use honorifics (san, chan, sensei, senpai, etc) and call people by their surname/ last name/ family name.
