Talk:Rintarou Okabe/@comment-667468-20131128152600/@comment-85.167.32.74-20140216001415

Okabe is indeed his last name. In Japan, it is customary to call others by their last name. First names are often only used by people who are close with each other, or to differentiate people who have the same last names. You can add honorifics (san, kun, sama etc.) to both the given and last names. We could call him Rintarou from this point on, but I'm afraid I see no point in changing it to his given name, since he is the only Okabe in this series. And yes, we could start calling everyone else by their last names too, except for those who have the same surnames, such as Yuugo and Nae Tennouji, to avoid confusion.
