In Japan it is normal to call someone by their last name, calling someone by their first name is normally only used when you are either family, extremely close friends, or in an intimate relationship. So if you are trying to have a character address Takashi formally they would call him Komuro, if one of the things listed above then he would be called by his given name Takashi. Hope I could have helped out.
