There is no given name for the entire world which the setting describes, so "Rokugan" is used alternately to refer to the specific nation within the setting or to refer to the entire world. Strictly speaking this is incorrect, but as the Emperor lays claim to all that is as a right of being the descendant of Amaterasu (Lady Sun) and Onnotangu (Lord Moon), the courtiers of the Emerald Empire would see this as an appropriate use. The citizens and rulers of the Burning Sands and Ivory Kingdoms might disagree, however. Some say that Ningen-Do, the name of the metaphysical realm in which the world is placed, serves as a proper name for the world.
