A note on the "season" nomenclature: The seasons that comprise the following list correspond to the box sets released in North America by Funimation. However, these "seasons" only correspond to story arcs, and not to the pattern in which the show actually aired in either Japan or the United States. In Japan, Yu Yu Hakusho was aired year-round continuously, with regular pre-emptions for sporting events and television specials taking place, not split into standard seasonal cycles.
