The codification of sword etiquette dictated that a samurai would wear both a katana and wakizashi, a long and short sword, opposite their dominant hand and bound to the body via an obi (sash). This is specific to juxtapose this orientation should be noted as different from a separate, more traditional cavalry sword known as a tachi (or dachi depending upon romanization) which is worn suspended from the waist by a cord, and was generally out of fashion by the Edo period. Due to many manga, anime, and Japanese prose being set in the Edo period, the roles of these swords are often mentioned if not a central theme or focus of the work. There is a significant degree of anachronism present in popular culture in relation to these swords as well, giving rise to series such as Afro Samurai, Samurai Jack, Gintama, and countless videogames, television shows and movies which feature especially the katana prevalently.
