Abarenbo Shogun is a long-running Japanese jidaigeki television series that first aired in 1978, starring Ken Matsudaira as Tokugawa Yoshimune, a shogun who disguises himself to fight corruption in Edo. Its theme music became closely linked with the character's dramatic arrivals and righteous confrontations, helping the show remain a familiar part of Japanese popular culture for decades. Clips of the theme later spread online through video edits and soundboards, where the short musical cue is now reused far beyond the series for heroic, nostalgic and comedic entrance moments.
