One of the earliest and most enduring of Japanese marches is the "Defile March" (分列行進曲) composed in 1886 by Charles Leroux, an officer with the French Army serving as an advisor to the Imperial Japanese Army. Originally two separate marches based on Japanese melodies—"Fusouka" (扶桑歌) and "Battotai" (抜刀隊), inspired by the Satsuma Rebellion and reportedly a favorite song of the Emperor Meiji—they were later combined in the march currently recognized today. It soon became a very popular band standard, with the Imperial Japanese Army adopting it as their signature march. After World War II the JGSDF and the Japanese police would adopt the march, where it continues to be a core part of their repertoire.
