Budo Taijutsu, meaning "the art of the body of the way of war," is a term encompassing ancient Japanese martial arts.

Unlike modern martial arts with "-do" suffixes, Taijutsu refers to older fighting forms.

The Bujinkan system incorporates nine ancient schools, including those focused on Koshijutsu, Koppojutsu, Jutaijutsu, Dakentaijutsu, and Ninpo Taijutsu.

Some schools trace their origins back to the 1100s. These schools are documented in the Bugei Ryuha Daijiten, a record of pre-Meiji era Japanese martial traditions.

This highlights the historical significance and depth of Budo Taijutsu.
