Bajutsu (馬術) is a Japanese form of military equestrianism.
Although its origins are closely related to those of mounted archery (yabusame), bajutsu is considered a distinct and separate martial art, and there are a number of traditional
schools, such as the Ogasawara, Otsubo, and Hachijo. The art originated in the 7th century AD during the reign of Emperor Tenji but was popularised in the 12th century as large-scale
mounted warfare became more common. However, the comparative scarcity of horses in Japan meant that bajutsu was always an elite art, restricted to high-ranking samurai. In spite of
this, many contemporary historians ignored the numbers of foot-soldiers in battles and referred to the size of armies by the number of horsemen alone.
