Japanese bows date back to the prehistoric
Jōmon period. The long, unique, asymmetrical bow style with the grip below the center emerged during the
Yayoi period (300 BC – 300 AD). Bows became a symbol of authority and power. The legendary first emperor of Japan,
Emperor Jimmu, is always depicted carrying a bow. Some
Emishi tribes, notably the Hitakami, practice horse archery and were noted and feared by the
Yamato Kingship. The use of the bow had been on foot until around the 4th century, when elite soldiers took to fighting on horseback with bows and swords. In the 10th century,
samurai would have archery duels on horseback. They would ride at each other and try to shoot at least three arrows. These duels did not necessarily have to end in death, as long as honor was satisfied. One of the most celebrated incidents of Japanese mounted archery occurred during the
Genpei War (1180–1185), an epic struggle for power between the
Minamoto clan and the
Taira clan that was to have a major impact on culture, society, and politics. At the
Battle of Yashima, the Heike (Taira), having been defeated in battle, fled to Yashima and took to their boats. They were fiercely pursued by the Genji (Minamoto) on horseback, but the Genji were halted by the sea. As the Heike waited for the winds to be right, they presented a fan hung from a mast as a target for any Genji archer to shoot at in a gesture of chivalrous rivalry between enemies. One of the Genji samurai,
Nasu no Yoichi, accepted the challenge. He rode his horse into the sea and shot the fan cleanly through. This feat is still celebrated to this day. During the
Kamakura period (1192–1334), mounted archery was used as a military training exercise to keep samurai prepared for war. Those archers who did poorly might find themselves commanded to commit
seppuku, or ritual suicide. One style of mounted archery was
inuoumono – shooting at dogs.
Buddhist priests were able to prevail upon the samurai to have the arrows padded so that the dogs were only annoyed and bruised rather than killed. This sport is no longer practised. ==Ritual==
