Kyūdō is the Japanese martial art of archery. Experts in kyūdō are referred to as kyūdōka (弓道家?). Kyūdō is based on kyūjutsu ("art of archery"), which originated with the samurai class of feudal Japan. Kyūdō is practised by thousands of people worldwide. As of 2005, the International Kyudo Federation had 132,760 graded members.
The beginning of archery in Japan is pre-historical. The first images picturing the distinct Japanese asymmetrical longbow are from the Yayoi period (ca. 500 BC – 300 AD). The first written document describing Japanese archery is the Chinese chronicle Weishu (dated around 297 AD), which tells how in the Japanese isles people use "a wooden bow that is short from the bottom and long from the top."
The changing of society and the military class (samurai) taking power at the end of the first millennium created a requirement for education in archery. This led to the birth of the first kyujutsu ryūha (style), the Henmi-ryū, founded by Henmi Kiyomitsu in the 12th century. The Takeda-ryū and the mounted archery school Ogasawara-ryū were later founded by his descendants. The need for archers grew dramatically during the Genpei War (1180–1185) and as a result the founder of the Ogasawara-ryū (Ogasawara Nagakiyo), began teaching yabusame (mounted archery).
From the 15th to the 16th century, Japan was ravaged by civil war. In the latter part of the 15th century Heki Danjō Masatsugu revolutionized archery with his new and accurate approach called hi, kan, chū (fly, pierce, center), and his footman's archery spread rapidly. Many new schools were formed, some of which, such as Heki-ryū Chikurin-ha, Heki-ryū Sekka-ha and Heki-ryū Insai-ha, remain today.
