The bow and arrow provided the majority of weaponry in Heian and early Kamakura Japan. the predominance of the sword did not actually come “into” use, although it was used, until later. The actual ascendancy of the bow and arrow began during the wars before and the Genpei War.
Shooting the bow and arrow became, like most of the arts in Japan, an elaborate and systematic process which required much practice. There are actually eight named stages of shooting an arrow:
1.ASHIBUMI (footing)
2. DOZUKURI (correcting the posture)
3. YUGAMAE (readying the bow)
4. UCHIOKOSHI (raising the bow)
5. HIKIWAKE (drawing the bow)
6. KAI (completing the draw)
7. HANARE (the release)
8. ZANSHIN (continuation) and YUDAOSHI (lowering of the bow, included with zanshin.
You can see all the stages if you watch this short video:
