Yumi
This is the basic bow carried by infantry archers. and by samurai who travel independently of armies or other large groups. It is a powerful bow, although not quite as powerful as the dai-kyu, but its curvature makes it inconvenient to use on horseback.
Han-kyu
Smaller than the yumi and generally easier to use and carry, the han-kyu is a popular bow for use by traveling magistrates or scouts who depend upon speed and stealth. A han-kyu is typically crafted from a single piece of wood or horn.
Dai-kyu
Designed to be fired from horseback, the dai-kyu is composed of multiple pieces of wood, horn, or sinew bound together with glue. These are easily the most powerful of the standard bows used by arrned forces in Rokugan, and are considered nearly as valuable by an archer as his katana.
