This sport can only have been practised by wealthy samurai and perhaps even then only at special festivals or demonstrations for there were (typically) one hundred and fifty dogs released in ten rounds with fifteen dogs to each round. Presumably, because of the blunted arrows, the intention was not to kill the dogs but even with light bows the dogs must have suffered.
The naginata is a halberd-like weapon that was used extensively
in feudal Japan. Described by some as simply "a sword on the end of
a long pole", the naginata was actually a sophisticated weapon which
required considerable skill and stamina to use effectively in
battle.
