That
the ninja (shinobi)
[1] were active in Japan from the 1100s to the 1600s is
a certainty, with the majority of Japanese historians agreeing that
they originated in the ethnic melting pots of Iga and Koga on the
island of Honshu,
a product of the various philosophies, doctrines and
fighting skills brought to that island by Chinese immigrants fleeing
oppression.
Ninja
weapons, many multi-purpose, were also part
of the package. The Shuriken, a palm size throwing blade came in many
shapes all extremely deadly; the Shuko, comprised of spiked metal
bands, slipped over the hands and gave their wearer both catlike
climbing ability and the capacity to defend himself against an
opponents weaponry; the shinobi-zue, a hollow cane in the shape of a
walking stick, could be used as an underwater breathing device, spear
or blowgun, with smaller weapons, darts and poison hidden either inside
its
central cavity or alternately in the space provided by the overly long
scabbard of the ninjato (ninja short sword); and finally their was the
ninja himself, a master of unarmed combat (taijutsu), his body the most
formidable weapon of all.
