earliest evidence of cannabis in Japan dates back to the Jomon Period
(10,000-200 B.C.), with pottery
relics recovered in Fukui Prefecture containing seeds and scraps of
woven cannabis fibers. Cannabis was the most important substance for
prehistoric people in Japan. They wore clothes made from its fibers
and they used it for bow strings and fishing lines.
is likely that the variety of cannabis from which these Jomon Period
fibers originated was cannabis sativa. Tall-growing and valued for
its strong stems, it is from sativa strains that today’s specially
bred industrial hemp is derived.
