This paper traces the abuse of drugs and anti-drug policy in Japan dur
ing the pre-war, war, and post-war eras. The analysis is divided into
six historical periods that examine the purported antecedents, the his
torical background, and the various governmental and societal counterm
easures adopted to combat the drug problem. Producers, traffickers, an
d consumers of drugs in Japan are identified and discussed. The paper
also addresses drug countermeasures including responses from legislatu
res, society, criminal justice personnel, and the medical community. T
he paper argues that Japan's 'war on drugs' in the 1980s was a direct
result of pressure from the United States to adopt harsher sanctions a
nd from a punitive Japanese public that associates drug use with poor
self-control. It concludes that Japan should not emulate the punitive
policies of the United States because they are inconsistent with histo
rical criminal justice practices in Japan and because little evidence
shows they have reduced supply or demand in the United States.
