Are magic mushrooms legal in Japan?
IllegalNo. Psilocybin mushrooms are illegal in Japan, and possession is a criminal offence.
Mushrooms containing psilocybin are designated 'narcotic raw material plants' under a Cabinet Order, a control that took effect on 6 June 2002 after they had been openly sold; psilocybin and psilocin are also listed narcotics. Cultivation is banned except for licensed researchers and carries 1 to 10 years, while possession or transfer carries up to 7 years. Penalties rise for profit-making, and enforcement applies equally to foreign nationals.
