Japan

Cannabis laws in Japan follow Japan’s national law. The rules here are set by the broader jurisdiction, and city-level differences are uncommon.

Recreational cannabis is strictly illegal with severe penalties. Certain cannabis-derived medical products are permitted under recent regulations, but whole-plant cannabis remains prohibited. THC-free CBD products may be sold under separate rules, but that does not mean marijuana is legal, and legality can depend on product content and labeling. Enforcement is rigorous.

Quick facts

• Recreational: Strictly illegal
• Medical: Limited to approved medicines
• Possession: Criminal offense with harsh penalties
• Buying/Selling: Illegal
• Tourists: No exceptions; strict enforcement

Practical guidance

Avoid cross-border transport of cannabis products. Do not assume informal tolerance equals legality.
