Weed in Osaka: Laws, Risks, and Public Perception

Osaka, Japan’s third-largest city, is famous for its vibrant nightlife, delicious street food, and lively entertainment districts. However, when it comes to cannabis, Japan has some of the strictest drug laws in the world, and Osaka is no exception. Unlike some Western countries where weed is becoming legalized or decriminalized, Japan enforces severe penalties for cannabis possession, use, and distribution.
