Osaka, Japan, has announced a new policy prohibiting smoking on all city streets, effective January 27, 2025. The ban covers all forms of smoking, including conventional cigarettes, e-cigarettes, and vaping devices, which were previously less regulated in certain areas. With a population of approximately 2.75 million, Osaka is now one of Japan’s largest cities to implement such a rule, aiming to improve air quality and public comfort in outdoor spaces.
