Smoking has been a part of Japanese culture for centuries, but in recent years there have been changes in attitudes towards it due to increased awareness about health risks associated with tobacco use. According to WHO estimates from 2016-2017, roughly 30% of adults are still smokers, however this rate has been declining since 2004 when 33% were smokers. Government regulations have made it more difficult to purchase cigarettes or smoke indoors in public places, and various campaigns have been launched to reduce the popularity of smoking. Public opinion surveys show that most people support stricter laws regarding where people can legally smoke within their own homes.
