This article discusses the legal drinking age in Japan, which is 20 years old. However, 18 year olds can legally drink if they are accompanied by an adult over the age of 20. The laws are strictly enforced by police and store owners, and minors cannot purchase beer from vending machines or convenience stores without a parent or guardian present. Other alcoholic beverages such as sake and shochu are also subject to the same laws. If 18 year olds are travelling with an adult over the age of 20, they can purchase beer and wine from most convenience stores and supermarkets. Japanese society generally frowns upon underage drinking, so it is best avoided in public settings.
