The drinking age in Japan is 20, not 18. That rule applies to tourists as well as residents, even though Japan lowered its age of majority to 18 in 2022. The difference matters in a country where beer, sake, and canned chuhai are easy to spot in convenience stores and where a simple checkout screen can look less formal than the law behind it.
Japan’s legal drinking age is 20 for residents and visitors
Under the Act Prohibiting Minors from Drinking, people under 20 may not consume alcoholic beverages in Japan. Japan’s legal drinking age is a national rule, so an 18- or 19-year-old visitor does not receive an exception because drinking is legal at that age at home.
The rule has consequences beyond the person drinking. Parents or guardians and sellers can face fines for violations. Since 2000, a seller who knowingly sells alcohol to someone under 20 can be fined, and since 2001, sellers have been required to check customers’ ages.
Japan takes public education on the rule seriously. Each April, the National Tax Agency designates a month for strengthened awareness campaigns to prevent drinking by people under 20, working with ministries and industry groups.
Why being 18 in Japan does not make alcohol legal
On April 1, 2022, Japan lowered the civil age of majority from 20 to 18, its first change to that threshold since 1876. The Civil Code revision had been passed in 2018, with time allowed for schools and society to prepare before it took effect.
That change did not lower every age-based restriction. Alcohol, smoking, and public gambling on horse, bicycle, boat, and motorcycle races all remain limited to people 20 and older. This split is the source of a common travel mistake: legal adulthood for contracts is not the same thing as permission to drink.
| At age 18 | Still requires age 20 |
|---|---|
| Sign a lease without parental consent | Drink or buy alcohol |
| Enter credit-card and phone contracts | Smoke or buy tobacco |
| Take out loans and carry the resulting legal responsibility | Take part in listed forms of public gambling |
Women and men can both marry at 18. Japanese citizens aged 18 and 19 can also apply for a 10-year passport rather than only a five-year passport. They may serve as lay judges in criminal trials, and the minimum age for professional licenses such as those for doctors and tax accountants was lowered to 18. An 18-year-old can therefore count as an adult under Japan’s Civil Code and still not legally order a beer with dinner.
Where to buy alcohol in Japan and what ID checks look like
People aged 20 and older can buy alcohol at supermarkets, convenience stores known as konbini, and restaurants or izakaya. The three major convenience-store chains are 7-Eleven, with about 21,000 locations, FamilyMart with about 16,300, and Lawson with about 14,600. Nearly all are open around the clock.
Beer, chuhai, sake, shochu, wine, and whisky are available in almost every konbini, in cans, bottles, and cartons. Convenience-store prices run about 10–20 percent higher than supermarket prices, but the broad hours and ready-to-drink selection explain the tradeoff.
A checkout button is an age confirmation, not an exemption
At a staffed convenience-store register, buyers commonly press a screen confirming that they are 20 or older. In practice, staff rarely request ID, though they may do so. The screen does not change the customer’s legal age or remove the seller’s responsibility to verify it.
Since January 2024, self-checkout registers may sell alcohol and tobacco when a device scans the buyer’s driver’s license or My Number Card. Restaurants and izakaya are also legally required to check the ages of young guests; in practice, staff usually ask for ID only when a guest looks young. Bring identification if there is any doubt; an age check can happen at the store or when ordering.
An izakaya meal turns a drink into a shared evening
An izakaya is an informal Japanese bar serving alcohol and snacks, comparable in spirit to a British pub or a tapas bar. The word literally means a “stay-drink-place.” Many open around 5 or 6 p.m. and close around 11 p.m. or midnight, often in time for the last trains; some stay open until morning.
Common orders include beer, sake, shochu, chuhai, whisky highballs, and cocktails. A familiar opening order is toriaezu nama, meaning “a draft beer for now.” It gives the table something to drink while everyone considers the food menu.
At many izakaya, each guest automatically receives a small appetizer called otoshi. It is a cover charge, commonly about 300–600 yen, rather than a free snack. Another useful term is nomihodai: an all-you-can-drink plan sold for a fixed price and usually limited to two or three hours. Some chains pair it with tabehodai, an all-you-can-eat offer. A typical izakaya bill is about 2,000–7,000 yen per person, depending on the venue and the order.
Public drinking is broadly legal, but local rules set the boundary
Japan has no national law that generally bans drinking on streets, in parks, or at train stations. That can surprise visitors from places where carrying an open drink in public is routinely prohibited. It is not a license to drink anywhere at any time, however: municipalities and individual parks can make their own rules.
In Shibuya, Tokyo’s busy entertainment district, a local ordinance has prohibited drinking on streets and public squares from 6 p.m. to 5 a.m. every day since June 2024. The rule responded to noise and trash, and it shows why a national general rule is only the beginning of the answer.
Public drinking is often associated with hanami, the cherry-blossom picnic. Alcohol is permitted in most parks during hanami, but a municipality may prohibit it or limit noisy hours. The 1961 Law to Prevent Drunk and Disorderly Conduct also addresses behavior: someone who is noisy or aggressive while drunk may be arrested or fined. Check the rules for the specific park or neighborhood, and do not confuse a quiet picnic with permission for disruptive conduct.
Japanese drinking culture includes beer, chuhai, and sake
Beer is Japan’s most popular alcoholic drink, followed by chuhai and sake. Chuhai is a mix of shochu or vodka, fruit juice, and soda; it usually contains 3–9 percent alcohol. Sake, or nihonshu, is typically 15–16 percent alcohol by volume. Undiluted genshu sake reaches 18–20 percent.
Those numbers make canned drinks worth reading carefully. A 350-milliliter can of 7 percent chuhai, a 500-milliliter can of 5 percent beer, and 180 milliliters of sake each contain about 20 grams of pure alcohol. Japan’s first national alcohol guidelines, published in February 2024, identify 20 grams or more a day for women and 40 grams or more a day for men as health-risk levels.
Drinking can also be social and organized. A nomikai is an after-work drinking event with colleagues, often involving several rounds and an izakaya nomihodai plan. The setting may feel casual, but it does not alter the age rule or make excessive behavior acceptable.
Four common myths about drinking in Japan
- “Japan’s drinking age fell to 18 in 2022.” No. The civil age of majority fell to 18, while the alcohol minimum remained 20.
- “An 18-year-old tourist follows the rules of their home country.” No. Visitors are covered by Japan’s 20-year minimum.
- “Pressing the konbini screen means nobody checks age.” No. It is an age confirmation; sellers have a duty to check age, and ID may be requested.
- “Public drinking is legal everywhere.” No. There is no national ban, but places such as Shibuya have local restrictions, and disruptive drunken behavior can lead to penalties.
