From lively izakaya bars to quiet sake tastings, Japan’s drinking culture is deeply woven into everyday life. Whether it’s celebrating the end of the workweek with coworkers or enjoying a beer during cherry blossom season, alcohol plays a major social role across the country. But before you raise your glass, it’s important to understand the drinking age in Japan and how Japan’s alcohol laws differ from those in other countries. The legal drinking age in Japan is 20 years old, and it applies to everyone, including foreigners, exchange students, and tourists. While alcohol is easily available at convenience stores and restaurants, Japan enforces strict rules to maintain safety and social order.

In this guide, you’ll learn everything you need to know about the drinking age in Japan: the laws, penalties, cultural norms, and tips for responsible drinking, so you can enjoy Japan’s unique nightlife and traditions without crossing any lines.

Legal Drinking Age in Japan

The legal drinking age in Japan is 20 years old. This rule is defined under the Minor Drinking Prohibition Act (未成年者飲酒禁止法), which strictly forbids anyone under 20 from buying or consuming alcohol, no matter their nationality. That means whether you’re a Japanese citizen, an exchange student, or a tourist visiting Japan, you must be at least 20 years old to legally drink alcohol.

What You Can and Can’t Do

✅ You can:

  • Buy alcohol at convenience stores, supermarkets, restaurants, and bars after turning 20.
  • Drink in public (parks, beaches, festivals), as long as you behave responsibly.

🚫 You can’t:

  • Purchase or drink alcohol before the age of 20.
  • Ask someone else to buy it for you, both of you can be penalized.
  • Use fake IDs.

ID Checks

Most shops, izakaya, and restaurants perform ID checks if you look under 25.
Acceptable forms of identification include:

  • Passport
  • Residence card (在留カード)
  • Japanese driver’s license

Cashiers may ask you to tap a confirmation screen stating “I am over 20” (20歳以上です). Even this carries legal weight, pressing “yes” underage is considered falsification.

💡 Tip: Always keep your ID with you, especially if you look young. Japan takes underage drinking seriously, and fines can apply to both the buyer and the seller.

What the Law Says (and Penalties)

Japan’s alcohol regulations are strict but clear. The drinking age in Japan is enforced under the Minor Drinking Prohibition Act, which aims to protect young people’s health and maintain social order. This law doesn’t only apply to minors; it also holds sellers, restaurants, and even adults accountable if they provide alcohol to someone under 20.

Key Legal Points

  • Underage drinking is prohibited — anyone under 20 who drinks alcohol is violating the law.
  • Supplying alcohol to minors (even by accident) is punishable by fines or imprisonment.
  • Shops and restaurants that sell alcohol to underage customers risk losing their business licenses.
  • Parents or guardians who allow minors to drink can also be held responsible.

Penalties

OffensePossible Penalty
Drinking under 20Official warning, fine, or police notice
Selling to a minorTreated as document falsification, it can lead to criminal charges
Providing alcohol to minorsSimilar penalties, plus business license suspension
Fake ID useTreated as document falsification, can lead to criminal charges

Cultural Enforcement vs. Police Enforcement

Unlike some countries, Japan doesn’t have officers checking IDs on the street. However, store clerks and restaurant staff are trained to enforce the law strictly. Most underage cases are handled quietly, but repeated or public violations can escalate quickly, especially for foreigners, where visa issues or deportation may follow serious offenses.

💡 Remember: In Japan, following the rules isn’t just about avoiding trouble, it’s about showing respect for the community and the people around you.

Japanese Drinking Culture

Understanding the drinking age in Japan also means understanding how people drink. Alcohol is more than a beverage here; it’s a key part of Japan’s social life, from office parties to seasonal celebrations.

Nomikai: The Group Drinking Tradition

The word nomikai (飲み会) literally means “drinking party.” These gatherings happen everywhere — among coworkers, classmates, or friends — and are often seen as essential to building trust and harmony (wa).

During a nomikai:

  • It’s polite to pour drinks for others, not for yourself.
  • Wait for the group kanpai! (cheers) before drinking.
  • Leaving your glass empty is a subtle sign you’re ready for a refill.

💡 Tip: Even if you don’t drink alcohol, you can join! Order a non-alcoholic beer or juice, participation matters more than the drink itself.

Drinking as Part of Japanese Etiquette

Drinking together is often about showing respect and humility. Bosses pour for employees, and juniors (kohai) refill their seniors’ (senpai) glasses, reflecting Japan’s hierarchy and politeness culture.

Hanami picnic, drinking age in Japan

It’s also common to drink during seasonal events:

  • Hanami (cherry blossom viewing) in spring
  • Bonenkai (year-end parties) in December
  • New Year’s celebrations with sake (otoso)

But regardless of the occasion, drinking age rules still apply — no one under 20 can legally join in the alcohol consumption.

Overdrinking Is Frowned Upon

While drinking is socially accepted, public drunkenness that causes disturbance (meiwaku kōi) is heavily discouraged. Japanese people value moderation and self-control, even in festive environments.

💬 Cultural insight: The drinking age in Japan reflects a deeper idea that adulthood begins at 20, when individuals are trusted to act responsibly, both legally and socially.

Before you move to Japan, it’s helpful to understand a few cultural differences.

Where and When You Can Drink

One unique thing about Japan’s drinking culture is that alcohol is easily available — almost everywhere and at any time. But even though it’s accessible, the drinking age in Japan still applies strictly: only people 20 and over can buy or consume alcohol, no matter the setting.

Convenience Stores & Supermarkets

Convenience stores (konbini) like 7-Eleven, FamilyMart, and Lawson sell alcohol, including beer, wine, sake, and cocktails in cans.

  • Alcohol sales are allowed only to customers 20+.
  • Expect to be asked to confirm your age on the touchscreen before paying.
  • Stores typically stop selling alcohol between 11 p.m. and 6 a.m. (varies by region).

💡 Tip: Don’t be fooled by how easy it is to buy alcohol — Japan’s system relies on honesty and self-responsibility.

Restaurants, Bars, and Izakaya

In izakaya (Japanese pubs), alcohol is central to the menu. Staff will ask for ID if you appear under 20.

  • Many offer “all-you-can-drink” (nomihoudai) plans — but only for customers 20 and older.
  • Some izakayas even ban entry for minors altogether, even if they don’t plan to drink.

Drinking in Public Spaces

Unlike many countries, drinking in public is legal in Japan.

  • You can enjoy a beer in parks, at the beach, or by the river — especially during hanami (cherry blossom season).
  • However, local governments sometimes set temporary bans during festivals or busy seasons to prevent littering or noise complaints.

Always clean up your trash, leaving empty cans behind is considered meiwaku (bad manners).

Festivals and Seasonal Events

Japan’s matsuri (festivals) often feature food stalls and sake stands. Drinking is part of the fun, but again, only for adults over 20. Festival organizers sometimes mark alcohol-free zones or use wristbands to identify drinkers of legal age.

💬 Remember: While Japan allows public drinking, it also expects quiet, respectful behavior — another reason why the drinking age in Japan is tied to maturity and accountability.

Drinking and Driving in Japan

If there’s one rule Japan enforces more strictly than the drinking age, it’s the law against drunk driving. Even a small amount of alcohol can get you into serious legal trouble.

Japan’s Zero-Tolerance Policy

Japan follows a zero-tolerance policy toward drinking and driving.

  • The legal limit is 0.03% blood alcohol concentration (BAC) — far lower than in most countries.
  • In practice, this means one drink can already exceed the limit.
  • Police conduct random roadside tests, especially at night or during holidays.

💡 Tip: If you plan to drink, use public transportation or taxis — Japan’s train network and late-night buses make it easy.

Strict Penalties

The consequences of driving after drinking are severe, even for foreigners:

OffensePossible Penalty
Driving under the influenceUp to 5 years in prison or ¥1,000,000 fine
Riding in a car with a drunk driverUp to 3 years in prison or ¥500,000 fine
Providing a vehicle to a drunk driverUp to 5 years in prison
Employer liability (if employee drinks at work event)Company fines and license review

🚨 Even passengers who knowingly ride with an intoxicated driver can face punishment, a reflection of Japan’s culture of shared responsibility.

Foreign Residents and Tourists

For international residents, drunk driving can result in:

  • Immediate license suspension or revocation
  • Visa cancellation or deportation
  • Being barred from re-entering Japan

Japan takes these cases seriously; there’s almost zero tolerance for exceptions.

Alternative Options

Japan offers safe and affordable alternatives:

  • Daiko services (代行運転) — professional drivers who drive you and your car home.
  • Taxis — available in most cities 24/7.
  • Public transport — trains run late in major areas like Tokyo and Osaka.

Non-Alcoholic and Low-Alcohol Alternatives

If you’re under the drinking age in Japan or simply prefer not to drink alcohol, you’ll still find plenty of options to enjoy Japan’s vibrant social life. Japanese culture embraces inclusivity at social gatherings, and there are many creative alternatives to alcohol that let you take part without breaking the law — or the fun.

Non-Alcoholic Beers and Cocktails

Japan’s beverage industry offers an impressive variety of non-alcoholic beers (ノンアルコールビール) and mocktails that look and taste just like the real thing — minus the alcohol.
Popular brands include:

  • Asahi Dry Zero
  • Kirin Zero Ichi
  • Suntory All-Free

You can order these at most izakaya, restaurants, and convenience stores. They’re marketed for drivers, health-conscious adults, and those under 20 who still want to join the cheers (kanpai!).

Traditional Japanese Drinks

If you’d rather skip imitation beers, Japan has countless traditional beverages that suit any occasion:

  • Green tea (緑茶 / ryokucha) – served hot or cold at nearly every meal.
  • Calpis (カルピス) – a sweet, yogurt-like soft drink.
  • Ramune (ラムネ) – the famous marble soda, a nostalgic summer favorite.
  • Yuzu juice (柚子ジュース) – a refreshing citrus drink often served in bars and cafes.

💡 Tip: Many izakaya include a soft drink menu just for non-drinkers, don’t hesitate to ask.

Low-Alcohol Drinks (For 20+)

For adults above the drinking age in Japan, there are also low-alcohol options like:

  • Chu-hi (チューハイ) with 3%–5% alcohol
  • Umeshu soda (梅酒ソーダ) — a mild plum wine cocktail
  • Highball with light whiskey and soda

These are popular among people who prefer to drink moderately or enjoy longer social gatherings without overdrinking.

Joining the Party Without Drinking

In Japan, saying “I don’t drink” (nomemasen / 飲めません) is completely acceptable.
Most Japanese people will respect your choice, especially if you still participate in the conversation and group toast. The important part is joining the experience, not the alcohol itself.

💬 Cultural note: The drinking age in Japan may define when you can drink — but it doesn’t define how social you can be.

Conclusion

Turning 20 is a milestone in Japan; it marks the beginning of legal adulthood and the right to drink responsibly. The drinking age in Japan isn’t just a rule; it reflects a cultural value of maturity, respect, and self-control.

Whether you’re a student, traveler, or new resident, understanding these laws helps you integrate smoothly into Japanese life and enjoy everything from izakaya nights to hanami picnics without worry.
