You have just landed in Japan, checked into your hotel, and the first thing you want to do is crack open a cold Japanese beer or try a cup of warm sake. Before you do, there is one number you absolutely need to know: 20. That is Japan's legal drinking age — and it applies to every visitor, regardless of the legal age in your home country.
Japan lowered its age of adulthood to 18 in April 2022, a historic change that surprised many. But lawmakers deliberately kept the drinking and smoking ages at 20, citing concerns about protecting young adults in school and university settings. The result is a country where you can vote and sign contracts at 18, but you must wait until 20 to legally purchase or consume alcohol.
This guide covers everything you need to know: the law, where to buy alcohol, what to expect at convenience store checkouts, how to handle izakaya visits, and the cultural side of drinking in Japan that makes the experience unlike anywhere else in the world.
1. The Legal Drinking Age: 20 Years Old
Japan's alcohol laws are governed by the Minors' Drinking Prohibition Law (未成年者飲酒禁止法), originally enacted in 1922. Under this law, anyone under the age of 20 is prohibited from purchasing or consuming alcohol anywhere in Japan.
Even though Japan lowered its general adulthood age to 18 in 2022, the drinking age remained at 20. This is a common source of confusion for tourists from countries where 18 is the drinking age (like the UK, Germany, or Australia). Japan's law applies to everyone on Japanese soil — your home country's rules do not apply here.
Since April 2022, Japan's legal adulthood age is 18 — meaning 18-year-olds can sign contracts, get married without parental consent, and vote. However, the drinking age, smoking age, and gambling age all remain at 20. These were kept higher to protect young adults still in school from addiction-related harm.
Anyone under 20 may not: buy alcohol at any shop, order alcohol at a restaurant or bar, consume alcohol in public, or receive alcohol as a gift from someone else. Adults who knowingly provide alcohol to minors can also face fines and penalties.
2. Where to Buy Alcohol in Japan
One of the things that surprises most first-time visitors is just how easy it is to buy alcohol in Japan. It is sold in an enormous variety of locations — many of which are open around the clock.
| Location | Hours | What's Available |
|---|---|---|
| Convenience Stores (7-Eleven, FamilyMart, Lawson) | 24 hours / 7 days | Beer, canned sake, chuhai, wine, whisky, non-alcoholic alternatives |
| Supermarkets | Typically 9am – 9pm | Full selection, including premium sake and regional craft beers |
| Liquor Shops (酒屋) | Varies | Specialist sake, rare whisky, local craft beers, gift-packaged sets |
| Izakaya / Bars | Evening onwards | Draft beer, sake, shochu, highballs, cocktails — served at the table |
| Vending Machines | 24 hours (where available) | Canned beer and chuhai — increasingly rare, mainly in rural areas |
3. Age Verification at Convenience Stores
If you have been to a Japanese convenience store before, you may have noticed that the self-checkout terminal asks you to confirm your age before completing an alcohol purchase. This is standard practice across all major chains — and the process is handled entirely by machine, not by the cashier.
Here is how it works at most chains:
Step 1: Scan your items as usual at the self-checkout terminal.
Step 2: When the system detects an alcohol item, a screen appears asking you to confirm that you are 20 years of age or older.
Step 3: Press the confirmation button on the touchscreen. The purchase proceeds.
Staff ID check: If a staff member believes you may be underage — typically if you appear to be in your teens — they may approach and ask for ID. Accepted forms include a passport or a Japanese residence card.
4. Drinking at Izakaya and Bars
The izakaya (居酒屋) — Japan's version of a pub or gastropub — is one of the essential Japanese experiences for any visitor. These casual restaurants serve food alongside drinks, and the atmosphere is relaxed, lively, and extremely welcoming to foreigners.
At an izakaya, alcohol is ordered directly at the table, either from a server or via a tablet ordering system. Age verification is handled by the establishment, and most busy urban izakaya do not card customers unless someone clearly appears underage. However, the legal responsibility remains with the restaurant — and with you.
Draft Beer (生ビール / Nama Biiru): The standard opening order for most groups. Japanese lagers like Sapporo, Kirin, and Asahi are clean, crisp, and perfect paired with bar food.
Sake (日本酒 / Nihonshu): Japan's rice wine, served warm or cold. Ask for junmai for a full-bodied style, or ginjo for something lighter and fruity.
Highball (ハイボール): Japanese whisky mixed with sparkling water. Suntory Toki highball is a safe crowd-pleaser for first-timers.
Shochu (焼酎): A distilled spirit made from sweet potato, barley, or rice. Stronger than sake, usually diluted with water or soda.
• The first drink order comes almost immediately after sitting — "nani ni shimasuka?" ("What will you drink?") is often the opening line.
• Many groups order the same drink for everyone for the first round — this is part of the group dining culture.
• Never pour your own drink. Pour for others at the table, and they will pour for you in return.
• "Kanpai (乾杯)!" is the toast — always wait until everyone has their drink before drinking.
• Nomihoudai (飲み放題) means "all-you-can-drink" — a set price for unlimited drinks within a time limit, usually 90 minutes to 2 hours. Excellent value.
5. Drinking in Public: Is It Allowed?
This is where Japan genuinely surprises most Western visitors. Drinking in public is legal in Japan. There is no national law prohibiting alcohol consumption in parks, on the street, along rivers, or at festivals. You can walk out of a convenience store with a can of beer and drink it on the way to your next destination without any legal issue.
In practice, public drinking is a beloved part of Japanese social culture. Hanami (花見) — cherry blossom viewing parties held every spring — is built around sitting under blooming trees with bento boxes and cans of beer or sake. Riverbank picnics with alcohol are a regular weekend activity in most Japanese cities.
6. Useful Japanese Phrases for Alcohol Situations
Japanese bar and restaurant staff are accustomed to helping foreign visitors, and most major izakaya chains have English menus. But these phrases will make the experience smoother — and the local staff will genuinely appreciate the effort.
| Situation | Japanese | Pronunciation |
|---|---|---|
| Ordering a beer | ビールをください | Biiru wo kudasai |
| What sake do you recommend? | おすすめの日本酒は？ | Osusume no nihonshu wa? |
| One more, please | もう一杯ください | Mou ippai kudasai |
| Cheers! | 乾杯！ | Kanpai! |
| I don't drink alcohol | お酒は飲みません | Osake wa nomimasen |
| Non-alcoholic please | ノンアルコールをください | Non-arukooru wo kudasai |
| The bill, please | お会計をお願いします | Okaikei wo onegaishimasu |
7. Non-Alcoholic Options: Japan Does Them Well
If you do not drink alcohol — or if a member of your group is under 20 — Japan has an exceptional range of non-alcoholic alternatives that go far beyond plain water or soda.
Non-Alcoholic Beer (ノンアル ビール): Japanese craft versions from Kirin and Asahi have improved dramatically in recent years. Available at all convenience stores and most izakaya.
Canned Tea (缶茶): Green tea (matcha), barley tea (mugicha), and houjicha in cans from vending machines — genuinely delicious and uniquely Japanese.
Ramune (ラムネ): Japan's iconic glass-bottle marble soda. The marble acts as a stopper inside the bottle — pushing it down is half the fun.
Amazake (甘酒): A thick, sweet fermented rice drink with essentially zero alcohol. Warm in winter, chilled in summer — often found at shrines during festivals.
Conclusion
Japan's drinking culture is warm, social, and full of ritual — from the kanpai toast to the art of pouring for others before yourself. The legal drinking age of 20 is strictly observed, but as long as you are of age, you will find some of the world's best beer, sake, whisky, and shochu waiting for you at every convenience store, izakaya, and festival vendor. Carry your passport if you look young, try a chuhai from a vending machine, learn to say kanpai, and enjoy one of the most hospitable drinking cultures on the planet.
Frequently Asked Questions
Can I drink at 18 in Japan?
No. Even if you are 18 or 19 years old and the legal drinking age in your home country is 18, Japan's law applies while you are in Japan. The legal drinking age is 20, and it applies to tourists and residents alike without exception.
Will I be asked for ID when buying alcohol?
At convenience stores, a self-checkout screen will ask you to confirm you are 20 or older — this is a tap on the screen, not an ID check. However, if a staff member believes you may be underage based on your appearance, they can and will ask for ID. Carry your passport to be safe.
Is sake stronger than beer?
Yes. Most sake (nihonshu) has an alcohol content of around 14–16%, compared to 5% for standard Japanese beer. If you are new to sake, start with a glass rather than a bottle, and drink it slowly — it goes down smoothly but adds up faster than beer.
Can I bring alcohol back to my home country from Japan?
Yes, in most cases. Japanese sake, whisky, and shochu are popular souvenirs. Check your home country's customs allowance for how much alcohol you can import duty-free — most countries allow 1–2 liters per adult traveler. Specialty sake purchased at a liquor shop will often come pre-packed for air travel.
Is Japan's whisky really as good as people say?
Yes. Japanese whisky from producers like Suntory (Yamazaki, Hibiki, Toki) and Nikka (Yoichi, Miyagikyo) has won multiple international awards and is genuinely world-class. Good bottles are increasingly hard to find domestically due to global demand — if you see something rare in a liquor shop, it is worth picking up.
