Japan lowered its age of adulthood from 20 to 18 in April 2022 — but that change did not lower the drinking age, smoking age, or gambling age. Those remained at 20 for public health reasons. The result is a two-tier system that confuses many visitors: you are legally an adult at 18, but you cannot drink, smoke, or enter most nightclubs until you are 20.
Here is the complete, accurate breakdown of every age restriction that matters to tourists in Japan.
Quick Reference: Age Limits in Japan
| Activity | Minimum Age | Notes |
|---|---|---|
| Drinking alcohol | 20 | Applies to purchasing and consuming. Law applies to tourists regardless of home country rules. |
| Smoking / tobacco | 20 | Cigarettes, e-cigarettes, heated tobacco (IQOS). Vending machines require Taspo card. |
| Nightclubs (serving alcohol) | 20 | Most clubs enforce this strictly. ID required at entry. |
| Gambling (pachinko, horse racing) | 20 | Under-20s cannot enter pachinko parlours or bet on horse/boat races. |
| Driving (car) | 18 | International driving permits accepted for short visits. |
| Voting | 18 | Lowered from 20 in 2016. |
| Legal adulthood (成人) | 18 | Lowered from 20 in April 2022. Allows signing contracts, getting a credit card without parental consent. |
| Marriage (with parental consent) | 18 | Both male and female minimum age is now 18 (previously 18 for males, 16 for females). |
| Tattoo parlours | 18 | No national law — individual parlours set their own minimums, typically 18 or 20. |
Japanese age restriction laws apply to everyone in Japan regardless of nationality or what the law says in your home country. If the legal drinking age in your country is 18 or 16, that does not matter — in Japan, 20 is the minimum for alcohol. Enforcement is real, and being caught drinking underage can result in fines and complications.
1. Drinking Age in Japan
The legal drinking age in Japan is 20. This covers:
- Purchasing alcohol at convenience stores, supermarkets, and vending machines
- Ordering drinks at bars, restaurants, and izakayas
- Consuming alcohol in public spaces where permitted
ID checks at convenience stores
Most convenience stores (7-Eleven, FamilyMart, Lawson) use a touchscreen prompt when alcohol is scanned at the register. The screen displays a message along the lines of: "I confirm I am 20 years of age or older." You tap to confirm. Staff are supposed to check ID if the customer appears underage — in practice, a foreign adult face rarely triggers a check, but it does happen.
Alcohol vending machines
Outdoor alcohol vending machines still exist in some areas, particularly near izakayas and in certain neighbourhoods. These require either a Taspo card or self-confirmation that you are over 20. The honour system is more relaxed than in-store purchasing.
Carry your passport when going to bars or nightclubs. A driving licence from your home country is sometimes accepted but not always. Your passport is the safest and most universally accepted form of ID in Japan.
2. Smoking Age in Japan
The legal smoking age in Japan is 20, covering cigarettes, e-cigarettes, and heated tobacco products such as IQOS and glo.
Taspo card
Cigarette vending machines in Japan require a Taspo card — an age-verified IC card issued only to Japanese residents aged 20+. Tourists cannot get a Taspo card. If you want to buy cigarettes, you must purchase them at a convenience store counter, where staff will serve you without a card (and may ask for ID if you look young).
Smoking areas
Smoking is banned in most public outdoor areas and inside virtually all restaurants and cafés. Dedicated smoking rooms exist in many buildings. Smoking on the street is prohibited in most major cities including Tokyo and Osaka — violations carry fines. Look for designated smoking areas (喫煙所, kitsuen-jo) marked with signs.
3. Nightclub Entry Age
Most nightclubs in Japan that serve alcohol require guests to be 20 or older. Clubs in Roppongi, Shibuya, and Shinjuku enforce this strictly at the door. Staff will ask for ID — passport required.
Even though Japan lowered the legal age of adulthood to 18 in 2022, the laws governing alcohol, tobacco, and gambling specifically were not amended. The Minor Drinking Prohibition Act and Minor Smoking Prohibition Act both set the limit at under 20. Those laws have not changed. Clubs serving alcohol are therefore bound by the drinking age of 20, not the adulthood age of 18.
All-ages events
Some venues host all-ages events (typically before midnight) that do not serve alcohol. These are legal for under-20s to attend. Check the specific event listing — it will state whether it is an all-ages or 20+ event. Music events and concerts at live houses are generally all-ages unless they serve alcohol throughout the venue.
4. Gambling Age
The minimum age for gambling activities in Japan is 20:
- Pachinko parlours: Under-20s cannot enter. Staff at the entrance will turn away anyone who appears underage.
- Horse racing (keiba): Betting requires age 20+.
- Boat racing (kyotei) and bicycle racing (keirin): Also 20+.
- Takarakuji (lottery tickets): 18+ to purchase.
5. The 2022 Law Change — What Actually Changed
Japan's Civil Code amendment on April 1, 2022 lowered the age of majority (成人年齢) from 20 to 18. Here is what actually changed:
| What changed | Before 2022 | After 2022 |
|---|---|---|
| Age of legal adulthood | 20 | 18 |
| Signing contracts without parental consent | 20 | 18 |
| Getting a credit card independently | 20 | 18 |
| Taking out loans | 20 | 18 |
| Minimum marriage age (female) | 16 | 18 |
The following did not change:
- Drinking age: still 20
- Smoking age: still 20
- Gambling age: still 20
- Coming of Age Day (成人の日) ceremonies: still held for those turning 20
FAQ
No. Japanese law applies to everyone inside Japan, regardless of your nationality or home country's drinking age. The legal drinking age in Japan is 20, and this applies to tourists.
Not clubs that serve alcohol. Most clubs in Tokyo, Osaka, and other cities require guests to be 20+. Some all-ages events exist at specific hours, but the standard for nightlife venues is 20.
A passport is the most universally accepted form of ID. Some venues accept foreign driving licences, but practice varies. If you are going out, carry your passport.
Legally, adulthood (成人) is now 18 since April 2022. However, the separate laws on alcohol, tobacco, and gambling retained 20 as the minimum age. So you are legally an adult at 18 but cannot drink, smoke, or gamble until 20.
Generally yes — karaoke boxes do not have a blanket age restriction. However, some karaoke venues do not allow under-18s after a certain hour without an adult, and venues attached to nightclubs may apply the 20+ rule. Check the specific venue's rules. Ordering alcohol at karaoke still requires being 20+.
