Legal Drinking Age in Japan 2025 | Rules, Culture & Laws

When it comes to traveling abroad, knowing the local rules around alcohol is essential. If you’re planning to visit or live in Japan, you might be wondering: What is the legal drinking age in Japan? The answer is simple — the legal drinking age in Japan is 20 years old. While adulthood in Japan officially begins at 18 (after the law changed in 2022), drinking and smoking laws still apply only to those who are 20 and older.

In this blog, we’ll cover the legal drinking age in Japan, cultural norms around alcohol, strict rules for underage drinking, and how Japan compares with other countries.

What Is the Legal Drinking Age in Japan?

The legal drinking age in Japan is 20 years old. Anyone under this age is not legally allowed to purchase or consume alcohol. Stores, restaurants, and bars are very strict about checking ID, and most require proof of age such as a passport or residence card if you appear young.

Why the Drinking Age Is 20 in Japan

Historically, the age of adulthood in Japan was set at 20. Even though the legal age of adulthood was lowered to 18 in April 2022, the government decided to keep the drinking and smoking age at 20 to protect young people’s health and safety.

Drinking Culture in Japan

Drinking is a big part of Japanese culture and social life. Alcohol is often consumed during:

• Nomikai (drinking parties) with colleagues
• Festivals like Hanami (cherry blossom viewing)
• Family gatherings and celebrations

What’s unique about Japan is that public drinking is legal. You can drink in parks, on the street, or even on trains — though being respectful and responsible is expected. Convenience stores sell alcohol 24/7, making it easily accessible for those who are of legal age.

Rules and Penalties for Underage Drinking

Underage drinking in Japan is taken seriously. Businesses that sell alcohol to minors can face heavy fines or even lose their license. For individuals under 20 caught drinking, social consequences and parental notification are common.

Public Drinking Laws in Japan

Unlike many countries, Japan does not ban public drinking. People often gather in public places like riversides or parks with drinks, especially during cherry blossom season. However, being disruptive or causing trouble while drunk can lead to police intervention.

Drunk Driving Laws: Zero Tolerance Policy

Japan has one of the strictest drunk driving laws in the world. The legal blood alcohol content (BAC) limit is 0.03%, far lower than in the U.S. (0.08%). Even one drink can put you over the limit. Penalties include:

• Heavy fines
• Jail time
• License suspension
• Punishment for passengers who allowed a drunk driver to operate a car
