Japan Tourist Bans & Laws 2026: Things Not To Do & What is Illegal?

The "Ghosn" Reality Check: Strict Justice

Japan is one of the safest countries on Earth, but its legal system is terrifying for foreigners who make mistakes.

• 99% Conviction Rate: If you are charged, you will likely be convicted.

• 23-Day Detention: Police can hold you for 23 days without charge, with limited access to a lawyer. This is not "innocent until proven guilty"; it is "hostage justice."

The "Big Red Line": Strict Bans You Must Know

1. The "Zero Tolerance" Drug Trap

Japan does not mess around with drugs. There is no concept of "personal use amount" for leniency.

• Cannabis: Possession of even a tiny amount can lead to 5 years in prison and immediate deportation. Do not bring "residue" on your clothes or bags from countries where it is legal (like Canada or Thailand).

• The Risk: If you are caught, you will likely disappear into the detention system for weeks.

2. The Kyoto "Paparazzi" Ban (Updated 2026)

In Kyoto’s famous Gion district, local patience has run out.

• The Ban: It is now illegal for tourists to enter private alleys in Gion.

• The Fine: ¥10,000 (approx. $65 USD).

• The Rule: Stick to the main Hanamikoji Street. If you see a "No Entry" sign, it is legally binding, not a suggestion. Do not chase Geishas for photos.

3. Shibuya’s "Dry Street" Law

As of late 2024/2025, the Shibuya Street Drinking Ban is in effect year-round, not just on Halloween.

• The Rule: No drinking alcohol on the streets around Shibuya Station from 6:00 PM to 5:00 AM.

• The Penalty: Police patrols will confiscate your drink.

The "Traffic & Scooter" Trap

This is the #1 way tourists get fined or detained in Japan.

The IDP Trap (1949 vs. 1968)

WARNING: Japan ONLY accepts International Driving Permits (IDP) based on the 1949 Geneva Convention.

• The Trap: Many European countries issue IDPs based on the 1968 Vienna Convention. These are invalid in Japan. If you drive with a 1968 IDP, you are "Driving Without a License," which is a criminal offense punishable by arrest.

• Check Before You Fly: Your IDP must say "1949 Convention" on the cover.

Electric Scooters (LUUP)

Rental scooters (like LUUP) are everywhere in Tokyo/Osaka.

• Speed Limit: 20km/h max.

• Age: 16+ (ID verification required in-app).

• Alcohol: Strictly Prohibited. Riding a scooter after one beer is the same legal offense as drunk driving a car. You face massive fines (up to 500,000 JPY) or jail.

Substance Rules: Vaping, Alcohol & Meds

⚠️ Critical Warning: Many common meds (like Sudafed or inhalers) can be illegal. Before you pack, you MUST read our detailed guide on Japan Airport Customs Rules 2026: Alcohol, Meds & Prohibited Items

Niche & "Weird" Laws

• No Walking & Smoking: In major wards like Chiyoda (Tokyo), smoking on the street is banned and results in an immediate 2,000 JPY fine. You must stop in a designated "Smoking Area."

• The "Skirt Photo" Law: Japan has a specific criminal ordinance against taking photos up skirts or of people in sexualized manners without consent. Shutter sounds on Japanese phones are mandatory by law for this reason.

• Pocket Knives: Carrying a Swiss Army Knife or pocket knife with a blade longer than 6cm without a "valid reason" (self-defense is not a valid reason) is a crime.

Cultural Taboos (Don't Be Rude)

While not "illegal," breaking these will get you kicked out of establishments.

1. Tattoos in Onsens: 90% of public baths (Onsens) still ban tattoos (gang association). Cover them with a patch or find "Tattoo Friendly" onsens.

2. Shoes Indoors: Stepping on the tatami (straw mat) with shoes (or even slippers) is a grave insult. Socks or bare feet only.

3. Train Silence: Talking loudly on the phone on the train is considered aggressive and rude. Text only.
