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.
