When moving to Japan, it’s easy to focus on the exciting parts—food, culture, and new opportunities. But to truly live comfortably and avoid unnecessary trouble, it’s also important to understand the everyday rules and laws that shape life here.
They might seem strict or unusual at first, but many are designed to promote safety, harmony, and respect in shared spaces.
Here are some of the essential laws and local rules that every foreign resident should be aware of — not to scare you, but to help you adapt smoothly and avoid unintended issues.
1. Resident Registration and Carrying Your Residence Card
Why it matters: Essential for everyday life, from opening a bank account to getting a phone.
If you’re staying in Japan for more than 90 days, you must complete your resident registration at your local city hall within 14 days of moving into your new address. This registration is a legal requirement and also allows you to receive a My Number (social security and tax number) and access municipal services.
In addition, foreign residents are required by law to carry their Residence Card (在留カード / Zairyū Card) at all times. Police officers may ask to see it during an identity check. Failure to present it can result in penalties, including fines.
2. Garbage Separation Rules
Why it matters: Waste sorting in Japan is a serious matter—and each city has its own system.
Garbage is typically divided into burnable, non-burnable, recyclables, and sometimes more specific categories like PET bottles or small electronics. In most neighborhoods, you can only throw out certain types of waste on designated days.
Not following the rules can lead to your garbage being left behind with a warning sticker—or even complaints from neighbors. Check your local municipality’s guide (usually available in English) when you move in.
3. Smoking and Drinking in Public
Why it matters: The rules protect both your safety and public health.
While Japan has many bars and izakayas, public smoking is heavily restricted. Many cities, especially Tokyo’s central wards, have designated smoking areas. Smoking outside those zones, especially while walking, may lead to fines.
Drinking in public, on the other hand, is technically legal—but drunken behavior (e.g., being loud or disruptive on trains) is socially frowned upon and can invite police attention.
Note: The legal age for both drinking and smoking is 20 years old in Japan.
4. Riding a Bicycle in Japan
Why it matters: Bicycles are a common form of transportation—but not a free-for-all.
Even though many Japanese residents casually ride bicycles, the laws are clear.
- You must have a working headlight if riding at night.
- Biking under the influence of alcohol is prohibited.
- Using a smartphone or umbrella while cycling can lead to fines.
Legally, you’re supposed to ride on the street unless sidewalks are explicitly marked for bicycles.
Also, bicycle registration (防犯登録) is mandatory and helps prevent theft. Theft is relatively rare in Japan, but umbrellas and bicycles are easily stolen, so be careful.
5. Noise Consideration in Apartments
Why it matters: Cultural norms around noise differ—Japan values quiet and privacy.
Walls in Japanese apartments are often thin. Making loud noises (especially music, phone calls, or parties) late at night can disturb your neighbors. Quiet hours usually start around 10 PM, and repeated complaints can even result in warnings from the building management.
Living in Japan is a rewarding experience, and understanding local rules and laws helps you make the most of it. These regulations aren’t meant to intimidate; rather, they’re designed to maintain the order and mutual respect that make Japanese society function so smoothly.
If you’re aware, respectful, and proactive, you’ll find that adapting to these systems becomes second nature — and your life in Japan will be much more enjoyable and stress-free.
