Carrying Your Residence Card and What Happens If Police Stop You in Japan
Updated: 2026-09-17
Quick answer

Hi, I'm Miya, and I help newcomers settle into life in Japan. Being stopped by a police officer in a new country can feel unsettling, even when you've done nothing wrong. In Japan, brief questioning on the street or a quick bicycle check is a fairly routine part of daily life, and it usually ends within a few minutes. This guide covers carrying your residence card and what to expect if an officer approaches you; for what the card itself is, or for finding legal help, we have separate guides.
The short version: if you're a mid- to long-term resident, carry your residence card (zairyū kādo, 在留カード) with you at all times and show it when a police officer asks. Stay calm and polite, answer simple questions, and say so if you don't understand, because asking for English or an interpreter is perfectly fine. If you left the card at home or lost it, explain honestly, follow the officer's instructions and report a lost card promptly. This is general information, not legal advice, so please check guidance from the Immigration Services Agency and your local police for the details that apply to you.
Carrying your residence card at all times
Under Japan's immigration rules, mid- to long-term residents are generally required to carry their residence card at all times and to present it when asked by a police officer, an immigration officer or certain other authorised officers. This applies whether you're commuting, shopping nearby or just out for a walk. Children under 16 are usually exempt from the carrying requirement, and short-term visitors carry their passport instead. Not carrying the card when you're required to can lead to penalties, so it's worth turning it into a habit.
A simple routine helps: keep the card in the same slot of a wallet or card holder you always take with you, and check it's there before you leave home. A photocopy or a photo on your phone can be handy for your own records, but it generally doesn't replace carrying the real card. Keep the card clean and undamaged so the details stay readable. It's also a good idea to glance at the expiry date now and then so it doesn't catch you by surprise.
What a routine police stop usually involves
Questioning by a police officer on the street is called shokumu shitsumon (職務質問). Officers may approach people near stations, in busy shopping areas or late at night, and being approached doesn't mean you're suspected of anything. Typically the officer greets you, asks where you're going or where you live, and asks to see ID, which for foreign residents usually means the residence card. Sometimes they may also ask what's in your bag.
Most stops are short and end once the officer has checked your card and your answers. Officers often note down a few details or confirm them by radio, which can take a few minutes. Street questioning is generally based on voluntary cooperation, although showing your residence card when asked is a legal requirement for mid- to long-term residents. If you're unsure about a request, such as opening your bag, you can politely ask what it's for, and the officer will usually explain.
Bicycle checks: what the officer is looking for
Bicycle checks are one of the most common ways people meet the police in Japan. Bicycles are generally required to have an anti-theft registration called bōhan tōroku (防犯登録), and an officer may stop you to check the registration sticker against their records to confirm the bike hasn't been reported stolen. They may also ask for your name and your residence card. If everything matches, you're usually on your way in a few minutes.
It helps to register a bicycle in your own name when you buy it and to keep the registration copy slip somewhere safe. If you bought a used bike or borrowed one from a friend, the registered name may not match yours, so be ready to explain where it came from and, if possible, how to reach the owner. Officers may also mention things like riding without a light at night. Riding safely and keeping your paperwork in order makes these checks even smoother.
Staying polite and getting language help
The best approach is to stay calm, stand still and speak politely. A simple 'sumimasen' (excuse me) and 'hai' (yes) go a long way, and there's no need to argue or walk away. If you don't understand, say so: 'Nihongo ga yoku wakarimasen' (I don't understand Japanese well) or 'Eigo wa daijōbu desu ka?' (Is English OK?). Asking for help causes far less confusion than pretending to understand.
Officers may use a translation app, a phrase sheet or a phone interpreter, and you can ask whether an interpreter (tsūyaku, 通訳) is available. It's generally fine to ask if you can call someone you trust, such as a friend, your employer, your school or a consultation line for foreign residents, especially if you're asked to go to a koban or police station. If a situation becomes more serious, you can ask to contact your country's embassy or consulate, and our guide to finding legal help explains where to turn. It's also wise not to sign any document you don't understand until it has been explained to you.
If you left your card at home or lost it
If you realise you've left your residence card at home, tell the officer honestly and calmly. They may ask for your name, date of birth, nationality and address and check those details, and in some cases they may ask you to come to a koban or arrange for the card to be brought. How this is handled depends on the situation, so follow the officer's instructions and ask if anything is unclear. Carrying another ID such as your passport may help confirm who you are, but it doesn't replace the card.
If the card is lost or stolen, report it to the police first and keep the receipt number. You then generally need to apply for a replacement at your regional immigration bureau within 14 days of noticing the loss, usually bringing your passport, a photo and proof of the police report. Until the new card is issued, keeping the police receipt with you can help you explain the situation. Procedures can change, so confirm the current steps with the Immigration Services Agency (出入国在留管理庁) before you go.
Keep your phone ready for these moments
In moments like these, your phone quietly does a lot of work. You may want to call a friend or your employer, reach a consultation line, or open a translation app so you and the officer can understand each other, and all of that is much easier with a Japanese phone number and data that simply work. It's a good idea to save a few important contacts in your phone ahead of time, too. Setting up a number is simple: you apply online with your residence card, verify with a quick eKYC, and eSIM-capable phones can often connect the same day in about fifteen minutes.
