Using Your Zairyu (Residence) Card in Daily Life in Japan

Quick answer (30 seconds): Your zairyu card (在留カード, residence card) is your main ID as a mid/long-term resident — and by law you must carry it on you at all times (a passport doesn't substitute once you have the card). You'll show it constantly: opening a bank account, getting a phone, signing a lease, starting a job, at the city office, and if police ask. Two things people forget: you must report certain changes to Immigration within 14 days (address changes go to the city office), and you must renew the card before it expires — separate from renewing your visa status. Lose it? Report to police and apply for a reissue at Immigration within set deadlines.

The carry-at-all-times rule

By law, mid- to long-term residents must carry the residence card at all times and present it if an immigration officer or police officer asks.

• Keep it on you, not at home — failing to carry it can lead to a fine.
• Special permanent residents carry a different certificate, not the zairyu card.
• A photo on your phone is not a substitute — carry the physical card.

Where you'll actually use it

The zairyu card is the document that makes daily life work:

• Bank account: required ID (with your My Number and sometimes proof of address).
• Mobile phone / SIM contract: required for a postpaid line.
• Renting an apartment / lease & guarantor: to prove your status and period of stay.
• Starting a job: employers check your status and work eligibility (the back of the card shows work permission).
• City/ward office: insurance, My Number, certificates.
• Police check (shokumu shitsumon): you must show it on request.

The card's back shows your work eligibility and any "permission to engage in activity other than that permitted" (資格外活動) — important for students and part-time work.

Don't miss the deadlines: changes within 14 days
