That letter from the city: what it is and what to do

Resident tax, health insurance bills, pension slips, missed-delivery notes, overdue reminders. How to tell in 30 seconds whether a Japanese letter needs you to act, and how to pay it at the convenience store.

The 30-second check

Before translating the whole thing, look for these words. They tell you almost everything:

If you seeIt means
納付書 (nōfusho)A payment slip. You need to pay something.
納期限 / 期限 (nōkigen / kigen)The due date. Usually written in the Japanese era: 令和8年 is 2026.
督促状 (tokusokujō)Overdue reminder. You missed a payment. Act this week.
催告書 (saikokusho)Final warning. Pay or call them now.
至急 / 重要 (shikyū / jūyō)Urgent / important.
申請 / 届出 (shinsei / todokede)An application or something you must report.
返信用 (henshin-yō)A reply envelope. They want something back.
口座振替 (kōza furikae)Direct debit. If it says this, they'll take the money from your bank.
お知らせ / ご案内 (oshirase / go-annai)Just information. Usually nothing to do.

Don't throw away anything from your city office (区役所 / 市役所), the pension service (日本年金機構) or the tax office (税務署) until you know what it is.

Resident tax (住民税, jūminzei)

Arrives around June. It's the local tax on last year's income, charged by the city you lived in on 1 January. That's why your first year in Japan often has no resident tax, and the year after you arrive has a surprise bill.

National Health Insurance bill (国民健康保険, kokuho)

If you're on National Health Insurance, the yearly bill usually arrives in June or July, split into monthly or bi-monthly slips. The amount is based on last year's income in Japan, so your first year is often cheap and your second year goes up.

Income dropped, or lost your job? You can apply for a reduction. Ask at the insurance counter: 保険料の減免はありますか? (Is there a reduction on the premiums?)

Pension slips (国民年金, kokumin nenkin)

From the Japan Pension Service (日本年金機構), not the city. If you're 20–59 and not on a company pension, you'll get a booklet of monthly slips. The amount is the same for everyone, roughly ¥17,000–18,000 a month, and changes each April.

LetterWhat to do
不在連絡票 (fuzai renrakuhyō) · missed deliveryA parcel came while you were out. Scan the QR code to book a new delivery time, in English on most carriers' sites.
個人番号通知書 · My Number noticeYour 12-digit number. Keep it safe; it has the QR code to apply for the card.
マイナンバーカード交付通知書 · card readyYour My Number card is ready. Book a time and bring the notice, your residence card and the old notice.
健康診断 / がん検診 · health check vouchersFree or cheap check-ups from the city. Optional, but good value.
確定申告 · tax returnFrom the tax office, if you need to file (freelancers, side income, leaving mid-year). Deadline is usually mid-March.
在留カード (residence card) remindersYour status expires soon. Renewals open three months before the expiry date.

How to pay a slip in two minutes

Most payment slips with a barcode can be paid at any convenience store (7-Eleven, FamilyMart, Lawson) up to the due date. Hand it to the cashier and pay cash. They stamp your half: keep it as your receipt.

If you've missed one

Late payments add a small daily charge (延滞金, entaikin), and ignoring reminders can end in your bank account being frozen. More importantly for you, unpaid tax, health insurance and pension can count against you when you renew your visa or apply for permanent residence.

The fix is almost always simple: call or visit the counter written on the letter, say you want to pay, and ask for a new slip or a payment plan. 分割で払えますか? (bunkatsu de haraemasu ka? Can I pay in instalments?)
