Sapporoculture & etiquette

Sapporo is divided into ten wards, and you must register at the office covering your address within fourteen days of moving in. That registration produces the jūminhyō certificate, starts your My Number, and is the precondition for health insurance, most bank accounts and a phone contract. The grid address helps — Kita and Higashi are literally north and east of the origin — but the ward boundaries do not follow the numbered blocks tidily, so check before you travel. Fourteen days is a statutory deadline, not a suggestion.

Heating a Sapporo flat costs roughly JPY 15,000–30,000 a month from November to April, mostly kerosene, and Hokkaido Electric Power charges among the highest unit rates in the country so an all-electric flat is worse. Add winter tyres, possibly a road-heated parking space, and a neighbourhood contribution towards hauling snow off your street. Newcomers compare Sapporo's low rents against Tokyo's and conclude it is cheap. It is cheaper — but only if you have counted the winter.

Jūminzei is assessed on the previous calendar year's income and collected from the following June. Your first year in Japan produces almost none; your second carries the full weight of your first year's earnings. If you leave partway through a year you can still owe residence tax on money you have already spent. Settle it or appoint a tax representative before you go — this is the most common financial shock among people finishing a stint in Japan.

If your employer runs shakai hoken it is handled for you. If not — freelancers, part-timers, anyone between jobs — you enrol in National Health Insurance and the National Pension yourself at the ward office, and back-payments can be demanded. The pension has a lump-sum withdrawal claimable within two years of leaving Japan, worth a real sum after a few years of contributions, and it is forgotten constantly.

What heats the flat, who buys the fuel, and where does the snow go. Central heating with a shared boiler is billed by consumption; an FF kerosene stove means you order deliveries yourself; electric panel heaters on Hokuden rates are the expensive trap. Then ask whether the property has anywhere to put snow, because tipping it into the road is unlawful, and whether the parking is road-heated. Hokkaido housing is genuinely insulated and double-glazed in a way Honshu's is not — but only the stock built to modern standards.

Sapporo's central grid counts blocks north, south, east and west from the corner of Ōdōri and the old Sōsei River, so 'Kita 5-jō Nishi 2-chōme' is five blocks north and two blocks west of the origin. You can find an unfamiliar address without a map, which is impossible in almost every other Japanese city. The system frays at the edges of the city and in the older Toyohira and Minami districts, so do not extrapolate too far.
