Hokkaido Winter Driving from Sapporo: Tyres and Road Rules

Should you drive in Hokkaido this winter?

Start with the physics. Hokkaido's English winter driving leaflet, published with the island's rental car associations, gives full-braking distances from 50 km/h of about 10 m on dry pavement, 35 m on compacted snow and 112 m on icy roads. On ice you need more than ten times the dry-road distance. It singles out "black ice", which looks like a wet road but is the slipperiest surface of all.

Then match the trip to your experience and the forecast.

The leaflet is blunt about bad days: if bad weather is forecast, do not go out, even if it means changing your plans. Some areas have no mobile reception, and rescue can take hours in extreme cold.

Do Hokkaido rental cars come with winter tyres and 4WD?

Toyota Rent a Car fits winter tyres as standard at all its Hokkaido shops during the designated winter period and applies a seasonal rate, noting that the period can change. Nippon Rent-A-Car says 4WD is standard on all its Hokkaido cars in the winter season and that winter tyres are free in heavy-snow areas; elsewhere it charges ¥2,200 to ¥3,300 per day.

The legal side is set by prefectural rules. The tyre manufacturers' association summarises them: on snowy or icy roads you need winter tyres on all wheels or chains, and the penalty for an ordinary car is ¥6,000.

How do you check Hokkaido road conditions in winter?

Winter closures in Hokkaido are often decided on the day. Use these before setting off and at rest stops.

• The Drive Traffic map in English, built on JARTIC data, shows closures, chain regulations, accidents and "winter tires required" sections.
• The Hokkaido Regional Development Bureau publishes an English winter driving guide, English flyers and a map of places where blizzards cut visibility.
• For a fallen sign, a pothole or a hazard on a national road or expressway, call the road emergency dial #9910. It is free and answered 24 hours.

If a whiteout or snowdrift stops you

The development bureau's English flyer is clear: stay in the car. In a blizzard, anyone who walks away from the car risks losing track of where it is. Switch on hazard lights and give the police as much detail as you can about your position, using the kilometre posts on expressways.

Roadside rest areas called michi-no-eki are open 24 hours with parking and toilets, and the bureau suggests using them whenever the snow feels dangerous.

Deer on the road

Hokkaido recorded 6,705 collisions with Ezo deer in 2025, according to the Hokkaido Government. About 41% happen in October and November, and more than 70% between 16:00 and midnight. Deer travel in groups, so when one crosses, slow down and expect more. Their eyes reflect headlights before you see the animal.

Which Japanese road rules do visitors often miss?

Snow gets the attention, but many problems for visiting drivers come from everyday rules that differ from home.

The crossing rule is Article 33 of the Road Traffic Act. The red-light rule comes from Article 2 of the Enforcement Order: vehicles already turning in the junction may clear it, but nobody starts a turn on red. Fine amounts are taken from the Metropolitan Police Department's fine table.

Alcohol

Article 65 of the Road Traffic Act bans driving after any drinking. The National Police Agency sets out the criminal penalties:

• Driving with 0.15 mg or more of alcohol per litre of breath: up to 3 years' confinement or a fine of up to ¥500,000.
• Driving drunk, regardless of the reading: up to 5 years or up to ¥1,000,000.
• Lending a car to a driver who then drives drunk: the same penalties as the driver.
• Riding as a passenger with, or serving alcohol to, a drunk driver: up to 3 years or ¥500,000, or up to 2 years or ¥300,000 where the driver was over the breath limit but not judged drunk.

For a group trip, that means the person who pours the drinks and the friend in the passenger seat are also exposed.

When a rule breach reaches the rental company

Parking is the most common way a fine follows a rental car. Toyota's terms ask you to settle a parking violation during the rental at a police station in the same prefecture where the sticker was left, then show the police paperwork and receipt when you return the car. If you do not, Toyota charges ¥25,000 for an ordinary car, reports the case, and warns that Rent-a-Car Association members across Japan may refuse to rent to you again.

After any collision, including a deer strike or a slide into a snowbank, call the police before the rental company. Toyota's insurance excludes accidents that were not reported to the police.

How much are expressway tolls from Sapporo?

Hokkaido's expressways are usually the safest option in snow, and they are not expensive. Ordinary-car tolls from the NEXCO toll search for 24 September 2026:

Foreign passport holders can buy the Hokkaido Expressway Pass through participating rental offices: ¥7,700 for 4 days, rising to ¥15,400 for 8 days for an ordinary car, with a rental ETC card required. A Sapporo to Asahikawa round trip costs ¥6,760 at normal tolls, so the pass needs more than that one journey to pay off. Our guide to ETC cards and expressway passes explains how the card works.
