Winter Driving in Hokkaido (Snow & Ice Safety)
If you’re not used to snow, a Hokkaido winter (roughly November–March) is harder than it looks. Build slack into your plans and drive far slower than usual.
Car and preparation
- Winter rental cars normally come with studless winter tires. Confirm when booking and choose 4WD if you can.
- Check road information (closures, blizzard warnings) before leaving.
- Keep the tank at least half full — towns are far apart and you need heat if stuck.
Driving on slippery roads
- Avoid sudden starts, sudden braking and sudden steering.
- Keep at least double your usual following distance.
- Brake early, gently and in stages.
- Black ice (ブラックアイスバーン) looks like wet asphalt. It’s common on bridges, tunnel exits, shaded spots, early mornings and at night.
- Stop lines at intersections get polished and very slippery.
Blizzards and visibility
Strong wind can blow snow into a whiteout (地吹雪) where you can’t see ahead. Slow right down and turn on your lights. If it feels dangerous, wait somewhere safe such as a rest area or convenience store.
Also watch out for
- Ezo deer jump onto roads, especially at dusk and night — when one crosses, others often follow.
- Days are short (sunset around 4 pm in Sapporo in December). Finish long drives in daylight.
- When parking overnight, lift the wipers so they don’t freeze to the glass.
- Clear snow off the roof, windows and lights before driving.
