Driving in Snow: Winter Tyres, Chains, Rental Checks and Icy-Road Basics
Before a winter road trip in Japan or Hokkaido: the difference between winter tyres and chains, what to check when renting, and how to brake and corner on ice. About 7 min read · Updated 2026-11-01
Winter driving is one of the riskiest ways to travel. This guide explains tyres and chains, then gives a few habits that really help.
Note: Japan is our main example. Rules differ by country; check local road authorities and your rental company. If you are unsure, using public transport is a perfectly good choice.
Winter tyres, chains and all-season tyres
- Winter (studless) tyres: the basic winter equipment; the rubber stays softer in the cold and grips far better.
- Chains: a temporary tool for heavy snow, steep slopes or restricted sections; not for long drives on dry road.
- Summer tyres: dangerous on snow or ice, and in Japan can be an offence on such roads.
- 4WD helps you start and climb but does not shorten braking distance. Tyres matter more.
Two kinds of winter restriction
- Winter-tyre restriction: winter tyres are fine; ordinary tyres are turned back.
- Chain restriction: all vehicles need chains, even with winter tyres; this happens only a few times a year. Check JARTIC or the expressway sites.
What to check when renting
- In snowy regions (Hokkaido, Tohoku, Hokuriku, Shinetsu) winter tyres are usually standard in winter rates.
- In regions like Kanto they are often optional and must be requested when booking.
- Search for "スタッドレスタイヤ" and confirm the pickup branch really has such cars; ask whether chains are available.
- From December to March, driving from Tokyo into the mountains means assuming snow.
Driving on ice
- Go slower than feels necessary and leave two to three times your usual gap.
- Brake early, lightly and gradually; avoid sudden braking, steering and acceleration.
- Use a low gear downhill.
- Slippery spots: near junctions, bridges, tunnel exits and shade.
- Snow can hide road markings; stop lines help you judge where to stop.
- In a whiteout, slow down, use hazard lights and stop somewhere safe.
- Daylight is short: arrive on mountain roads before dark, keep the tank fuller and keep your phone charged.
Other countries
Canada, Iceland and the Alps have their own tyre and chain rules and dates. Always check official sources.
Our take
On your first snow drive, plan short distances and avoid bad-forecast days. A flexible schedule matters most.
