Driving in snow or freezing conditions in Japan requires more than choosing a vehicle with winter tires. Before setting out, check the weather and road status for the whole route, confirm the vehicle’s equipment and rental conditions, and decide whether the trip is within your experience. A road that looks merely wet or dark may be icy, and a chain restriction may require chains even if the vehicle has studless winter tires.
The guidance below is based on official sources reviewed on 4 November 2026. It does not describe the weather, road restrictions, rental availability or emergency conditions on your travel day. Check current instructions from the relevant road operator, local authorities and rental company immediately before travel, and change or postpone your plan if conditions exceed your ability or a road is closed.
1. Decide whether to drive in winter conditions
Start with the decision to drive, not with the assumption that the itinerary must go ahead. Snow and ice can make a route difficult even when conditions at your destination appear clear, and mountain areas can receive sudden snowfall. Toyota Rent a Car notes that snowfall or icy roads may occur between October and May depending on the region, and that sunny weather does not rule out icy surfaces in Hokkaido, Tohoku or mountainous areas. These are general seasonal cautions, not a forecast for your dates. (Toyota Rent a Car winter guidance; Hokkaido winter-driving guidance)
Check conditions along the route, including mountain sections, bridges and the return journey, rather than checking only the start and destination. JNTO cautions that weather-related detours can increase travel time, so a tight schedule may leave little room to respond to a delay. If the route is closed, visibility is poor, equipment is unsuitable or you are not confident driving in the conditions, do not try to force the journey; postpone it or reconsider how to travel. (JNTO winter-driving guidance)
A past trip, video or clear-weather image cannot establish that a road is open or safe today. Check the relevant road operator’s current notices and follow signs and instructions on the route. The official general guidance reviewed for this article does not establish travel-day closures or whether a restriction is active.
2. Winter tires, chains and restrictions
Winter tires and chains are not interchangeable in every situation. Japan’s Ministry of Land, Infrastructure, Transport and Tourism advises fitting winter tires on all wheels for severe snowy or icy roads, while NEXCO Central says chains are required under a chain restriction even when a vehicle has studless tires. A four-wheel-drive vehicle or winter tires alone should not be treated as permission to pass a chain restriction. Check the current instructions for the exact road section and vehicle. (Transport ministry winter-tire guidance; NEXCO Central chain-restriction guidance)
| Item | What the reviewed guidance says | What to confirm before your trip |
|---|---|---|
| Winter tires | JAF recommends winter tires for snow and ice; the transport ministry advises winter tires on all wheels for severe snowy or icy roads. | Which tires are fitted to the actual rental vehicle, whether they suit your route and the rental provider’s current terms. |
| Chain restriction | NEXCO Central says chains are required under a chain restriction even with studless tires. | Whether a restriction is currently in force on your exact section and what the operator requires for your vehicle. |
| Rental equipment | Toyota Rent a Car says winter tires can be selected as an option where needed and that some locations include them. | Branch, vehicle, price, availability, equipment and permitted use. |
| Road status | General guidance does not establish whether a road is open or a restriction is active on your travel day. | Current road-operator notices, local instructions and weather along the route. |
NEXCO Central’s guidance lists designated sections that include Chuo Expressway Iida-Yamamoto–Sonohara and Sutam a–Nag asaka, as well as Hokuriku Expressway Maruoka–Kaga and Kinomoto–Imajo. A section being designated is not evidence that a chain restriction is active there today. Check the operator’s current instructions before using any such section, and do not rely on a past notice or a route that looks clear. (NEXCO Central chain-restriction guidance)
The sources reviewed do not provide a standard rental price for winter tires or chains, a branch’s chain stock or current reservation availability. Ask the rental company directly about the vehicle and equipment you will receive, any additional cost and whether your planned route is permitted under its current terms. Do not assume that equipment supplied at one branch is available at another.
3. Arrange a suitable rental vehicle and prepare before departure
Ask about winter equipment when arranging the rental, not after reaching a snowy road. Toyota Rent a Car advises selecting winter tires as a vehicle option where needed and notes that some locations include them. The actual equipment, price and availability depend on the branch and vehicle, so confirm those details with the provider rather than relying on a general description. (Toyota Rent a Car winter guidance)
Before leaving, check the full route, including conditions between your starting point and destination, mountain sections and the return. Confirm the weather and current road notices for those sections, then check again close to departure because the guidance here is not a live status report. Build enough flexibility into the plan to respond to a closure, worsening visibility or a delay; JNTO notes that weather-related detours can extend journey time. (JNTO winter-driving guidance)
Use this pre-departure checklist:
- Vehicle and equipment: Ask which tires are fitted and whether chains or other equipment are available. Confirm the branch’s current price, availability and instructions, and ask what to do if a restriction applies to your route.
- Route and conditions: Check current weather and road notices for the entire journey, not just the destination. Confirm the status of any mountain or expressway sections you plan to use.
- Visibility: Clear snow from the roof and make sure the windows and mirrors provide a clear view before driving. Snow left on the roof can slide onto the windscreen when braking. (JAF snow and ice guidance)
- Fuel and supplies: Check the fuel level. Hokkaido’s guidance recommends preparing items including chains, a shovel, booster cables and a tow rope, but the reviewed information does not establish that every rental includes these items or that they are appropriate for every vehicle. Ask the provider what it supplies and how to use any equipment with that vehicle. (Hokkaido winter-driving guidance)
- Ability and plan: Make sure you are authorised and suitably experienced for the vehicle and route, and check the rental provider’s current requirements. Set a clear alternative if a road closes, visibility deteriorates or the conditions exceed your experience.
A prepared vehicle does not make every road safe, and a checklist cannot replace current instructions. If you cannot confirm that the vehicle and equipment are suitable for the route, ask the rental provider before departure. If the answer is unclear or conditions change, delay or revise the plan rather than testing the limits on the road.
4. Recognise ice and snow-hidden road edges
Black ice is thin ice that can look like wet pavement. Hokkaido warns that dark-looking roads in early winter may still be frozen, while JAF notes that a sudden drop in temperature after rain can also produce black ice. JAF further cautions that an icy road can be even more slippery than a snow-covered one, so do not judge grip by appearance alone. (Toyota Rent a Car winter guidance; Hokkaido winter-driving guidance; JAF snow and ice guidance)
Take particular care near intersections, pedestrian crossings, railway crossings, bridges and shaded sections, all identified in Hokkaido’s advice as places where winter surfaces need attention. Toyota also highlights tunnel entrances and exits. These locations may have changing surface conditions, so approach cautiously and avoid treating a stretch of apparently clear road as proof that the next one has the same grip. (Hokkaido winter-driving guidance; Toyota Rent a Car winter guidance)
Snow can conceal the boundary between the carriageway, pavement and shoulder, as well as gutters and changes in road level. JAF notes that roadside arrows and reflective poles may help indicate road edges, but these markers are references, not a guarantee that the edge is safe to drive over. Follow current signs and road instructions, and do not assume that a snow-covered verge is a usable part of the road. (Toyota Rent a Car winter guidance; JAF snow and ice guidance)
5. Reduce speed, leave more space and respond to poor visibility
Hokkaido advises slowing down early and leaving a longer following distance on winter roads than on dry roads. It also recommends engine braking. JAF advises gentle acceleration when starting and cautions against sudden lane changes. These are general precautions rather than a formula for a safe speed or stopping distance on a particular road, so adapt to the actual vehicle and conditions. (Hokkaido winter-driving guidance; JAF snow and ice guidance)
Make inputs smooth: accelerate gently when moving off, avoid sudden lane changes and allow room to respond without abrupt manoeuvres. These precautions matter because a surface that looks wet may be icy, and an icy road can be more slippery than one covered with snow. Clear roof snow before departure as well as clearing the windows and mirrors; JAF warns that roof snow can slide onto the windscreen during braking and obstruct your view. (JAF snow and ice guidance)
If visibility becomes insufficient in a whiteout, do not force progress. Toyota advises waiting in a safe place when visibility is inadequate, and JAF says that if a blizzard prevents progress, drivers should use hazard lights and stop in a safe place. Follow local authorities’ and road operators’ instructions for the conditions you encounter; a general article cannot identify a safe stopping place on your route. (Toyota Rent a Car winter guidance; JAF snow and ice guidance)
6. If snow blocks the exhaust or the vehicle is stranded
JAF warns that snow blocking the exhaust can create a risk of carbon-monoxide poisoning. If you are waiting for rescue, JAF’s winter-road advice says to remove snow around the exhaust. The reviewed source does not let this article assess whether a particular stopped vehicle or location is safe, so follow current emergency and local-authority instructions for your circumstances. (JAF snow and ice guidance)
Before travel, ask the rental provider how to contact its assistance service and what its breakdown or closure procedures are. Check current road, weather and emergency information for the roads and prefectures on your route, and keep the provider’s instructions available. The sources reviewed do not establish your travel-day conditions, a branch’s chain stock or what a particular insurance policy covers; confirm those matters with the responsible provider.
If conditions make continuing unsafe, do not treat arrival time as more important than the road instructions or your ability to proceed. Use the current directions from road operators and local authorities, and contact the rental company or assistance service as appropriate to the situation. For wider trip planning, consult the related JGO! guides on Japan driving, international driving permits in Japan and Japan winter weather, while verifying current legal, road and rental requirements with the relevant authority or provider.
7. Frequently asked questions
Do winter tires mean I can drive through a chain restriction?
No. NEXCO Central’s reviewed guidance says chains are required under a chain restriction even when a vehicle has studless tires. Check the current restriction and instructions for the exact road section and vehicle before travelling. A section’s designation in general guidance does not establish that a restriction is active on your travel day. (NEXCO Central chain-restriction guidance)
Can a dark or wet-looking road be icy?
Yes. Hokkaido warns that a dark-looking road in early winter may be frozen, and Toyota describes black ice as thin ice that can resemble wet pavement. JAF also warns that black ice may form after rain when temperatures drop suddenly. Treat appearance as an unreliable guide to grip and check current conditions. (Hokkaido winter-driving guidance; Toyota Rent a Car winter guidance; JAF snow and ice guidance)
Are winter tires included with a rental car?
Not necessarily. Toyota Rent a Car says some locations include winter tires, while others offer them as an option to select when arranging the vehicle. Confirm the actual branch, vehicle, price and availability directly with the rental provider; the reviewed sources do not give a universal price or guarantee that a particular vehicle will be available. (Toyota Rent a Car winter guidance)
What should I do if a whiteout prevents me from continuing?
Do not force progress when visibility is insufficient. Toyota advises waiting in a safe place, while JAF says to use hazard lights and stop in a safe place if a blizzard prevents progress. Follow current local-authority and road-operator instructions, since this general guidance cannot identify a safe location for your particular road. (Toyota Rent a Car winter guidance; JAF snow and ice guidance)
Why clear snow from the roof before driving?
JAF warns that snow on the roof can slide onto the windscreen during braking and block the driver’s view. Clear the roof before departure as well as making sure the windows and mirrors are unobstructed. Follow the rental provider’s instructions for the vehicle. (JAF snow and ice guidance)
What equipment should I ask the rental company about?
Ask which tires are fitted and whether chains are available, and confirm the branch’s current price, availability and instructions. Hokkaido recommends preparing chains, a shovel, booster cables and a tow rope, but the reviewed guidance does not establish that every rental supplies them or that every item fits every car. Ask the provider what it supplies and what is appropriate for your vehicle and route. (Hokkaido winter-driving guidance; Toyota Rent a Car winter guidance)
