Winter TyresWinter Tyres in Japan: Studless Tyres for Hokkaido & the North
The answer for Japan changed with recent regulation updates. Marking standards, enforcement strictness and rental car policies all matter. Details below.
Winter tyres are situationally required in Japan. The rule applies during: Prefectural regulations; Hokkaido, Tohoku require winter tyres in winter.
Studless tyres, because studs are banned in cities
Japan’s winter-tyre rules are prefectural: the snowy north — Hokkaido, Tohoku and the ‘snow country’ of the Japan Sea coast — expects winter tyres, and police or expressway operators can require snow chains on certain mountain passes when it’s falling. The distinctive local twist is that studded tyres are banned in most cities (a 1990 law to curb road-dust pollution), so Japan runs ‘studless’ winter tyres instead — soft-compound rubber that grips ice without spikes. Rental cars in snowy regions come fitted with them in season. In Tokyo or the mild south you won’t need winter tyres at all; head to Hokkaido or the ski resorts and studless tyres are essential.
What the Law Says About Winter Tyres in Japan
Japan follows a situational winter tyre rule.
This means that whenever roads are covered with snow, ice, slush, or black ice, your vehicle must be equipped with appropriate winter or all-season tyres.
In practice, this typically applies during Prefectural regulations; Hokkaido, Tohoku require winter tyres in winter.
Minimum Tread Depth
The legal minimum tread depth in Japan is 1.6 mm.
Safety experts recommend maintaining at least 3.0 mm of tread for adequate winter grip.
Studded Tyres
Studded tyres are allowed with restrictions in Japan. They may only be used during specific months.
All-Season Tyres
All-season tyres (marked M+S or 3PMSF) are accepted in Japan as a winter alternative.

Check Tyre RequirementsWhat Most Guides Don’t Tell You
How Strictly Is This Enforced?
Police in Japan can issue on-the-spot fines for non-compliant tyres during roadside checks. This is especially common at border crossings and mountain passes during winter months.
Foreign-plated vehicles are not exempt. Rental companies in Japan typically fit winter tyres during the mandatory period, but always confirm at pick-up.
All-Season Tyres: Good Enough?
Japan accepts all-season tyres as a winter alternative, provided they carry the correct marking. They work well for mild winters and mixed driving.
However, dedicated winter tyres outperform all-seasons below 7 degrees Celsius. If your route includes mountain passes or areas with regular snowfall, a dedicated set is the safer choice.
Studded Tyres
Studded tyres are permitted in Japan only during specific months and on certain road types. Check the local rules carefully before fitting studs, especially when crossing borders from a country where they are freely allowed.
Insurance Implications
Driving without legally required winter tyres in Japan can void your insurance in the event of an accident. Even if you are not at fault, the insurer may reduce your payout if your vehicle was not compliant at the time of the incident.
Tread Depth Reality
The legal minimum in Japan is 1.6 mm, but tyre performance drops sharply below 3.0 mm. Replacing tyres before they hit the legal limit gives you a meaningful safety margin on wet or icy roads.
