Before you go
If you plan to ski Japan by camper van, read this first. These sections cover what’s normal on the ground and what makes winter van travel work.
Camper culture in Japan
A lot of Japanese skiers sleep in their cars on winter weekends, so doing the same never feels out of place. Between the 24-hour restrooms, vending machines, parking areas, and the fact that many resorts allow overnight stays, traveling by camper van just works. And even when a resort doesn’t offer overnight parking, there’s almost always a konbini close by where people quietly sleep in their cars without it being a big deal.
Where and what to rent
Campers can be rented in major cities near ski regions, like Tokyo, Nagano and Sapporo. In winter, the van must have snow tires (checkpoints are common during storms) and I also recommend to get a 4WD van. A diesel heater in the van is required, as temperatures drop well below freezing at night (I've seen -15°C in Hokkaido!).
Driving in Japan
Foreign visitors need an International Driving Permit to rent and drive in Japan and rental companies will not release a vehicle without one (these permits must be renewed yearly!). International Driving Permit do not replace your driver license. You must carry both of them(as well as your passport). I also recommend to get an ETC card (often provided by the rental company), as it allows seamless use of Japan’s toll roads and makes driving much easier. Japan drives on the left side of the road, which can feel intimidating at first, you'll get used to it.
Camping etiquette
Overnight parking in Japan follows clear, unwritten rules. Parking lots are not campsites: no chairs or tables outside, no cooking in parking lots, no music, lights kept off once it gets late, and avoid idling whenever possible.
Trash is always your responsibility, carry it with you until you can dispose of it properly (Best way to do it is at the konbinis) and remember that parking lots are workspaces first, used for snow removal, staff access, and morning setup. When these expectations are respected, overnight parking fits naturally into how resorts already operate.
