Japan has many formal campsites, but booking windows, vehicle-size limits, waste rules and seasonal closures vary by site.
Camper Rules Assistant
Build a country route and get compact allowed/do-not-assume/check cards for overnight rules, LEZ, tolls, documents and winter requirements.
Japan
Japan motorhome travel works best with booked campsites, exact vehicle dimensions, expressway toll planning, ferry or carnet paperwork and careful checks for narrow roads, snow and typhoon-season disruption.
Use campsites, RV parks, michi-no-eki where overnight stays are allowed, private parking or hosted sites rather than assuming roadside camping is acceptable.
Expressway tolls, ETC compatibility, ferries, parking and route choice can dominate the cost of a Japanese motorhome trip. There is no simple national camper low-emission sticker for visitors, but city parking, height limits, local traffic rules and narrow roads need careful routing.
Thailand
Thailand motorhome planning is built around Department of Land Transport permission for foreign vehicles, Thai Customs temporary import, recognised driving documents, official campgrounds or private stops, tollways, national parks and monsoon disruption.
Campground quality and motorhome services vary: many sites are tent-focused, so confirm vehicle access, height, power, water and waste handling.
Use national-park campgrounds, paid campsites, resorts with permission or private hosted stops; do not assume beaches, temples, petrol stations or viewpoints allow overnight camping.
Bangkok-area tollways, bridges, ferries, park entrance fees, campsite charges and temporary-import guarantees should be part of the budget. There is no simple visitor camper sticker that solves city access: traffic density, height limits, parking size, old-town streets and local police rules need route checks.
Documents and insurance
Japan
Visitors must match Japan's foreign-licence rules and, for a private imported vehicle, the customs and carnet or temporary-admission process.
- Japan Customs describes temporary import of private automobiles using a carnet, normally with re-export within the carnet-valid period.
- Carry passport, licence, IDP or Japanese translation where required, vehicle registration, insurance and ferry or customs documents.
Thailand
Foreign vehicles should be handled through the Department of Land Transport Foreign Vehicle Permit process and Thai Customs temporary-import formalities before entry.
- Thailand.go.th guidance points visitors to valid Thai or international driving licences and, where necessary, temporary Thai licences.
- Carry passport, licence or IDP, registration book, insurance, owner authorisation, FVP approval and customs documents.
