Consider this for a second trip. The trains reach the cities; the grassland, the caldera rims and the coast roads are an hour beyond the last station. Three routes, RV Parks and hotels every night.
The trains here are excellent and they reach the cities, the temples and the hot-spring towns. What they do not reach is open country — an hour or two beyond the last station, on roads with almost nothing on them.
A campervan turns those roads into the trip itself. You sleep where you stopped, you carry your luggage with you, you cook when you want to, and the drive between two places stops being the dull part of the day. For a family it solves more than that: children sleep in the back, the bags stay in the vehicle, and you are not tied to a hotel booking made four months ago.
Kyushu — volcanoes, grassland and hot springs, seven nights. Kanto — mountains, lakes and highland, five nights, starting from Tokyo. Hokkaido — the one to aim for, nine nights, June to September.
The three routes stay out of the big cities. City sightseeing works better by train, and a large vehicle in central Tokyo or Fukuoka is a parking problem rather than a holiday. Use the trains for the cities and the van for the country.
Book RV Parks for the driving nights and a hotel every third night. That is the pattern that works: the parks give you the freedom and the position, and the hotel gives you a bath, a bed and a washing machine.
These are paid overnight sites certified by the Japan RV Association. There were 588 of them across the country as of November 2025. Most are attached to something useful — a bath house, an inn, a farm shop.
Book the hotel nights in advance and put them where the route allows a rest. A proper bath, a bed that does not fold away, and somewhere to wash clothes change the second half of a long trip completely.
Families with young children: make it every second night. It is the difference between a holiday and an endurance test.
Volcanoes, grassland and hot springs. A grassland highway across the Kuju range, the Aso caldera at dawn, a gorge you row into, and a ferry crossing with the van on board.
Mountains, lakes and highland, starting from Tokyo. Cedar forest at Nikko, a boardwalk across a marsh at 1,400 metres, a hot-spring town, and Mt. Fuji from a lake.
The one to aim for. Wide straight roads, few signals, lavender in July, a caldera lake under mist, and a coast where the forest reaches the sea.
A place can be better known than the prefecture it sits in. Use the prefecture pages below to work out where to eat, where to stay, how to get around and who to call.
