Every time I see a camper van like that I take a photo with it - just because it is rare to see them and I love them (this is for my personal collection actually). I have never seen a foreigner driving this kind of RV. They are popular among Japanese though.
I will publish another thread about types of RV`s in Japan.
But if you look at the cars we offer for rent, it will give you the idea what sort of vehicles can be used as Camper vans.
