I'm looking to get a working holiday visa and move to Japan for a year and travel across the country. My current plan is to buy a van and modify it into a camper and drive everywhere, as I prefer driving to public transport and I mostly intend to avoid all major cities and focus on discovering things off the beaten path.
However I have seen through research that it may be quite difficult for me to purchase a car of any kind in Japan, due to the needs of a residential address for the Parking Certificate (which I won't need, seeing as I'll be living in the Van, parking in rest stops and rural car parks). I was wondering if there was any known "work around" or loop holes or anything that could help me in this endeavor?
(also the reason I want to purchase a Van rather than hire one is that over a course of a year it'll be far FAR more cost effective)
