Wow! Thankyou for all your replies - some great advice. Cant believe it hasn't even been 24 hours and we have all these responses - we weren't expecting even one!
To fill you in a bit more we are living in Hakuba and will be taking a forced work break for a possible 8 weeks (Hakuba without snow isnt as popular!).
We dont have to worry about a parking space as we have one assigned to our apartment - we were told that this only applies to the bigger cities of Japan? In response, yes, we are planning on sleeping in the back of the car and taking the local roads to avoid tolls and experience it all. We will be using onsens along the way to 'shower'.
As for getting ourselves an inkan - after figuring out exactly what this was, although difficult, this shouldnt be a problem.
We are wondering peoples opinions on shaken - we will be in Japan most likely til mid 2008, so we have two options:
1 - Buy a cheap van (approx. 100 000 yen) without shaken, pay for shaken (approx. 100 000yen) once finished with the van, sell it with around 18 months shaken on it and possibly make the money back therefore being able to buy again if our plans lead that way.
2 - Buy a van with a small amount of shaken, as suggessted, and take it to the junkyard afterwards.
Any opinions on all the above?
Thanks again for all your replies
