Many thanks again for everyones replies, turns out there is an AOPA in Japan, (should really have been my first port of call, but in my defence I'm not the brightest). I will contact them as well as the individuals and companies that Runway101 has kindly supplied. Hopefully I will have something sorted for when we come over here again later this year, but at $800 an hour it will be a very short trip.
As I find out more information I will post it, cheers.
