I'd like to take you up on the offer for the forms. Tokyo is getting old, and I find the city quite depressing; wouldn't mind spending some time in the country side. Are you in Japan at the moment?
My brother has been living in China on short term tourist visas for close to 5 years. In the mean time he has built and sold one (non-technology) business and claims not to feel worried about the possibility that one day they will stop letting him back in despite substantial real assets in the country.
I'd been considering it, but in my case everything I own is easy to transport across borders :-)
