These properties are outside of Tokyo as a cash flow investment rather than for appreciation.

Blackstone recently bought a 2 billion dollar deal from GE capital in Tokyo mixed use resi and commercial.

Being in Plano, you are going to get a lot more Priuses coming your way and a lot of people probably complaining about the lack of decent sushi and Japanese food in town until some new ones can open up as the area in SoCal where Toyota is like a suburban Little Tokyo. 

You came to the right place.I'm actually an expat Iowan living/working in Tokyo looking to build my portfolio back home as well.

I love traveling (Tokyo, Osaka, Kyoto, Seoul, London, Rye, the Bahamas, majority of U.S.), I enjoy carpentry, and am an avid recreational shooter.

@Jerry Padilla  For "tiny", downtown Tokyo, Japan condos have some great ideas. 

(New York, Tokyo, Hong Kong, London, etc, etc).

I was just in Tokyo this past winter and can confidently say you might enjoy the break from the crowds and stimulations of Tokyo for SF.

Take this for honest feedback and not kicking you while you're down -If estimating accurately was as easy as simple (sqft * $$) you'd rarely see a contractor go out of business and investors would all fly on private jets to eat lunch in Tokyo, dinner in Paris and breakfast in New York.

I'm currently based in Tokyo, and looking into the US Market.
