Thanks for the comments, very grounded.
Actually you can live quite reasonably in Tokyo if you know the areas but yes accommodation prices can be high for the size. You can get town houses pretty centrally for about half a million which isn't bad because it is so cheap to get a mortgage here...
Watching it from afar, you lot appear to be living under the worst government for quite some time. I certainly ain't motivated to up sticks here and bring my wife and kids over any time soon.
