I understand the Japanese don’t like old houses. Homes are regularly torn down and rebuilt. Do some research, but it might not cost as much as in the West to rebuild.
It depends. There are cheap builders here of course, but you really get what you pay for. You’re going to be paying a lot if you want insulation, double-glazed windows (or better), mechanical ventilation, enveloping, etc.
