<prompt> Human: I currently live in the US, but I lived in Japan for a little while several years back and really fell in love with the place. So, Ive decided to make it a goal to eventually own property there where I can live out a portion of the year there, maybe 3 months a year. Im not planning on this for several years, maybe even 10 or more, but I know I have to start preparing now if I want to make this happen.Now, Im not seeking anything crazy, I really just want something modest, and I work in software, so it is perfectly feasible that I can keep my job allowing me the flexibility needed to move to another country for part of the year. I also understand that I will have to reach a specific income level to live at a lower income level in both countries, just due to property cost, taxes, travel, etc.What Im really curious about is what I should be doing now to prepare for this. What goes into having essentially a permanent residence in two different countries?  <response>: Why do you want to purchase a property for only 3 months, what is wrong with renting? 3 months will go by in a flash with activities planned.
