You can buy most types of real estate even when you are not a Japanese national and not residing in Japan; you can register yourself as the owner of the purchased property as well. There is no program granting a permanent residency-by-investment in Japan. You can be entitled to a permanent residency application after staying in Japan for some years following a proper work-visa status. You can obtain a business manager visa when you start your own business at the same time as investing in real estate.
