Need to get a good realtor you can trust and contractor too if you want to renovate it ,. Best to take a trusted contractor with you to indict the home too so you know how much you have to spend. Make sure the home is rebuildable and has no restrictions that limit your options. Making an LLC business that holds or manages the house is good to for taxes etc,. Nest houses are about 10-15 minutes away from good train stations that can lead to popular areas for work etc,. For example in Osaka Takaishi or Hagoromo is good suburbs that are convenient with good schools,. Nakano or nakameguro are good in Tokyo but you have to find a house there,. Other option is to live in the countryside but is less convenient ,. Good luck in your search.
