I actually looked into that property once; there was no way it was going to happen for a number of reasons. I ended up buying a house in much better condition in another area.
I really need to do a video about the topic or something. There are many, many landmines with stuff like this. For a very TL;DR and assuming every single other thing is perfect: owning a home does not give you the right to spend any extra time in Japan nor grant a visa; you are on the hook for taxes, fees, septic maintenance (though the above property may have been a pit toilet; I don't remember), and other bills which will have to be paid from a Japanese bank account. There are also certain neighborhood association obligations, property maintenance, fire control, etc.
