In 20-30 years an accommodation loses about 50 to 60% of its value in Japan. The only thing that is stable or gaining any value in Japan is land. The rest is just a deprecating asset.
This is why you buy a fully-depreciated ~40-year-old apartment or house.
I spent my entire life's savings to do this and it was the best decision I ever made. When and if I leave Tokyo, I will rent it out for side income. I can't overstate the peace of mind this gives me.
