In China, many people invest their money in properties. So, you would have a well-off household owns more and more apartments just for safekeeping. I would imagine it's a good opportunity for AirBnB type of services to thrive. At the same time, a lot of Chinese are quite distrusting of unknown person for good reasons. Renting out their own place with all their belongings can just be asking for trouble.

Japan on another hand, might be doing a better job welcoming guest to stay over their own home. I wouldn't know though.
