As trends shift in Japan, the concept of "Everyone's Landlord" or communal property ownership, is heading towards an effective end. This change is fueled by numerous factors, including demographic shifts, cultural preferences, economic realities, and regulatory changes. Resulting in radical shifts in the Japanese housing market, sparking debates on housing policies and affordability.

In Japan, communal property ownership was previously a common way to manage properties, particularly in urban areas. However, due to Japan's population decrease, the aging society, and the increase in vacant houses, preference towards such ownership structure is fading. The economic burden for individual homeowners and complex inheritance laws have also contributed to this shift.

In contrast, the US and EU usually see property ownership as an individual or family affair. While cooperative housing arrangements do exist, they're typically not as widespread. The issues faced in Japan, such as aging population and declining birthrate, although prevalent in certain parts of the US and EU, aren't as severe and therefore property vacancy isn't as large an issue.
