Japan has recently seen a rise in the phenomenon of "Local Billion-Dollar Residences" or "Rōkaru Oku Shon", particularly in non-metropolitan areas. This trend signifies the growing wealth of local areas, as more people invest in luxury real estate outside the bustling city centers. Factors such as low interest rates, seeking a quieter life away from crowd, and a boost in remote work culture due to Covid-19 have contributed to this shift.

In Japan, investing in real estate has been traditionally considered an indicator of wealth and success. As remote work culture and better technology rise in Japan, it's more feasible for people to live in luxury residences in less densely populated areas. This social change reflects shifting lifestyle preferences as well as an economic uptick in these regions.

This differs from trends in the US, where luxury properties are predominantly located in established wealthy areas, such as major cities and coastal regions. However, the trend does have parallels with the growing popularity of remote work in the US, which is driving increased real estate investment in rural areas and smaller towns.
