The lowest ownership rate goes to Hokkaido (23%), followed by Okinawa (30%) and Tokyo’s metropolitan area (35%).

Many considered it strange that the northerly island of Hokkaido would have not only a lower ownership rate than the southern island of Okinawa, but the lowest rate of Japan as a whole.
