Demand for condominiums in Osaka is growing among family households as well as the wealthy, with the increasing supply of affordable properties a stark contrast to falling demand in central Tokyo.

The number of new condos listed for sale in the city of Osaka, excluding single-room units provided as investment property, rose 6.4 percent to 5,336 units in 2016, the second straight year of increase, according to data by the Haseko Research Institute.

The unit price in the city averaged ¥45.69 million ($407,000), 31 percent lower than ¥66.29 million in the 23 wards of Tokyo, where supply dropped 20.1 percent to 14,764 units — the lowest in a decade, the data showed.
