FRED shows housing prices in aggregate rising in Japan

If a growing region is declining, I would expect building to be outpacing growth, or a cultural trend away from wanting to own (reduction in demand for purchasing despite growing population)

All that would mean is its a market where supply >= demand. The weights on the scale aren't as relevant, IMO.
