Japan. For an island with limited space they treat their real estate market very differently. The land itself has value, but structures depreciate to zero.
Housing prices in Japan have been going up for years. They had the implosion after the superbubble in the 1990s (prices got so ridiculous, that the land beneath the emperor's palace was worth more than all the land in California)
But other than this extreme, the trend has very definitely been up and to the right, year after year after year. Even as the population declines.
