"The 1.15-square-kilometer (0.44 sq mi) palace grounds and gardens are built on the site of the old Edo Castle. During the height of the 1980s Japanese property bubble, the value of the palace grounds was held by some to be more than that of all the real estate in the U.S. state of California."

I do appreciate there are fundamental differences between the US and Japanese economies however from a valuation perspective.
