Are Japanese parking lot investment yields really as high as advertised? Monthly parking has a national median of ¥10,000 (approx. USD 67) and reaches ¥27,549 (approx. USD 184) in central Tokyo — figures drawn from a government price survey, since Japan has no MLS-style database of realized rents.

USD 1,667–2,733) a year because parking lots don't qualify for Japan's residential-land tax discount.
