Tokyo is much bigger and denser than either one of those yet it has them everywhere. I hope you know that I mean those vertical car lifts which pack many more vehicles than your regular car parks, and which can be relatively easily build underground. But you only need to look at Lisbon - a city which had a monumental problem with parking, and they managed to build dozens of huge underground carparks all over the city, under city squares and such, sometimes 10-15 levels deep.
