I get it. That's part of the reason we live AND work in the 'burbs (out near IAD, instead of inside 495). We were very purposeful about where we bought - balance of cost, location, etc. It's doable in most regions (SF/SV and NYC being notable exceptions).

And it's why I asked. At least my mental picture of Japan has most people living in very small (by American standards) apartments. That might not be accurate, based on other comments - with many people commuting 2+ hours each direction (which seems completely bonkers to me). Either way, the average size of a home in Japan is smaller than the US (though I have no idea how it compares to Europe).
