And if you're in Lyons, CO (not far outside of Boulder) you must check out Lyons Classic Pinball. There are a ton of machines, plus the proprietor is super knowledgable.

Does anyone know of anything like this around Tokyo? I'm visiting in a few weeks and would definitely like to see something like this, aside from regular arcades.

I saw One More Time [1] but that's about 4.5 hours out from Tokyo if my directions are correct.

Portland, OR has a ton of machines all over town. Just found http://www.pinballmap.com, which shows machines in various places around the US.
