It’s true: in Japan, you can get almost anything your heart desires out of a vending machine. There have been reports of Smart car vending machines popping up in Tokyo that do have actual Smarts in them—but those ones are only for display purposes, and all you’ll get out of them are marketing materials to entice you to buy a Smart.
This, too, is an exhibit, and you unfortunately can’t actually get a Toyota from it. It’s part of Toyota’s Megaweb, located in Odaiba, which is a man-made island off the coast of Tokyo that’s a giant theme park in itself.
It’s a good thing this is only an exhibit; imagine your frustration at your newly-purchased car getting stuck in the machine! No way you’d be able to use any “technical tapping” effectively on this one!
