There are 5.600.000 vending machines in Japan (Source), there is a machine every 22 Japanese!. Is the country with more vending machines in the world, even more than China that has 10 times more population.
There are all kinds of vending machines in Japan, with TV screens, with gambling games, with mobile phone interaction… Some weeks ago I saw a new model that has an interactive map, so you can check restaurants/shops around the place while buying a drink. Nice business model.
