Japanese vending machines are amazing. You can get almost anything from them, of course your regular juices and your drinks but here in Japan we can also get beer and Japanese sake. Yes even without proof of ID. It is quite amazing and surprising to most non-Japanese visitors that you can just walk up to any vending machine and grab a beer.
There are vending machines that you can buy eggs, newspapers, Japanese food and even ice cream. My friend actually bought a vending machine and makes crapes and puts them in bottles and sells them. He makes about $5000 a month off of sellong crêpes out of a vending machine.
