Japan the home of vending machine
If you were to come ask me about vending machine the first thing I think about is soda, next is Japan. Why Japan? Because I believe Japan have the largest number and types of vending machines in the world. Maybe not the largest number but in toyoko you would see at least one vending machine every street. They even have food canteens that have nothing but vending machines to sell food. In some of their shrines they even use vending machines to sell their talismans. I even come upon a vending machine with cranks that let you catch live seafood. They also have locker like vending machine that sells items like eggs and vegetable. I have to say only Japan sells all these stuff through vending machines.
