Many vending machines are owned by beverage companies such as Ito En, Asahi, or Coca Cola, and landowners can enter into a contract with them to place the machine on their land, receiving either a land rental fee or a cut of the profits from drinks sold. Just sticking one in front of your house is like putting a bank box out there for others to deposit money into.
