In Japan, vending machines are widely used because of its highly mobile population that prefers to shop on the go on foot or by bicycle. In fact, Japan has the highest number of vending machines per capita, with about one machine for every 23 people. Japanese vending machines stock a much wider variety of items; other than the usual drinks, snacks, liquor and cigarettes, vending machines have been known to carry less conventional items such as toilet paper, rice, eggs, toilet paper, wine and underwear etc.

Vending machines are classified mainly according to the products they carry. Below are just some examples:

* With newspaper vending machines, a customer opens the vending machine and gets a newspaper of his choice. But there is the possibility of thievery if a customer takes more newspapers than paid for.

* Candy vending machines sell candy, gumball, capsule with a small jewelry or toy, or bouncy balls. This type of vending machine is relatively inexpensive, and the gross margins can be quite high -- gumballs, for example, can be purchased in bulk for only 2 cents each but can be sold for 25 cents.

* Soda and snack vending machines are more in demand, as snacks and soda are needed by many locations.

* Vending machines that sell specialized items such as tampons, tissue paper and sanitary napkins in ladies' toilets; and cologne and condoms in men's toilets.
