Vending machine

If you are in Japan, can see vending machine in everywhere.

A vending machine provides snacks, beverages, and other products to consumers without a cashier. Items sold via these machines vary by country and region.
In some countries, merchants may sell alcoholic beverages such as beer through vending machines, while other countries do not allow this practice (usually because of dram shop laws).

Cigarettes were commonly sold in the Japan through these machines, but this practice is increasingly rare due to concerns about underaged buyers. Sometimes a pass has to be inserted in the machine to prove one's age. In some countries like Germany and USA, by contrast, cigarette machines are still common. Vending machines were used at airports from the 1950s well into the 1970s to sell life insurance policies covering death in the event that the buyer's flight crashed. Such policies were quite profitable, because the risk of any given flight crashing was (and remains) very low, but this practice gradually disappeared due to the tendency of American courts to strictly construe such policies against their sellers, such as Mutual of Omaha.
