Purchase from a vending machine
From time to time, Japan sometimes is said to be "vending machine heaven" according to tourists. The history of Japanese vending machines is long, and many people are familiar with them since their childhood.
A typical item of a vending machine is "water," but you can enjoy all kinds of drinks, including cold water and tea, soft drinks such as Coca-Cola, hot coffee, and sweet cocoa. In general, cold drinks are often displayed in blue, and hot drinks are often shown in red. Many cold drinks are sold in the summer, and many hot drinks are sold in the winter, etc. It also changes according to the season. Also, as many vending machines are managed by each beverage maker, even if a vending machine is on the platform of one station, if you look at the vending machine next to it, something completely different may be lined up.
The price is about 100 yen for small water and about 160 yen for a big PET bottle; the price is often slightly higher than buying at a convenience store or supermarket. There are an increasing number of items that can be purchased simply by cash or by touching IC cards in transportation systems, called Suica or PASMO.
In addition to beverages, there are vending machines from which you can purchase sweets and mobile chargers and other small items, as well as fresh foods such as vegetables and rice, Japanese sweets and oden, and other sweets and meals. Recently, an entertainment type vending machine has appeared that can sense the cutting edge of Japanese robot technology, such as face authentication for confirming one’s age when selling alcoholic beverages, separating products by people standing in front of them, and so on. Not only can you get items conveniently, but there may be ways to enjoy looking for fun vending machines as one sightseeing activity that is unique to Japan.
