Jidohanbaiki are Japanese vending machines. There are many, many different types of these machines in daily use in Japan. My experiences with vending machines have come mainly from staying in hotels in the US. From a vending machine in the U.S., I can usually get a variety of soft drinks, gum, candy, or chips. In Japan, the sky is the limit as to what is sold in a vending machine. I have seen batteries, flowers, umbrellas, ice cream, ramen, toys, energy drinks, beer, cigarettes, rice, bait for fishing, cameras, videos, and even rhinoceros beetles all sold from a vending machine or jidohanbaiki.
Let's learn the word for vending machine in Japanese.
The word for vending machine in Japanese is jidohanbaiki 自動販売機.
Let's break that word down and see what it really means-
jido - self operating or automated
hanbai - sell, to sell
ki - a machine
Put it all together and you have an automatic selling machine or vending machine, and I can tell you, Japan has some strange ones.
