It's natural for us to have many vending machines. Our school's ALTs are surprised .Because there are many vending machines in Japan. When I heard about this, I was surprised. Most students use vending machines everyday. When I want to buy a bread, I always find the bread is sold out. So I think vending machines are not so many.
I asked two international students in this school. One of them, he is from Germany. The other is from Canada. Question; 1,What do you think of many vending machines in Japan? 2,How many vending machines does your school have? Answer; Vending machines are convenient, because if you are thirsty, you find at every corner in Japan a vending machine. So you don't have to look for a stand. And you also don't have to wait very long, like a stand where it can happen that there are a lot of people. Vending machines are quick to get a can and very often the food/drinks in them are cheap.
In Canada, her school has three vending machines. One of them is snacks. Two of them are drinks. There are many vending machines everywhere in Japan.
Last year, "What juice and bread do you like the best?" was researched. Carbonated drink and Cocoa is the best. Chocolate chip melon bread and French bread are the best.
In my school, there were two more vending machines last year. But now there are not. Because vending machines make much Co2, it's bad to us and to the environment.
Vending machines is convenient but we also should think about the world environment.
