When I first visited Japan, I was fascinated by the number of vending machines they have placed on the streets. These vending machines, mainly selling drinks, are virtually everywhere to the point I wondered whether the convenience stores would sell drinks since people can easily buy drinks from those vending machines.
There was once I noticed a special item in one of the machines. I could not understand the Japanese wordings but I thought it would be good to try as I was thirsty. It turned out to be a can of corn soup — and it was warm. Drinking warm soup during winter was such a comfortable feeling.
