Quizplus · Accepted Answer

Labor is scarce in Japan and vending machines help conserve on labor. In an effort to increase efficiency and reduce labor costs, vending machines have become a common sight across Japan, with over 5 million vending machines in the country. This has been particularly evident in the service industry, where vending machines have replaced human interaction in many instances, such as for buying train tickets or purchasing snacks and drinks.
