As of my last knowledge update in January 2022, Japan is known for having one of the highest numbers of vending machines per capita in the world. Japan's vending machines are incredibly diverse, offering a wide range of products, including beverages, snacks, cigarettes, electronics, toys, clothing, and more. The convenience and prevalence of vending machines have made them a common sight throughout the country, serving both locals and tourists. However, please note that the number of vending machines in a country can change over time, so it's advisable to consult more recent sources or statistics for the most up-to-date information on this topic.
