π€ Japan's vending machines sell everything, even bugs π
Japan boasts over 2.6 million vending machines, offering items from hot ramen to edible grasshoppers across the country. This massive network serves the population, highlighting the cultural emphasis on speed and instant convenience. The earliest known version dates back to ancient Egypt, while modern machines use embedded computer systems to operate. Payment verification involves electromagnetic and optical sensors for coins, and infrared/UV for paper currency. Dual-temperature machines use insulated compartments and heat-pump systems for efficiency.
