This is a transportation system for the Yakult delivery person, who does residential door-to-door delivery of Yakult probiotic yogurt drinks every morning throughout South Korea. Although Yakult beverages can be purchased at grocery stores, many South Koreans prefer to have Yakult delivered to their homes in the same way that milk was delivered to American front doors during much of the 20th century. Each of the thirteen-thousand Yakult delivery people, commonly called "Yakult Ladies," are responsible for delivering to 180 or more homes and offices every morning.
The intention of this transportation system was to help Yakult Ladies, whose ages range from 20 to 60, with the physical challenges they experience during their arduous delivery routine and at the same time, make them feel proud of their association with the Yakult brand and their role in Korean daily life.
