Dr. Shirota decided to put the lactic acid bacteria he discovered in a milk drink easy to metabolize and to drink. He named it Yakult. This name comes from “jahurto” which in Esperanto means yogurt. At the time of Dr. Shirota, it was believed that this new language could have been an international one common among all peoples. The choice of this name, written in Western characters since the beginning, shows the forefront cosmopolitan approach of the Yakult’s “father” who, in his vision, wished the product distributed in all the world. The first bottle of Yakult was made of glass and had a lengthened shape.
