History/Story of Yakult Probiotic Drink

Yakult was first developed in 1935 by Japanese scientist Dr. Minoru Shirota, who discovered and cultivated the Lactobacillus casei Shirota strain, still used today. The drink quickly gained popularity in Japan and later expanded worldwide as awareness of probiotics and gut health grew.

Yakult U.S.A. established its headquarters and factory in Fountain Valley, California, in 2014, bringing the production of this global health drink closer to American consumers. The factory can produce millions of bottles per day, and the tour highlights both its scientific roots and modern technology.
