Yakult History and Timeline

When Dr. Minoru Shirota (1899 – 1982) began investigating Lactic Acid Bacteria, living standards in Japan were substandard due to malnutrition and poor sanitation, which resulted in a range of digestive disorders and general ill health.

Dr. Shirota became convinced that beneficial bacteria were the key to a long and healthy life; with the potential to improve health standards. His determination led to a breakthrough in 1930, when he successfully researched a unique lactic acid bacterium with the ability to survive the acidic conditions of the stomach. The bacterium was named the Lacticaseibacillus paracasei Shirota strain in honour of his research.

Dr. Shirota developed a fermented, milk-based drink to deliver the Lacticaseibacillus paracasei Shirota strain to the gut and named it ‘Yakult’, creating the world’s first commercial probiotic drink.

Dr. Shirota based his work on three principles simply referred as Shirota-ism:

Business commenced in 1935 and Yakult was produced and marketed all over Japan. In 1955, Dr Shirota founded Yakult Honsha Co. Ltd., which consolidated the business and took control of all operations.

Since then, the Yakult group has continued to expand worldwide and today embraces nearly 200 companies in over 30 countries and territories. The parent company Yakult Honsha Co., Ltd. is involved in the research, development and manufacture of a variety of products including pharmaceutical, skin care, foods and other beverages containing beneficial bacteria.

"More than 40 million people enjoy Yakult daily
