For a long time, people have believed that a healthy intestinal tract leads to a long life. That was also the belief of our company's founder, Dr. Minoru Shirota, who aimed to create a product to maintain overall health and wellness. Today, he is accredited with creating the world's first probiotic shot drink, Yakult! With billions of live, active bacteria and the exclusive probiotic strain Lactobacillus casei Shirota, Yakult works by reducing the chances of bad bacteria taking over. Probiotics are not alike, as they vary by genus, species and strain. Scientific studies have proven that strains of Lactobacillus casei, which Yakult contains, have a positive effect on the digestive system.

But that wasn't all. Dr. Shirota's approach to health was revolutionary, too. It is known as preventive medicine - Exercising, eating healthy and consuming probiotics daily are ways to help maintain good health. Consuming Yakult daily is a great way to incorporate probiotics into your health routine!

Dr. Shirota envisioned that everybody in the world would be able to enjoy the benefits of Yakult! That is why our company strives to offer Yakult at a price anyone can afford.

Yakult pushes forward with the quest for new possibilities for probiotics in the academic and medical fields. We work with doctors, scientists and dietitians worldwide to help people with medical conditions and find ways our probiotics can be used to help people suffering. Yakult's research has led to many significant medical advances, even beyond the probiotics field, such as the development of the Campto Injection, the first-line drug for colon cancer in the United States.

The human digestive system has over 500 types of bacteria, most of which are good and keep you healthy. A healthy person has more good than bad bacteria, but any change in the body’s bacteria balance can cause digestive issues. With probiotics, the good bacteria help reduce the possibility of bad bacteria taking over. By doing so, probiotics may help balance the digestive system and improve overall wellness.

The Yakult Company started the probiotics revolution by introducing Yakult in Japan in 1935. Today, Yakult is the world's leading probiotic beverage. Why? Our product speaks for itself. Once you experience the delicious taste and health benefits of Yakult, you'll have no doubt why it is loved by millions of people around the globe!

In the 1930's while studying microbiology at the Medical School of Kyoto University, Dr. Minoru Shirota adopted the philosophy that intestinal health leads to a long life and set out to find certain lactic acid bacteria that could help fight harmful bacteria in the body. At this point in history, health care was expensive and many people lost their lives to infectious diseases caused by poor nutrition.

During his research, Dr. Shirota cultured a bacterial strain that was strong enough to survive harsh acids of the stomach and reach the intestines alive where they could have a beneficial effect on the body. The probiotic strain was named Lactobacillus casei Shirota in his honor!

Thinking of a way that people would be motivated to ingest probiotics every day and be spared from suffering and disease, Dr. Shirota had the brilliant idea to pair the "friendly bacteria" with a delicious flavorful mixture that everyone would want to drink every day.

In 1935, he manufactured this drink for the Japanese market as "Yakult," which was derived from the word "yogurt" in Esperanto, the proposed universal language of the 1880s.

Fortunately, Dr. Shirota had a good sense for a product that many would enjoy. In fact, Yakult was such a great success that in 1955 The Yakult Honsha Co., Ltd., Yakult's national headquarters, was formed with Dr. Shirota as its founder.

Today, Dr. Shirota's philosophy, known as Shirota-ism is the core and driving force behind all of our company's activities and Yakult has become the universal probiotic drink loved by people around the world!
