Our approach

We recognize that in order for the Yakult Group to continue growing sustainably, we need to not only further promote product development through the pursuit of excellence in life science but also create services that provide new value. Yakult 1000 (launched in 2019) and Y1000 (launched in 2021) are drinks that help resolve stress-related issues in contemporary society and have become hit products. While bearing in mind the views of our stakeholders, we will continue to further develop our organizations and create frameworks to generate innovations that will help resolve social issues and bring about our evolution toward a healthcare company.

Founded on innovation

Yakult’s history was built on innovation. In the time of Yakult’s founder, Minoru Shirota, unsanitary conditions in Japan caused large numbers of children to die of infectious diseases. Concerned about these conditions, Shirota set his sights on the field of preventive medicine, which aims to help people avoid sickness rather than treating diseases after they occur, and started down the path of microorganism research. This resulted in the creation of Lactobacillus casei strain Shirota,* commercialized as a fermented milk drink called Yakult. At a time when little attention was paid to preventive medicine and habitual ingestion of Lactobacillus was unheard of, this brought significant change to society. Yakult was thus born of innovative research and technology, making it a product that truly embodies innovation.

Innovation in response to consumer needs

Some 90 years have passed since the birth of Yakult. Consumer lifestyles and values have changed with the times, and Yakult’s expansion into new countries and regions has resulted in a diversification of customer needs. People depend on us to recognize those needs and deliver value that only we can. To create this unique value, innovation is essential. For example, increasing the density of Lactobacillus casei strain Shirota in products like our Yakult 1000 and Y1000 drinks let us provide new value by addressing issues involving stress and sleep, which have recently emerged as serious health concerns. As another example, in 2023, we recognized a rising trend toward viewing pets as family members and formed a capital and business alliance with Japan Pet Communications Co., Ltd. to launch supplements for dogs as jointly created products using unique materials that only Yakult can provide. Constant pursuit of new ideas and technologies and delivery of next-generation products and services like these are essential if we are to adapt to constantly changing market conditions and grow sustainably. We are confident that endeavors like this are what will permit us to continue responding to customer needs and resolving issues.
Nor does innovation end with product and service development. Our delivery system, with its widely recognized teams of “Yakult Ladies,” was an innovative sales approach conceived at a time when women’s participation in the workforce was not as advanced as today. That sales system has continued to evolve with the times, resulting in recent developments like Yakult Delivery Net, which allows people to order items over the internet for delivery by Yakult Ladies, and Yakult Family Delivery Net, which allows customers to order product deliveries to family members living far away.

Cultivating an innovation-friendly corporate culture

To achieve even greater global development, innovation is essential. We believe that this innovation will arise from creative thinking by each and every individual employee. Accordingly, in fiscal 2023 we launched a new Innovative Thinking Skills Acquisition Training course to foster human resources capable of innovative thought that creates new value. The program encourages employees from divisions across the Company to exchange opinions freely, helping participants to break free from the fixed ideas they adhere to both as individuals and as members of their division and consider the interests of the Company as a whole. We will continue offering these opportunities to large numbers of employees and using the ideas they freely produce as the driving force of our innovation.
Yakult also looks outside its company boundaries with initiatives addressing a range of social issues. Here, too, we proactively coordinate with external stakeholders and perform research in relationships of mutual support with external research organizations. By collaborating with partners who have differing viewpoints and specialist knowledge, we will spark innovation and create new business models that also resolve social issues.

Creating value by building affinity

The Yakult Group believes that “in order for people to be healthy, everything around them must also be healthy,” and innovation is an important method for realizing this vision. We will continue to build consumer affinity, understand the needs and challenges people face as individuals and offer solutions accordingly in order to contribute to healthier, happier lifestyles for people around the world.

Main initiatives

Advancing bacteriology research for human health

The pillar of our activities at the Yakult Central Institute is research into intestinal microbiota and probiotics*1 from the perspective of preventive medicine. We are studying the difference between the intestinal microbiota of people in different countries and determining the relationship between the intestinal microbiota and disease in an effort to contribute to better health. For example, our research confirmed that regular consumption of beverages containing Lactobacillus casei strain Shirota*2 helps relieve stress and improve sleep quality for people under temporary mental stress. These findings led to the launching of the fermented milk drink Yakult 1000, which contains 100 billion Lactobacillus casei strain Shirota per 100 ml bottle. And in 2021, we launched Y1000 for in-store sales.

Engaging in joint research with outside research institutions

Joint research with JAXA

In joint research with the Japan Aerospace Exploration Agency (JAXA) we have scientifically verified the effects of the regular intake of probiotics (Lactobacillus casei strain Shirota) on the immune functions and intestinal environment of astronauts on long-term stays aboard the International Space Station (ISS). Before carrying out this research in space, we confirmed that Lactobacillus casei strain Shirota maintains its probiotic properties after long-term storage in a space environment.

Joint research with the National Center for Geriatrics and Gerontology

We participate in the “Higashiura Consortium,” a long-term epidemiological research project launched in 2023 by the National Center for Geriatrics and Gerontology, engaging in collaborative research to clarify what role lactic acid bacteria consumption plays in neurological and physical health in older people. This collaborative research is expected to run until the end of fiscal 2027, and the information obtained during this period will be used to clarify the physiological value of lactic acid bacteria consumption from the standpoint of preventive medicine.

Innovative training

Our long-term vision, as elucidated in the Yakult Group Global Vision 2030, is to “Evolve into a healthcare company that continues contributing to people’s health around the world.” We aim to further promote product development through the pursuit of excellence in life science and create services that provide new value.
In order to foster human resources capable of innovative thought that creates new value, in fiscal 2023 we launched a new Innovative Thinking Skills Acquisition Training course. The course, attended by 112 employees in its first year, aimed to help attendees acquire the abilities and knowledge needed for innovation. Its content included not only lectures but also group work designed to help individual attendees break free of fixed preconceptions in seeking solutions to customer needs. In the last of five sessions (taking five days in all), each group made a presentation about their results, based on the shared theme “Proposing a product or service that Yakult should offer society in response to changing times.” We are confident that continuing to cultivate our human resources through this course will lead to the acquisition of innovative thinking skills and the creation of even more new value.
