Contribution to Extending Healthy Life Expectancy
Our Approach to Extending Healthy Life Expectancy
Extending healthy life expectancy refers to the period during which daily life is not restricted by health problems.
To live a healthy and active life, it is important to be mindful of the three pillars of nutrition, physical activity, and social participation, and incorporate them in a balanced manner.
These are important points that apply to all generations. Incorporating several of these into your daily routine will help achieve a healthy lifestyle.
In recent years, issues related to food and health have become more diverse, and extending healthy life expectancy has become a major issue in Japan. Efforts to prevent metabolic syndrome, combat frailty, reduce the risk of dementia, and strengthen the immune system are gaining attention as ways to maintain lifelong health.
The Kewpie Group will contribute to extending healthy life expectancy by encouraging eating habits that support individual long-term health at each life stage and promoting initiatives that improve people’s quality of life.



Efforts to Increase Salad Consumption
Salad First Project
Vegetables are essential for a healthy diet. However, vegetable intake is chronically insufficient in Japan.
Additionally, the number of dishes on the dinner table is decreasing, especially among younger generations. With busy schedules, meals are simplified and vegetables are not given priority.
To solve this problem, rather than forcing oneself to eat only vegetables, we propose a plan called “With Vegetables” whereby vegetables are incorporated into the diet in a way that suits individual lifestyles and preferences.
Rather than eating vegetables out of a sense of compulsion, we aim to encourage people to adopt a diet that naturally increases vegetable intake by encouraging positive thoughts such as “eating vegetables makes me feel more energetic,” which in turn will motivate behavioral changes.
As a leading salad company, we will collaborate with businesses engaged in home dining, readymade foods, and restaurants to pursue the infinite possibilities of salad.
In FY2025, we will promote proposals combining protein sources and vegetables under the theme “Protein with Vegetables,” and through the proposal of different meal ideas such as power salads and other satisfying, single-plate menus, we will contribute to resolving the issue of low vegetable consumption.


What you like, how you like it, when you like it.
With Vegetables

No one cares more about salads than the Kewpie Group. We want to demonstrate the value of salads through the provision of delicious salads.
With this in mind, in 2023, we launched the “Salad First” campaign to strengthen efforts aimed at conveying the appeal of salads.
Raising Awareness of the Importance of Chewing
Salads enable us to eat plenty of vegetables, and require thorough chewing. It is well known that the more fiber one eats, the more chewing is required.
The ability to chew is very important for people to enjoy meals throughout life. However, the act of chewing is done semi-unconsciously, and it is difficult for people who have acquired the habit of not chewing to consciously improve it. Kewpie is engaged in joint research with Lotte Co., Ltd. and Wayo Women’s University to raise awareness of the importance of chewing. In 2022, we published a ranking table (in Japanese) that summarizes the results of our joint research on the number of chews typically done for each type of food.
Health-Focused Products
The Kewpie Group has historically worked to spread what was then a new food culture of eating vegetables as salads. As such, the company grew hand-in-hand with the expansion of salad menus. Going forward, we will continue to research and develop products so that we can contribute to the diet and health of all generations as everyone's dietary partner.

Adding Value to Eggs
Since Kewpie’s founding, we have continuously explored the infinite possibilities of eggs. We have discovered valuable functions hidden in every part of the egg, from egg yolks and egg whites, to shells and eggshell membranes, and have used these discoveries to develop innovative products.
We will contribute to the health and well-being of our customers through R&D aimed at maximizing the potential of eggs, as we continue to create new value for eggs and lead innovation in the food industry.
Egg Allergy Research
Research into Allergen-Reduced Eggs
Kewpie and Hiroshima University have conducted joint research into allergen-reduced eggs* since 2013 with the hope of reducing to zero the number of people who suffer from egg allergies. Allergen-reduced eggs are produced using genome editing technology to target and disable ovomucoid activity in chicken eggs, then allowing the hatched chicks to grow, mate, and lay allergen-reduced eggs.
Since FY2022, we have participated in the national Program on Open Innovation Platforms for Industry-academia Co-creation (full-scale COI-NEXT), and will further advance applied research with Hiroshima University, with whom we have worked thus far, as well as partner companies and other new colleagues.
By expanding food options, we will continue taking on the challenge of delivering the great taste and health benefits of eggs to people with egg allergies.

Methodology to produce chicken eggs that do not contain ovomucoid
*Chicken eggs that can reduce allergies through the removal of heat-resistant proteins and digestive enzymes from the eggs.
Egg Allergy Prevention through Eating
Food allergies cause reactions such as hives and breathing difficulties, and egg allergy is thought to be especially common in babies. Previously it was thought that consumption of foods causing allergies should be avoided, but recent research* has revealed that starting to feed babies small amounts soon after they are weaned is an effective way of preventing the onset of allergies.
The Kewpie Group is working with specialist medical institutions to study ways of using less allergenic eggs created by heating, etc. and linking their use to safer diagnosis, treatment, and prevention of egg allergy. We will continue to support the discovery of new methods for diagnosis, treatment, and prevention.

*In 2016, the National Center for Child Health and Development presented the results of research on egg allergy prevention. A study of 121 infants suffering from atopic dermatitis showed that with proper skin treatment, the incidence of egg allergy at one year of age in babies that ate small quantities of powder made with heat-treated eggs from the age of six months was 8%, compared to 38% for babies that did not eat the powder, demonstrating the effectiveness of this technique.
Effect of Hen's Egg Intake on Cognitive Function

We applied for the "FY2021 Innovation Creation Enhancement Research Promotion Project"*1 offered by the Bio-oriented Technology Research Advancement Institution (hereafter "BRAIN"), and the project was awarded*2 under the title of "Research on hen's eggs' ability to improve cognitive function and development of value-added hen's eggs to expand the egg market." In the "Applied Research Stage" and alongside five other institutes,*3 Kewpie aims to clarify the effects of hen's eggs on cognitive function and jointly develop value-added eggs that contain high levels of these functional ingredients. The purpose of this project is to clarify the "cognitive function improvement effect" of hen's egg intake, to identify the components involved in this improvement, and to confirm the effect in human studies.

Egg-Free Mayonnaise-Type Condiments
In spring 2014, to cater to students with egg allergies Kewpie launched an egg-free mayonnaise-style condiment for commercial use in school meals. After it went on sale, we perceived a growing household need for such products and in February 2015 we launched an egg-free mayonnaise-type condiment on the consumer market. We will continue contributing to better diets by creating products that society needs.

Tamago (Egg) Star In-house Certification System
In FY2019, we started the internal certification program "Tamago Star."
We will increase the number of people across the entire Kewpie Group who can talk about eggs, and we are aiming to become the "Leading Company for Eggs."
Tamago Star is accredited to those who have attended a study session for correctly communicating knowledge about eggs and have acquired 3-Star Tamarie certification (Nihon RangyoKyokai Association).
Going forward, those accredited will take on the role of awareness-raising activities to communicate the appeal of eggs, both inside and outside the company.

Tamago Star certificate
Egg White Paper
Conducted since 2017, the "Egg White Paper" is a research report analyzing perceptions, eating styles, and trends regarding eggs. We use the results of the questionnaire on what people find attractive about eggs and their favorite egg dishes to cultivate accurate knowledge about eggs and suggest ways to enjoy egg dishes.

Collaboration and Research to Extend Healthy Life Expectancy
Frailty Prevention Initiatives

Joint Research with the University of Tokyo Institute of Gerontology (IOG)
We are conducting joint research with the IOG into the relationship between vegetable and egg intake, and the eating habits and physical functions of older people.
Participating in the Frailty Prevention Promotion Council and Establishing Industry Associations
We participate in the Frailty Prevention Promotion Council, established in 2024, and promote public and private sector collaboration in raising awareness about and promoting frailty prevention. Further, in April 2025, the Frailty Prevention Services Promotion Association was established to promote frailty prevention services. This new industry group comprises 10 companies, mainly distributors and processed food manufacturers, who aim to foster the healthy development of the frailty prevention industry.
Supporting Health Through Diet and Exercise
We are working together with Central Sports Co., Ltd., who share our belief in the importance of nutrition, physical activity, and social participation as three key elements of lifelong health.
We communicate the importance of nutrition and exercise through Central Sports dietary education events and the Kewpie website, so that everyone from children to older people can live a healthy life.

Sharing Useful Information for Healthy Dietary Lifestyles through a Joint Project
We launched a joint project called Salad and Egg Recipes and Healthy Kitchen with the ABC Cooking Studio, which shares our desire to contribute to healthy dietary lifestyles. In response to dietary issues such as a lack of vegetables and protein, and excess salt, the two companies leverage their respective strengths and expertise to provide information on healthy dietary lifestyles related to salads and eggs, through web content and one-day lessons.
In March 2023, we published a Report on Salad and Egg Recipes and Health 2023, which summarizes our research on health awareness and concerns, and issues when preparing salad and egg dishes.

Cooperation with the Shokuryo Gakuin


Class scene
In cooperation with the school, a training school for nutritionists and culinary professionals, we offer lectures and classes for the students.
We conduct classes promoting awareness of the value and appeal of salads and eggs, as well as provide students with fun learning opportunities that include hands-on activities at the Vegetable Friends' Farm in Fukaya Terrace Park.
Encouraging Eating Habits that Support Health
Lecture Events Themed on Food
Communicating correct information about food and the importance and joy of food is one of our most crucial roles.
In our hope to contribute to healthy and enjoyable dietary habits, we send employees out to give lectures themed on food that provide correct information on diet and health.
We currently have three different programs; "The Appeal of Vegetables" features content designed to stimulate interest in those who attend by watching DVDs on vegetable nutrition and ideal intake as well as showing cooking methods that participants can put into practice in their everyday lives.
We've received comments such as, "I'll plan my meals with 350g of vegetables per day in mind," or "I learned about the broad appeal of vegetables and how to enjoy them at the dinner table," indicating that this program conveys the appeal of vegetables.
Nursing Care Events
In 1998, Kewpie released Japan's first retail nursing care foods. Japan became the world's first super-aged society and the need for nursing care foods continues to rise.
We hold study sessions with professionals involved in the nursing care field as well as students to facilitate greater understanding of foods for the elderly and universal design foods.
Food and Health Awareness Activities in China
As health consciousness is growing in China, Kewpie China (rendered 丘比 in Chinese), which aims to contribute to diets and health in China, is conducting health promotion activities across the country in collaboration with food science societies and other organizations, utilizing research results from both Japan and China.
We also maintain efforts in the produce sections of stores to raise awareness of the health functions of vegetables and to draw attention to salads. We are expanding these activities from Beijing, Shanghai, and Guangzhou, to the rest of the country.

Food and Health Awareness Activities (Shanghai)
Taking on Challenges in the Wellness Domain
Development Leveraging the Group’s Unique Strengths
In addition to eggs, which are the main ingredient in mayonnaise, we have also been conducting research on acetic acid bacteria, which has long been used to make vinegar. Egg yolk choline is expected to help maintain cognitive function, while acetic acid bacteria have been found to alleviate discomfort associated with hay fever symptoms and alcohol consumption, regulate immune balance, and alleviate cold symptoms. Building on the results of many years of research into these and other proprietary materials, the Group will expand its products and services to address four health issues: Metabolic syndrome, frailty, dementia, and immunity.
Furthermore, we will utilize new sales methods such as D2C and cross-border e-commerce to deliver our health-promoting products to even more customers.
We will also take on challenges in fields other than food, such as medical device development and licensing businesses, contributing to the promotion of greater health and a better quality of life for our customers.
Gluconacetobacter Hansenii GK-1
The Kewpie Group creates Nigori Vinegar (cloudy vinegar) using a proprietary production process, and is conducting research focused on the functions of Gluconacetobacter Hansenii GK-1, a unique ingredient used to make this vinegar, which we will link to the creation of new value.
Previous studies have confirmed in human clinical trials that acetic acid bacteria GK-1 reduces nasal discomfort caused by pollen and house dust. They also confirmed that Gluconacetobacter Hansenii GK-1 increased the amount of secretory IgA in saliva, and reduced various symptoms associated with colds. These results suggest a correlation between the effects of acetic acid bacteria and allergy symptoms. We will continue this research going forward, and plan to collaborate with external parties to provide acetic acid bacteria for use in products, and as an ingredient.

Initiatives Toward Pre-Symptomatic Illnesses (Cancer Prevention)
In 2013, Kewpie began research into the prevention of cancer through diet. In 2019, we commenced joint research with Yokohama National University and Tokyo Medical University to determine future cancer risks. By measuring a component called microRNA present in blood, we aim to determine future cancer risks and prevent disease through dietary recommendations that improve microRNA expression.
The Technology Development Project on Next-Generation Artificial Intelligence Evolving Together with Humans (2020–2024) led by the New Energy and Industrial Technology Development Organization (NEDO) has concluded, and at present, we are promoting additional research aimed at commercialization.

Initiatives in Medicine
Kewpie's fine chemicals business provides a variety of food, cosmetics, and pharmaceutical products, including the acetic acid bacteria enzymes created as a result of our vinegar-related research as well as egg yolk lecithin and lysozyme. Researched for over 30 years, hyaluronic acid is a core material in the business, and Kewpie has the largest domestic sales volume according to the 2023 Fuji Economic Survey.
Kewpie is the only manufacturer in Japan that produces hyaluronic acid in two ways; extracting it from the rooster comb and through microbial fermentation. Making use of our strengths in molecular weight control technology and modification technology, we continue to provide technological support to satisfy the needs of our customers.

Kewpie's first medical device is K Smart, a submucosal injectable for endoscopic therapies
Kewpie's hyaluronic acid is used in a variety of pharmaceuticals, including as a material for agents improving joint function, and in medical eye drops. Using the manufacturing and quality control knowhow gained through these initiatives, Kewpie is developing a business focused on the planning and development of medical devices using hyaluronic acid.
Sodium hyaluronate is used in the endoscopic injectable material, which is a medical device used in endoscopic surgeries to remove cancerous lesions discovered at an early stage in the stomach, esophagus and colon before the cancer spreads beyond the mucosal layer of the gastrointestinal tract. The viscosity of the hyaluronic acid helps to separate the mucosal layer from the muscle layer and by maintaining that state assists in either improving detachment or resecting of the lesion. By helping to treat cancer in its early stages through the use of endoscopes, Kewpie is working to extend healthy life expectancy.
Kewpie also offers products that can be used the day before the test by those taking colorectal exams and visiting medical institutions.
