Separate Collaborations with SIRUTASU and Wellmira to Provide Personalized Support for Improving Everyday Dietary Habits Based on Scientific Evidence
TOKYO, Nov 10, 2026 - (JCN Newswire) - Eisai Co., Ltd. (Headquarters: Tokyo, CEO: Haruo Naito, "Eisai") announced today that it will advance initiatives to support improvements in dietary habits and behavioral change tailored to each individual, in separate collaborations with SIRUTASU Inc. (Headquarters: Tokyo, "SIRUTASU") and Wellmira Inc. (Headquarters: Tokyo, "Wellmira"). The initiatives will leverage insights from the "Guidance on Nutrition for Reducing the Risk of Cognitive Decline," which was developed by Eisai under the supervision of the National Center for Geriatrics and Gerontology (NCGG).
Under these initiatives, insights from the Guidance will be incorporated into SIRUTASU's healthcare app "SIRU+," which visualizes nutritional balance and dietary trends based on daily purchasing information, and Wellmira's AI-powered health management app "CALOmama PLUS", which uses personal health records (PHR), including life-log data on diet, exercise and sleep as well as health checkup results, to provide practical health advice tailored to each individual. Through these efforts, Eisai aims to support people in sustainably improving their dietary habits according to their individual nutritional tendencies and lifestyles, thereby contributing to the reduction of the risk of cognitive decline.
Of these initiatives, Eisai's collaboration with SIRUTASU has been selected for the "Orange Innovation Project," which is part of Japan's Ministry of Economy, Trade and Industry's (METI) FY2026 Project for Advancing the Healthcare Industry Infrastructure (Project for Promoting Healthcare Industries in Local Communities). In this project, people living with dementia are positioned as service development partners, and their perspectives will be incorporated into improvements in how information is communicated, usability and food recommendations, and other aspects of the service.
Both services also plan to enable integration, upon user request, with Eisai's "NouKNOW(R)" brain health self-assessment tool (not a medical device) and "Theotol," a portal website providing information on brain health that is operated by Eisai Group company Theoria technologies, Co., Ltd. By promoting awareness of brain health and an accurate understanding of dementia and mild cognitive impairment (MCI), while connecting users to personalized improvements in nutrition and dietary habits and sustained behavioral change, the initiatives will support a continuum of efforts to maintain brain health.
While maintaining drug discovery as its core business, Eisai is promoting the creation of solutions based on science and data to build an hhc ecosystem through collaboration with a diverse range of companies, local governments, healthcare and nursing care stakeholders, and others. Dietary habits are one of the important factors that influence the maintenance of cognitive function. Through these initiatives, Eisai aims to enable each individual to put dietary improvements based on scientific evidence into practice.

About the "Guidance on Nutrition for Reducing the Risk of Cognitive Decline"
Under the supervision of the NCGG, Eisai reviewed domestic and international literature from the perspective of nutritional interventions recommended by the World Health Organization (WHO), and compiled the "Guidance on Nutrition for Reducing the Risk of Cognitive Decline" and the "Guide for Developing Home-Delivered Meals/Meal Kits that Contribute to Reducing the Risk of Cognitive Decline." The Guidance is intended to deepen understanding of dietary patterns that may help reduce the risk of cognitive decline. Related information: https://www.ncgg.go.jp/ri/report/20250203.html
