Started Collaboration with MRT in the area of personal health advice


VELDT Inc. (CEO: Jin Nonogami; Head Office: Shibuya-ku, Tokyo) and MRT Inc.(CEO: Tomoya Ogawa; TSE Growth: 6034) have formed a business alliance in the field of health advice using consumers' lifelog data to support health management needs that are becoming increasingly diversified by lifestyle and region, aiming to realize a world where anyone can easily receive medical care when they feel unwell before becoming ill.

The two companies will collaborate with "Door.", an application provided by MRT Corporation that connects to a network of doctors, and "Data Ethnography™", a health data platform developed by VELDT Inc. that analyzes the relationship between a user's daily habits and environment and their physical condition, to start offering health consultation advice based on personal health data history on November 21. In addition, based on the acquired data, the causal inference function of Data Ethnography™ will be used to propose health promotion measures based on the characteristics of each region to local governments and other organizations that are promoting smart city concepts.

In recent years, in order to realize "Society 5.0" as indicated by the Cabinet Office, companies and local governments in various regions have been actively promoting smart cities. Among these, there is an urgent need to improve the wellness of local communities and reduce medical costs due to the declining birthrate, aging population, and depopulation of rural areas. Further activation of online medical services, the demand for which has grown in the wake of COVID-19, and preventing the occurrence of illnesses through preventive medical checkups and other measures are expected to improve the quality of life in urban areas, extend healthy lifespans, and lower societal costs.

"Data Ethnography ™" developed by VELDT Inc. allows physicians and medical institutions to link their own data, along with health data based on the user's permission, enabling them to see relevance ranking of physical condition and symptoms of illness, and to analyze trends of such. By disclosing personal data to physicians and medical institutions with the user's permission, it is possible to check the health data of individual users as they can be searched using their personal IDs. In addition, by utilizing the causal inference option, the system supports the discovery of hypotheses and virtual verification of previously unseen health factors from various acquired data.

"Door." application provided by MRT is a platform that connects to a network of approximately 80,000 doctors in Japan, and offers a comprehensive "Door.into Health Medical Consultation" service that includes online health consultation, online medical care, and house calls. When you post a message in the application, a doctor will reply to you and start chatting with you, and if necessary, you can also consult with a doctor via video call.

The linkage between "Data Ethnography™" and "Door.into Health Medical Consultation" will enable data analysis that takes into account MRT's accumulated knowledge of individual ailments and illnesses, as well as users' lifestyles, regional characteristics, weather conditions, and other factors. Hypotheses can be segmented by region, and can be used to help care for users in each local community. We hope that this will be a step toward resolving issues in local healthcare, such as the shortage of doctors and rising healthcare costs, and help to promote smart cities, aiming to realize a world where anyone can easily receive more personalized medical care at the point of feeling unwell before they become ill.
