Acquisition of Lightning K.K. Shares

Background and Future Prospects

DS Healthcare Group regards DX (Digital Transformation) of healthcare as an important issue and has been promoting various initiatives. In recent years, DS Healthcare Group has acquired two IT companies through M&A in September 2024, and has established a specialized IT development division within the Group. With the execution of this M&A, we will further strengthen our IT business and accelerate the speed of our operations.

We aim to become a pioneer in data DX for dental care, which is one of the Group's strengths, and to build a system that can contribute to society by promoting DX in the healthcare field.

DX efforts toward universal dental checkups

By computerizing health checkup data and strengthening information linkage, we will build a preventive-centered medical care system that will help improve not only the proper management of the oral cavity but also the overall health of the whole body.

Providing optimal medical care for each individual and extending healthy life expectancy

Data-based medical care support enables the formulation of individualized prevention and treatment plans, and realizes lean and efficient medical care. In addition, by using the accumulated information to disseminate preventive measures based on scientific evidence, the system will not only contribute to maintaining the "ability to eat" and "ability to speak" in an aging society, but also visualize the relationship between dentistry and systemic diseases, thereby contributing to extending healthy life spans.

Correction of medical disparities between regions and ages

By analyzing data collected from across the country, disease trends by region and age can be visualized and utilized for appropriate allocation of medical resources and policy making.

Acceleration of research and technological development

Dental information as big data will contribute to the development of AI-assisted diagnosis technologies and new treatment methods, and will serve as the foundation for shaping the future of healthcare.
